Abstract: Eye input method has become a hotspot in the field of human-computer interaction for its fast feature and free of fatigue. This paper investigates the gaze-gesture interaction for mobile phones which is more suitable than the traditional method. Firstly, the paper designs twelve kinds of gaze gestures on the basis of prefix coding technology and uses them to input ten numbers, delete undesirable numbers and make a telephone call. Later, the paper designs the dedicated interface of human-computer interaction and uses it for analyzing and triggering the gaze gestures correctly. The gaze-gesture method is convenient, feasible and better according to the experiment results.
