Multi-Controlled Wheelchair for Upper Extremities Disability

Abstract

People with motor disabilities are trying to be more autonomous by using an electric wheelchair with a conventional joystick control. However, a problem arises when these people are suffering from upper extremities disability such as tetraplegia. Several methods were implemented such as voice control, chin control, eye-blink, sip-and-puff, but each has its advantages and disadvantages. Furthermore, in some situations a method is preferred to others. In this paper, we suggest a methodology that incorporates multiple control methods for a wheelchair. Voice control, eye-blink and sipand-puff controllers will all be included in the same wheelchair. The user has the option to choose which one he will use whenever he wants. This helps the individual with disability to be more autonomous because he decides the method that suits him better at any particular time.

A Novel Approach to Wheelchair Design and Operation Using Multi-Function Controller

“…The Sip-and-puff controller is an assistive technology that sends signals using air pressure by Sipping or puffing through a tube in order to move the electric wheelchair which is perfect for individuals who have restricted limbs movements to operate the wheelchair and for people affected with severe motor disabilities, as manipulating a standard switch can be difficult, tiring and in some cases impossible (Riman, 2018).…”
