Abstract

One of the general problems of the pupil-corneal reflection-based gaze detection systems is that the frames and lens of eyeglasses produce reflection images of the light sources in the camera image when a user wears eyeglasses. The glass reflections tend to be misdetected as the pupil and corneal reflections. In the present paper, we propose a novel geometrical methodology based on the optical structure of the eyeball to detect a true pair of the pupil and corneal reflection. The experimental results show that the proposed method improved the precision of gaze detection when the subjects wore glasses or when disturbance light sources existed.
