Extended Reality (XR) opens up new possibilities for education, manufacturing and cultural heritage. Social XR takes a step further by making these virtual experiences shared. No longer just watching, people meet in the same virtual world, as avatars or volumetric captures of themselves, to communicate and collaborate in real time, even when physically apart.

Creating these virtual worlds requires solving interconnected challenges across the entire Social XR pipeline. We need to understand and model how people behave and relate within them, design intuitive spatial interactions and engineer networks that keep remote experiences seamless and real-time. At the same time, we must ensure these systems are ethical, private, accessible and safe for everyone who uses them. Addressing these challenges demands a deep synergy between computer graphics, networking and systems, signal processing, multimedia, interaction design and the social sciences.
