Abstract

As almost all of existing eye-gaze input devices suffers from fine and frequent shaking of fixation points, an effective and stable estimation method of fixation points has been proposed so that the obtained stable fixation points enabled users to point even to a smaller target easily. An estimation algorithm was based on the image processing technique (Hough transformation). An experiment was carried out to verify the effectiveness of eye-gaze input system that made use of the proposed estimation method of fixation point. From both evaluation measures, the proposed method was found to assure more stable cursor movement than the traditional and commercial method.
