In this study, alternative methods of mouse click operation were discussed.The eye-gaze input system was used.The effectiveness was compared among three alternative methods of mouse click operation.The alternative methods in the eye-gaze input system included the eye fixation, the press of space button, and the wink (blink).The percentage correct recognition, the pointing time, the subjective evaluation of usability was used as evaluation measures.The arrangement of targets (vertical or horizontal) and the age were also considered as experimental factors, and it was explored how these factors affected the pointing performance.The percentage correct recognition of the horizontal direction was higher than that of the vertical direction.The pointing time became longer as follows: eye-gaze input system with eye fixation, mouse, eye-gaze input system with press of space button, and eye-gaze input system with wink.The age factor was found not to affect the pointing time so remarkably.
