Plataforma de comando por voz para uma cadeira de rodas motorizada

Abstract

In this work is developed a platform to control the movements of a motorized wheelchair using voice command by quadriplegics users or paraplegics with severe physical limitations in the upper limbs. It is implemented a interface circuit to send electrical signals that activate the directional commands from the chair and controls through a notebook. Thus, commands are sent to an interface circuit with a serial port communication of a notebook, using a software programmed in Java language. This software is able to recognize voice commands given by the user and convert them into signals to be sent to the interface circuit to move the wheelchair, in addition the software providing a local server to other remote device, such as mobile smartphones or tablets, communicate with the wheelchair, opening new prospects for work in the area. Therefore, this work provides a clear opportunity for improvement in mobility, accessibility and comfort of people with special needs, through a solution with a low cost of development.
