Both Fingers And Head Are Acceptable In Sensing Tactile Feedback Of Gaze Gestures

Larger tablet computers are not always easy to use in handheld configurations. Gaze input and especially gaze gestures provide an alternative input technology in such situations. We investigated the task performance and user experience in gaze gesture use when haptic feedback was provided either to fingers touching the tablet or behind the ears through the eyeglass frame. The participant's task was to look at a display and complete simple two-stroke gaze gestures consisting of either one, two, or three repetitions. The results showed that the participants found feedback on both body locations to be equally pleasant and preferred haptic feedback to no feedback. Also, the participants favored feedback that was spatially congruent with gaze movement.
