Abstract:

A head position and orientation sensor system utilizes a head-mounted projector of known scan pattern which presents a visual display to the observer. In order to maintain proper display orientation, the head position and orientation are measured by intercepting the projected light scan pattern at a retroreflective screen upon which the visual display is focused. A photodetector array mounted in said screen intercepts the visual display regardless of head orientation and position. A computational unit having knowledge of the scan pattern parameters correlates the photodetector array output to a unique head position and orientation. Author
