Description

A pointing input method that uses gaze detection, along with a mouse, is proposed. This method enhances the efficiency of the pointing task in a man-machine interface. In this method, a cursor is displayed at the detected gaze point on the CRT and if the cursor is on target, the operator clicks the mouse button. If it is not on target, it is moved onto the target using the mouse and then the button is clicked. This method is compared to the conventional method, which uses only a mouse, and pointing time, error rate, and gaze point movement are analyzed. The results indicate that if the gaze detection device has an error angle of 3 degrees or less (at a sight distance of 60 cm), this method is better than the conventional method in terms of pointing time and cursor controllability.
