Moving target acquisition by gaze pointing and button press using hand or foot

This work explores gaze-based interaction for moving target acquisition. In a pilot study, three interaction techniques are compared: gaze and manual button press (gaze + hand), gaze and foot button press (gaze + foot), and traditional mouse input. In a controlled scenario using a circle acquisition paradigm, participants perform moving target acquisition for targets differing in speed, direction of motion and motion pattern. The results show similar hit rates for the three techniques. Target acquisition completion time is significantly faster for the gaze-based techniques compared to mouse input.
