Abstract

Although the opportunity of older adults to use personal computers is increasing more and more, the operation of a personal computer with a mouse is very annoying for older adults who cannot move his or her arm smoothly and effectively due to declined motor function. An attempt to move a cursor by an eye-gaze input system has been carried out as one solution to this problem. Until now, a menu selection method suitable for an eye-gaze input system has not been clarified. In this study, an effective menu selection method for the eye-gaze input system was identified as a basic design parameter to develop a usable Web browser using an eye-gaze input system. A menu selection method, that is, improved quick glance selection method (I-QGSM) was proposed. The effectiveness was evaluated by means of the pointing accuracy, the task completion time, and the psychological rating on usability. On the basis of the evaluation experiment, the proposed I-QGSM was found to be effective especially for older adults.
