HTC has demonstrated a feature expected in SteamVR 2.0: tracking of a virtual reality space across rooms.
Current room-scale VR with an HTC Vive is designed for a simple area with a diagonal of up to 5m. HTC Vive President Alvin Wang Graylin posted a video on Twitter showing what we can expect from the next generation of VR sensor software.
