Head Movement Based Assist System for Physically Challenged

An automated system was developed to control the motor rotation of a wheelchair based on the head movement of a person affected by Quadriplegia. People who are affected by this disease cannot move any of their body parts except their head. In order to facilitate these people for their independent movement, an accelerometer device is fixed on the forehead. Based on the head movement the accelerometer drives the motor connected to the wheel chair in any of the four directions. The automated wheelchair is based on simple electronic control system and the mechanical arrangement that is controlled by a Programmable Interface Controller. The vehicle can be driven at a normal speed. This device also helps people who have various other disabilities to sit on the chair and just hold the accelerometer and move it over to control the vehicle movements.
