The tracking of such reflections and the pupil center provides input to gaze tracking. A method for equipping and an LCD with a reference illuminator are also provided. Also provides are a system and method for determining a gaze point of an eye watching a visual display that includes reference illuminators. The determination of the gaze point may be based on an ellipsoidal cornea model."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Visual display with illuminators for gaze tracking","description":"A visual display includes hidden reference illuminators adapted to emit invisible light for generating corneo-scleral reflections on an eye watching a screen surface of the display.
