Eye-mouse under large head movement for human-computer interface

An eye gaze estimation system is proposed. The eye gaze estimation system estimates the eye-gaze direction of a user. The proposed system consisted of five IR LEDs and a CCD camera. The direction of the user's eye gaze can be computed without computing the geometrical relation among the eye, the camera, and the monitor in 3D space. Our method is comparatively simple and fast. The disabled can manipulate a computer using this system. We would introduce our method and show experimental results. The experimental results verify the feasibility of the proposed system as an interface for the disabled.
