Extended Reality (XR) is an upcoming field of technology that has garnered interest from researchers in the last few decades. This increased interest is largely due to the development of powerful hardware like the Microsoft HoloLens, Oculus Quest and the Magic Leap. Several companies like Microsoft, Meta Platforms, Apple and Nvidia are touting the rise of a new "metaverse'' - the next generation of the internet, that will blur the lines between physical and virtual presence. This thesis explores the use of web-based XR platforms in Computer-Supported Cooperative Work (CSCW) as an alternative to contemporary video conferencing tools.
We conducted a user study with 15 subjects to evaluate web-based XR platforms (Mozilla Hubs) with video conferencing (Zoom) and examined subject attention and success in remote collaborative tasks. We also proposed a new system design to support embodied interactions in XR. This system was tested by measuring the communication latency between two collaborators separated by varying distances. Our system performance evaluation suggests the feasibility of support embodied interactions, with a minimal latency of 120ms across a distance of 4700 miles. / Master of Science / Extended Reality (XR) is changing the way we interact with digital content. In 2021, several companies like Microsoft, Meta Platforms, Apple and Nvidia are developing devices that allow users to physically interact with virtual content in 3-dimensional space. These technologies bring with them the promise of better remote communication and collaboration. Users will be able to enter these 3d virtual spaces as avatars and will be able to interact with digital media just like they would with real world objects. This thesis explores the use of web-based XR platforms in supporting remote collaboration as an alternative to contemporary video conferencing tools.
We conducted a user study with 15 subjects to compare differences in web-based XR platforms (Mozilla Hubs) with video conferencing (Zoom). We proposed and evaluated a new system design to support more natural and intuitive interactions in XR. This system was tested by measuring the communication latency between two collaborators separated by varying distances. Our system performance evaluation suggests the feasibility of support embodied interactions, with a minimal latency of 120ms across a distance of 4700 miles.
