}Virtual reality (VR) experiences can cause a range of negative symptoms such as nausea, disorientation, and oculomotor discomfort, which is collectively called cybersickness. Previous studies have attempted to develop a reliable measure for detecting cybersickness instead of using questionnaires, and electroencephalogram (EEG) has been regarded as one of the possible alternatives. However, despite the increasing interest, little is known about which brain activities are consistently associated with cybersickness and what types of methods should be adopted for measuring discomfort through brain activity. We conducted a scoping review of 33 experimental studies in cybersickness and EEG found through database searches and screening. To understand these studies, we organized the pipeline of EEG analysis into four steps (preprocessing, feature extraction, feature selection, classification) and surveyed the characteristics of each step. The results showed that most studies performed frequency or time-frequency analysis for EEG feature extraction. A part of the studies applied a classification model to predict cybersickness indicating an accuracy between 79 and 100%. These studies tended to use HMD-based VR with a portable EEG headset for measuring brain activity. Most VR content shown was scenic views such as driving or navigating a road, and the age of participants was limited to people in their 20 s. This scoping review contributes to presenting an overview of cybersickness-related EEG research and establishing directions for future work.

}'LightSense - Long Distance' explores remote interaction with architectural space. It is a virtual extension of the project 'LightSense,' which is currently presented at the exhibition 'Cyber Physical: Architecture in Real Time' at EPFL Pavilions in Switzerland. Using numerous VR headsets, the setup at the Art Gallery at SIGGRAPH Asia establishes a direct connection between both exhibition sites in Sydney and Lausanne.'LightSense' at EPFL Pavilions is an immersive installation that allows the audience to engage in intimate interaction with a living architectural body. It consists of a 12-meter-long construction that combines a lightweight structure with projected 3D holographic animations. At its core sits a neural network, which has been trained on sixty thousand poems. This allows the structure to engage, lead, and sustain conversations with the visitor. Its responses are truly associative, unpredictable, meaningful, magical, and deeply emotional. Analysing the emotional tenor of the conversation, 'LightSense' can transform into a series of hybrid architectural volumes, immersing the visitors in Pavilions of Love, Anger, Curiosity, and Joy.'LightSense's' physical construction is linked to a digital twin. Movement, holographic animations, sound, and text responses are controlled by the cloud-based AI system. This combination creates a location-independent cyber-physical system. As such, the 'Long Distance' version, which premiered at SIGGRAPH Asia, enables the visitors in Sydney to directly engage with the physical setup in Lausanne. Using VR headsets with a new 360-degree 4K live streaming system, the visitors find themselves teleported to face 'LightSense', able to engage in a direct conversation with the structure on-site.'LightSense - Long Distance' leaves behind the notion of architecture being a place-bound and static environment. Instead, it points toward the next generation of responsive buildings that transcend space, are capable of dynamic behaviour, and able to accompany their visitors as creative partners.haptic HONGI: Reflections on Collaboration in the Transdisciplinary Creation of an AR Artwork

}We developed the Motion-Simulation Platform, a platform running within a game engine that is able to extract both RGB imagery and the corresponding intrinsic motion data (i.e., motion field). This is useful for motion-related computer vision tasks where large amounts of intrinsic motion data are required to train a model. We describe the implementation and design details of the Motion-Simulation Platform. The platform is extendable, such that any scene developed within the game engine is able to take advantage of the motion data extraction tools. We also provide both user and AI-bot controlled navigation, enabling user-driven input and mass automation of motion data collection.A Motion-Simulation Platform to Generate Synthetic Motion Data for Computer Vision Tasks

}This research investigates fast and precise Virtual Reality (VR) sketching methods with different tool-based asymmetric interfaces. In traditional real-world drawing, artists commonly employ an asymmetric interaction system where each hand holds different tools, facilitating diverse and nuanced artistic expressions. However, in virtual reality (VR), users are typically limited to using identical tools in both hands for drawing. To bridge this gap, we aim to introduce specifically designed tools in VR that replicate the varied tool configurations found in the real world. Hence, we developed a VR sketching system supporting three hybrid input techniques using a standard VR controller, a VR stylus, or a data glove. We conducted a formal user study consisting of an internal comparative experiment with four conditions and three tasks to compare three asymmetric input methods with each other and with a traditional symmetric controller-based solution based on questionnaires and performance evaluations. The results showed that in contrast to symmetric dual VR controller interfaces, the asymmetric input with gestures significantly reduced task completion times while maintaining good usability and input accuracy with a low task workload. This shows the value of asymmetric input methods for VR sketching. We also found that the overall user experience could be further improved by optimizing the tracking stability of the data glove and the VR stylus.ARCOA: using the ar-assisted cooperative assembly system to visualize key information about the occluded partner

}During component assembly, some operations must be completed by two or more workers due to the size or assembly mode. For instance, in manual riveting, two workers are positioned on either side of a steel plate, which blocks the view. Traditional collaborative approaches limit assembly efficiency and is difficult to ensure accurate and rapid interaction between workers. In this study, we developed an AR-Assisted Cooperative Assembly System (ARCoA) to address the issue. ARCoA allows users to view their partner’s key information that is occluded, including tools, gestures, orientations, and shared markers. Besides, we presented a user experiment that compared this method with the traditional approach. The results indicated that the new system could significantly improve assembly efficiency, system availability, and sense of social presence. Moreover, most users we surveyed preferred ARCoA. In the future, we will incorporate more functions and improve the accuracy of the system to solve complex multi-person collaborative problems.A Distributed Augmented Reality Training Architecture For Distributed Cognitive Intelligent Tutoring Paradigms

}Modern training typically incorporates real-world training applications. Augmented Reality (AR) technologies support this by overlaying virtual objects in real-world 3-Dimensional (3D) space. However, integrating instruction into AR is challenging because of technological and educational considerations. One reason is a lack of architecture for supporting Intelligent Tutoring Systems (ITSs) in AR training domains. We present a novel modular agent-based Distributed Augmented Reality Training (DART) architecture for ITSs to address two key AR challenges: (1) a decoupling of the display and tracking components and (2) support for modularity. Modular agents communicate with each other over a network, allowing them to be easily swapped out and replaced to support differing needs. Our motivation is driven by the fact that AR technologies are vary considerably and an ITS architecture would need to be flexible enough to support these requirements. Finally, we believe that our novel architecture will appeal to practical designers of ITSs and to the more theoretical educators who wish to use such systems to simulate and broaden research in the distributed cognitive educational theories.Virtual Reality for Social-Emotional Learning: A Review

}Virtual reality (VR) is an immersive technology that can simulate different environments and experiences. Social-emotional learning (SEL) is a process through which individuals develop the skills, knowledge, and attitudes to understand and manage their emotions, establish positive relationships, and make responsible decisions. SEL promotes healthy emotional regulation in adolescents. However, VR interventions for adolescent emotion regulation have received less attention. The aim of this research is to identify a VR element that includes knowledge in relation to SEL since 2017 through systematic literature reviews (SLRs). A broad review of the current literature was conducted in three databases, namely Scopus, IEEE, and WOS. Data were extracted, including age ranges, year published, and medical procedures, using a search term. The result suggests a requirement list to design a virtual reality for social-emotional learning that promotes a positive impact on emotion regulation for Malaysian adolescents.The MagicBook Revisited

}Twenty years ago the MagicBook demonstrated an early collaborative cross-reality system allowing users to transition along the reality-virtuality continuum. This current application reproduces the key elements of the MagicBook using mobile phones rather than high end graphics computers and custom handheld displays. Just like the original, people can use a handheld viewer to see virtual content superimposed over real book pages, and then fly into the scenes and experience them immersively. Multi-scale collaboration is also supported enabling people in the AR view to see the users in VR, or to experience the scenes together at the same scale. We also add new features, such as realistic avatars, tangible interaction, use of a handheld controller, and support for remote participants. Overall, we have created a cross reality platform that fits in a person’s pocket, but enables them to collaborate with dozens of people in AR and VR in a very natural way. This is demonstrated in a command and control use case, showing its application in a fire-fighting scenario. We also report on pilot study results from people that have tried the platform.Utilizing a Robot to Endow Virtual Objects with Stiffness

}This paper proposes a novel approach to provide stiffness feedback in VR utilizing the inherent characteristics of encounter-type haptic devices (ETHDs). The method aims to provide a sense of object’s deformation and enhance users’ perception of stiffness when touching objects. We explored how to minimize the influence of hardness on stiffness perception and selected materials for the soft, medium, and hard hardness mapping groups to adapt to users’ perceptions when touching objects of different hardness levels. Using this system, we compared and evaluated the method with a touch interaction without stiffness perceptions and found a better performance in terms of realism, possibility to act, attractiveness, efficiency.An Asynchronous Hybrid Cross Reality Collaborative System

}This work presents a Mixed Reality (MR)-based asynchronous hybrid cross reality collaborative system which supports recording and playback of user actions in three-dimensional task space at different periods in time. Using this system, an expert user can record a task process such as virtual object placement or assembly, which can then be viewed by other users in either Augmented Reality (AR) or Virtual Reality (VR) views at later points in time to complete the task. In VR, the pre-scanned 3D workspace can be experienced to enhance the understanding of spatial information. Alternatively, AR can provide real-scale information to help the workers manipulate real world objects, and complete the task assignment. Users can also seamlessly move between AR and VR views as desired. In this way the system can contribute to improving task performance and co-presence during asynchronous collaboration.Time Travellers: An Asynchronous Cross Reality Collaborative System

}This work presents a Mixed Reality (MR)-based asynchronous hybrid cross reality collaborative system which supports recording and playback of user actions in a large task space at different periods in time. Using this system, an expert can record a task process such as virtual object placement or assembly, which can then be viewed by other users in either Augmented Reality (AR) or Virtual Reality (VR) at later points in time to complete the task. In VR, the pre-scanned 3D workspace can be experienced to enhance the understanding of spatial information.

In this way, the system can contribute to improving task performance and co-presence during asynchronous collaboration. The system is demonstrated in a use-case scenario of object assembly using parts that must be retrieved from a storehouse location. A pilot user study found that cross reality asynchronous collaboration system was helpful in providing information about work environments, inducing faster task completion with a lower task load. We provide lessons learned and suggestions for future research.Deep Learning-based Simulator Sickness Estimation from 3D Motion

}This paper presents a novel solution for estimating simulator sickness in HMDs using machine learning and 3D motion data, informed by user-labeled simulator sickness data and user analysis. We conducted a novel VR user study, which decomposed motion data and used an instant dial-based sickness scoring mechanism. We were able to emulate typical VR usage and collect user simulator sickness scores. Our user analysis shows that translation and rotation differently impact user simulator sickness in HMDs. In addition, users’ demographic information and self-assessed simulator sickness susceptibility data are collected and show some indication of potential simulator sickness. Guided by the findings from the user study, we developed a novel deep learning-based solution to better estimate simulator sickness with decomposed 3D motion features and user profile information. The model was trained and tested using the 3D motion dataset with user-labeled simulator sickness and profiles collected from the user study. The results show higher estimation accuracy when using the 3D motion data compared with methods based on optical flow extracted from the recorded video, as well as improved accuracy when decomposing the motion data and incorporating user profile information.Cognitive Load Measurement with Physiological Sensors in Virtual Reality during Physical Activity

}Many Virtual Reality (VR) experiences, such as learning tools, would benefit from utilising mental states such as cognitive load. Increases in cognitive load (CL) are often reflected in the alteration of physiological responses, such as pupil dilation (PD), electrodermal cctivity (EDA), heart rate (HR), and electroencephalography (EEG). However, the relationship between these physiological responses and cognitive load are usually measured while participants sit in front of a computer screen, whereas VR environments often require a high degree of physical movement. This physical activity can affect the measured signals, making it unclear how suitable these measures are for use in interactive Virtual Reality (VR). We investigate the suitability of four physiological measures as correlates of cognitive load in interactive VR. Suitable measures must be robust enough to allow the learner to move within VR and be temporally responsive enough to be a useful metric for adaptation. We recorded PD, EDA, HR, and EEG data from nineteen participants during a sequence memory task at varying levels of cognitive load using VR, while in the standing position and using their dominant arm to play a game. We observed significant linear relationships between cognitive load and PD, EDA, and EEG frequency band power, but not HR. PD showed the most reliable relationship but has a slower response rate than EEG. Our results suggest the potential for use of PD, EDA, and EEG in this type of interactive VR environment, but additional studies will be needed to assess feasibility under conditions of greater movement.Exploring Real-time Precision Feedback for AR-assisted Manual Adjustment in Mechanical Assembly

}Augmented Reality (AR) based manual assembly nowadays enables to guide the process of physical tasks, providing intuitive instructions and detailed information in real-time. However, very limited studies have explored AR manual adjustment tasks with precision requirements. In this paper, we develop an AR-assisted guidance system for manual adjustments with relatively high-precision requirements. We first assessed the accuracy of the special-set OptiTrack system to determine the threshold of precision requirements for our user study. We further evaluated the performance of Number-based and Bar-based precision feedback by comparing orienting assembly errors and task completion time, as well as the usability in the user study. We found that the assembly errors of orientation in the Number-based and Bar-based interfaces were significantly lower than the baseline condition, while there was no significant difference between the Number-based and Bar-based interfaces. Furthermore, the Number-based showed faster task completion time, lower workload, and higher usability than the Bar-based condition.Wearable Augmented Reality: Research Trends and Future Directions from Three Major Venues

}Wearable Augmented Reality (AR) has attracted considerable attention in recent years, as evidenced by the growing number of research publications and industry investments. With swift advancements and a multitude of interdisciplinary research areas within wearable AR, a comprehensive review is crucial for integrating the current state of the field. In this paper, we present a review of 389 research papers on wearable AR, published between 2018 and 2022 in three major venues: ISMAR, TVCG, and CHI. Drawing inspiration from previous works by Zhou et al. and Kim et al., which summarized AR research at ISMAR over the past two decades (1998–2017), we categorize the papers into different topics and identify prevailing trends. One notable finding is that wearable AR research is increasingly geared towards enabling broader consumer adoption. From our analysis, we highlight key observations related to potential future research areas essential for capitalizing on this trend and achieving widespread adoption. These include addressing challenges in Display, Tracking, Interaction, and Applications, and exploring emerging frontiers in Ethics, Accessibility, Avatar and Embodiment, and Intelligent Virtual Agents.Evaluating visual encoding quality of a mixed reality user interface for human–machine co-assembly in complex operational terrain

}During human–machine collaboration in manufacturing activities, it is important to provide real-time annotations in the three-dimensional workspace for local workers who may lack relevant experience and knowledge. For example, in MR assembly, workers need to be alerted to avoid entering hazardous areas when manually replacing components. Recently, many researchers have explored various visual cues for expressing physical task progress information in the MR interface of intelligent systems. However, the relationship between the implantation of visual cues and the balance of interface cognition has not been well revealed, especially in tasks that require annotating hazardous areas in complex operational terrains. In this study, we developed a novel MR interface for an intelligent assembly system that supports local scene sharing based on dynamic 3D reconstruction, remote expert behavior intention recognition based on deep learning, and local personnel operational behavior visual feedback based on external bounding box. We compared the encoding results of the proposed MR interface with 3D annotations combined with 3D sketch cues (3DS), which combines 3D spatial cues (3DSC) and 3DS combined with adaptive cues (AVC), through a case study. We found that for physical tasks that require specific area annotations, 3D annotations with context (3DAC) can better improve the quality of manual work and regulate the cognitive load distribution of the MR interface more reasonably.Older adults’ experiences of social isolation and loneliness: Can virtual touring increase social connectedness?

}The present pilot study explored the research aim of understanding how independent-living older adults experience social isolation and loneliness and whether virtual tour digital technology can increase social connectedness (N = 10). Through triangulation of interviews, experiences, and feedback, this study contributes to the knowledge base on the well-being of our ageing populations and how digital technologies, specifically virtual tourism, can aid in this process. The key findings reveal that the participants in our study were moderately lonely but were open to embracing more digital technology, sharing how it is instrumental in facilitating social connection and life administration. Participating in virtual tour experiences was well accepted as participants expressed enjoyment, nostalgia, and interest in future use. However, its contribution to increasing social connections needs to be clarified and requires further investigation. Several future research and education directions are provided.A comprehensive survey on AR-enabled local collaboration

}With the rapid development of augmented reality (AR) technology and devices, it is widely used in education, design, industry, game, medicine and other fields. It brings new development opportunities for computer-supported cooperative work. In recent years, there has been an increasing number of studies on AR collaboration. Many professional researchers have also summarized and commented on these local and remote applications. However, to the best of our knowledge, there is no comprehensive review specifically on AR-enabled local collaboration (AR-LoCol). Therefore, this paper presents a comprehensive survey of research between 2012 and 2022 in this domain. We surveyed 133 papers on AR-LoCol in Web of Science, 75% of which were published between 2018 and 2022. Next, we provide an in-depth review of papers in seven areas, including time (synchronous and asynchronous), device (hand-held display, desktop, spatial AR, head-mounted display), participants (double and multiple), place (standing, indoor and outdoor), content (virtual objects, annotations, awareness cues and multi-perspective views), and area (education, industry, medicine, architecture, exhibition, game, exterior design, visualization, interaction, basic tools). We discuss the characteristics and specific work in each category, especially the advantages and disadvantages of different devices and the necessity for shared contents. Following this, we summarize the current state of development of AR-LoCol and discuss possible future research directions. This work will be useful for current and future researchers interested in AR-LoCol systems.Investigation of learners’ behavioral intentions to use metaverse learning environment in higher education: a virtual computer laboratory

}The aim of this study is to investigate the determinants that affect undergraduate students’ behavioral intentions to continue learning computer hardware concepts utilizing a Metaverse-based system. The current study examined the factors influencing students’ adoption of Metaverse technology at the tertiary level using a model based on the Technology Acceptance Model (TAM) and the General Extended Technology Acceptance Model for E-Learning (GETAMEL). The data was collected from 210 undergraduate students and Structural Equation Modeling (SEM) was adopted to analyze the responses. The findings show that Perceived Usefulness and Hedonic Motivation have significant positive effect on Behavioral Intention. Additionally, Natural Interaction and Perceived Usefulness significantly affect Hedonic Motivation, while Computer Anxiety negatively affects Hedonic Motivation. Furthermore, Natural Interaction was found to be the strongest predictor of Perceived Usefulness, whereas Experience was the strongest predictor of Perceived Ease of Use. The findings also indicate that Subjective Norms and Self-Efficacy have a significant effect on Experience, while Subjective Norms significantly influence Self-Efficacy. The research results also showed that neither gender nor the department had any effect. The results of this study provide major practical outcomes for higher education institutions and teachers in terms of designing Metaverse-based teaching environments.Immersive medical virtual reality: still a novelty or already a necessity?

}Virtual reality (VR) technologies have been explored for medical applications for over half a century. With major tech companies such as Meta (formerly Facebook), HTC and Microsoft investing heavily in the development of VR technologies, significant advancements have recently been made in hardware (eg, standalone headsets), ease of use (eg, gesture tracking) and equipment cost. These advancements helped spur research in the medical field, with over 2700 VR-related articles indexed in PubMed alone in 2022, and the number of VR articles more than tripling in the last 6 years. Recently, the US Food and Drug Administration (FDA) also approved the first VR-based therapy for chronic back pain. 1 Whether the technology has reached a tipping point for its use in medicine is debatable, but it seems timely to provide a brief overview of the current state of immersive VR in neurology and related fields. In this editorial, we will discuss the characteristics of VR that make it a potentially transformative tool in healthcare, review some of the most mature VR solutions for medical use and highlight barriers to implementation that must be addressed before the technology can be widely adopted in healthcare. This editorial will focus solely on immersive VR technology and will not delve into the applications and use cases of augmented or mixed reality.Can you hear it?

}Most augmented reality (AR) assembly guidance systems only utilize visual information. Regarding the sound, the human binaural effect helps users quickly identify the general direction of sound sources. At the same time, pleasant sounds can give people a sense of pleasure and relaxation. However, the effect on workers is still unknown when stereo sound and visual information are used together for assembly guidance. To assess the combination of sound and vision in AR assembly guidance, we constructed a stereo sound-assisted guidance system (SAG) based on AR. In our SAG system, we used the tone of a soft instrument called the Chinese lute as the sound source. To determine if SAG has an impact on assembly efficiency and user experience, we conducted a usability test to compare SAG with visual information alone. Results showed that the SAG system significantly improves the efficiency of assembly guidance. Moreover, simultaneous visual and auditory information processing does not increase user workload or learning difficulty. Additionally, in a noisy environment, pleasant sounds help to reduce mental strain.A hybrid 2D–3D tangible interface combining a smartphone and controller for virtual reality

}Virtual reality (VR) controllers are widely used for 3D virtual object selection and manipulation in immersive virtual worlds, while touchscreen-based devices like smartphones or tablets provide precise 2D tangible input. However, VR controllers and touchscreens are used separately in most cases. This research physically integrates a VR controller and a smartphone to create a hybrid 2D–3D tangible interface for VR interactions, combining the strength of both devices. The hybrid interface inherits physical buttons, 3D tracking, and spatial input from the VR controller while having tangible feedback, 2D precise input, and content display from the smartphone’s touchscreen. We review the capabilities of VR controllers and smartphones to summarize design principles and then present a design space with nine typical interaction paradigms for the hybrid interface. We developed an interactive prototype and three application modes to demonstrate the combination of individual interaction paradigms in various VR scenarios. We conducted a formal user study through a guided walkthrough to evaluate the usability of the hybrid interface. The results were positive, with participants reporting above-average usability and rating the system as excellent on four out of six user experience questionnaire scales. We also described two use cases to demonstrate the potential of the hybrid interface.Parallel or Cross? Effects of Two Collaborative Modes on Augmented Reality Co-located Operations

}Augmented reality (AR) can bring a new interactive experience to the collaboration between users. When users are in the same place, there are two modes of joint operation for the same object: parallel-work (PW) and cross-work (CW). PW means two users perform their tasks, while CW means assisting each other. To investigate the difference that collaboration using PW and CW in an AR environment brings to users, we developed a two-person local collaboration system, LoCol. We designed and conducted user experiments by selecting the tasks of adjusting the virtual model of the assembly and adding missing boundaries in the model. The results showed that CW led to a higher sense of social coexistence while reducing workload. In terms of task completion time and accuracy, CW and PW each had advantages. We found that users generally want to reduce unnecessary repetitive operations and frequent movement by working with others. This is likely an important criterion for determining who is better suited for a particular job in either approach.Investigating the relationship between three-dimensional perception and presence in virtual reality-reconstructed architecture

}Identifying and characterizing the factors that affect presence in virtual environments has been acknowledged as a critical step to improving Virtual Reality (VR) applications in the built environment domain. In the search to identify those factors, the research objective was to test whether three-dimensional perception affects presence in virtual environments. A controlled within-group experiment utilizing perception and presence questionnaires was conducted, followed by data analysis, to test the hypothesized unidirectional association between three-dimensional perception and presence in two different virtual environments (non-immersive and immersive). Results indicate no association in either of the systems studied, contrary to the assumption of many scholars in the field but in line with recent studies on the topic. Consequently, VR applications in architectural design may not necessarily need to incorporate advanced stereoscopic visualization techniques to deliver highly immersive experiences, which may be achieved by addressing factors other than depth realism. As findings suggest that the levels of presence experienced by users are not subject to the display mode of a 3D model (whether immersive or non-immersive display), it may still be possible for professionals involved in the review of 3D models (e.g., designers, contractors, clients) to experience high levels of presence through non-stereoscopic VR systems provided that other presence-promoting factors are included.Towards an Inclusive and Accessible Metaverse

}The push towards a Metaverse is growing, with companies such as Meta developing their own interpretation of what it should look like. The Metaverse at its conceptual core promises to remove boundaries and borders, becoming a decentralised entity for everyone to use - forming a digital virtual layer over our own “real” world. However, creation of a Metaverse or “new world” presents the opportunity to create one which is inclusive and accessible to all. This challenge is explored and discussed in this workshop, with an aim of understanding how to create a Metaverse which is open and inclusive to people with physical and intellectual disabilities, and how interactions can be designed in a way to minimise disadvantage. The key outcomes of this workshop outline new opportunities for improving accessibility in the Metaverse, methodologies for designing and evaluating accessibility, and key considerations for designing accessible Metaverse environments and interactions.Wish You Were Here: Mental and Physiological Effects of Remote Music Collaboration in Mixed Reality

}With face-to-face music collaboration being severely limited during the recent pandemic, mixed reality technologies and their potential to provide musicians a feeling of "being there" with their musical partner can offer tremendous opportunities. In order to assess this potential, we conducted a laboratory study in which musicians made music together in real-time while simultaneously seeing their jamming partner’s mixed reality point cloud via a head-mounted display and compared mental effects such as flow, affect, and co-presence to an audio-only baseline. In addition, we tracked the musicians’ physiological signals and evaluated their features during times of self-reported flow. For users jamming in mixed reality, we observed a significant increase in co-presence. Regardless of the condition (mixed reality or audio-only), we observed an increase in positive affect after jamming remotely. Furthermore, we identified heart rate and HF/LF as promising features for classifying the flow state musicians experienced while making music together.Brain activity during cybersickness: a scoping review

}Virtual reality (VR) experiences can cause a range of negative symptoms such as nausea, disorientation, and oculomotor discomfort, which is collectively called cybersickness. Previous studies have attempted to develop a reliable measure for detecting cybersickness instead of using questionnaires, and electroencephalogram (EEG) has been regarded as one of the possible alternatives. However, despite the increasing interest, little is known about which brain activities are consistently associated with cybersickness and what types of methods should be adopted for measuring discomfort through brain activity. We conducted a scoping review of 33 experimental studies in cybersickness and EEG found through database searches and screening. To understand these studies, we organized the pipeline of EEG analysis into four steps (preprocessing, feature extraction, feature selection, classification) and surveyed the characteristics of each step. The results showed that most studies performed frequency or time-frequency analysis for EEG feature extraction. A part of the studies applied a classification model to predict cybersickness indicating an accuracy between 79 and 100%. These studies tended to use HMD-based VR with a portable EEG headset for measuring brain activity. Most VR content shown was scenic views such as driving or navigating a road, and the age of participants was limited to people in their 20 s. This scoping review contributes to presenting an overview of cybersickness-related EEG research and establishing directions for future work.The impact of virtual agents’ multimodal communication on brain activity and cognitive load in virtual reality

}Related research has shown that collaborating with Intelligent Virtual Agents (IVAs) embodied in Augmented Reality (AR) or Virtual Reality (VR) can improve task performance and reduce task load. Human cognition and behaviors are controlled by brain activities, which can be captured and reflected by Electroencephalogram (EEG) signals. However, little research has been done to understand users’ cognition and behaviors using EEG while interacting with IVAs embodied in AR and VR environments. In this paper, we investigate the impact of the virtual agent’s multimodal communication in VR on users’ EEG signals as measured by alpha band power. We develop a desert survival game where the participants make decisions collaboratively with the virtual agent in VR. We evaluate three different communication methods based on a within-subject pilot study: 1) a Voice-only Agent, 2) an Embodied Agent with speech and gaze, and 3) a Gestural Agent with a gesture pointing at the object while talking about it. No significant difference was found in the EEG alpha band power. However, the alpha band ERD/ERS calculated around the moment when the virtual agent started speaking indicated providing a virtual body for the sudden speech could avoid the abrupt attentional demand when the agent started speaking. Moreover, a sudden gesture coupled with the speech induced more attentional demands, even though the speech was matched with the virtual body. This work is the first to explore the impact of IVAs’ interaction methods in VR on users’ brain activity, and our findings contribute to the IVAs interaction design.Online platforms for remote immersive Virtual Reality testing: an emerging tool for experimental behavioral research

}Virtual Reality (VR) technology is gaining in popularity as a research tool for studying human behavior. However, the use of VR technology for remote testing is still an emerging field. This study aimed to evaluate the feasibility of conducting remote VR behavioral experiments that require millisecond timing. Participants were recruited via an online crowdsourcing platform and accessed a task on the classic cognitive phenomenon “Inhibition of Return” through a web browser using their own VR headset or desktop computer (68 participants in each group). The results confirm previous research that remote participants using desktop computers can be used effectively for conducting time-critical cognitive experiments. However, inhibition of return was only partially replicated for the VR headset group. Exploratory analyses revealed that technical factors, such as headset type, were likely to significantly impact variability and must be mitigated to obtain accurate results. This study demonstrates the potential for remote VR testing to broaden the research scope and reach a larger participant population. Crowdsourcing services appear to be an efficient and effective way to recruit participants for remote behavioral testing using high-end VR headsets.Using Virtual Replicas to Improve Mixed Reality Remote Collaboration

}In this paper, we explore how virtual replicas can enhance Mixed Reality (MR) remote collaboration with a 3D reconstruction of the task space. People in different locations may need to work together remotely on complicated tasks. For example, a local user could follow a remote expert's instructions to complete a physical task. However, it could be challenging for the local user to fully understand the remote expert's intentions without effective spatial referencing and action demonstration. In this research, we investigate how virtual replicas can work as a spatial communication cue to improve MR remote collaboration. This approach segments the foreground manipulable objects in the local environment and creates corresponding virtual replicas of physical task objects. The remote user can then manipulate these virtual replicas to explain the task and guide their partner. This enables the local user to rapidly and accurately understand the remote expert's intentions and instructions. Our user study with an object assembly task found that using virtual replica manipulation was more efficient than using 3D annotation drawing in an MR remote collaboration scenario. We report and discuss the findings and limitations of our system and study, and present directions for future research.Hapticproxy: Providing positional vibrotactile feedback on a physical proxy for virtual-real interaction in augmented reality

}Consistent visual and haptic feedback is an important way to improve the user experience when interacting with virtual objects. However, the perception provided in Augmented Reality (AR) mainly comes from visual cues and amorphous tactile feedback. This work explores how to simulate positional vibrotactile feedback (PVF) with multiple vibration motors when colliding with virtual objects in AR. By attaching spatially distributed vibration motors on a physical haptic proxy, users can obtain an augmented collision experience with positional vibration sensations from the contact point with virtual objects. We first developed a prototype system and conducted a user study to optimize the design parameters. Then we investigated the effect of PVF on user performance and experience in a virtual and real object alignment task in the AR environment. We found that this approach could significantly reduce the alignment offset between virtual and physical objects with tolerable task completion time increments. With the PVF cue, participants obtained a more comprehensive perception of the offset direction, more useful information, and a more authentic AR experience.Robot-enabled tangible virtual assembly with coordinated midair object placement

}In this paper, we focus on the significance of remote collaboration using virtual replicas, avatar, and gesture on a procedural task in industry; thus, we present a Virtual Reality (VR)/Spatial Augmented Reality (SAR) remote collaboration system, BeHere, based on 3D virtual replicas and sharing gestures and avatar. BeHere enables a remote expert in VR to guide a local worker in real-time to complete a procedural task in the real-world. For the remote VR site, we construct a 3D virtual environment using virtual replicas, and the user can manipulate them by using gestures in an intuitive interaction and see their partners’ 3D virtual avatar. For the local site, we use SAR to enable the local worker to see instructions projected onto the real-world based on the shared virtual replicas and gestures. We conducted a formal user study to evaluate the prototype system in terms of performance, social presence, workload, and ranking and user preference. We found that the combination of visual cues of gestures, avatar, and virtual replicas plays a positive role in improving user experience, especially for remote VR users. More significantly, our study provides useful information and important design implications for further research on the use of gesture-, gaze- and avatar-based cues as well as virtual replicas in VR/AR remote collaboration on a procedural task in industry.RadarHand: a Wrist-Worn Radar for On-Skin Touch-based Proprioceptive Gestures

}We introduce RadarHand, a wrist-worn wearable with millimetre wave radar that detects on-skin touch-based proprioceptive hand gestures. Radars are robust, private, small, penetrate materials, and require low computation costs. We first evaluated the proprioceptive and tactile perception nature of the back of the hand and found that tapping on the thumb is the least proprioceptive error of all the finger joints, followed by the index finger, middle finger, ring finger, and pinky finger in the eyes-free and high cognitive load situation. Next, we trained deep-learning models for gesture classification. We introduce two types of gestures based on the locations of the back of the hand: generic gestures and discrete gestures. Discrete gestures are gestures that start at specific locations and end at specific locations at the back of the hand, in contrast to generic gestures, which can start anywhere and end anywhere on the back of the hand. Out of 27 gesture group possibilities, we achieved 92% accuracy for a set of seven gestures and 93% accuracy for the set of eight discrete gestures. Finally, we evaluated RadarHand’s performance in real-time under two interaction modes: Active interaction and Reactive interaction. Active interaction is where the user initiates input to achieve the desired output, and reactive interaction is where the device initiates interaction and requires the user to react. We obtained an accuracy of 87% and 74% for active generic and discrete gestures, respectively, as well as 91% and 81.7% for reactive generic and discrete gestures, respectively. We discuss the implications of RadarHand for gesture recognition and directions for future works.View Types and Visual Communication Cues for Remote Collaboration

}Over the last several years, remote collaboration has been getting more attention in the research community because of the COVID-19 pandemic. In previous studies, researchers have investigated the effect of adding visual communication cues or shared views in collaboration, but there has not been any previous study exploring the influence between them. In this paper, we investigate the influence of view types on the use of visual communication cues. We compared the use of the three visual cues (hand gesture, a pointer with hand gesture, and sketches with hand gesture) across two view types (dependent and independent views), respectively. We conducted a user study, and the results showed that hand gesture and sketches with the hand gesture cues were well matched with the dependent view condition, and using a pointer with the hand gesture cue was suited to the independent view condition. With the dependent view, the hand gesture and sketch cues required less mental effort for collaborative communication, had better usability, provided better message understanding, and increased feeling of co-presence compared to the independent view. Since the dependent view supported the same viewpoint between the remote expert and a local worker, the local worker could easily understand the remote expert’s hand gestures. In contrast, in the independent view case, when they had different viewpoints, it was not easy for the local worker to understand the remote expert’s hand gestures. The sketch cue had a benefit of showing the final position and orientation of the manipulating objects with the dependent view, but this benefit was less obvious in the independent view case (which provided a further view compared to the dependent view) because precise drawing in the sketches was difficult from a distance. On the contrary, a pointer with the hand gesture cue required less mental effort to collaborate, had better usability, provided better message understanding, and an increased feeling of co-presence in the independent view condition than in the dependent view condition. The pointer cue could be used instead of a hand gesture in the independent view condition because the pointer could still show precise pointing information regardless of the view type.How Immersive Virtual Reality Safety Training System Features Impact Learning Outcomes: An Experimental Study of Forklift Training

}Immersive virtual reality (VR)–based training has been widely proposed in different firms to improve the hazard recognition skills of their workforce and change their unsafe behavior. However, little is known about the impact of VR-based training on the user’s behavior and learning. With the use of structural equation modeling (SEM), this study investigated the impact of VR-based training on 60 participants, and the results supported the mediating effect of VR system features on the users’ acquisition of knowledge, behavioral intention, and satisfaction. The results also indicated that the VR system features were a significant antecedent to psychological factors (presence, motivation, enjoyment, and self-efficacy). This suggests that there are two general paths: (1) usability and fidelity (UF)–enjoyment (EJ)–behavioral intention (BI); and (2) UF–EJ–satisfaction (ST), by which VR-based safety training can have a positive impact on the users’ behavior. This study also revealed that the higher level of presence in the VR training environment would not exert a strong influence on users’ behavior. The findings of this study could help to better design VR-based training programs in a cost-effective way and thus could maximize the benefits of VR technology for industry.How Visualising Emotions Affects Interpersonal Trust and Task Collaboration in a Shared Virtual Space

}Emotion is dynamic. Changes in emotion can be hard to process during face-to-face interaction, yet transferring them into a shared virtual space becomes more challenging. This research first explores nine visual representations to amplify emotions in a virtual space, leading to a bi-directional emotion-sharing system (FeelMoji i/o). The second study investigates the effect of explicit emotion-sharing in interpersonal trust and task collaboration through three conditions - verbal only, verbal+positive visual, and verbal+honest visual using FeelMoji through the proposal of a framework of four factors (usability, integrity, behaviour, and collaboration). The results indicate that FeelMoji yields frequent emotion consensus as task milestones and positive interdependent behaviours between collaborators, which help develop conversations, affirm decision-making, and build familiarity and trust between strangers. Moreover, we discuss how our study can inspire future investigation in human-AI agent behaviours and large-scale multi-user virtual environments.Assessing Superhuman Speed as a Gamified Reward in a Virtual Reality Bike Exergame

}This research presents a Virtual Reality (VR) bike exergame system consisting of a stationed road bike, four novel virtual steering methods, two in-game superhuman speed reward ideas, and a pedalling system simulating real-life resistance. A study is conducted to understand how virtual speed can be used as a reward to encourage enjoyment in physical activities. The result suggests that adding reward-based superhuman speed positively impacts user enjoyment. Adding steering control and increasing speed potentially do not inhibit greater motion sickness symptoms using well-aligned physical-to-virtual input and output representations.Improving real-world skills in people with intellectual disabilities: an immersive virtual reality intervention

}Virtual reality (VR) is a promising tool for training life skills in people with intellectual disabilities. However, there is a lack of evidence surrounding the implementation, suitability, and effectiveness of VR training in this population. The present study investigated the effectiveness of VR training for people with intellectual disabilities by assessing (1) their ability to complete basic tasks in VR, (2) real-world transfer and skill generalisation, and (3) the individual characteristics of participants able to benefit from VR training. Thirty-two participants with an intellectual disability of varying severity completed a waste management training intervention in VR that involved sorting 18 items into three bins. Real-world performance was measured at pre-test, post-test, and delayed time points. The number of VR training sessions varied as training ceased when participants met the learning target (≈ 90% correct). A survival analysis assessed training success probability as a function of the number of training sessions with participants split by their level of adaptive functioning (as measured on the Adaptive Behaviour Assessment System Third Edition). The learning target was met by 19 participants (59.4%) within ten sessions (Mdn = 8.5, IQR 4–10). Real-world performance significantly improved from pre- to post-test and pre- to delayed test. There was no significant difference from post- to delayed test. Further, there was a significant positive relationship between adaptive functioning and change in the real-world assessment from the pre-test to the post- and delayed tests. VR facilitated the learning of most participants, which led to demonstrations of real-world transfer and skill generalisation. The present study identified a relationship between adaptive functioning and success in VR training. The survival curve may assist in planning future studies and training programs.GazeHand: A Gaze-Driven Virtual Hand Interface

}In this paper, we present a novel interface named GazeHand which is designed for distant object interaction in virtual reality. The GazeHand interface translates the virtual hands near to a distant object that the user is looking at and allows direct hand gesture interaction for manipulating an object. Either eye-gaze or head-gaze can be applied to the GazeHand interface to decide the translated positions of the hands. In a user study, we compared these two variants of the GazeHand interface, i.e., Eye-GazeHand and Head-GazeHand, with a baseline condition of a modified Go-Go interface. The results showed that both GazeHand interfaces support the high-level usability of the direct hand operation for distant object interaction while providing the benefits of the gaze interaction: speed and reachability. The two variants of GazeHand interfaces showed better performance than the modified Go-Go interface and the effects were more prominent as the difficulty level of the task increased. The most preferred interface was the Head-GazeHand which took the benefit of a stable head-gaze, while the Eye-GazeHand was less stable using eye-gaze. Meanwhile, the Eye-GazeHand interface showed its advantage over the Head-GazeHand when the task required much gaze movement as it used faster eye-gaze without requiring head movement.Point & Portal: A New Action at a Distance Technique For Virtual Reality

}This paper introduces Point & Portal, a novel Virtual Reality (VR) interaction technique, inspired by Point & Teleport. This new technique enables users to configure portals using pointing actions, and supports seamless action at a distance and navigation without requiring line of sight. By supporting multiple portals, Point & Portalenables users to create dynamic portal configurations to manage multiple remote tasks. Additionally, this paper introduces Relative Portal Positioning for reliable portal interactions, and the concept of maintaining Level Portals. In a comparative user study, Point & Portal demonstrated significant advantages over the traditional Point & Teleport technique to bring interaction devices within-arm’s reach. In the presence of obstacles, Point & Portal exhibited faster speed, lower cognitive load and was preferred by participants. Overall, participants required less physical movement, pointing actions, and reported higher involvement and “good” usability.A User Study on the Comparison of View Interfaces for VR-AR Communication in XR Remote Collaboration

}Previous studies have investigated which context-sharing interfaces are effective in improving task performance; however, consistent results have yet to be found. In this study, we developed a convenient remote collaboration system that provides multiple context-sharing interfaces in a single platform (2D video, 360° video, and 3D reconstruction view). All interfaces can reflect live updates of environmental changes, and we aimed to clarify the effect of the interface on the quality of remote collaboration. Thirty participants were recruited to perform a target-finding-and-placing scenario. Using both objective and subjective metrics, we compared the task performance among the three interface conditions. The results showed that participants completed the task faster and reported a better collaborative experience in the 3D interface condition. Moreover, we found a strong preference for the 3D view interface. These results suggest that providing 3D reconstructed spatial information can enable remote experts to instruct local workers more effectively.Virtual Journalist: Measuring and Inducing Cultural Empathy by Visualizing Empathic Perspectives in VR

}The concept of cultural empathy, which entails the ability to empathize with individuals from diverse cultural backgrounds, has garnered attention across multiple disciplines. However, there has been limited research focusing on the utilization of immersive experiences to deliver journalistic encounters that foster cultural empathy. In this regard, we propose the development of Virtual Journalist, a virtual reality (VR) system that immerses users in the role of a journalist, allowing them to consume 360° video documentaries and capture moments that evoke cultural empathy through photography. Furthermore, this system integrates both cognitive and affective dimensions of empathy by linking physiological data, namely electrodermal activity (EDA) and heart rate variability (HRV), to the captured photographs. Our findings suggest that the impact of Virtual Journalist varies based on the user’s cultural background, and we have observed that empathic accuracy can be achieved by combining user-generated photographs with corresponding physiological data.Striving for Authentic and Sustained Technology Use in the Classroom: Lessons Learned from a Longitudinal Evaluation of a Sensor-Based Science Education Platform

}Technology integration in educational settings has led to the development of novel sensor-based tools that enable students to measure and interact with their environment. Although reports from using such tools can be positive, evaluations are often conducted under controlled conditions and short timeframes. There is a need for longitudinal data collected in realistic classroom settings. However, sustained and authentic classroom use requires technology platforms to be seen by teachers as both easy to use and of value. We describe our development of a sensor-based platform to support science teaching that followed a 14-month design process. We share insights from this design and development approach, and report findings from a six-month large-scale evaluation involving 35 schools and 1245 students. We share lessons learnt, including that technology integration is not an educational goal per se and that technology should be a transparent tool to enable students to achieve their learning goals.- 2022

}We present NapWell, a Sleep Assistant using virtual reality (VR) to decrease sleep onset latency by providing a realistic imagery distraction prior to sleep onset. Our proposed prototype was built using commercial hardware and with relatively low cost, making it replicable for future works as well as paving the way for more low cost EOG-VR devices for sleep assistance. We conducted a user study (n=20) by comparing different sleep conditions; no devices, sleeping mask, VR environment of the study room and preferred VR environment by the participant. During this period, we recorded the electrooculography (EOG) signal and sleep onset time using a finger tapping task (FTT). We found that VR was able to significantly decrease sleep onset latency. We also developed a machine learning model based on EOG signals that can predict sleep onset with a cross-validated accuracy of 70.03%. The presented study demonstrates the feasibility of VR to be used as a tool to decrease sleep onset latency, as well as the use of embedded EOG sensors with VR for automatic sleep detection.

}Radar is primarily used for applications like tracking and large-scale ranging, and its use for object identification has been rarely explored. This paper introduces RaITIn, a radar-based identification (ID) method for tangible interactions. Unlike conventional radar solutions, RaITIn can track and identify objects on a tabletop scale. We use frequency modulated continuous wave (FMCW) radar sensors to classify different objects embedded with low-cost radar reflectors of varying sizes on a tabletop setup. We also introduce Stackable IDs, where different objects can be stacked and combined to produce unique IDs. The result allows RaITIn to accurately identify visually identical objects embedded with different low-cost reflector configurations. When combined with a radar’s ability for tracking, it creates novel tabletop interaction modalities. We discuss possible applications and areas for future work.

}Brain activity sometimes synchronises when people collaborate together on real world tasks. Understanding this process could to lead to improvements in face to face and remote collaboration. In this paper we report on an experiment exploring the relationship between eye gaze and inter-brain synchrony in Virtual Reality (VR). The experiment recruited pairs who were asked to perform finger-tracking exercises in VR with three different gaze conditions: averted, direct, and natural, while their brain activity was recorded. We found that gaze direction has a significant effect on inter-brain synchrony during collaboration for this task in VR. This shows that representing natural gaze could influence inter-brain synchrony in VR, which may have implications for avatar design for social VR. We discuss implications of our research and possible directions for future work.

}Virtual reality provides great opportunities to simulate various environments and situations as reproducible and controllable training environments. Training is an inherently collaborative effort, with trainees and trainers working together to achieve specific goals. Recently, we have seen considerable effort to use virtual training environments (VTEs) in many demanding training contexts, e.g. police training, medical first responder training, firefighter training etc. For such contexts, trainers and trainees must undertake various roles as supervisors, adaptors, role players, and observers in training, making collaboration complex, but essential for training success. These social and multi-user aspects for collaborative VTEs have received little investigation so far. Therefore, we propose this workshop to discuss the potential and perspectives of VTEs for challenging training settings...

}Remote guidance on physical tasks is a type of collaboration in which a local worker is guided by a remote helper to operate on a set of physical objects. It has many applications in industrial sections such as remote maintenance and how to support this type of remote collaboration has been researched for almost three decades. Although a range of different modern computing tools and systems have been proposed, developed and used to support remote guidance in different application scenarios, it is essential to provide communication cues in a shared visual space to achieve common ground for effective communication and collaboration. In this paper, we conduct a selective review to summarize communication cues, approaches that implement the cues and their effects on augmented reality based remote guidance. We also discuss challenges and propose possible future research and development directions.

}The assembly stage is a vital phase in the production process and currently, there are still many manual tasks in the assembly operation. One of the challenges of manual assembly is the issue of blind area assembly since the visual obstruction of the hands or a part can lead to more errors and lower assembly efficiency. In this study, we developed an AR-assisted assembly system that solves the occlusion problem. Assembly workers can use the system to achieve comprehensive and precise hand–eye coordination (HEC). Additionally, we designed and conducted a user evaluation experiment to measure the learnability, usability, and mental effort required for the system for other HEC modes. Results indicate that hand position is the first visual information that should be considered in blind areas. Besides, the Intact HEC mode can effectively reduce the difficulty of learning and mental burden in operation, while at the same time improving efficiency.

}Virtual Reality (VR) interfaces provide an immersive medium to interact with the digital world. Most VR interfaces require physical interactions using handheld controllers, but there are other alternative interaction methods that can support different use cases and users. Interaction methods in VR are primarily evaluated based on their usability, however, their differences in neurological and physiological effects remains less investigated. In this paper—along with other traditional qualitative matrices such as presence, affect, and system usability—we explore the neurophysiological effects—brain signals and electrodermal activity—of using an alternative facial expression interaction method to interact with VR interfaces. This form of interaction was also compared with traditional handheld controllers. Three different environments, with different experiences to interact with were used—happy (butterfly catching), neutral (object picking), and scary (zombie shooting). Overall, we noticed an effect of interaction methods on the gamma activities in the brain and on skin conductance. For some aspects of presence, facial expression outperformed controllers but controllers were found to be better than facial expressions in terms of usability.

}Consistent visual and haptic feedback is an important way to improve the user experience when interacting with virtual objects. However, the perception provided in Augmented Reality (AR) mainly comes from visual cues and amorphous tactile feedback. This work explores how to simulate positional vibrotactile feedback (PVF) with multiple vibration motors when colliding with virtual objects in AR. By attaching spatially distributed vibration motors on a physical haptic proxy, users can obtain an augmented collision experience with positional vibration sensations from the contact point with virtual objects. We first developed a prototype system and conducted a user study to optimize the design parameters. Then we investigated the effect of PVF on user performance and experience in a virtual and real object alignment task in the AR environment. We found that this approach could significantly reduce the alignment offset between virtual and physical objects with tolerable task completion time increments. With the PVF cue, participants obtained a more comprehensive perception of the offset direction, more useful information, and a more authentic AR experience.

}Designing user studies and collecting data is critical to exploring and automatically recognizing human behavior. It is currently possible to use a range of sensors to capture heart rate, brain activity, skin conductance, and a variety of different physiological cues. These data can be combined to provide information about a user’s emotional state, cognitive load, or other factors. However, even when data are collected correctly, synchronizing data from multiple sensors is time-consuming and prone to errors. Failure to record and synchronize data is likely to result in errors in analysis and results, as well as the need to repeat the time-consuming experiments several times. To overcome these challenges, Octopus Sensing facilitates synchronous data acquisition from various sources and provides some utilities for designing user studies, real-time monitoring, and offline data visualization.
The primary aim of Octopus Sensing is to provide a simple scripting interface so that people with basic or no software development skills can define sensor-based experiment scenarios with less effort

}Emotions are complicated psycho-physiological processes that are related to numerous external and internal changes in the body. They play an essential role in human-human interaction and can be important for human-machine interfaces. Automatically recognizing emotions in conversation could be applied in many application domains like health-care, education, social interactions, entertainment, and more. Facial expressions, speech, and body gestures are primary cues that have been widely used for recognizing emotions in conversation. However, these cues can be ineffective as they cannot reveal underlying emotions when people involuntarily or deliberately conceal their emotions. Researchers have shown that analyzing brain activity and physiological signals can lead to more reliable emotion recognition since they generally cannot be controlled. However, these body responses in emotional situations have been rarely explored in interactive tasks like conversations. This paper explores and discusses the performance and challenges of using brain activity and other physiological signals in recognizing emotions in a face-to-face conversation. We present an experimental setup for stimulating spontaneous emotions using a face-to-face conversation and creating a dataset of the brain and physiological activity. We then describe our analysis strategies for recognizing emotions using Electroencephalography (EEG), Photoplethysmography (PPG), and Galvanic Skin Response (GSR) signals in subject-dependent and subject-independent approaches. Finally, we describe new directions for future research in conversational emotion recognition and the limitations and challenges of our approach.

}Virtual Reality (VR) can be used for design and artistic applications. However, traditional symmetrical input devices are not specifically designed as creative tools and may not fully meet artist needs. In this demonstration, we present a variety of tool-based asymmetric VR interfaces to assist artists to create artwork with better performance and easier effort. These interaction methods allow artists to hold different tools in their hands, such as wearing a data glove on the left hand and holding a stylus in the right-hand. We demonstrate this by showing a stylus and glove based sketching interface. We conducted a pilot study showing that most users prefer to create art with different tools in both hands.

In this paper, we present a 360° panoramic Mixed Reality (MR) sys-tem that visualises shared gaze cues using contextual speech input to improve task coordination. We conducted two studies to evaluate the design of the MR gaze-speech interface exploring the combinations of visualisation style and context control level. Findings from the first study suggest that an explicit visual form that directly connects the collaborators’ shared gaze to the contextual conversation is preferred. The second study indicates that the gaze-speech modality shortens the coordination time to attend to the shared interest, making the communication more natural and the collaboration more effective. Qualitative feedback also suggest that having a constant joint gaze indicator provides a consistent bi-directional view while establishing a sense of co-presence during task collaboration. We discuss the implications for the design of collaborative MR systems and directions for future research.

}Recent pandemic-related contact restrictions have made it difficult for musicians to meet in person to make music. As a result, there has been an increased demand for applications that enable remote and real-time music collaboration. One desirable goal here is to give musicians a sense of social presence, to make them feel that they are “on site” with their musical partners. We conducted a focus group study to investigate the impact of remote jamming on users' affect. Further, we gathered user requirements for a Mixed Reality system that enables real-time jamming and developed a prototype based on these findings.Supporting Jury Understanding of Expert Evidence in a Virtual Environment

}This work investigates the use of Virtual Reality (VR) to present forensic evidence to the jury in a courtroom trial. The findings of a between-participant user study on comprehension of an expert statement are presented, examining the benefits and issues of using VR compared to traditional courtroom presentation (being still images). Participants listened to a forensic scientist explain bloodstain spatter patterns while viewing a mock crime scene in either VR or as still images in video format. Under these conditions, we compared understanding of the expert domain, mental effort and content recall. We found that VR significantly improves the understanding of spatial information and knowledge acquisition. We also identify different patterns of user behaviour depending on the display method. We conclude with suggestions on how to best adapt evidence presentation to VR.

In this paper, we share real-time collaborative gaze behaviours, hand pointing, gesturing, and heart rate visualisations between remote collaborators using a live 360 ° panoramic-video based Mixed Reality (MR) system. We first ran a pilot study to explore visual designs to combine communication cues with biofeedback (heart rate), aiming to understand user perceptions of empathic collaboration. We then conducted a formal study to investigate the effect of modality (Gaze+Hand, Hand-only) and interface (Near-Gaze, Embodied). The results show that the Gaze+Hand modality in a Near-Gaze interface is significantly better at reducing task load, improving co-presence, enhancing understanding and tightening collaborative behaviours compared to the conventional Embodied hand-only experience. Ranked as the most preferred condition, the Gaze+Hand in Near-Gaze condition is perceived to reduce the need for dividing attention to the collaborator’s physical location, although it feels slightly less natural compared to the embodied visualisations. In addition, the Gaze+Hand conditions also led to more joint attention and less hand pointing to align mutual understanding. Lastly, we provide a design guideline to summarize what we have learned from the studies on the representation between modality, interface, and biofeedback.

}Researchers have employed hyperscanning, a technique used to simultaneously record neural activity from multiple participants, in real-world collaborations. However, to the best of our knowledge, there is no study that has used hyperscanning in Virtual Reality (VR). The aims of this study were; firstly, to replicate results of inter-brain synchrony reported in existing literature for a real world task and secondly, to explore whether the inter-brain synchrony could be elicited in a Virtual Environment (VE). This paper reports on three pilot-studies in two different settings (real-world and VR). Paired participants performed two sessions of a finger-pointing exercise separated by a finger-tracking exercise during which their neural activity was simultaneously recorded by electroencephalography (EEG) hardware. By using Phase Locking Value (PLV) analysis, VR was found to induce similar inter-brain synchrony as seen in the real-world. Further, it was observed that the finger-pointing exercise shared the same neurally activated area in both the real-world and VR. Based on these results, we infer that VR can be used to enhance inter-brain synchrony in collaborative tasks carried out in a VE. In particular, we have been able to demonstrate that changing visual perspective in VR is capable of eliciting inter-brain synchrony. This demonstrates that VR could be an exciting platform to explore the phenomena of inter-brain synchrony further and provide a deeper understanding of the neuroscience of human communication.

}Virtual Reality (VR) Head-Mounted Display (HMD) technology immerses a user in a computer generated virtual environment. However, a VR HMD also blocks the users’ view of their physical surroundings, and so prevents them from using their mobile phones in a natural manner. In this paper, we present a novel Augmented Virtuality (AV) interface that enables people to naturally interact with a mobile phone in real time in a virtual environment. The system allows the user to wear a VR HMD while seeing his/her 3D hands captured by a depth sensor and rendered in different styles, and enables the user to operate a virtual mobile phone aligned with their real phone. We conducted a formal user study to compare the AV interface with physical touch interaction on user experience in five mobile applications. Participants reported that our system brought the real mobile phone into the virtual world. Unfortunately, the experiment results indicated that using a phone with our AV interfaces in VR was more difficult than the regular smartphone touch interaction, with increased workload and lower system usability, especially for a typing task. We ran a follow-up study to compare different hand visualizations for text typing using the AV interface. Participants felt that a skin-colored hand visualization method provided better usability and immersiveness than other hand rendering styles.

}This paper describes a modular framework developed to facilitate the design space exploration of cross-device Augmented Reality (AR) interfaces that combine an AR head-mounted display (HMD) with a smartphone. Currently, there is a growing interest in how AR HMDs can be used with smartphones to improve the user’s AR experience. In this work, we describe a framework that enables rapid prototyping and evaluation of an interface. Our system enables different modes of interaction, content placement, and simulated AR HMD field of view to assess which combination is best suited to inform future researchers on design recommendations. We provide examples of how the framework could be used to create sample applications, the types of the studies which could be supported, and example results from a simple pilot study.

}Gaze is one of the predominant communication cues and can provide valuable implicit information such as intention or focus when performing collaborative tasks. However, little research has been done on how virtual gaze cues combining spatial and temporal characteristics impact real-life physical tasks during face to face collaboration. In this study, we explore the effect of showing joint gaze interaction in an Augmented Reality (AR) interface by evaluating three bi-directional collaborative (BDC) gaze visualisations with three levels of gaze behaviours. Using three independent tasks, we found that all bi-directional collaborative BDC visualisations are rated significantly better at representing joint attention and user intention compared to a non-collaborative (NC) condition, and hence are considered more engaging. The Laser Eye condition, spatially embodied with gaze direction, is perceived significantly more effective as it encourages mutual gaze awareness with a relatively low mental effort in a less constrained workspace. In addition, by offering additional virtual representation that compensates for verbal descriptions and hand pointing, BDC gaze visualisations can encourage more conscious use of gaze cues coupled with deictic references during co-located symmetric collaboration. We provide a summary of the lessons learned, limitations of the study, and directions for future research.

}The art installation common/room explores human‐digital‐human encounter across cultural differences. It comprises a suite of extended reality (XR) experiences that use technology as a bridge to help support human connections with a view to overcoming intercultural discomfort (racism). The installations are exhibited as an informal dining room, where each table hosts a distinct experience designed to bring people together in a playful yet meaningful way. Each experience uses different technologies, including 360° 3D virtual reality (VR) in a headset (common/place), 180° 3D projection (Common Sense) and augmented reality (AR) (Come to the Table! and First Contact ‐ Take 2). This article focuses on the latter, First Contact ‐ Take 2, in which visitors are invited to sit at a dining table, wear an AR head-mounted display and encounter a recorded volumetric representation of an Indigenous Māori woman seated opposite them. She speaks directly to the visitor out of a culture that has refined collective endeavour and relational psychology over millennia. The contextual and methodological framework for this research is international commons scholarship and practice that sits within a set of relationships outlined by the Mātike Mai Report on constitutional transformation for Aotearoa, New Zealand.

}This demonstration presents ShowMeAround, a video conferencing system designed to allow people to give virtual tours over live 360-video. Using ShowMeAround a host presenter walks through a real space and can live stream a 360-video view to a small group of remote viewers. The ShowMeAround interface has features such as remote pointing and viewpoint awareness to support natural collaboration between the viewers and host presenter. The system also enables sharing of pre-recorded high resolution 360 video and still images to further enhance the virtual tour experience.

}Avatars are common virtual representations used in Extended Reality (XR) to support interaction and communication between remote collaborators. Recent advancements in wearable displays provide features such as eye and face-tracking, to enable avatars to express non-verbal cues in XR. The research in this paper investigates the impact of avatar visualization on Social Presence and user’s preference by simulating face tracking in an asymmetric XR remote collaboration between a desktop user and a Virtual Reality (VR) user. Our study was conducted between pairs of participants, one on a laptop computer supporting face tracking and the other being immersed in VR, experiencing different visualization conditions. They worked together to complete an island survival task. We found that the users preferred 3D avatars with facial expressions placed in the scene, compared to 2D screen attached avatars without facial expressions. Participants felt that the presence of the collaborator’s avatar improved overall communication, yet Social Presence was not significantly different between conditions as they mainly relied on audio for communication.

}Proprioception is the body’s ability to sense the position and movement of each limb, as well as the amount of effort exerted onto or by them. Methods to assess proprioception have been introduced before, yet there is little to no study on assessing the degree of proprioception on body parts for use cases like gesture recognition wearable computing. We propose the use of Fitts’ law coupled with the N-Back task to evaluate proprioception of the hand. We evaluate 15 distinct points at the back of the hand and assess the musing extended 3D Fitts’ law. Our results show that the index of difficulty of tapping point from thumb to pinky increases gradually with a linear regression factor of 0.1144. Additionally, participants perform the tap before performing the N-Back task. From these results, we discuss the fundamental limitations and suggest how Fitts’ law can be further extended to assess proprioception

}We present XRTeleBridge (XRTB), an application that integrates a Mixed Reality (MR) interface into existing teleconferencing solutions like Zoom. Unlike conventional webcam, XRTB provides a window into the virtual world to demonstrate and visualize content. Participants can join via webcam or via head mounted display (HMD) in a Virtual Reality (VR) environment. It enables users to embody 3D avatars with natural gestures and eye gaze. A camera in the virtual environment operates as a video feed to the teleconferencing software. An interface resembling a tablet mirrors the teleconferencing window inside the virtual environment, thus enabling the participant in the VR environment to see the webcam participants in real-time. This allows the presenter to view and interact with other participants seamlessly. To demonstrate the system’s functionalities, we created a virtual chemistry lab environment and presented an example lesson using the virtual space and virtual objects and effects.

}Hyperscanning is an emerging method for measuring two or more brains simultaneously. This method allows researchers to simultaneously record neural activity from two or more people. While this method has been extensively implemented over the last five years in the real-world to study inter-brain synchrony, there is little work that has been undertaken in the use of hyperscanning in virtual environments. Preliminary research in the area demonstrates that inter-brain synchrony in virtual environments can be achieved in a mannersimilar to thatseen in the real world. The study described in this paper proposes to further research in the area by studying how non-verbal communication cues in social interactions in virtual environments can afect inter-brain synchrony. In particular, we concentrate on the role eye gaze playsin inter-brain synchrony. The aim of this research is to explore how eye gaze afects inter-brain synchrony between users in a collaborative virtual environment

Video: https://www.youtube.com/watch?v=FVk5lWtntGkMainstream Virtual Reality (VR) devices on the market nowadays mostly use symmetric interaction design for input, yet common practice by artists suggests asymmetric interaction using different input tools in each hand could be a better alternative for 3D modeling tasks in VR. In this paper, we explore the performance and usability of a tool-based asymmetric interaction method for a 3D object selection task in VR and compare it with a symmetric interface. The symmetric VR interface uses two identical handheld controllers to select points on a sphere, while the asymmetric interface uses a handheld controller and a stylus. We conducted a user study to compare these two interfaces and found that the asymmetric system was faster, required less workload, and was rated with better usability. We also discuss the opportunities for tool-based asymmetric input to optimize VR art workflows and future research directions.eyemR-Talk: Using Speech to Visualise Shared MR Gaze Cues

}Mental health conditions pose a major challenge to healthcare providers and society at large. Early intervention can have significant positive impact on a person's prognosis, particularly important in improving mental health outcomes and functioning for young people. Virtual Reality (VR) in mental health is an emerging and innovative field. Recent studies support the use of VR technology in the treatment of anxiety, phobia, eating disorders, addiction, and pain management. However, there is little research on using VR for supporting, treatment and prevention of depression - a field that is very much emerging. There is also very little work done in offering individualised VR experience to users with mental health issues. This paper proposes iVR, a novel individualised VR for improving users' self-compassion, and in the long run, their positive mental health. We describe the concept, design, architecture and implementation of iVR and outline future work. We believe this contribution will pave the way for large-scale efficacy testing, clinical use, and potentially cost-effective delivery of VR technology for mental health therapy in future.

}Supporting natural communication cues is critical for people to work together remotely and face-to-face. In this paper we present a Mixed Reality (MR) remote collaboration system that enables a local worker to share a live 3D panorama of his/her surroundings with a remote expert. The remote expert can also share task instructions back to the local worker using visual cues in addition to verbal communication. We conducted a user study to investigate how sharing augmented gaze and gesture cues from the remote expert to the local worker could affect the overall collaboration performance and user experience. We found that by combing gaze and gesture cues, our remote collaboration system could provide a significantly stronger sense of co-presence for both the local and remote users than using the gaze cue alone. The combined cues were also rated significantly higher than the gaze in terms of ease of conveying spatial actions.

}In this paper, we propose OmniGlobeVR, a novel collaboration tool based on an asymmetric cooperation system that supports communication and cooperation between a VR user (occupant) and multiple non-VR users (designers) across the virtual and physical platform. The OmniGlobeVR allows designer(s) to access the content of a VR space from any point of view using two view modes: 360° first-person mode and third-person mode. Furthermore, a proper interface of a shared gaze awareness cue is designed to enhance communication between the occupant and the designer(s). The system also has a face window feature that allows designer(s) to share their facial expressions and upper body gesture with the occupant in order to exchange and express information in a nonverbal context. Combined together, the OmniGlobeVR allows collaborators between the VR and non-VR platforms to cooperate while allowing designer(s) to easily access physical assets while working synchronously with the occupant in the VR space.

}Locomotion in virtual reality (VR) is one of the biggest problems for large scale adoption of VR applications. Yet, to our knowledge, there are few studies conducted in-the-wild to understand performance metrics and general user preference for different mechanics. In this paper, we present the first steps towards an open framework to create a VR locomotion benchmark. As a viability study, we investigate how well the users move in VR when using three different locomotion mechanics. It was played in over 124 sessions across 10 countries in a period of three weeks. The included prototype locomotion mechanics are arm swing,walk-in-place and trackpad movement. We found that over-all, users performed significantly faster using arm swing and trackpad when compared to walk-in-place. For subjective preference, arm swing was significantly more preferred over the other two methods. Finally for induced sickness, walk-in-place was the overall most sickness-inducing locomotion method.

}Navigation with passive haptic feedback can enhance users’ immersion in virtual environments. We propose a constrained path redirection method to provide users with corresponding haptic feedback at the right time and place. We have quantified the VR exploration practicality in a study and the results show advantages over steer-to-center method in terms of presence, and over Steinicke’s method in terms of matching errors and presence.

}Presence, the feeling of being there, is an important factor that affects the overall experience of virtual reality. Presence is measured through post-experience subjective questionnaires. While questionnaires are a widely used method in human-based research, they suffer from participant biases, dishonest answers, and fatigue. In this paper, we measured the effects of different levels of presence (high and low) in virtual environments using physiological and neurological signals as an alternative method. Results indicated a significant effect of presence on both physiological and neurological signals.

}With the advancement of Artificial Intelligence technology to make smart devices, understanding how humans develop trust in virtual agents is emerging as a critical research field. Through our research, we report on a novel methodology to investigate user’s trust in auditory assistance in a Virtual Reality (VR) based search task, under both high and low cognitive load and under varying levels of agent accuracy. We collected physiological sensor data such as electroencephalography (EEG), galvanic skin response (GSR), and heart-rate variability (HRV), subjective data through questionnaire such as System Trust Scale (STS), Subjective Mental Effort Questionnaire (SMEQ) and NASA-TLX. We also collected a behavioral measure of trust (congruency of users’ head motion in response to valid/ invalid verbal advice from the agent). Our results indicate that our custom VR environment enables researchers to measure and understand human trust in virtual agents using the matrices, and both cognitive load and agent accuracy play an important role in trust formation. We discuss the implications of the research and directions for future work.

}Research on Augmented Reality (AR)/Mixed Reality (MR) remote collaboration for physical tasks remains a compelling and dynamic area of study. AR systems have been developed which transmit virtual annotations between remote collaborators, but there has been little research on how haptic feedback can also be shared. In this paper, we present a Virtual Reality (VR)-Spatial Augmented Reality (SAR) remote collaborative system that provides haptic feedback with tangible interaction between a local worker and a remote expert helper. Using this system, we conducted a within-subject user study to compare two interfaces for remote collaboration between a local worker and expert helper, one with mid-air free drawing (MFD) and one with tangible physical drawing (TPD). The results showed that there were no significant differences with respect to performance time and operation errors. However, users felt that the TPD interface supporting passive haptic feedback could significantly improve the remote experts’ user experience in VR. Our research provides useful information on the way for gesture- and gaze-based multimodal interaction supporting haptic feedback in AR/MR remote collaboration on physical tasks.

}Communication disruptions are frequent in aerial firefighting. Information is more easily lost over multiple radio channels, busy with simultaneous conversations. Such a high bandwidth of information throughput creates mental overload. Further problems with hardware or radio signals being disrupted over long distances or by mountainous terrain make it difficult to coordinate firefighting efforts. This creates stressful conditions and requires certain expertise to manage effectively. An experiment was conducted which tested the effects of disrupting users communications equipment and measured their stress levels as well as communication performance. This research investigated how realistic communication disruptions have an effect on behavioural changes in communication frequency, as well as physiological stress by means of measuring heart rate variability (HRV). Broken radio transmissions created a greater degree of stress than background chatter alone. Experts could maintain a more stable HRV during disruptions than novices, which was calculated on the change in HRV during the experiment. From this, we deduce that experts have a better ability to manage stress. We also noted strategies employed by experts such as relaying to overcome the radio challenges, as opposed to novices who would not find a solution, effectively giving up.

}The aim of this research was to examine the effect of Augmented Reality (AR) supported geometry teaching on students’ 3D thinking skills. This research consisted of 3 steps: (1) developing a 3D thinking ability scale, (ii) design and development of an AR Geometry Tutorial System (ARGTS) and (iii) implementation and assessment of geometry teaching supported with ARGTS. A 3D thinking ability scale was developed and tested with experimental and control groups as a pre- and post-test evaluation. An AR Geometry Tutorial System (ARGTS) and AR teaching materials and environments were developed to enhance 3D thinking skills. A user study with these materials found that geometry teaching supported by ARGTS significantly increased the students’ 3D thinking skills. The increase in average scores of Structuring 3D arrays of cubes and Calculation of the volume and the area of solids thinking skills was not statistically significant (p > 0.05). In terms of other 3D geometric thinking skills’ subfactors of the scale a statistically significant difference was found in favour of the experimental group in pre-test and post-test scores (p < 0.05). The biggest difference was found on ability to recognize and create 3D shapes (p < 0.01).The results of this research are particularly important for identifying individual differences in 3D thinking skills of secondary school students and creating personalized dynamic intelligent learning environments.

}Augmented Reality (AR) offers an enhanced learning environment which could potentially influence children's experience and knowledge gain during the language learning process. Teaching English or other foreign languages to children with different native language can be difficult and requires an effective strategy to avoid boredom and detachment from the learning activities. With the growing numbers of AR education applications and the increasing pervasiveness of speech recognition, we are keen to understand how these technologies benefit non-native young children in learning English. In this paper, we explore children's experience in terms of knowledge gain and enjoyment when learning through a combination of AR and speech recognition technologies. We developed a prototype AR interface called TeachAR, and ran two experiments to investigate how effective the combination of AR and speech recognition was towards the learning of 1) English terms for color and shapes, and 2) English words for spatial relationships. We found encouraging results by creating a novel teaching strategy using these two technologies, not only in terms of increase in knowledge gain and enjoyment when compared with traditional strategy but also enables young children to finish the certain task faster and easier.

}Researchers have employed hyperscanning, a technique used to simultaneously record neural activity from multiple participants, in real-world collaborations. However, to the best of our knowledge, there is no study that has used hyperscanning in Virtual Reality (VR). The aims of this study were; firstly, to replicate results of inter-brain synchrony reported in existing literature for a real world task and secondly, to explore whether the inter-brain synchrony could be elicited in a Virtual Environment (VE). This paper reports on three pilot-studies in two different settings (real-world and VR). Paired participants performed two sessions of a finger-pointing exercise separated by a finger-tracking exercise during which their neural activity was simultaneously recorded by electroencephalography (EEG) hardware. By using Phase Locking Value (PLV) analysis, VR was found to induce similar inter-brain synchrony as seen in the real-world. Further, it was observed that the finger-pointing exercise shared the same neurally activated area in both the real-world and VR. Based on these results, we infer that VR can be used to enhance inter-brain synchrony in collaborative tasks carried out in a VE. In particular, we have been able to demonstrate that changing visual perspective in VR is capable of eliciting inter-brain synchrony. This demonstrates that VR could be an exciting platform to explore the phenomena of inter-brain synchrony further and provide a deeper understanding of the neuroscience of human communication.

}Brain synchronicity is a neurological phenomena where two or more individuals have their brain activation in phase when performing a shared activity. We present NeuralDrum, an extended reality (XR) drumming experience that allows two players to drum together while their brain signals are simultaneously measured. We calculate the Phase Locking Value (PLV) to determine their brain synchronicity and use this to directly affect their visual and auditory experience in the game, creating a closed feedback loop. In a pilot study, we logged and analysed the users’ brain signals as well as had them answer a subjective questionnaire regarding their perception of synchronicity with their partner and the overall experience. From the results, we discuss design implications to further improve NeuralDrum and propose methods to integrate brain synchronicity into interactive experiences.

Innovative technologies such as Augmented Reality (AR) and Virtual Reality, tangible user interfaces (TUIs), computer games, robotics and microprocessors have seen an interest within educational research due to their potential for fostering active learning in and outside the classroom. This paper aims to explore the affordances of AR and TUIs as mediums of instruction to address the problem of teaching and learning text-based computer languages, computer science concepts, and programming skills such as debugging. It presents parallels between the technology-supported learning and the active, scaffolded narrative entertainment experience in videogames, and suggests a conceptual framework for the design of learning environments for programming and debugging by using AR and tangible interaction to support scaffolding.

}Remote collaboration using mixed reality (MR) enables two separated workers to collaborate by sharing visual cues. A local worker can share his/her environment to the remote worker for a better contextual understanding. However, prior techniques were using either 360 video sharing or a complicated 3D reconstruction configuration. This limits the interactivity and practicality of the system. In this paper we show an interactive and easy-to-configure MR remote collaboration technique enabling a local worker to easily share his/her environment by integrating 360 panorama images into a low-cost 3D reconstructed scene as photo-bubbles and projective textures. This enables the remote worker to visit past scenes on either an immersive 360 panoramic scenery, or an interactive 3D environment. We developed a prototype and conducted a user study comparing the two modes of how 360 panorama images could be used in a remote collaboration system. Results suggested that both photo-bubbles and projective textures can provide high social presence, co-presence and low cognitive load for solving tasks while each have its advantage and limitations. For example, photo-bubbles are good for a quick navigation inside the 3D environment without depth perception while projective textures are good for spatial understanding but require physical efforts.

}In this study, the relationship between the usability of a mobile Augmented Reality (AR) tutorial system and cognitive load was examined. In this context, the relationship between perceived usefulness, the perceived ease of use, and the perceived natural interaction factors and intrinsic, extraneous, germane cognitive load were investigated. In addition, the effect of gender on this relationship was investigated. The research results show that there was a strong relationship between the perceived ease of use and the extraneous load in males, and there was a strong relationship between the perceived usefulness and the intrinsic load in females. Both the perceived usefulness and the perceived ease of use had a strong relationship with the germane cognitive load. Moreover, the perceived natural interaction had a strong relationship with the perceived usefulness in females and the perceived ease of use in males. This research will provide significant clues to AR software developers and researchers to help reduce or control cognitive load in the development of AR-based instructional software.

}Many systems have been developed to support remote guidance, where a local worker manipulates objects under guidance of a remote expert helper. These systems typically use speech and visual cues between the local worker and the remote helper, where the visual cues could be pointers, hand gestures, or sketches. However, the effects of combining visual cues together in remote collaboration has not been fully explored. We conducted a user study comparing remote collaboration with an interface that combined hand gestures and sketching (the HandsInTouch interface) to one that only used hand gestures, when solving two tasks; Lego assembly and repairing a laptop. In the user study, we found that (1) adding sketch cues improved the task completion time, only with the repairing task as this had complex object manipulation but (2) using gesture and sketching together created a higher task load for the user.

}Current remote collaborative systems in manufacturing are mainly based on video-conferencing technology. Their primary aim is to transmit manufacturing process knowledge between remote experts and local workers. However, it does not provide the experts with the same hands-on experience as when synergistically working on site in person. The mixed reality (MR) and increasing networking performances have the capacity to enhance the experience and communication between collaborators in geographically distributed locations. In this paper, therefore, we propose a new gesture-based remote collaborative platform using MR technology that enables a remote expert to collaborate with local workers on physical tasks. Besides, we concentrate on collaborative remote assembly as an illustrative use case. The key advantage compared to other remote collaborative MR interfaces is that it projects the remote expert’s gestures into the real worksite to improve the performance, co-presence awareness, and user collaboration experience. We aim to study the effects of sharing the remote expert’s gestures in remote collaboration using a projector-based MR system in manufacturing. Furthermore, we show the capabilities of our framework on a prototype consisting of a VR HMD, Leap Motion, and a projector. The prototype system was evaluated with a pilot study comparing with the POINTER (adding AR annotations on the task space view through the mouse), which is the most popular method used to augment remote collaboration at present. The assessment adopts the following aspects: the performance, user’s satisfaction, and the user-perceived collaboration quality in terms of the interaction and cooperation. Our results demonstrate a clear difference between the POINTER and 2.5DHANDS interface in the performance time. Additionally, the 2.5DHANDS interface was statistically significantly higher than the POINTER interface in terms of the awareness of user’s attention, manipulation, self-confidence, and co-presence.

}Augmented and Virtual Reality provide unique capabilities for Mixed Reality collaboration. This paper explores how different combinations of virtual awareness cues can provide users with valuable information about their collaborator's attention and actions. In a user study (n = 32, 16 pairs), we compared different combinations of three cues: Field-of-View (FoV) frustum, Eye-gaze ray, and Head-gaze ray against a baseline condition showing only virtual representations of each collaborator's head and hands. Through a collaborative object finding and placing task, the results showed that awareness cues significantly improved user performance, usability, and subjective preferences, with the combination of the FoV frustum and the Head-gaze ray being best. This work establishes the feasibility of room-scale MR collaboration and the utility of providing virtual awareness cues.

}Collaborative Mixed Reality (MR) systems are at a critical point in time as they are soon to become more commonplace. However, MR technology has only recently matured to the point where researchers can focus deeply on the nuances of supporting collaboration, rather than needing to focus on creating the enabling technology. In parallel, but largely independently, the field of Computer Supported Cooperative Work (CSCW) has focused on the fundamental concerns that underlie human communication and collaboration over the past 30-plus years. Since MR research is now on the brink of moving into the real world, we reflect on three decades of collaborative MR research and try to reconcile it with existing theory from CSCW, to help position MR researchers to pursue fruitful directions for their work. To do this, we review the history of collaborative MR systems, investigating how the common taxonomies and frameworks in CSCW and MR research can be applied to existing work on collaborative MR systems, exploring where they have fallen behind, and look for new ways to describe current trends. Through identifying emergent trends, we suggest future directions for MR, and also find where CSCW researchers can explore new theory that more fully represents the future of working, playing and being with others.

}When engaged in communication, people often rely on pointing gestures to refer to out-of-reach content. However, observers frequently misinterpret the target of a pointing gesture. Previous research suggests that to perform a pointing gesture, people place the index finger on or close to a line connecting the eye to the referent, while observers interpret pointing gestures by extrapolating the referent using a vector defined by the arm and index finger. In this paper we present Warping Deixis, a novel approach to improving the perception of pointing gestures and facilitate communication in collaborative Extended Reality environments. By warping the virtual representation of the pointing individual, we are able to match the pointing expression to the observer’s perception. We evaluated our approach in a colocated side by side virtual reality scenario. Results suggest that our approach is effective in improving the interpretation of pointing gestures in shared virtual environments.

}Background: A key assumption of VR training is that the learned skills and experiences transfer to the real world. Yet, in certain application areas, such as VR sports training, the research testing this assumption is sparse. Design: Real-world table tennis performance was assessed using a mixed-model analysis of variance. The analysis comprised a between-subjects (VR training group vs control group) and a within-subjects (pre- and post-training) factor. Method: Fifty-seven participants (23 females) were either assigned to a VR training group (n = 29) or no-training control group (n = 28). During VR training, participants were immersed in competitive table tennis matches against an artificial intelligence opponent. An expert table tennis coach evaluated participants on real-world table tennis playing before and after the training phase. Blinded regarding participant’s group assignment, the expert assessed participants’ backhand, forehand and serving on quantitative aspects (e.g. count of rallies without errors) and quality of skill aspects (e.g. technique and consistency). Results: VR training significantly improved participants’ real-world table tennis performance compared to a no-training control group in both quantitative (p < .001, Cohen’s d = 1.08) and quality of skill assessments (p < .001, Cohen’s d = 1.10). Conclusions: This study adds to a sparse yet expanding literature, demonstrating real-world skill transfer from Virtual Reality in an athletic task

The Miniature is immersed in a 360-video shared by the Giant who can physically manipulate the Miniature through a tangible interface, a combined 360-camera with a 6 DOF tracker. We implemented a prototype system as a proof of concept and conducted a user study (n=24) comprising of four parts comparing: A) two types of virtual representations, B) three levels of Miniature control, C) three levels of 360-video view dependencies, and D) four 360-camera placement positions on the Giant. The results show users prefer a shoulder mounted camera view, while a view frustum with a complimentary avatar is a good visualization for the Miniature virtual representation. From the results, we give design recommendations and demonstrate an example Giant-Miniature Interaction.

}Many researchers have studied various visual communication cues (e.g. pointer, sketching, and hand gesture) in Mixed Reality remote collaboration systems for real-world tasks. However, the effect of combining them has not been so well explored. We studied the effect of these cues in four combinations: hand only, hand + pointer, hand + sketch, and hand + pointer + sketch, with three problem tasks: Lego, Tangram, and Origami. The study results showed that the participants completed the task significantly faster and felt a significantly higher level of usability when the sketch cue is added to the hand gesture cue, but not with adding the pointer cue. Participants also preferred the combinations including hand and sketch cues over the other combinations. However, using additional cues (pointer or sketch) increased the perceived mental effort and did not improve the feeling of co-presence. We discuss the implications of these results and future research directions.

}Remote Collaboration using Virtual Reality (VR) and Augmented Reality (AR) has recently become a popular way for people from different places to work together. Local workers can collaborate with remote helpers by sharing 360-degree live video or 3D virtual reconstruction of their surroundings. However, each of these techniques has benefits and drawbacks. In this paper we explore mixing 360 video and 3D reconstruction together for remote collaboration, by preserving benefits of both systems while reducing drawbacks of each. We developed a hybrid prototype and conducted user study to compare benefits and problems of using 360 or 3D alone to clarify the needs for mixing the two, and also to evaluate the prototype system. We found participants performed significantly better on collaborative search tasks in 360 and felt higher social presence, yet 3D also showed potential to complement. Participant feedback collected after trying our hybrid system provided directions for improvement.

}Augmented Reality (AR) offers an enhanced learning environment which could potentially influence children's experience and knowledge gain during the language learning process. Teaching English or other foreign languages to children with different native language can be difficult and requires an effective strategy to avoid boredom and detachment from the learning activities. With the growing numbers of AR education applications and the increasing pervasiveness of speech recognition, we are keen to understand how these technologies benefit non-native young children in learning English. In this paper, we explore children's experience in terms of knowledge gain and enjoyment when learning through a combination of AR and speech recognition technologies. We developed a prototype AR interface called TeachAR, and ran two experiments to investigate how effective the combination of AR and speech recognition was towards the learning of 1) English terms for color and shapes, and 2) English words for spatial relationships. We found encouraging results by creating a novel teaching strategy using these two technologies, not only in terms of increase in knowledge gain and enjoyment when compared with traditional strategy but also enables young children to finish the certain task faster and easier.

}In this paper, we explore the effect of showing a remote partner close to user gaze point in a teleconferencing system. We implemented a gaze following function in a teleconferencing system and investigate if this improves the user's feeling of emotional interdependence. We developed a prototype system that shows a remote partner close to the user's current gaze point and conducted a user study comparing it to a condition displaying the partner fixed in the corner of a screen. Our results showed that showing a partner close to their gaze point helped users feel a higher level of emotional interdependence. In addition, we compared the effect of our method between small and big displays, but there was no significant difference in the users' feeling of emotional interdependence even though the big display was preferred.

}We propose enhancing live 360 panorama-based Mixed Reality (MR) remote collaboration through supporting visual annotation cues. Prior work on live 360 panorama-based collaboration used MR visualization to overlay visual cues, such as view frames and virtual hands, yet they were not registered onto the shared physical workspace, hence had limitations in accuracy for pointing or marking objects. Our prototype system uses spatial mapping and tracking feature of an Augmented Reality head-mounted display to show visual annotation cues accurately registered onto the physical environment. We describe the design and implementation details of our prototype system, and discuss on how such feature could help improve MR remote collaboration.

}Virtual Reality (VR) is effective in various training scenarios across multiple domains, such as education, health and defense. However, most of those applications are not adaptive to the real-time cognitive or subjectively experienced load placed on the trainee. In this paper, we explore a cognitively adaptive training system based on real-time measurement of task related alpha activity in the brain. This measurement was made by a 32-channel mobile Electroencephalography (EEG) system, and was used to adapt the task difficulty to an ideal level which challenged our participants, and thus theoretically induces the best level of performance gains as a result of training. Our system required participants to select target objects in VR and the complexity of the task adapted to the alpha activity in the brain. A total of 14 participants undertook our training and completed 20 levels of increasing complexity. Our study identified significant differences in brain activity in response to increasing levels of task complexity, but response time did not alter as a function of task difficulty. Collectively, we interpret this to indicate the brain's ability to compensate for higher task load without affecting behaviourally measured visuomotor performance.

}Binaural spatialization over a bone conduction headset in the vertical plane was investigated using inexpensive and commercially available hardware and software components. The aim of the study was to assess the acuity of binaurally spatialized presentations in the vertical plane. The level of externalization achievable was also explored. Results demonstrate good correlation between established perceptual traits for headphone based auditory localization using non-individualized HRTFs, though localization accuracy appears to be significant worse. A distinct pattern of compressed localization judgments is observed with participants tending to localize the presented stimulus within an approximately 20° range on either side of the inter-aural plane. Localization error was approximately 21° in the vertical plane. Participants reported a good level of externalization. We’ve been able to demonstrate an acceptable level of spatial resolution and externalization is achievable using an inexpensive bone conduction headset and software components.

}This paper investigates how two different unique gaze visualizations (the head pointer(HP), eye gaze(EG)) affect table-size physical tasks in Mixed Reality (MR) remote collaboration. We developed a remote collaborative MR Platform which supports sharing of the remote expert's HP and EG. The prototype was evaluated with a user study comparing two conditions: sharing HP and EG with respect to their effectiveness in the performance and quality of cooperation. There was a statistically significant difference between two conditions on the performance time, and HP is a good proxy for EG in remote collaboration.

}In this study, the relationship was investigated between self‐esteem and loneliness in social networks among students in a guidance and psychological counselling teaching department. The study was conducted during the 2017‐2018 academic year with 312 trainee school counsellors from Turkey. In terms of data collection, the Social Network Loneliness Scale, and the Self‐esteem Scale were employed, and a statistical analysis of the data was conducted. We found a negative relationship between self‐esteem and loneliness as experienced in social networks, although neither differs according to sex, age and class level. It was also found that those who use the Internet for communication purposes have high levels of loneliness and self‐esteem in social networks. While self‐esteem levels among users of the Internet are high, those who use it to read about or watch the news have high levels of loneliness. No relationship was found between self‐ esteem and social network loneliness levels and among those who use the Internet for playing games. Regular sporting habits were found to have a positive effect on self‐esteem, but no effect on the level of loneliness in social networks.

}For more than 2 decades, Augmented Reality (AR)/Mixed Reality (MR) has received an increasing amount of attention by researchers and practitioners in the manufacturing community, because it has applications in many fields, such as product design, training, maintenance, assembly, and other manufacturing operations. However, to the best of our knowledge, there has been no comprehensive review of AR-based co-design in manufacturing. This paper presents a comprehensive survey of existing research, projects, and technical characteristics between 1990 and 2017 in the domain of co-design based on AR technology. Among these papers, more than 90% of them were published between 2000 and 2017, and these recent relevant works are discussed at length. The paper provides a comprehensive academic roadmap and useful insight into the state-of-the-art of AR-based co-design systems and developments in manufacturing for future researchers all over the world. This work will be useful to researchers who plan to utilize AR as a tool for design research.

}This paper examines mathematics teachers’ level of acceptance and intention to use the Augmented Reality Geometry Tutorial System (ARGTS), a mobile Augmented Reality (AR) application developed to enhance students’ 3D geometric thinking skills. ARGTS was shared with mathematics teachers, who were then surveyed using the Technology Acceptance Model (TAM) to understand their acceptance of the technology. We also examined the external variables of Anxiety, Social Norms and Satisfaction. The effect of the teacher’s gender, degree of graduate status and number of years of teaching experience on the subscales of the TAM model were examined. We found that the Perceived Ease of Use (PEU) had a direct effect on the Perceived Usefulness (PU) in accordance with the Technology Acceptance Model (TAM). Both variables together affect Satisfaction (SF), however PEU had no direct effect on Attitude (AT). In addition, while Social Norms (SN) had a direct effect on PU and PEU, there was no direct effect on Behavioural Intention (BI). Anxiety (ANX) had a direct effect on PEU, but no effect on PU and SF. While there was a direct effect of SF on PEU, no direct effect was found on BI. We explain how the results of this study could help improve the understanding of AR acceptance by teachers and provide important guidelines for AR researchers, developers and practitioners.

}The aim of this research was to examine the effect of Augmented Reality (AR) supported geometry teaching on students’ 3D thinking skills. This research consisted of 3 steps: (1) developing a 3D thinking ability scale, (ii) design and development of an AR Geometry Tutorial System (ARGTS) and (iii) implementation and assessment of geometry teaching supported with ARGTS. A 3D thinking ability scale was developed and tested with experimental and control groups as a pre- and post-test evaluation. An AR Geometry Tutorial System (ARGTS) and AR teaching materials and environments were developed to enhance 3D thinking skills. A user study with these materials found that geometry teaching supported by ARGTS significantly increased the students’ 3D thinking skills. The increase in average scores of Structuring 3D arrays of cubes and Calculation of the volume and the area of solids thinking skills was not statistically significant (p > 0.05). In terms of other 3D geometric thinking skills’ subfactors of the scale a statistically significant difference was found in favour of the experimental group in pre-test and post-test scores (p < 0.05). The biggest difference was found on ability to recognize and create 3D shapes (p < 0.01).The results of this research are particularly important for identifying individual differences in 3D thinking skills of secondary school students and creating personalized dynamic intelligent learning environments.

}We have explored the effects of sharing manipulated heart rate feedback in collaborative virtual environments. In our study, we created two types of different virtual environments (active and passive) with different levels of interactions and provided three levels of manipulated heart rate feedback (decreased, unchanged, and increased). We measured the effects of manipulated feedback on Social Presence, affect, physical heart rate, and overall experience. We noticed a significant effect of the manipulated heart rate feedback in affecting scariness and nervousness. The perception of the collaborator's valance and arousal was also affected where increased heart rate feedback perceived as a higher valance and lower arousal. Increased heart rate feedback decreased the real heart rate. The type of virtual environments had a significant effect on social presence, heart rate, and affect where the active environment had better performances across these measurements. We discuss the implications of this and directions for future research.

}Mixed Reality (MR) remote collaboration provides an enhanced immersive experience where a remote user can provide verbal and nonverbal assistance to a local user to increase the efficiency and performance of the collaboration. This is usually achieved by sharing the local user's environment through live 360 video or a 3D scene, and using visual cues to gesture or point at real objects allowing for better understanding and collaborative task performance. While most of prior work used one of the methods to capture the surrounding environment, there may be situations where users have to choose between using 360 panoramas or 3D scene reconstruction to collaborate, as each have unique benefits and limitations. In this paper we designed a prototype system that combines 360 panoramas into a 3D scene to introduce a novel way for users to interact and collaborate with each other. We evaluated the prototype through a user study which compared the usability and performance of our proposed approach to live 360 video collaborative system, and we found that participants enjoyed using different ways to access the local user's environment although it took them longer time to learn to use our system. We also collected subjective feedback for future improvements and provide directions for future research.

}Inter-brain connectivity between pairs of people was explored during a finger tracking task in the real-world and in Virtual Reality (VR). This was facilitated by the use of a dual EEG set-up that allowed us to use hyperscanning to simultaneously record the neural activity of both participants. We found that similar levels of inter-brain synchrony can be elicited in the real-world and VR for the same task. This is the first time that hyperscanning has been used to compare brain activity for the same task performed in real and virtual environments.

}Mixed Reality (MR) remote collaboration provides an enhanced immersive experience where a remote user can provide verbal and nonverbal assistance to a local user to increase the efficiency and performance of the collaboration. This is usually achieved by sharing the local user's environment through live 360 video or a 3D scene, and using visual cues to gesture or point at real objects allowing for better understanding and collaborative task performance. While most of prior work used one of the methods to capture the surrounding environment, there may be situations where users have to choose between using 360 panoramas or 3D scene reconstruction to collaborate, as each have unique benefits and limitations. In this paper we designed a prototype system that combines 360 panoramas into a 3D scene to introduce a novel way for users to interact and collaborate with each other. We evaluated the prototype through a user study which compared the usability and performance of our proposed approach to live 360 video collaborative system, and we found that participants enjoyed using different ways to access the local user's environment although it took them longer time to learn to use our system. We also collected subjective feedback for future improvements and provide directions for future research.

Research has shown that Mixed Presence Groupware (MPG) systems are a valuable collaboration tool. However research into MPG systems is limited to a handful of tabletop and Virtual Reality (VR) systems with no exploration of Head-Mounted Display (HMD) based Augmented Reality (AR) solutions. We present a new system with two local users and one remote user using HMD based AR interfaces. Our system provides tools allowing users to layout a room with the help of a remote user. The remote user has access to a marker and pointer tools to assist in directing the local users. Feedback collected from several groups of users showed that our system is easy to learn but could have increased accuracy and consistency.

[download]We present Mini-Me, an adaptive avatar for enhancing Mixed Reality (MR) remote collaboration between a local Augmented Reality (AR) user and a remote Virtual Reality (VR) user. The Mini-Me avatar represents the VR user's gaze direction and body gestures while it transforms in size and orientation to stay within the AR user's field of view. A user study was conducted to evaluate Mini-Me in two collaborative scenarios: an asymmetric remote expert in VR assisting a local worker in AR, and a symmetric collaboration in urban planning. We found that the presence of the Mini-Me significantly improved Social Presence and the overall experience of MR collaboration.

Video: https://youtu.be/nCX8zIEmv0sHead and eye movement can be leveraged to improve the user's interaction repertoire for wearable displays. Head movements are deliberate and accurate, and provide the current state-of-the-art pointing technique. Eye gaze can potentially be faster and more ergonomic, but suffers from low accuracy due to calibration errors and drift of wearable eye-tracking sensors. This work investigates precise, multimodal selection techniques using head motion and eye gaze. A comparison of speed and pointing accuracy reveals the relative merits of each method, including the achievable target size for robust selection. We demonstrate and discuss example applications for augmented reality, including compact menus with deep structure, and a proof-of-concept method for on-line correction of calibration drift.

Video: https://youtu.be/GZzC0Vhte4MThis paper presents ongoing work on a design exploration for mixed-scale gestures, which interleave microgestures with larger gestures for computer interaction. We describe three prototype applications that show various facets of this multi-dimensional design space. These applications portray various tasks on a Hololens Augmented Reality display, using different combinations of wearable sensors. Future work toward expanding the design space and exploration is discussed, along with plans toward evaluation of mixed-scale gesture design.

The Levity system measures and interactively adjusts the display of a visual array during a visual search task based on the user's level of cognitive load, measured with a 16-channel EEG device. Future developments will validate the system and evaluate its ability to improve search efficiency by detecting and adapting to a user's cognitive demands.

Video: https://youtu.be/W-CDpBqe1yIWe describe a method and a prototype implementation for filtering shared social data (eg, 360 video) in a wearable Augmented Reality (eg, HoloLens) application. The data filtering is based on user-viewer relationships. For example, when sharing a 360 video, if the user has an intimate relationship with the viewer, then full fidelity (ie the 360 video) of the user's environment is visible. But if the two are strangers then only a snapshot image is shared. By varying the fidelity of the shared content, the viewer is able to focus more on the data shared by their close relations and differentiate this from other content. Also, the approach enables the sharing-user to have more control over the fidelity of the content shared with their contacts for privacy.

}Augmented Reality (AR) interfaces have been studied extensively over the last few decades, with a growing number of user-based experiments. In this paper, we systematically review 10 years of the most influential AR user studies, from 2005 to 2014. A total of 291 papers with 369 individual user studies have been reviewed and classified based on their application areas. The primary contribution of the review is to present the broad landscape of user-based AR research, and to provide a high-level view of how that landscape has changed. We summarize the high-level contributions from each category of papers, and present examples of the most influential user studies. We also identify areas where there have been few user studies, and opportunities for future research. Among other things, we find that there is a growing trend toward handheld AR user studies, and that most studies are conducted in laboratory settings and do not involve pilot testing. This research will be useful for AR researchers who want to follow best practices in designing their own AR user studies.

}In a team, the strong bonds that can form between teammates are often seen as critical for reaching peak performance. This perspective may need to be reconsidered, however, if some team members are autonomous robots since establishing bonds with fundamentally inanimate and expendable objects may prove counterproductive. Previous work has measured empathic responses towards robots as singular events at the conclusion of experimental sessions. As relationships extend over long periods of time, sustained empathic behavior towards robots would be of interest. In order to measure user actions that may vary over time and are affected by empathy towards a robot teammate, we created the TEAMMATE simulation system. Our findings suggest that inducing empathy through a back story narrative can significantly change participant decisions in actions that may have consequences for a robot companion over time. The results of our study can have strong implications for the overall performance of human machine teams.

Our remote collaboration system shares a live video of a local user's real-world task space with a remote user. The remote user can have an independent view or a dependent view of a shared real-world object manipulation task and can draw virtual annotations onto the real-world objects as a visual communication cue. With the system, we investigated two different collaboration styles; (1) remote expert collaboration where a remote user has the solution and gives instructions to a local partner and (2) mutual collaboration where neither user has a solution but both remote and local users share ideas and discuss ways to solve the real-world task. In the user study, the remote expert collaboration showed a number of benefits over the mutual collaboration. With the remote expert collaboration, participants had better communication from the remote user to the local user, more aligned focus between participants, and the remote participants' feeling of enjoyment and togetherness. However, the benefits were not always apparent at the local participants' end, especially with measures of enjoyment and togetherness. The independent view also had several benefits over the dependent view, such as allowing remote participants to freely navigate around the workspace while having a wider fully zoomed-out view.

Reliable fiducials are strongly desired for many augmented reality (AR) applications, but currently there is no systematic method to design highly reliable fiducials. In this paper, we present fiducial marker optimizer (FMO), a tool to optimize the design attributes of ARToolKit markers, including black to white (B:W) ratio, edge sharpness, and information complexity, and to reduce inter-marker confusion. For these operations, the FMO provides a user friendly interface at the front-end and specialized image processing algorithms at the back-end. We tested manually designed markers and FMO optimized markers in ARToolKit and found that the latter were more robust. The FMO will be used for designing highly reliable fiducials in easy to use fashion. It will improve the application's performance, where it is used.

}In this paper, we investigate hand gestures and visual annotation cues overlaid in a live 360 panorama-based Mixed Reality remote collaboration. The prototype system captures 360 live panorama video of the surroundings of a local user and shares it with another person in a remote location. The two users wearing Augmented Reality or Virtual Reality head-mounted displays can collaborate using augmented visual communication cues such as virtual hand gestures, ray pointing, and drawing annotations. Our preliminary user evaluation comparing these cues found that using visual annotation cues (ray pointing and drawing annotation) helps local users perform collaborative tasks faster, easier, making less errors and with better understanding, compared to using only virtual hand gestures.

}Situation Awareness (SA) is an essential skill in Air Attack Supervision (AAS) for aerial based wildfire firefighting. The display types used for Virtual Reality Training Systems (VRTS) afford different visual SA depending on the Field of View (FoV) as well as the sense of presence users can obtain in the virtual environment. We conducted a study with 36 participants to evaluate SA acquisition in three display types: a high-definition TV (HDTV), an Oculus Rift Head-Mounted Display (HMD) and a 270° cylindrical simulation projection display called the SimPit. We found a significant difference between the HMD and the HDTV, as well as with the SimPit and the HDTV for the three levels of SA.

}In 2008, Zhou et al. presented a survey paper summarizing the previous ten years of ISMAR publications, which provided invaluable insights into the research challenges and trends associated with that time period. Ten years later, we review the research that has been presented at ISMAR conferences since the survey of Zhou et al., at a time when both academia and the AR industry are enjoying dramatic technological changes. Here we consider the research results and trends of the last decade of ISMAR by carefully reviewing the ISMAR publications from the period of 2008-2017, in the context of the first ten years. The numbers of papers for different research topics and their impacts by citations were analyzed while reviewing them-which reveals that there is a sharp increase in AR evaluation and rendering research. Based on this review we offer some observations related to potential future research areas or trends, which could be helpful to AR researchers and industry members looking ahead.

}This paper showcases one way of how virtual reconstruction can be used in a courtroom. The results of a pilot study on narrative and spatial memory are presented in the context of viewing real and virtual copies of a simulated crime scene. Based on current court procedures, three different viewing options were compared: photographs, a real life visit, and a 3D virtual reconstruction of the scene viewed in a Virtual Reality headset. Participants were also given a written narrative that included the spatial locations of stolen goods and were measured on their ability to recall and understand these spatial relationships of those stolen items. The results suggest that Virtual Reality is more reliable for spatial memory compared to photographs and that Virtual Reality provides a compromise for when physical viewing of crime scenes are not possible. We conclude that Virtual Reality is a promising medium for the court.

}Previous research has demonstrated that Augmented Reality can reduce a user's task response time and mental effort when completing a procedural task. This paper investigates techniques to improve user performance and reduce mental effort by providing projector-based Spatial Augmented Reality predictive cues for future responses. The objective of the two experiments conducted in this study was to isolate the performance and mental effort differences from several different annotation cueing techniques for simple (Experiment 1) and complex (Experiment 2) button-pressing tasks. Comporting with existing cognitive neuroscience literature on prediction, attentional orienting, and interference, we hypothesized that for both simple procedural tasks and complex search-based tasks, having a visual cue guiding to the next task's location would positively impact performance relative to a baseline, no-cue condition. Additionally, we predicted that direction-based cues would provide a more significant positive impact than target-based cues. The results indicated that providing a line to the next task was the most effective technique for improving the users' task time and mental effort in both the simple and complex tasks.

}The advancements in Mixed Reality (MR), Unmanned Aerial Vehicle, and multi-scale collaborative virtual environments have led to new interface opportunities for remote collaboration. This paper explores a novel concept of flying telepresence for multi-scale mixed reality remote collaboration. This work could enable remote collaboration at a larger scale such as building construction. We conducted a user study with three experiments. The first experiment compared two interfaces, static and dynamic IPD, on simulator sickness and body size perception. The second experiment tested the user perception of a virtual object size under three levels of IPD and movement gain manipulation with a fixed eye height in a virtual environment having reduced or rich visual cues. Our last experiment investigated the participant’s body size perception for two levels of manipulation of the IPDs and heights using stereo video footage to simulate a flying telepresence experience. The studies found that manipulating IPDs and eye height influenced the user’s size perception. We present our findings and share the recommendations for designing a multi-scale MR flying telepresence interface.

}Augmented Reality overlays virtual objects on the real world in real-time and has the potential to enhance education, however, few AR training systems provide personalised learning support. Combining AR with intelligent tutoring systems has the potential to improve training outcomes by providing personalised learner support, such as feedback on the AR environment. This paper reviews the current state of AR training systems combined with ITSs and proposes a series of requirements for combining the two paradigms. In addition, this paper identifies a growing need to provide more research in the context of design and implementation of adaptive augmented reality tutors (ARATs). These include possibilities of evaluating the user interfaces of ARAT and potential domains where an ARAT might be considered effective.

}Wildfire firefighting is difficult to train for in the real world due to a variety of reasons, cost and environmental impact being the major barriers to effective training. Virtual Reality offers greater training opportunities to practice crucial skills, difficult to obtain without experiencing the actual environment. Situation Awareness (SA) is a critical aspect of Air Attack Supervision (AAS). Timely decisions need to be made by the AAS based on the information gathered while airborne. The type of display used in virtual reality training systems afford different levels of SA due to factors such as field of view, as well as presence within the virtual environment and the system. We conducted a study with 36 participants to evaluate SA acquisition and immersion in three display types: a high-definition TV (HDTV), an Oculus Rift Head-Mounted Display (HMD) and a 270° cylindrical projection system (SimPit). We found a significant difference between the HMD and the HDTV, as well as with the SimPit and the HDTV for SA levels. Preference was given more to the HMD for immersion and portability, but the SimPit gave the best environment for the actual role.

}Many of the problems being addressed by Immersive Analytics require groups of people to solve. This chapter introduces the concept of Collaborative Immersive Analytics (CIA) and reviews how immersive technologies can be combined with Visual Analytics to facilitate co-located and remote collaboration. We provide a definition of Collaborative Immersive Analytics and then an overview of the different types of possible collaboration. The chapter also discusses the various roles in collaborative systems, and how to support shared interaction with the data being presented. Finally, we summarize the opportunities for future research in this domain. The aim of the chapter is to provide enough of an introduction to CIA and key directions for future research, so that practitioners will be able to begin working in the field.

}Aerial firefighting takes place in stressful environments where decision making and communication are paramount, and skills need to be practiced and trained regularly. An experiment was performed to test the effects of disrupting the communications ability of the users on their stress levels in a noisy environment. The goal of this research is to investigate how realistic disruption of communication systems can be simulated in a virtual environment and to what extent they induce stress. We found that aerial firefighting experts maintained a better Heart Rate Variability (HRV) during disruptions than novices. Experts showed better ability to manage stress based on the change in HRV during the experiment. Our main finding is that communication disruptions in virtual reality (e.g., broken transmissions) significantly impacted the level of stress experienced by participants.

}Strong empathic bonding between members of a team can elevate team performance tremendously but it is not clear how such bonding within human-machine teams may impact upon mission success. Prior work using self-reporting surveys and end-of-task metrics do not capture how such bonding may evolve over time and impact upon task fulfillment. Furthermore, sensor-based measures do not scale easily to facilitate the need to collect substantial data for measuring potentially subtle effects. We introduce TEAMMATE, a system designed to provide insights into the emotional dynamics humans may form for machine teammates that could critically impact upon the design of human machine teams.

}Augmented Reality (AR) supports natural interaction in physical and virtual worlds, so it has recently given rise to a number of novel interaction modalities. This paper presents a method for using hand-gestures with speech input for multimodal interaction in AR. It focuses on providing an intuitive AR environment which supports natural interaction with virtual objects while sustaining accessible real tasks and interaction mechanisms. The paper reviews previous multimodal interfaces and describes recent studies in AR that employ gesture and speech inputs for multimodal input. It describes an implementation of gesture interaction with speech input in AR for virtual object manipulation. Finally, the paper presents a user evaluation of the technique, showing that it can be used to improve the interaction between virtual and physical elements in an AR environment.

We implemented a prototype system for capturing and sharing facial expression between VR players through their avatar. We describe our current prototype system and how it could be assimilated into a system for enhancing social VR experience. Two social VR games were created for a preliminary user study. We discuss our findings from the user study, potential games for this system, and future directions for this research.

}Virtual environments have been proven to be effective in evoking emotions. Earlier research has found that physiological data is a valid measurement of the emotional state of the user. Being able to see one’s physiological feedback in a virtual environment has proven to make the application more enjoyable. In this paper, we have investigated the effects of manipulating heart rate feedback provided to the participants in a single user immersive virtual environment. Our results show that providing slightly faster or slower real-time heart rate feedback can alter participants’ emotions more than providing unmodified feedback. However, altering the feedback does not alter real physiological signals.

}In this study we present a Mixed-Reality based mobile remote collaboration system that enables an expert providing real-time assistance over a physical distance. By using the Google ARCore position tracking, we can integrate the keyframes captured with one external depth sensor attached to the mobile phone as one single 3D point-cloud data set to present the local physical environment into the VR world. This captured local scene is then wirelessly streamed to the remote side for the expert to view while wearing a mobile VR headset (HTC VIVE Focus). In this case, the remote expert can immerse himself/herself in the VR scene and provide guidance just as sharing the same work environment with the local worker. In addition, the remote guidance is also streamed back to the local side as an AR cue overlaid on top of the local video see-through display. Our proposed mobile remote collaboration system supports a pair of participants performing as one remote expert guiding one local worker on some physical tasks in a more natural and efficient way in a large scale work space from a distance by simulating the face-to-face co-work experience using the Mixed-Reality technique.

}It has been observed that a robot shown as suffering is enough to cause an empathic response from a person. Whether the response is a fleeting reaction with no consequences or a meaningful perspective change with associated behavior modifications is not clear. Existing work has been limited to measurements made at the end of empathy inducing experimental trials rather measurements made over time to capture consequential behavioral pattern. We report on preliminary results collected from a study that attempts to measure how the actions of a participant may be altered by empathy for a robot companion. Our findings suggest that induced empathy can in fact have a significant impact on a person's behavior to the extent that the ability to fulfill a mission may be affected.

}We ran a pilot study to investigate the impact of video placement in augmented reality conferencing on communication, social presence and user preference. In addition, we explored the influence of different tasks, assembly and negotiation. We discovered a correlation between video placement and the type of the tasks, with some significant results in social presence indicators.

}Many systems have been developed to support remote collaboration, where hand gestures or sketches can be shared. However, the effect of combining gesture and sketching together has not been fully explored and understood. In this paper we describe HandsInTouch, a system in which both hand gestures and sketches made by a remote helper are shown to a local user in real time. We conducted a user study to test the usability of the system and the usefulness of combing gesture and sketching for remote collaboration. We discuss results and make recommendations for system design and future work.

}As computer-based training systems become increasingly integrated into real-world training, tools which rapidly author courses for such systems are emerging. However, inconsistent user interface design and limited support for a variety of domains makes them time consuming and difficult to use. We present a Generalized, Rapid Authoring Tool (GRAT), which simplifies creation of Intelligent Tutoring Systems (ITSs) using a unified web-based wizard-style graphical user interface and programming-by-demonstration approaches to reduce technical knowledge needed to author ITS logic. We implemented a prototype, which authors courses for two kinds of tasks: A network cabling task and a console device configuration task to demonstrate the tool's potential. We describe the limitations of our prototype and present opportunities for evaluating the tool's usability and perceived effectiveness.

}Recent development of affordable head-mounted displays (HMDs) has led to accessible Virtual Reality (VR) solutions for watching 360-degree panoramic movies. While conventionally users cannot see their body while watching 360 movies, our prior work seamlessly blended a user's physical body into a 360 virtual movie scene. This paper extends this work by overlaying context-matching virtual costumes onto the user's real body. A prototype was developed using a pair of depth cameras and an HMD to capture the user's real body and embed it into a virtual 360 movie scene. Virtual costumes related to the movie scene are then overlaid on user's real body to enhance the user experience. Results from a user study showed that augmenting the user's real body with context-matching virtual costume was most preferred by users while having no significant effect on sense of presence compared to showing only user's body in a 360 movie scene. The results offer a future direction to generate enhanced 360 VR movie watching experiences.

}This paper describes two user studies in remote collaboration between two users with a video conferencing system where a remote user can draw annotations on the live video of the local user’s workspace. In these two studies, the local user had the control of the view when sharing the first-person view, but our interfaces provided instant control of the shared view to the remote users. The first study investigates methods for assisting drawing annotations. The auto-freeze method, a novel solution for drawing annotations, is compared to a prior solution (manual freeze method) and a baseline (non-freeze) condition. Results show that both local and remote users preferred the auto-freeze method, which is easy to use and allows users to quickly draw annotations. The manual-freeze method supported precise drawing, but was less preferred because of the need for manual input. The second study explores visual notification for better local user awareness. We propose two designs: the red-box and both-freeze notifications, and compare these to the baseline, no notification condition. Users preferred the less obtrusive red-box notification that improved awareness of when annotations were made by remote users, and had a significantly lower level of interruption compared to the both-freeze condition.

}Sharing and watching live 360 panorama video is available on modern social networking platforms, yet the communication is often a passive one-directional experience. This research investigates how to further improve live 360 panorama based remote collaborative experiences by adding Mixed Reality (MR) cues. SharedSphere is a wearable MR remote collaboration system that enriches a live captured immersive panorama based collaboration through MR visualisation of non-verbal communication cues (e.g., view awareness and gestures cues). We describe the design and implementation details of the prototype system, and report on a user study investigating how MR live panorama sharing affects the user's collaborative experience. The results showed that providing view independence through sharing live panorama enhances co-presence in collaboration, and the MR cues help users understanding each other. Based on the study results we discuss design implications and future research direction.

}Collaboration is an important application area for virtual reality (VR). However, unlike in the real world, collaboration in VR misses important empathetic cues that can make collaborators aware of each other's emotional states. Providing physiological feedback, such as heart rate or respiration rate, to users in VR has been shown to create a positive impact in single user environments. In this paper, through a rigorous mixed-factorial user experiment, we evaluated how providing heart rate feedback to collaborators influences their collaboration in three different environments requiring different kinds of collaboration. We have found that when provided with real-time heart rate feedback participants felt the presence of the collaborator more and felt that they understood their collaborator's emotional state more. Heart rate feedback also made participants feel more dominant when performing the task. We discuss the implication of this research for collaborative VR environments, provide design guidelines, and directions for future research.

}In this poster, we explore the social sharing of surrounding environments on wearable Augmented Reality (AR) devices. In particular, we propose filtering the level of detail of sharing the surrounding environment based on the social proximity between the viewer and the sharer. We test the effect of having the filter (varying levels of detail) on the shared surrounding environment on the sense of privacy from both viewer and sharer perspectives and conducted a pilot study using HoloLens. We report on semi-structured questionnaire results and suggest future directions in the social sharing of surrounding environments.

}In this paper, we explore how Augmented Reality (AR) and anthropomorphism can be used to assign emotions to common physical objects based on their needs. We developed a novel emotional interaction model among personified physical objects so that they could react to other objects by changing virtual facial expressions. To explore the effect of such an emotional interface, we conducted a user study comparing three types of virtual cues shown on the real objects: (1) information only, (2) emotion only and (3) both information and emotional cues. A significant difference was found in task completion time and the quality of work when adding emotional cues to an informational AR-based guiding system. This implies that adding emotion feedback to informational cues may produce better task results than using informational cues alone.

}The Mixed Reality (MR) technology can be used to create unique collaborative experiences. In this paper, we propose a new remote collaboration platform using MR and eye-tracking that enables a remote helper to assist a local worker in an assembly task. We present results from research exploring the effect of sharing virtual gaze and annotations cues in an MR-based projector interface for remote collaboration. The key advantage compared to other remote collaborative MR interfaces is that it projects the remote expert's eye gaze into the real worksite to improve co-presence. The prototype system was evaluated with a pilot study comparing two conditions: POINTER and ET (eye-tracker cues). We observed that the task completion performance was better in the ET condition. And that sharing gaze significantly improved the awareness of each other's focus and co-presence.

}This research investigates using user interface (UI) agents for guiding gesture based interaction with Augmented Virtual Mirrors. Compared to prior work in gesture interaction, where graphical symbols are used for guiding user interaction, we propose using UI agents. We explore two approaches for using UI agents: 1) using a UI agent as a delayed cursor and 2) using a UI agent as an interactive button. We conducted two user studies to evaluate the proposed designs. The results from the user studies show that UI agents are effective for guiding user interactions in a similar way as a traditional graphical user interface providing visual cues, while they are useful in emotionally engaging with users.

}To improve remote collaboration in video conferencing systems, researchers have been investigating augmenting visual cues onto a shared live video stream. In such systems, a person wearing a head-mounted display (HMD) and camera can share her view of the surrounding real-world with a remote collaborator to receive assistance on a real-world task. While this concept of augmented video conferencing (AVC) has been actively investigated, there has been little research on how sharing gaze cues might affect the collaboration in video conferencing. This paper investigates how sharing gaze in both directions between a local worker and remote helper in an AVC system affects the collaboration and communication. Using a prototype AVC system that shares the eye gaze of both users, we conducted a user study that compares four conditions with different combinations of eye gaze sharing between the two users. The results showed that sharing each other’s gaze significantly improved collaboration and communication.

month={March},}Eye tracking technology in a head-mounted display has undergone rapid advancement in recent years, making it possible for researchers to explore new interaction techniques using natural eye movements. This paper explores three novel eye-gaze-based interaction techniques: (1) Duo-Reticles, eye-gaze selection based on eye-gaze and inertial reticles, (2) Radial Pursuit, cluttered-object selection that takes advantage of smooth pursuit, and (3) Nod and Roll, head-gesture-based interaction based on the vestibulo-ocular reflex. In an initial user study, we compare each technique against a baseline condition in a scenario that demonstrates its strengths and weaknesses.

}Game balancing can be used to compensate for differences in players' skills, in particular in games where players compete against each other. It can help providing the right level of challenge and hence enhance engagement. However, there is a lack of understanding of game balancing design and how different game adjustments affect player engagement. This understanding is important for the design of balanced physical games. In this paper we report on how altering the game equipment in a digitally augmented table tennis game, such as the table size and bat-head size statically and dynamically, can affect game balancing and player engagement. We found these adjustments enhanced player engagement compared to the no-adjustment condition. The understanding of how the adjustments impacted on player engagement helped us to derive a set of balancing strategies to facilitate engaging game experiences. We hope that this understanding can contribute to improve physical activity experiences and encourage people to get engaged in physical activity.

}Interfaces for collaborative tasks, such as multiplayer games can enable more effective and enjoyable collaboration. However, in these systems, the emotional states of the users are often not communicated properly due to their remoteness from one another. In this paper, we investigate the effects of showing emotional states of one collaborator to the other during an immersive Virtual Reality (VR) gameplay experience. We created two collaborative immersive VR games that display the real-time heart-rate of one player to the other. The two different games elicited different emotions, one joyous and the other scary. We tested the effects of visualizing heart-rate feedback in comparison with conditions where such a feedback was absent. The games had significant main effects on the overall emotional experience.

}Driving a car is a high cognitive-load task requiring full attention behind the wheel. Intelligent navigation, transportation, and in-vehicle interfaces have introduced a safer and less demanding driving experience. However, there is still a gap for the existing interaction systems to satisfy the requirements of actual user experience. Hand gesture as an interaction medium, is natural and less visually demanding while driving. This paper aims to conduct a user-study with 79 participants to validate mid-air gestures for 18 major in-vehicle secondary tasks. We have demonstrated a detailed analysis on 900 mid-air gestures investigating preferences of gestures for in-vehicle tasks, their physical affordance, and driving errors. The outcomes demonstrate that employment of mid-air gestures reduces driving errors by up to 50% compared to traditional air-conditioning control. Results can be used for the development of vision-based in-vehicle gestural interfaces.

}Percutaneous radiology procedures often require the repeated use of medical radiation in the form of computed tomography (CT) scanning, to demonstrate the position of the needle in the underlying tissues. The angle of the insertion and the distance travelled by the needle inside the patient play a major role in successful procedures, and must be estimated by the practitioner and confirmed periodically by the use of the scanner. Junior radiology trainees, who are already highly trained professionals, currently learn this task “on-the-job” by performing the procedures on real patients with varying levels of guidance. Therefore, we present a novel Augmented Reality (AR)-based system that provides multiple layers of intuitive and adaptive feedback to assist junior radiologists in achieving competency in image-guided procedures.

}In this chapter, an overview of using AR for gaming and entertainment is provided, one of the most popular application areas. There are many possible AR entertainment applications. For example, the Pokémon Go mobile phone game has an AR element that allows people to see virtual Pokémon to appear in the live camera view, seemingly inhabiting the real world. In this case, Pokémon Go satisfies Azuma’s three AR criteria: the virtual Pokémon appears in the real world, the user can interact with them, and they appear fixed in space.

}In this paper we describe a new method for determining gaze depth in a head mounted eye-tracker. Eyetrackers are being incorporated into head mounted displays (HMDs), and eye-gaze is being used for interaction in Virtual and Augmented Reality. For some interaction methods, it is important to accurately measure the x- and y-direction of the eye-gaze and especially the focal depth information. Generally, eye tracking technology has a high accuracy in x- and y-directions, but not in depth. We used a binocular gaze tracker with two eye cameras, and the gaze vector was input to an MLP neural network for training and estimation. For the performance evaluation, data was obtained from 13 people gazing at fixed points at distances from 1m to 5m. The gaze classification into fixed distances produced an average classification error of nearly 10%, and an average error distance of 0.42m. This is sufficient for some Augmented Reality applications, but more research is needed to provide an estimate of a user’s gaze moving in continuous space.

}Empathic Computing is a research field that aims to use technology to create deeper shared understanding or empathy between people. At the same time, Mixed Reality (MR) technology provides an immersive experience that can make an ideal interface for collaboration. In this paper, we present some of our research into how MR technology can be applied to creating Empathic Computing experiences. This includes exploring how to share gaze in a remote collaboration between Augmented Reality (AR) and Virtual Reality (VR) environments, using physiological signals to enhance collaborative VR, and supporting interaction through eye-gaze in VR. Early outcomes indicate that as we design collaborative interfaces to enhance empathy between people, this could also benefit the personal experience of the individual interacting with the interface.

}In this poster, we describe The Social AR Continuum, a space that encompasses different dimensions of Augmented Reality (AR) for sharing social experiences. We explore various dimensions, discuss options for each dimension, and brainstorm possible scenarios where these options might be useful. We describe a prototype interface using the contact placement dimension, and report on feedback from potential users which supports its usefulness for visualising social contacts. Based on this concept work, we suggest user studies in the social AR space, and give insights into future directions.

}Augmenting video conference with additional visual cues has been studied to improve remote collaboration. A common setup is a person wearing a head-mounted display (HMD) and camera sharing her view of the workspace with a remote collaborator and getting assistance on a real-world task. While this configuration has been extensively studied, there has been little research on how sharing gaze cues might affect the collaboration. This research investigates how sharing gaze in both directions between a local worker and remote helper affects the collaboration and communication. We developed a prototype system that shares the eye gaze of both users, and conducted a user study. Preliminary results showed that sharing gaze significantly improves the awareness of each other's focus, hence improving collaboration.

}We present CoVAR, a novel Virtual Reality (VR) and Augmented Reality (AR) system for remote collaboration. It supports collaboration between AR and VR users by sharing a 3D reconstruction of the AR user's environment. To enhance this mixed platform collaboration, it provides natural inputs such as eye-gaze and hand gestures, remote embodiment through avatar's head and hands, and awareness cues of field-of-view and gaze cue. In this paper, we describe the system architecture, setup and calibration procedures, input methods and interaction, and collaboration enhancement features.

}This demonstration presents a development of an Augmented Reality (AR) and Virtual Reality (AR) pillar, a novel approach for showing AR and VR content in a public setting. A pillar in a public exhibition venue was converted to a four-sided AR and VR showcase. A cultural heritage theme of Boatbuilders of Pangkor was been featured in an experiment of the AR and VR Pillar. Multimedia tablets and mobile AR head-mount-displays (HMDs) were freely provided for the public visitors to experience multisensory content demonstrated on the pillar. The content included AR-based videos, maps, images and text, and VR experiences that allowed visitors to view reconstructed 3D subjects and remote locations in a 360 virtual environment. A miniature version of the pillar will be used for the demonstration where users could experience features of the prototype system.

}View: https://ir.canterbury.ac.nz/bitstream/handle/10092/15215/icat-egve2017-HumayunKhan.pdf?sequence=2Head-mounted displays are becoming increasingly popular as home entertainment devices for viewing 360◦ movies. This paper explores the effects of adding gesture interaction with virtual content and two different hand-visualisation modes for 360◦ movie watching experience. The system in the study comprises of a Leap Motion sensor to track the user’s hand and finger motions, in combination with a SoftKinetic RGB-D camera to capture the texture of the hands and arms. A 360◦ panoramic movie with embedded virtual objects was used as content. Four conditions, displaying either a point-cloud of the real hand or a rigged computer-generated hand, with and without interaction, were evaluated. Presence, agency, embodiment, and ownership, as well as the overall participant preference were measured. Results showed that participants had a strong preference for the conditions with interactive virtual content, and they felt stronger embodiment and ownership. The comparison of the two hand visualisations showed that the display of the real hand elicited stronger ownership. There was no overall difference for presence between the four conditions. These findings suggest that adding interaction with virtual content could be beneficial to the overall user experience, and that interaction should be performed using the real hand visualisation instead of the virtual hand if higher ownership is desired.

There are previous research on user embodiment in real-time rendered VR, but not in relation to cinematic VR based on 360 panoramic video. In this paper we explore the effects of introducing the user’s real body into cinematic VR experiences. We conducted a study evaluating how the type of movie and user embodiment affects the sense of presence and user engagement. We found that when participants were able to see their own body in the VR movie, there was significant increase in the sense of Presence, yet user engagement was not significantly affected. We discuss on the implications of the results and how it can be expanded in the future.

}The rapid developement of machine learning algorithms can be leveraged for potential software solutions in many domains including techniques for depth estimation of human eye gaze. In this paper, we propose an implicit and continuous data acquisition method for 3D gaze depth estimation for an optical see-Through head mounted display (OST-HMD) equipped with an eye tracker. Our method constantly monitoring and generating user gaze data for training our machine learning algorithm. The gaze data acquired through the eye-tracker include the inter-pupillary distance (IPD) and the gaze distance to the real andvirtual target for each eye.

}Previous investigations have shown that pupil dilation can be affected by emotive pictures, audio clips, and videos. In this paper, we explore how emotive Virtual Reality (VR) content can also cause pupil dilation. VR has been shown to be able to evoke negative and positive arousal in users when they are immersed in different virtual scenes. In our research, VR scenes were used as emotional triggers. Five emotional VR scenes were designed in our study and each scene had five emotion segments; happiness, fear, anxiety, sadness, and disgust. When participants experienced the VR scenes, their pupil dilation and the brightness in the headset were captured. We found that both the negative and positive emotion segments produced pupil dilation in the VR environments. We also explored the effect of showing heart beat cues to the users, and if this could cause difference in pupil dilation. In our study, three different heart beat cues were shown to users using a combination of three channels; haptic, audio, and visual. The results showed that the haptic-visual cue caused the most significant pupil dilation change from the baseline.

}This paper explores the effects of different collaborative view configuration on face-to-face collaboration using a wall-size display and the relationship between view configuration and multi-user interaction. Three different view configurations (shared view, split screen, and split screen with navigation information) for multi-user collaboration with a wall-size display were introduced and evaluated in a user study. From the experiment results, several insights for designing a virtual environment with a wall-size display were discussed. The shared view configuration does not disturb collaboration despite control conflict and can provide an effective collaboration. The split screen view configuration can provide independent collaboration while it can take users’ attention. The navigation information can reduce the interaction required for the navigational task while an overall interaction performance may not increase.

}A mid-air gesture-based interface could provide a less cumbersome in-vehicle interface for a safer driving experience. Despite the recent developments in gesture-driven technologies facilitating the multi-touch and mid-air gestures, interface safety requirements as well as an evaluation of gesture characteristics and functions, need to be explored. This paper describes an optimization study on the previously developed GestDrive gesture vocabulary for in-vehicle secondary tasks. We investigate mid-air gestures and secondary tasks, their correlation, confusions, unintentional inputs and consequential safety risks. Building upon a statistical analysis, the results provide an optimized taxonomy break-down for a user-centered gestural interface design which considers user preferences, requirements, performance, and safety issues.

}We present a multi-scale gestural interface for augmented reality applications. With virtual objects, gestural interactions such as pointing and grasping can be convenient and intuitive, however they are imprecise, socially awkward, and susceptible to fatigue. Our prototype application uses multiple sensors to detect gestures from both arm and hand motions (macro-scale), and finger gestures (micro-scale). Micro-gestures can provide precise input through a belt-worn sensor configuration, with the hand in a relaxed posture. We present an application that combines direct manipulation with microgestures for precise interaction, beyond the capabilities of direct manipulation alone.

}We present a Mixed Reality (MR) system that supports entire scene capturing of the local physical work environment for remote collaboration in a large-scale workspace. By integrating the key-frames captured with external depth sensor as one single 3D point-cloud data set, our system could reconstruct the entire local physical workspace into the VR world. In this case, the remote helper could observe the local scene independently from the local user's current head and camera position, and provide gesture guiding information even before the local user staring at the target object. We conducted a pilot study to evaluate the usability of the system by comparing it with our previous oriented view system which only sharing the current camera view together with the real-time head orientation data. Our results indicate that this entire scene capturing and sharing system could significantly increase the remote helper's spatial awareness of the local work environment, especially in a large-scale workspace, and gain an overwhelming user preference (80%) than previous system.

}In this research we present a calibration method that enables 6 degree of freedom (DoF) interaction technology with high accuracy for the Microsoft HoloLens using HTC Vive controllers. We calibrate the HoloLens's front color camera with the Vive lighthouse sensors by tracking a reference image and a Vive tracker at the first beginning automatically, and the Vive controllers' position and pose data can be transmitted to the HoloLens in real time via the Bluetooth connection, which provides a more accurate and efficient input solution for users to manipulate the augmented content compared with the default gesture or head-gaze interfaces.

We created CoVAR, a MR system for remote collaboration between an Augmented Reality (AR) and Augmented Virtuality (AV) users. Awareness cues and AV-Snap-to-AR interface were proposed for enhancing communication. Collaborative natural interaction, and AV-User-Body-Scaling were implemented for enhancing interaction. We conducted an exploratory study examining the awareness cues and the collaborative gaze, and the results showed the benefits of the proposed techniques for enhancing communication and interaction.

}One of the key problems with representing social networks in Augmented Reality (AR) is how to differentiate between contacts. In this paper we explore how visual and spatial cues based on social relationships can be used to represent contacts in social AR applications, making it easier to distinguish between them. Previous implementations of social AR have been mostly focusing on location based visualization with no focus on the social relationship to the user. In contrast, we explore how to visualise social relationships in mobile AR environments using proximity and visual fidelity filters. We ran a focus group to explore different options for representing social contacts in a mobile an AR application. We also conducted a user study to test a head-worn AR prototype using proximity and visual fidelity filters. We found out that filtering social contacts on wearable AR is preferred and useful. We discuss the results of focus group and the user study, and provide insights into directions for future work.

month={Nov},}We present results from research exploring the effect of sharing virtual gaze and pointing cues in a wearable interface for remote collaboration. A local worker wears a Head-mounted Camera, Eye-tracking camera and a Head-Mounted Display and shares video and virtual gaze information with a remote helper. The remote helper can provide feedback using a virtual pointer on the live video view. The prototype system was evaluated with a formal user study. Comparing four conditions, (1) NONE (no cue), (2) POINTER, (3) EYE-TRACKER and (4) BOTH (both pointer and eye-tracker cues), we observed that the task completion performance was best in the BOTH condition with a significant difference of POINTER and EYETRACKER individually. The use of eye-tracking and a pointer also significantly improved the co-presence felt between the users. We discuss the implications of this research and the limitations of the developed system that could be improved in further work.

Using our system, a local worker can share a view of their environment with a remote helper, as well as their gaze, facial expressions, and physiological signals. The remote user can send back visual cues via a see-through head mounted display to help them perform better on a real world task. The system also provides some indication of the remote users face expression using face tracking technology.

In this paper, we describe Empathy Glasses, a head worn prototype designed to create an empathic connection between remote collaborators. The main novelty of our system is that it is the first to combine the following technologies together: (1) wearable facial expression capture hardware, (2) eye tracking, (3) a head worn camera, and (4) a see-through head mounted display, with a focus on remote collaboration. Using the system, a local user can send their information and a view of their environment to a remote helper who can send back visual cues on the local user's see-through display to help them perform a real world task. A pilot user study was conducted to explore how effective the Empathy Glasses were at supporting remote collaboration. We describe the implications that can be drawn from this user study.

}In this paper we report on a user study in a simulated environment that compares three types of Augmented Reality (AR) displays for assisting with car navigation: Heads Up Display (HUD), Head Mounted Display (HMD) and Heads Down Display (HDD). The virtual cues shown on each of the interface were the same, but there was a significant difference in driver behaviour and preference between interfaces. Overall, users performed better and preferred the HUD over the HDD, and the HMD was ranked lowest. These results have implications for people wanting to use AR cues for car navigation.

}Augmented Reality (AR) interfaces have been studied extensively over the last few decades, with a growing number of user-based experiments. In this paper, we systematically review most AR papers published between 2005 and 2014 that include user studies. A total of 291 papers have been reviewed and classified based on their application areas. The primary contribution of the review is to present the broad landscape of user-based AR research, and to provide a high-level view of how that landscape has changed. We also identify areas where there have been few user studies, and opportunities for future research. This poster describes the methodology of the review and the classifications of AR research that have emerged.

}This paper explores different visual interfaces for sharing comments on a social live video streaming platforms. So far, comments are displayed separately from the video making it hard to relate the comments to event in the video. In this work we investigate an Augmented Reality (AR) interface displaying comments directly on the streamed live video. Our described prototype allows remote spectators to perceive the streamed live video with different interfaces for displaying the comments. We conducted a user study to compare different ways of visualising comments and found that users prefer having comments in the AR view rather than on a separate list. We discuss the implications of this research and directions for future work.

}View: https://www.bartneck.de/publications/2016/digitallyAugmentingSports/altimiraBartneckCHI2016.pdfUsing game balancing techniques can provide the right level of challenge and hence enhance player engagement for sport players with different skill levels. Digital technology can support and enhance balancing techniques in sports, for example, by adjusting players’ level of intensity based on their heart rate. However, there is limited knowledge on how to design such balancing and its impact on the user experience. To address this we created two novel balancing techniques enabled by digitally augmenting a table tennis table. We adjusted the more skilled player’s performance by inducing two different styles of play and studied the effects on game balancing and player engagement. We showed that by altering the more skilled player’s performance we can balance the game through: (i) encouraging game mistakes, and (ii) changing the style of play to one that is easier for the opponent to counteract. We outline the advantages and disadvantages of each approach, extending our understanding of game balancing design. We also show that digitally augmenting sports offers opportunities for novel balancing techniques while facilitating engaging experiences, guiding those interested in HCI and sports.

}We present a Mixed Reality system for remote collaboration using Virtual Reality (VR) headsets with external depth cameras attached. By wirelessly sharing a 3D point-cloud data of a local workers' workspace with a remote helper, and sharing the remote helper's hand gestures back to the local worker, the remote helper is able to assist the worker to perform manual tasks.Displaying the point-cloud video in a conventional way, such as a static front view in VR headsets, does not provide helpers with sufficient understanding of the spatial relationships between their hands and the remote surroundings. In contrast, we propose a Mixed Reality (MR) system that shares with the remote helper, not only 3D captured environment data but also real-time orientation info of the worker's viewpoint. We conducted a pilot study to evaluate the usability of the system, and we found that extra synchronized orientation data can make collaborators feel more connected spatially and mentally.- 2015

}Augmented Reality (AR) on smart phones can be used to overlay virtual tags in the real world to show points of interest that people may want to visit. However, field tests have failed to validate the belief that AR-based tools would outperform map-based tools for such pedestrian navigation tasks. Assuming this is due to inaccuracies in consumer GPS tracking used in handheld AR, we created a simulated environment that provided perfect tracking for AR and conducted experiments based on real world navigation studies. We measured time-on-task performance for guided traversals on both desktop and head-mounted display systems and found that accurate tracking did validate the superior performance of AR-based navigation tools. We also measured performance for unguided recall traversals of previously traversed paths in order to investigate into how navigation tools impact upon route memory.

While the stereoscopic visualization is widely adopted in immersive visualization systems to improve user experience, it can also cause visual discomfort if the stereoscopic viewing parameters are not adjusted appropriately. These parameters are usually manually adjusted based on human factors and empirical knowledge of the developer or even the user. However, scenes with dynamic change in scale and configuration can lead into continuous adjustment of these parameters while viewing. In this paper, we propose a method to adjust the interpupillary distance adaptively and automatically according to the configuration of the 3D scene, so that the visualized scene can maintain sufficient stereo effect while reducing visual discomfort.

}We investigate the combination of Augmented Reality (AR) with Intelligent Tutoring Systems (ITS) to assist with training for manual assembly tasks. Our approach combines AR graphics with adaptive guidance from the ITS to provide a more effective learning experience. We have developed a modular software framework for intelligent AR training systems, and a prototype based on this framework that teaches novice users how to assemble a computer motherboard. An evaluation found that our intelligent AR system improved test scores by 25 % and that task performance was 30 % faster compared to the same AR training system without intelligent support. We conclude that using an intelligent AR tutor can significantly improve learning compared to more traditional AR training.

}Public information displays are evolving from passive screens into more interactive and smarter ubiquitous computing platforms. In this research we investigate applying gesture interaction and Augmented Reality (AR) technologies to make public information displays more intuitive and easy to use. We focus especially on designing intuitive gesture based interaction methods to use in combination with an augmented virtual mirror interface. As an initial step, we conducted a user study to indentify the gestures that users feel are natural for performing common tasks when interacting with augmented virtual mirror displays. We report initial findings from the study, discuss design guidelines, and suggest future research directions.

}Drawing annotations on shared live video has been investigated as a tool for remote collaboration. However, if a local user changes the viewpoint of a shared live video while a remote user is drawing an annotation, the annotation is projected and drawn at wrong place. Prior work suggested manually freezing the video while annotating to solve the issue, but this needs additional user input. We introduce a solution that automatically freezes the video, and present the results of a user study comparing it with manual freeze and no freeze conditions. Auto-freeze was most preferred by both remote and local participants who felt it best solved the issue of annotations appearing in the wrong place. With auto-freeze, remote users were able to draw annotations quicker, while the local users were able to understand the annotations clearer.haptic HONGI: Reflections on collaboration in the transdisciplinary creation of an AR artwork in Creating Digitally
