The eye-controlled wheelchair is a flexible device for persons with restrained or severe locomotor disabilities, ameliorating movement further for the aged. There are numerous interfaces for wheelchair obtainable within the market, but still, they continue to be under-utilized because they require the presence of mind, ability, and power to control them. The proposed model is an alternative that tries to form the lives of those individuals easy by helping them move around as they wish and not a burden on others. An individual littered with paralysis will move his eyes and may tilt his head partially. Thus, A wheelchair that is totally controlled with eye movements and blinks has been designed in which python software is used & processing of eyeball movement is done which employs the Histogram of Oriented Gradients (HOG) algorithm. The Arduino drives the motor driver circuit. The motors connected to the wheelchair support differential steering that avoids clumsy motion. The wheelchair has been supplied with a joystick to make sure safe movement just in case of tired vision and with a security stop button, which is able to prevent the wheelchair movement at his own case.
