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 1):
A gaze-tracking system for use in a head-mounted display apparatus, the gaze-tracking system comprising:\n at least one illuminator for emitting light pulses; at least one first optical element comprising a plurality of micro-to-nano-sized components, the plurality of micro-to-nano-sized components being shaped and arranged relative to each other in a manner that, when incident upon the plurality of micro-to-nano-sized components, a structure of the light pulses is modified to produce structured light, wherein the produced structured light is to be used to illuminate a user's eye when the head-mounted display apparatus is worn by the user; 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 of the reflections and a position of the reflections on an image plane of the at least one camera; and a processor coupled in communication with the at least one illuminator and the at least one camera, wherein the processor is 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.
