Turning your video monitor into a virtual window
Jeremy R. Cooperstock, Koichiro Tanikoshi, William A. S. Buxton · 2002
A video conference system that allows a video attendee to look around an entire conference room simply by moving his or her head is described. In order to locate the attendee's head, a differential image is produced by removing a reference view from the current video image. The orientation of a motorized camera is then determined directly by the head position of the video attendee. The increased affordances of this mechanism are discussed.
