Computer interaction based on voluntary ocular motility for the physically challenged

Ocular Motility is a promising mode of input for human computer interaction. However, we are yet to engineer an application that is cost-effective, robust, user-friendly and far reaching. In this paper we describe an eye-controlled application which will be beneficial to the physically challenged community. Even people who can move only their eyes can use this with ease. This works on principles of Image processing and translates the eye movements into mouse commands, thereby enabling the physically challenged to interact with a computer. A user friendly graphical user interface has been developed to demonstrate the merits of eye controlled input as a natural mode of human-machine interaction.
