Abstract: The Wheelchair chair is an assistive device used by the physically challenged people to move from one place to another. But there is some sort of difficulties in manual operation of the wheelchair by the physically challenged people. The main objective of this paper is to develop a wheelchair cum stretcher operated by the Head gestured recognition system. This provides mobility assistance and posture stability for bed ridden people and physically challenged people. The wheelchair can be converted to stretcher with the help of two-way electric actuator attached along with linkage mechanism provided in the back rest, seat, and leg rest portion of the wheelchair. The mobility is provided using the Head gestured recognition system operated with the help of the Arduino microcontroller and accelerometer sensor which is a 3 axes sensor used to sense the gesture of the user and manipulates the signal to the driving unit i.e. To the motor driver which transmits the signal to the DC geared motion to move the wheelchair forward, backward, left or right respectively.

Keywords: Arduino microcontroller, Accelerometer sensor, Two-way electric actuator, DC geared motor.
