Abstract:
A gaze-tracking system for use in a head-mounted display apparatus. The gaze-tracking system includes: at least one first optical element comprising particles of a phosphorescent or fluorescent material dispersed therein, the particles of the phosphorescent or fluorescent material being dispersed in a manner that when excited by electromagnetic radiation incident thereupon, the particles produce structured light of a given wavelength, wherein the produced structured light illuminates 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 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 camera, wherein the processor is configured to process the captured image to detect a gaze direction of the user.

Claim (Index 3):
The gaze-tracking system of  claim 1 , wherein the head-mounted display apparatus comprises at least one image renderer for rendering an input image, and wherein the particles of the phosphorescent or fluorescent material are to be excited by the electromagnetic radiation produced by the at least one image renderer, so as to produce the structured light of the given wavelength.
