Hand Gesture Controlled Wheelchair

Abstract

The percentage of disabled people has
increased in both rural and urban part of India. The
disability could be by birth or due to some medical or
accidental reason. The aim of this project is to make a
hand gesture-controlled wheel chair and using
Accelerometer as sensor to help the physically disabled
people in moving from one place to another just by giving
direction from the hand. By addressing the limitations of
conventional controls, the hand gesture-controlled
wheelchair aims to enhance accessibility, simplify control
mechanisms, reduce the learning curve, and offer
customization options. This solution will provide
individuals with a more intuitive and natural means of
controlling their wheelchair, improving their overall
mobility and independence. This wheel chair works by the
hand signals given from the user which are taken from
the 3-axis accelerometer which will help the user to
control the chair through hand gestures. The system
comprises of two main parts: Transmitter part and
receiver part. In transmitter part the hand gesture is
recognized by the sensor, digital output is transmitted to
the controller and then transmitted to receiver side by the
RF transmitter. The same data is received at receiver side
by the RF receiver. DC motors which are interfaced to the
controller by the motor driver controls the direction of the
wheel chair.
