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 22):
A method of  claim 14 , wherein the head-mounted display apparatus comprises at least one focus image renderer, at least one context image renderer and at least one optical combiner, the at least one optical combiner comprising at least one first optical element that is substantially transparent for infrared light, the at least one first optical element being positioned on an optical path of the reflections of the light pulses, wherein the method further comprises:\n (vii) rendering a focus image at the at least one focus image renderer, wherein an angular width of a projection of the rendered focus image ranges from 5 degrees to 60 degrees; (viii) rendering a context image at the at least one context image renderer, wherein an angular width of a projection of the rendered context image ranges from 40 degrees to 220 degrees; (ix) employing the at least one optical combiner to optically combine the projection of the rendered focus image with the projection of the rendered context image to create a visual scene to be presented to the user; and (x) positioning the at least one reflective element in a manner that the at least one reflective element hides behind a portion of the at least one first optical element upon which the projection of the focus image is incident.
