Revolutionizing mobility with hand gesture recognition technology

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.
