Abstract
Systems, devices, and methods for tracking eye movement and gaze direction using infrared light are described. The method includes projecting infrared light from at least one pixel in the display screen to the eye of the user, detecting a plurality of reflections of the infrared light from the eye, determining the relative intensity of each of the plurality of the reflections, identifying, from the plurality of reflections, a region of the eye that corresponds to a relatively low intensity reflection, and determining a position of the eye based on the region of the eye that corresponds to the relatively low intensity reflection.
