Design of Hand Gesture Control Wheel Chair

Abstract

This study designated a wheelchair which can be meticulous using the user hand gesture. The purpose of this research was to come up with a hand gesture powered wheelchair system intended to provide assistance with the use of hand directions, which would allow users to travel efficiently and with greater ease. The system is made up of various electronics components such as the microcontroller, accelerometer, Bluetooth model, ultrasonic sensor, motor driver, among others. The microcontroller is programmed. The transmitter circuit board is made up of accelerometer sensor like ADSL335 which is able to sense three parameters. The microcontroller forms the main part or the brain of the system, and performs most of the functions. The microcontroller sends the readings sensed by the hand to the Bluetooth transmitter. The ultrasonic sensor detected obstacles, also sent the distance measured to the microcontroller. The microcontroller processed the information to the motor driver. The motor driver then powered the motors to either move forward or backward. It was observed that when the system was activated, the movement of the Wheelchair immediately start to follow the orientation of the user’s hand. The wheelchair was able to be perform five (5) different gestures. The gesture follows the range that had been set. However, this range depends on the position of the accelerometer.
