Vision-based eye-gaze tracking for human computer interface

Eye-gaze is an input mode which has the potential for an efficient computer interface. Eye movement has been the focus of research in this area. Non-intrusive eye-gaze tracking that allows slight head movement is addressed in this paper. A small 2D mark is employed as a reference to compensate for this movement. The iris center has been chosen for the purposes of measuring eye movement. The gaze point is estimated after acquiring the eye movement data. Preliminary experimental results are given through a screen pointing application.
