In this work we describe a method of pupil detection for subsequent gaze tracking, when specular reflection is present in the image. Gaze tracking commonly uses the spatial relationship between the pupil and corneal reflection, but is not robust when the user is wearing eyeglasses, since light reflected from the surroundings changes the appearance of the pupil. In this research we propose and evaluate a pupil detection method that can perform robustly even in the presence of such reflection.
