Abstract
A method of tracking an eye gaze include obtaining a pre-calibrated speckle map of the eye of the user, determining a starting position of the eye using the pre-calibrated speckle map, and tracking movement of the eye relative to the starting position by: directing a light beam at the eye, detecting a plurality of speckle patterns formed at a detector by a portion of the light beam reflected by the eye, and tracking movement of the eye relative to the starting position by tracking the plurality of speckle patterns from frame to frame.
