Infrared wheelchair controls.
A joystick controlled wheelchair can be an awkward steering apparatus for a person with poor motor skills. An alternate steering apparatus would be a set of four sensors placed underneath a wheelchair's lapboard. There would be one set of sensors for each direction the wheelchair can move. When an object is placed over the sensors, the wheelchair will move in the direction signaled by the object.
