Smart Wheelchair Remotely Controlled by Hand Gestures

The main objective of this paper is to generate a hand gesture-controlled smart wheelchair for those physically challenged people who are incapable to move from one place to another in day-to-day life. Hand gesture-controlled wheelchair is a special kind of movable device which can control the motion of wheelchair at right direction through the hand movements of any person. This type of wheelchair is a blessing for those people who are not capable to move their lower limbs and are fully dependent on the caretaker for their activities. The proposed system can be categorized into two parts: gesture unit and wheelchair unit. A three-axis accelerometer ‘Micro-Electro-Mechanical Systems (MEMS)’ is used here as a sensor which is connected to the hand and sends the position of the hand to the microcontroller Arduino Lilypad. On the basis of data gathered from the accelerometer, microcontroller drives the signal to move the wheelchair in the desirable direction.
