Abstract
Eye-gaze is an input mode which has the potential of an efficient computer interface. Eye movement has been the focus of research in this area. Non-intrusive eyegaze 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 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.
Introduction
Human-computer interaction has become an increasingly important part of our daily lives. The movement of userâ„¢s eyes can provide a convenient, natural and high-bandwidth source of input. By tracking the direction of gaze of the user, the bandwidth of communication from the user to the computer can be increased by using the information about what the user is looking at, and even designing objects specially intended for the user to look at. A variety of eye-gaze (eye-movement) tracking techniques have been reported in the literature .A short list includes Electra-Oculography ,Limbus, Pupil and Eyelid Tracking Contact Lens Method, Cornea1 and Pupil Reflection Relationship Purkinje Image Tracking, Artificial Neural Networks [lo] and Head Movement Measurement ,Computer vision is intrinsically non-intrusive, and does not require any overly expensive equipment. Nonobtrusive sensing technology - such as video cameras and microphones - has received special attention in this regard. This seminar draws on computer vision and image processing techniques for measuring eye-gaze
