Abstract: With an increasing number of computer devices around us, and the increasing time we spend for interacting with such devices, we are vehemently motivated in finding new interaction methods which ease the use of computers or increase interaction efficiency. Eye tracking seems to be a promising technology to achieve this goal. This paper researches interaction methods based on eye gaze tracking technology with emphasis in PIN entry. Personal identification numbers (PINs) are one of the most common ways of electronic authentication these days and they are used in a wide variety of applications. The PIN-entry user study used three different gaze-based techniques for PIN entry. The first and second method used gaze pointing to enter the PIN on a number pad displayed on the screen. The first method used a dwell time of 800 milliseconds and the second method used a button, which had to be pressed when looking at the correct number on the number pad display. The second method was introduced as hardware key or gaze key, but called look & shoot method in the context of the user study as this name is self-explaining and got high acceptance by the participants. The third method used gaze gestures to enter the digits. The use of gaze gestures protects accidental input of wrong digits.
