ABSTRACT
In this paper, we propose a mathematical model for a wide range gaze tracking system based on corneal reflections and pupil using calibrated stereo cameras and light sources. We demonstrate a general calculation method for estimating the optical axis of the eye for a combination of non-coaxial and coaxial configurations of many cameras and light sources. Gaze estimation is possible only when light is reflected from the spherical surface of the cornea. Moreover, we provide a method for calculating the eye rotation range where gaze tracking can be achieved, which is useful for positioning cameras and light sources in real world applications.
