Abstract :
Video-based eye-gaze point detection methods used in the support systems for the disabled have been studied. Recently, we proposed the pupil detection technique using two light sources and the image difference method, and presented its effectiveness. In this paper, a method eliminating the light sources reflected in eye glass lenses and precisely detecting the pupil and the glint (the corneal reflection light), which are the feature points for the determination of the eye-gaze point, were proposed
