Abstract
Described herein is a telepresence system where a real-time a virtual hologram of a user is displayed at a remote display screen and is rendered from a vantage point that is different than the vantage point from which images of the user are captured via a video camera. The virtual hologram is based at least in part upon data acquired from a sensor unit at the location of the user. The sensor unit includes a color video camera that captures 2-D images of the user including surface features of the user. The sensor unit also includes a depth sensor that captures 3-D geometry data indicative of the relative position of surfaces on the user in 3-D space. The virtual hologram is rendered to orientate the gaze of the eyes of the virtual hologram towards the eyes of a second user viewing the remote display screen.
