Visual display with illuminators for gaze tracking |
摘要 |
A visual display characterized by hidden reference illuminators is adapted to emit invisible light for generating corneo-scleral reflections on an eye watching a screen surface of the display. The tracking of such reflections and the pupil center provides input for gaze tracking. A method for equipping and an LCD with a reference illuminator are also provided. A system and method for determining a gaze point of an eye watching a visual display comprising reference illuminators are further provided. The determination of the gaze point may be based on an ellipsoidal cornea model.
