Abstract:
A system of eye tracking includes an infrared (IR) source to project IR light to an eye of a user, an IR holographic optical element (HOE) to change an angle of the IR light reflected from the eye of the user, and a sensor to receive the IR light. The system further includes a processor to use the IR light to determine a gaze vector of the user, in one embodiment.
