AUTONOMOUS EYE.

A powered wheel chair is a mobility-aided device for persons with moderate or severe physical disabilities. In order to take care of people with different disabilities, various kinds of interfaces have been developed for powered wheelchair control; such as joystick control, head control, chin control and sip-puff control. Many people with disabilities do not have the ability to control powered wheel chair using the above mentioned interfaces. In this project work, we propose and implement an eye controlled wheelchair system in which the control of the wheelchair is done as per the movement of eye. For this purpose, we use the optical-type eye tracking system to control powered wheel chair. User‘s eye movement are translated to screen position using the optical type eye tracking system. When user looks at appropriate direction, then computer input system will detect the direction, based on the coordinate position of pupil i.e., when user moves his eyes balls up (move forward), left (move left), right (move right), down (move backward) and in all other cases wheel chair will stop. The image captured by a camera after being processed it is fed to the microprocessor. The microprocessor will take a USB output from the laptop and convert the data into signals that will be sent to the wheelchair wheels for movement. Also, the object detection sensors will be connected to our microprocessor to provide necessary feedback for proper operation of the wheelchair system. In the case of the wheelchair, the front two wheels will be used for steering left and right and rear wheels provide the forward movement. All four wheels will be connected to our microprocessor that will send signals to control the wheels and thus the overall movement.
