Abstract
An eye-tracking apparatus. At least one light source and a plurality of sensors are arranged at a periphery of a first surface of at least one lens. A frame is employed to hold the at least one lens. A processor coupled to the at least one light source and the plurality of sensors is configured to control the at least one light source to emit light towards the user's eye, control the plurality of sensors to sense reflections of the light off a surface of the user's eye, and process sensor data pertaining to the sensed reflections to determine a gaze direction of the user's eye.
