## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to computer input devices.
2. Prior Art
Computer input devices include keyboards, mice, trackballs, touch pads, microphones, and cameras. Input devices that control cursor movement are also known as pointing devices, and include mice, trackballs, and touch pads. A conventional touch pad includes a flat, touch sensitive surface which tracks the movement of a fingertip across it. Touch pads are commonly found on portable or notebook computers. Although most input devices are connected to the computer with cords, cordless mice, trackballs, microphones, and cameras are also well known in the art. A conventional cordless input device includes a transmitter that remotely communicates with a receiver connected to the computer through a communications port, such as a USB (universal serial bus) port.
Since conventional input devices are controlled by hand, the user cannot perform other manual functions while using such input devices. Handicapped people without the use of their hands cannot use conventional input devices. Although input devices have been adapted for use by handicapped people, they are generally operated by a clumsy stick held in the mouth of the user.
The entire head must be moved to use the stick to operate a special keyboard or mouse. Since the head is heavy, it is limited to slow movements that result in slow computer operation. Further, moving the head repeatedly over long periods can cause fatigue and perhaps injury to the neck.

DETAILED DESCRIPTION OF THE INVENTION
FIGS. 1–2:
A preferred embodiment of the present mouth mounted input device 30 is shown in a side perspective view in FIG. 1 and in a sectional view inside a mouth in FIG. 2. It is comprised of a housing 10 with a convex top 11, a concave bottom 12, and a curved front edge 13. Top 11 and bottom 12 are generally curved about a longitudinal axis for closely engaging the roof of the mouth. Front edge 13 is generally curved about a vertical axis for closely engaging the back of the front teeth.
A first transceiver 14 is positioned inside housing 10 for communication with a second transceiver 15 connected to a computer 16 through a communications port, such as a USB port (the input device is shown out of scale with the computer). Computer 16 may be any type of computer, including a personal computer, a networked computer, a main frame computer, etc. Input device 30 may also be arranged to communicate with a miniature computer, such as a pocket-sized handheld computer 28 equipped with a transceiver 29.
Input device 30 includes a concave touch pad 17 conforming to concave bottom 12 of housing 10 for being touch by the tongue. Touch pad 17 is arranged to communicate touch information to computer 16. For example, the tip of the tongue is movable across touch pad 17 to move a cursor 18 across a display 19 connected to computer 16. Cursor control is thus provided without requiring a free or usable hand. Touch pad 17 may be arranged to perform the function of a joystick for controlling a computer game, driving a wheelchair, controlling an aircraft, or controlling other devices. Touch pad 17 may also be used for inputting Morse code, for example, by tapping. Input device 30 is thus suitable for use by people who do not have a free hand available for handling a conventional pointing device, or by handicapped people without the use of their hands.
An electrical stimulator 20 is arranged on top 11 of housing 10 for stimulating the roof of the mouth to present information received from the computer, such as alphanumeric information. Stimulator 20 is preferably comprised of an electrode that applies a noticeable but safe voltage to the mouth. The voltage may be applied in pulsed form, such as Morse code. Alternatively, stimulator 20 may be comprised of a tactile braille device with movable pins that present information in braille. A temperature sensor 26 and a pulse monitor 27 are also arranged on top of housing 10 for monitoring body temperature and heart rate.
A microphone 21 is positioned in housing 10 for enabling speech input or voice control of computer operation using conventional speech recognition software. Microphone 21 may be used to transmit voice communications, such as telephone communications, through a modem (not shown) in computer 16. An ear piece or speaker (not shown) may be connected to input device 30 and positioned in the ear for outputting audio information. Computer 16 may be arranged to recognize Morse code, such as by recognizing the clicking of the teeth picked up by microphone 21, and transmit the Morse code through transceiver 14.
A miniature camera 22 is positioned inside housing 10 for enabling video input. An elongated lens 23, such as a fiber optic lens, connected to camera 22 and projecting from the front of housing 10 is arranged to be positioned between two front teeth for providing a view in front of the user when the lips are open. Touch pad 17 is arranged for controlling focus and zooming of camera 22 by detecting the forward and backward movement of the tongue. Camera 22 is thus suitable for covert operations.
FIG. 3:
An electrical block diagram of input device 30 is shown in FIG. 3. First transceiver 14 is connected to touch pad 17, microphone 21, camera 22, stimulator 20, temperature sensor 26, and pulse monitor 27. Second transceiver 15 is connected to personal computer 16 through a communications port, such as a USB port. Inputs detected by touch pad 17, microphone 21, and camera 22 are transmitted to personal computer 16 by transceiver 14 and received by transceiver 15. Alphanumeric information from computer 16 is transmitted from transceiver 15 to transceiver 14, and presented to the user's mouth through stimulator 20.
FIG. 4:
In FIG. 4, input device 30 is arranged to communicate with a conventional home automation system 24 which is connected to a second transceiver 15 for controlling the operation of appliances 25, such as electrical lights, heaters, air conditioners, televisions, etc. Since controller 24 is programmed to recognize signals from its own transmitter (not shown), first transceiver 14 in input device 30 may be arranged to replace the original automation system transmitter by converting speech or touch pad input into signals recognizable by automation controller 24.
FIG. 5:
An alternative embodiment of the invention shown in FIG. 5 is comprised of an input device 31 with an embedded CPU or central processing unit 32. Temperature sensor 26, pulse monitor 27, touch pad 17, microphone 21, camera 22, stimulator 20, and transceiver 15 are connected to CPU 32. Input device 31 is operable independently of computer 16 (FIG. 1), so that it may be operated portably in a variety of environments. Input device 31 is arranged to communicate with a variety of compatible devices, including but not limited to 1) a computer 33 with transceiver 15 for controlling connected peripherals, such as a fax machine 34, a scanner 35, etc.; 2) an automotive computer 36 in a motor vehicle (not shown) with transceiver 15 for controlling vehicle components, such as a sound system 37, lights 38, etc.; 3) a satellite television receiver 39 with transceiver 15 for controlling operation of a connected television 40; and 4) an Internet or Web television receiver 41 with transceiver 15 for surfing the World Wide Web on television 40.
Accordingly, the present mouth mounted input device enables cursor control by the tongue with a touch pad in the mouth. It enables speech input from a microphone in the mouth. It enables video input from a camera in the mouth. It monitors body temperature and heart rate. It presents alphanumeric information to the user through a stimulator in the mouth. It also cordlessly connects to a personal computer or home automation system.
Although the foregoing description is specific, it should not be considered as a limitation on the scope of the invention, but only as an example of the preferred embodiment. Many variations are possible within the teachings of the invention. For example, the housing may be connected to the computer by a cable to eliminate the transceivers. Therefore, the scope of the invention should be determined by the appended claims and their legal equivalents, not by the examples given.
