Abstract:
A gaze-tracking system for use in a head-mounted display apparatus. The gaze-tracking system includes at least one illuminator for emitting light pulses; at least one first optical element comprising a plurality of micro-to-nano-sized components, shaped and arranged relative to each other in a manner that, when incident thereupon, a structure of the light pulses is modified to produce structured light, wherein the produced structured light is used to illuminate a user's eye; at least one camera for capturing an image of reflections of the structured light from the user's eye, wherein the image is representative of a form and a position of the reflections on an image plane of the at least one camera; and a processor configured to control the at least one illuminator and the at least one camera, and to process the captured image to detect a gaze direction of the user.

Claim (Index 9):
The gaze-tracking system of  claim 1 , further comprising at least one light guide for guiding the light pulses emitting from the at least one illuminator towards the at least one first optical element.
