Gaze selection by dwell, magnification or zoom

Dwell is the traditional way of making selections by gaze. In the video we compare dwell to magnification and zoom. While the hit-rate is 10 % with dwell on a 12 x 12 pixels target, it is 100 % for both magnification and zoom. Magnification is a two-step process though, while zoom only takes on selection. In the experiment, the initiation of a selection is done by pressing the spacebar. Normally, the gaze tracking system will do this automatically when the gaze remains within a limited area for more than approx. 100 ms.
