Button selection for general GUIs using eye and hand together

Abstract

This paper proposes an efficient technique for eye gaze interface suitable for the general GUI environments such as Microsoft Windows. Our technique uses an eye and a hand together: the eye for moving cursors onto the GUI button (move operation), and the hand for pushing the GUI button (push operation). We also propose the following two techniques to assist the move operation: (1) Automatic adjustment and (2) Manual adjustment. In the automatic adjustment, the cursor automatically moves to the closest GUI button when we push a mouse button. In the manual adjustment, we can move the cursor roughly by an eye, then move it a little more by the mouse onto the GUI button. In the experiment to evaluate our method, GUI button selection by manual adjustment showed better performance than the selection by a mouse even in the situation that has many small GUI buttons placed very closely each other on the GUI.
