Abstract:

A brainwave responsive wheelchair for providing control of an electric wheelchair by a physically handicapped person, includes a wheelchair having a seat portion, a back portion, a pair of back wheels and a pair of front wheels. A motor for selectively rotating the back wheels independent of each other is mechanically coupled to the back wheels. An actuator for selectively rotating the back wheels is operationally coupled to the motor. The actuator is mounted to the back portion and includes a control that is electrically coupled to the motor. A brainwave responsive device is operationally coupled to the control. The brainwave responsive device includes an input device. The input device is electrically coupled to the control and adapted for reading brainwaves. The control actuates the motor with respect to distinct brainwave patterns.
