Abstract: Aspects of the embodiments are directed to systems, methods, and devices for eye gaze tracking. In embodiments, a projective surface, such as a virtual reality display screen or augmented reality projective surface, can project light towards a wearer's eyes. The light can be light representing the shape of the projective surface or can be a displayed shape. The light can be reflected from a cornea. The reflected light from the cornea can be received. A distortion of the shape of the projective surface or displayed shape can be used to determine an eye gaze position.
