Abstract

A gaze tracker and a computer-implemented method for gaze tracking, comprising the steps of: recording video images of a being's eye such that an eye pupil and a glint on the eye ball caused by a light source ( ) are recorded; processing the video images to compute an offset between the position of the predetermined spatial feature and a predetermined position with respect to the glint; by means of the light source such as a display, emitting light from a light pattern at a location selected among a multitude of preconfigured locations of light patterns towards the being's eye; wherein the location is controlled by a feedback signal; controlling the location of the light pattern from one location to another location among the predefined locations of light patterns, in response to the offset, such that the predetermined position with respect to the glint caused by the light source tracks the predetermined spatial feature of the being's eye; wherein the above steps are repeated to establish a control loop with the location of the light pattern being controlled via the feedback signal.
