Multi-Controlled Wheelchair for Upper Extremities Disability

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 sip-and-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.
