MPConnect: A Mixed Presence Mixed Reality System

This project explores how a Mixed Presence Mixed Reality System can enhance remote collaboration. Collaborative Mixed Reality (MR) is a popular area of research, but most work has focused on one-to-one systems where either both collaborators are co-located or the collaborators are remote from one another. For example, remote users might collaborate in a shared Virtual Reality (VR) system, or a local worker might use an Augmented Reality (AR) display to connect with a remote expert to help them complete a task.

However, most conferencing software requires groups of both remote and co-located collaborators to work together using different platforms. For example a group of people might connect over video conferencing from their laptop or desktop computers or mobile phones and tablets. Some of them might be face to face in the same room, while others are remote. So Mixed Presence (MP) collaborations involve both locally present (co-located) and remote collaborators. However, most Mixed Presence research has so far focused on table-top based collaborations, where people sitting around a real table might connect with one or more remote collaborators on a video conferencing link.

This research aims to bring together Mixed Reality research and Mixed Presence research to pave the way forward for future MR based groupware. So it explores how face to face users with Augmented Reality (AR) head mounted displays can collaborate with remote users on a desktop system. The current prototype has two users in Microsoft Hololens displays viewing and interacting with AR content on a table between them, while a third remote user on a desktop computer provides guidance. This research both reassesses techniques developed for one-to-one MR collaborative systems in context of Mixed Presence and develops new methods for MP MR collaborative systems.

    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.
