The Development of Eye Controlled HCI System for Paralytic Person

Abstract

The HCI system is designed for the person with absolutely no speech, no mobility. The method which is presented here is the HCI system based on an idea wherethe position of person's gaze is directly related to the relative position of the mouse pointer. System has been developed to provide computer access for people with severe disabilities. The system tracks the computer user’s eye movements with a video camera and translates them into movement of the mouse pointer on the screen. In the proposed system, tracking of the user’s eye at particular position for certain period of time and then enable mouse click is introduced. The objective of the present chapter is threefold. First, we capture the real time image from video camera. Second, we execute various methods for image processing in which we convert image into grayscale and then we detect the edges and circle. Third, movement of Mouse Pointer on the GUI with respect to the eye movement as an input mechanism to drive system interaction.
