This paper investigates novel ways to direct computers by eye gaze. Instead of using fixations and dwell times, this work focuses on eye motion, in particular gaze gestures. Gaze gestures are insensitive to accuracy problems and immune against calibration shift. A user study indicates that users are able to perform complex gaze gestures intentionally and investigates which gestures occur unintentionally during normal interaction with the computer. Further experiments show how gaze gestures can be integrated into working with standard desktop applications and controlling media devices.
