A Novel Neural Eye Gaze Tracker

Diego Torricelli, Michela Goffredo, Silvia Conforto, Maurizio Schmid, Tommaso D’Alessio


A gaze tracking system, based on a novel neural approach, is proposed. The work is part of a wider research project concerning the development of human computer interfaces (HCI) addressed to disabled people, that could overcome the drawbacks of most of the existing methods for gaze tracking that require either intrusive devices or expensive equipment. This work, instead, aims at developing a low cost, completely non-intrusive and self-calibrating system which combines different techniques for three blocks in Eye Gaze Tracking, i.e. blink detection, feature extraction and neural computing. The experimental results show good accuracy in eye gaze tracking (rmse < 1 degree), and adequate generalization performance (rmse < 2 degrees).
