Smart wheelchair integrating head gesture navigation

Science and technology have been improving day by day. Smart technology is augmenting the living standard of the human. Smart wheelchair is a paradigm of smart technology. The main ambition behind the titled project is to introduce a smart wheelchair which will be navigated with different head gestures of the user. The proposed wheelchair has been associated with exclusive features to make the movement more comfortable and convenient. Accelerometer sensor has been used to move the wheelchair in five different directions according to different head gestures. Two DC motors have been incorporated to move the wheels in different position. Arduino UNO controls the direction of the wheelchair using Relay as the motor driver. The wheelchair has been powered by solar panel thus providing emphasize on the use of green energy. LDR has been used as light detection sensor which would help the user to move when there is inadequate light. Seat belt sensor has been used as a switch to provide secure movement. Ultrasonic sensor has been used as the obstacle detector for making the movement safer. At last, the operation of the entire system has been observed and commendable outcomes have been achieved to make the smart wheelchair efficient and effective for the user.
