Eye movement based human computer interaction

With the advancement in technology the number of computing devices that a person uses is increasing and there is a need of faster and non-intrusive methods of communicating with these devices. In this regard, eye movement is a promising input medium for human computer interaction. In this paper we discussed various eye tracking techniques that can be used to find the line of gaze of the user. We then discussed some of the algorithms that can be used to implement these eye tracking techniques. The main aim of this paper is to propose new applications utilizing eye gaze that are suitable for standard user. These applications will enhance the reading experience of the user and make reading a more joyous task.
