A text input method that uses eye tracking technology to allow users to type by looking at keys on a virtual on-screen keyboard. The most common technique is dwell-based selection, where the user fixates on a letter for a set duration (typically 300-1000 milliseconds) to select…

Gazepoint(also: Gaze Point, Point of Gaze)
