Adventures in the Realverse: Experiences and Challenges in XR Communications

Extended Reality is called to change human communications, in the same way that the telephone or the video call did. We are still at the beginning of the road, but the technology is already advanced and affordable enough to give us a glimpse of what XR communications will look like. What technological modules are needed to build an XR system that allows you to "teleport" to another location? Is it available to anyone, is it inclusive? What networks and telecommunication systems are needed to make it work? How can we model the Quality of Experience? In this talk we will raise these and other questions and try to outline some answers.
