Abstract:
An apparatus ( 100 ) for deriving a gaze direction of a human eye ( 150 ) includes a light-guide optical element (LOE) ( 120 ) having pair of parallel faces ( 104 a ), ( 104 b ) deployed in facing relation to the eye ( 150 ). A coupling-in configuration, such as a set of partially-reflective surfaces ( 145 ), is associated with LOE ( 120 ) and configured for coupling-in a proportion of light incident on face ( 104 a ) so as to propagate within the LOE. Focusing optics ( 106 ) associated with LOE ( 120 ) converts sets of parallel light rays propagating within the LOE into converging beams of captured light which are sensed by an optical sensor ( 125 ). A processing system ( 108 ) processes signals from the optical sensor ( 125 ) to derive a current gaze direction of the eye. Despite the aperture-combining effect of the LOE, retinal images can be effectively recovered as the only image information brought to focus on the optical sensor.

Claim (Index 6):
The apparatus of  claim 1 , further comprising an illumination arrangement deployed to illuminate the eye from the direction of said coupling-in region.
