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.
