Abstract
Haptic feedback can improve the usability of gaze gestures in mobile devices. However, the benefit is highly sensitive to the exact timing of the feedback. In practical systems the processing and transmission of signals takes some time, and the feedback may be delayed. We conducted an experiment to determine limits on the feedback delays. The results show that when the delays increase to 200 ms or longer the task completion times are significantly longer than with shorter delays.
