Input method using divergence eye movement

Abstract

A gaze input interface offers hands-free operation by using the view-point position as the cursor coordinates on the display. However, the selection operation of a button is indistinguishable from viewing; this is known as the Midas touch problem. We propose a new input method that measures divergence eye movement, thereby enabling users to "press" a button by moving their viewpoint forward. Comparison of our method and the conventional blinking input method confirms that input speed and accuracy are similar.
