Abstract

In this study, alternative methods to mouse click and drag & drop operations in the eye-gaze input system were discussed. The alternative methods to mouse click operation included the eye fixation, the press of space bar, and the wink (blink). The effectiveness was compared among three alternative methods. The percentage correct recognition, the task completion time, and the subjective rating of workload to upper body and usability were 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 task completion time became longer as follows : eye-gaze input system with eye fixation, mouse, eye-gaze input system with press of space bar, and eye-gaze input system with wink. The age factor was found not to affect the pointing performance so remarkably. The performance of drag & drop operation was also compared among the following input means : mouse, eye-gaze input system with space bar, eye-gaze input system with open and close of mouth. The task completion time of a mouse was, on average, by 30% shorter than that of an eye-gaze input system. In other words, it was found that the eye-gaze input system takes longer to carry out a drag & drop operation than a mouse.
