Development and testing of intelligent low-cost wheelchair controller for quadriplegics and paralysis patients

Abstract

In this research, the development and testing of an intelligent wheelchair controller are presented. The system has been designed to help disabled and quadriplegic patients who have lost the ability to control their upper and lower limbs to use an electrical wheelchair without using joystick controller. The controller includes two sub-controllers operating in parallel which are voice and head tilts controllers. The system design is based on using two different voice recognition modules and two sophisticated orientation detection modules as input sensors, a powerful microcontroller for data processing and decision making, and a traditional electrical wheelchair as an output unit.
