Abstract
A method, computer readable medium, and system are disclosed for gaze tracking. The method includes the steps of receiving reflected light rays at an optical sensor, where all of the reflected light rays converge towards a rotational center of an eye and generating pattern data based on intersections of the reflected light rays at a surface of the optical sensor. A processor computes an estimated gaze direction of the eye based on the pattern data.
