Abstract:
A gaze-tracking system for use in a head-mounted display apparatus and an aperture device. The gaze-tracking system includes a first light source and a second light source operable to emit light of first and second type respectively; an image sensor operable to capture an image of the user's eye and reflections of the light of first type from the user's eye; a primary lens; an aperture device positioned between the image sensor and the primary lens, and a processor configured to control the first and second light sources and image sensor, and to process the captured image to detect a gaze direction of the user. The aperture device provides a first aperture to the light of first type and a second aperture to the light of second type, the first aperture and the second aperture being substantially concentric, the first aperture being smaller than the second aperture.

Claim (Index 15):
The aperture device of  claim 14 , wherein the first portion is made of a material that is substantially transparent to the light in the first wavelength range as well as the light in the second wavelength range.
