Social VR

A New Medium for Remote Communication & Collaboration

CHI 2021 Workshop
May 07, 3:00 PM GMT+2
Online: Mozilla Hubs

Important Dates

Submission Deadline: February 21, 2021

Notification: February 28, 2021

This is the 2nd CHI Social VR workshop. It is intended for continuing interdisciplinary discussions regarding proxemics, social cues, and virtual environment designs, which were identified as three important aspects of Social VR communication in our CHI 2020 Social VR Workshop.


This workshop is supported by Mozilla Hubs, and sponsored by the European Commission H2020 program, project "VRTogether".

Remote communication allows people who are not physically present in the same location to communicate with each other in real-time. This permits us to meet colleagues overseas, work from home to reduce commute costs, and live far from our friends and families.


Social Virtual Reality (VR) invites multiple users to join a collaborative virtual environment (VE), which creates new opportunities for remote communication. The shared experiences obtained in social VR may reshape our subjective perception towards the physical world, leading to shifts in our understanding about social experiences, personal spaces, or realness of the VE, and bringing about novel everyday social interactions. However, social VR also raises privacy concerns and ethical risks when the boundary between the real and the virtual world is blurred. In this workshop, we intend to spur discussions on social VR as an emerging immersive remote communication tool.

The exciting news is that this social VR themed workshop will be held virtually on a social VR platform called Mozilla Hubs. We would like to invite academics from all fields, e.g., computer science, psychology, HCI/UX, sociology, and designers, developers, practitioners, governmental policymakers to gather together on a social VR platform and to envision a future research agenda for social VR in terms of proxemics, social cues, and VE designs.

This virtual workshop invites submission of position papers: 2-4 pages in SIGCHI Extend Abstract format (reference excluded), covering but not limited to the following topics:

  • Personal Space in Social VR. How interpersonal distance is perceived in social VR when people can move in VEs beyond reality (e.g., flying)? What may be the differences in users’ personal space perception when they using a desktop compared to wearing an HMD? What is the ideal interpersonal distance in VR collaboration?

  • Social Cues. What are the missing social cues in existing social VR platforms? How do users start a conversation in a VE? What are the most necessary social cues to ensure natural and immersive collaboration, eye contacts, hand gestures, head movements?

  • VE Designs. How to design the VEs to better facilitate virtual collaboration? How to design the VEs to prevent harmful virtual behavior? How to design VEs to ensure that it is aesthetically appealing and functionally sound (not distracting, and helping users focus on the virtual tasks)?

  • Social VR Technologies. What is the current status of technology (e.g. capturing, reconstruction, rendering)? What are the technological requirements for improving social VR experiences in terms of quality of interaction, privacy protection etc.?

  • Evaluation Protocols for Social VR Experiences. How to adequately evaluate different aspects of commu- nication in social VR both subjectively (e.g., self-reports) and objectively (e.g., physiological sensors)? How to develop Quality of Experience (QoE) metrics for social VR?

  • Interaction Techniques for SocialVR. Should the interaction techniques replicate the real-world ones through the aid of multi-sensory simulation? Or should the interaction techniques extend beyond reality?

Submitted position papers will be reviewed and selected by the workshop organizers. At least one author of the accepted paper must attend the workshop. All participants must register for both the workshop and for at least one day of the conference.
