A design of a microcontroller-based wheelchair controlled by the motion of the eye is presented. The user wears a set of electronic eyeglasses used to detect the movement of the sclera and then transmits control signals to the wheelchair via Bluetooth. Detection of sclera movement is done via infrared sensors. The wheelchair is equipped with an obstacle detection system utilizing ultrasonic sensors. To operate the wheelchair, the user presses a button to move forward, and moves his eyes to turn the chair in a specific direction. The sensors can detect four directions of eye movement: half left, full left, half right and full right. Tests for response to eye movement, delay in the transmission of control signals, reliability of transmission and reliability of the ultrasonic sensors in terms of obstacle detection shows that the design met the objectives to ensure proper and safe operation of the wheelchair.
