Abstract
Abstract A cranial controller for supplying directional signals to a computer input is provided in which the controller is affixed to the head of an incapacitated user and by selectively moving his or her head one of several mercury switches is activated to send a directional control signal corresponding to the selected cranial movement to a computer console or video device. In addition, the user's mouth provides a pressure source for activating a vacuum controlled switch in the controller for providing a function signal to the computer input.
