The camera is placed so as to capture the movement of one eye allowing clear vision to the other eye. The camera will take an image of the eyes that will be sent to the laptop where the images are being processed.
Once the image has been processed it moves onto the second part, the microcontroller. The system consists of eye tracking webcam, microcontroller, motor, chair image processing unit and associated circuits. The system works by tracking the motion of eyeball using a webcam.
