Abstract: A mouth mounted computer input device is comprised of a curved housing shaped to closely engage the roof of the mouth against the front teeth. A touch pad is arranged on the bottom of the housing, and an electrical stimulator is arranged on the top of the housing. A microphone, a camera, a temperature sensor, a pulse monitor, and a first transceiver are also positioned in the housing. A fiber optic lens connected to the camera and projecting from the housing is arranged to be positioned between two front teeth. A second transceiver is connected to a personal computer. The touch pad is operable by the tongue for cursor control. The stimulator provides pulsed electrical stimulation to the mouth to present alphanumeric information. The microphone enables speech input, and the camera enables video input, the temperature sensor measures body temperature, and the pulse monitor measures heart rate.
