Abstract
We propose a method combining eye-gaze detection and PupilMouse to use for communicators for severely physically handicapped people. Both methods are based on remote pupil detection with a near-infrared light source. We had already implemented those methods in similar systems . With PupilMouse, the cursor on the PC display screen is moved smoothly and accurately based on the pupil movements in the camera image caused by the user ' s head movement. In contrast, with the eye-gaze detection method, the cursor moves quickly by shifting the eye-gaze point on the screen and arrives at an inaccurate eye-gaze position. In the proposed method, to use the advantages of both methods, the method is switched in accordance with the speed of the eye-gaze shift. The experimental results show that the proposed method enables characters to be inputs more quickly, accurately, and comfortably than when using one of the two conventional methods.
