Abstract
Electromyogram (EMG) signal generated by voluntary contraction of muscles is often used in rehabilitation devices because of its distinct output characteristics compared to other bio-signals. This idea proposes a wearable EMG-based human-computer interface (HCI) for electric-powered wheelchair users with motor disabilities by C4 or C5 level spinal cord injury. Many disabled people usually depend on others in their daily life especially in getting from one place to another. For the wheelchair users, they need continuously someone to help them in getting the wheelchair moving. By having a wheelchair control system they become more independent. The system uses the shoulder for triggering and controlling all its movements. The wheelchair responds to the movement of the shoulder from its user to perform any movements functions. It integrates a muscle contraction, microcontroller and motor control interface board to move the wheelchair.
