Hand Gesture Control Wheelchair for Disabled People

Abstract

A new assistive technology, called the Hand Gesture Control Wheelchair (HGCW) system, is designed to help individuals with mobility impairments increase their independence and mobility. The system consists of a wearable device with sensors that detect hand movements and Arduino microcontrollers for real-time data processing and wheelchair control. The HGCW system uses gesture recognition algorithms to translate hand gestures into corresponding wheelchair movements, such as forward, backward, left, and right turns, and communicates wirelessly with the wheelchair's control unit. The system is cost-effective, customizable, and intuitive, making it accessible to a wide range of users. The HGCW system has the potential to revolutionize the way disabled individuals navigate their environment, empowering them to lead more independent and fulfilling lives. By changing the head movement, the data is sent wirelessly to the microcontroller-based motor driver circuit to control the rotation of the chair in five different modes: forward, backward, right, left and special standing lock. The proposed system was assembled using products procured from the local market and its performance was tested in the laboratory and the test results are included in this article.
