摘要：

This paper addresses the accuracy problem of an eye gaze tracking system, We first analyse the technical barrier for a gaze tracking system to achieve desired accuracy, and then propose a subpixel tracking method to break the barrier. We present new algorithms for detecting the inner eye corner and the center of an iris in subpixel accuracy, and we apply these new methods in developing a real-time gaze tracking system The experimental results indicate that the new methods achieve an average accuracy to within 1, 4 degrees using normal eye image resolutions.
