Real Time Eye Tracking and Mouse Control for Physically Disabled

In the cases of paralysis a person’s ability to move may be limited to the muscles around the eyes, which may be the only way for him to communicate. We developed a computationally efficient and cost effective application for controlling the mouse cursor using the eye ball by real time tracking using a USB camera. Eye ball movement can be followed by obtaining the image of the eye. The glint in the eye acts as the Region of Interest and can be located in the real time images of the eye. We begin with the extraction of human face and its features from a video stream. These extracted features, are tracked and monitored to detect any movements which form the basis of various actions. The LabVIEW VI gives the coordinates of the glint which are input the cursor to change its position in response to the movement of the eye.
