Abstract:
A gaze-tracking system for use in a head-mounted display apparatus. The gaze-tracking system includes at least one illuminator to emit light pulses for illuminating a user's eye; at least one camera to capture image of reflections of the light pulses; at least one reflective element arranged on an optical path of the reflections of the light pulses, such that when incident upon the at least one reflective element, the reflections of the light pulses are reflected towards the at least one camera; at least one actuator associated with the at least one reflective element, wherein the at least one actuator moves the at least one reflective element; and a processor configured to: process the at least one image to detect a gaze direction of user; and control the at least one actuator to adjust, based upon the detected gaze direction, position of the at least one reflective element.

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, the at least one illuminator being operable to emit light pulses, wherein the light pulses are to be used to illuminate a user's eye when the head-mounted display apparatus is worn by the user; at least one camera, the at least one camera being operable to capture at least one image of reflections of the light pulses from the user's eye; at least one reflective element, wherein the at least one reflective element is to be arranged on an optical path of the reflections of the light pulses, such that when incident upon the at least one reflective element, the reflections of the light pulses are reflected towards the at least one camera; at least one actuator associated with the at least one reflective element, wherein the at least one actuator is to be employed to move the at least one reflective element; and a processor coupled in communication with the at least one illuminator, the at least one camera and the at least one actuator, the processor being configured to: (i) process the at least one image to detect a gaze direction of the user; and (ii) control the at least one actuator to adjust, based upon the detected gaze direction of the user, a position of the at least one reflective element; wherein the at least one camera is operable to capture at least two images of the reflections of the light pulses, and wherein the processor is configured to:\n control the at least one actuator to move the at least one reflective element to a first position; \n control the at least one camera to capture a first image of the reflections of the light pulses, when the at least one reflective element is arranged at the first position: \n control the at least one actuator to move the at least one reflective element to a second position, wherein the second position is different from the first position; and \n control the at least one camera to capture a second image of the reflections of the light pulses, when the at least one reflective element is arranged at the second position.
