Abstract: An eye tracking system includes a pair of glasses including two frames, a projector coupled to the pair of glasses and operable to project a beam of light, and an eyepiece mounted in one of the two frames and optically coupled to the projector. The eyepiece is operable to direct at least a portion of the beam of light towards an eye of a user. The eye tracking system also includes one or more optical sensors coupled to at least one of the two frames of the pair of glasses and operable to detect a set of reflected signals off the eye of the user, and a processor coupled to the projector and the one or more optical sensors, wherein the processor is operable to determine an eye orientation based on the set of reflected signals.
