Instantaneous saccade driven eye gaze interaction

In this paper, we introduce and evaluate a new Instantaneous Saccade (IS) selection scheme for eye gaze driven interfaces where the speed of the target selection is of utmost importance. In the IS selection scheme, target selection occurs at the start (onset) of a saccade requiring only constant amount of time to be completed. The IS performance is compared to the conventional Dwell Time (DT) selection scheme where target selection is triggered when a user fixates on an object for a certain amount of time. The IS method is also compared to the Saccade Offset (SO) selection scheme where target selection occurs at the end of a saccade. All three schemes were evaluated in terms of task completion time and the throughput of input performance in horizontal target selection task by six subjects. Results show that the Instantaneous Saccade selection was 57% faster than the DT selection to complete a task. In terms of throughput comparison,
