‘Head movement controlled power wheelchair’ materializes the novel idea of a low cost, hands — free electronic vehicle for quadriplegics. Herein the control of the wheelchair rests with the user’s head movement. Turning the head in a particular direction results in the movement of the vehicle in that direction. By turning his/her head down, right and left, the user can drive the wheelchair straight, right and left respectively. The principle of LDRs is used for the detection of head movement. The power wheelchair control is based on the microcontroller platform. The whole idea is to bring in a certain degree of self sufficiency in the movement of quadriplegics.
