What you don't look at is what you get: anti-saccades can reduce the midas touch-problem

ABSTRACT

Controlling computers by eyes can provide a fast and efficient alternative to the computer mouse. However, in gaze controlled systems object selection is still suboptimal: Dwell times on a certain object typically used to elicit the selection of this object can cause unintended selections; a problem known as Midas Touch. For our suggested alternative approach using anti-saccades for selection, highlighted objects are copied to one side of the object. The object is selected when fixating to the side opposed to that copy requiring to inhibit an automatic response towards new objects. A user study revealed shorter task completion times, but more errors when selecting objects by anti-saccades relative to selection by individually and task-specifically adapted dwell times. With certain improvements, anti-saccades can become a serious alternative to dwell times.
