Figure 1: We evaluate the performance of the three widely used gaze-based interaction methods: Dwell time (A), Pursuits (B) and Gaze gestures (C), for target selections on handheld mobile devices while sitting (left) and while walking (right). All participants performed all selections using the three different techniques while sitting and while walking. The red arrow in (B) illustrates the direction in which a yellow dot stimuli was rotating around a selectable target. The red arrows in (C) indicate the directions in which the user could perform a gaze gesture. All arrows are for illustration and were not shown to participants.
