The Shared Reality Project investigates remote collaboration ecosystems that are spatial, immersive and widely accessible. The DualStream augmented reality prototype enables users to spatially share information about themselves and their surroundings in real time. Going beyond traditional audio and video conferencing tools, DualStream can convey three-dimensional information about facial expressions, creating avatars that look and move as we do in real life. Leveraging the mobility and ubiquity of phones, DualStream enables users to simultaneously feel they are “being there” in a remote location, and remote participants are “being here” in their local environment. DualStream envisions spatial computing that is more widely accessible than experiences reliant on expensive head-worn devices. By building cross-reality ecosystems with stronger connections across mobile devices, PCs and immersive setups, we can better support collaboration between people no matter where they are located or what tools they have access to.
