Abstract
Abstract An eye tracking system is disclosed which is comprised of an eye tracking module formed of a display joined to a photodetector array. Each pixel in the display is aligned with a corresponding photodetector. An image generated by the display is projected onto a viewing screen or toward a viewer. Axial light rays from the display pixels are reflected by the eye and detected by a respective photodetector which generates an electrical signal indicative of eye position.
