Eye tracker and method of eliminating the visibility of infrared diodes when using the eye tracker in low light conditions

Abstract

An eye-tracker for tracking eyeball movement, designed to be used effectively even in low light conditions, comprising a frame (1) in the front of which are located spectacle discs (1a) with infrared diodes (2) installed therein, is characterized in that it is equipped with illuminators (3) for said infrared diodes (2). A method for eliminating the visibility of infrared diodes when using the eye-tracker in low light conditions is characterized in that the illuminators (3) are used to modify the lighting conditions behind the rear surface of the front of the eye-tracker frame (1). The device for eliminating the visibility of infrared diodes in the eye-tracker is characterized in that it is in the form of an eye-tracker attachment in which the illuminators (3) are built.
