Abstract

A mouth-operated computer input device includes a mouthpiece to be positioned in a user'"'"'s mouth, and an optical device carried by the mouthpiece for emitting light from a surface area thereof. The optical device controls movement of a cursor on a computer display based upon movement of the user'"'"'s tongue across the surface area. The optical device includes a light emitting device for emitting the light, and a sensor adjacent the light emitting device for sensing the light reflected from the user'"'"'s tongue. A processor calculates movement of the user'"'"'s tongue based upon the light reflected therefrom.

Claims

1. A mouth-operated computer input device comprising:

a mouthpiece to be positioned in a user'"'"'s mouth; and

an optical device carried by said mouthpiece for emitting light from a surface area thereof towards the user'"'"'s tongue, and for controlling movement of a cursor on a computer display based upon movement of the user'"'"'s tongue across the surface area, said optical device comprising

an optical window within the surface area,

at least one light emitting device for emitting the light through the optical window towards the user'"'"'s tongue, and

a sensor adjacent said at least one light emitting device for sensing the light reflected from the user'"'"'s tongue back into the optical window.

2. A mouth-operated computer input device according to claim 1 wherein said at least one light emitting device comprises at least one of a light emitting diode and a laser diode.

3. A mouth-operated computer input device according to claim 1 wherein said sensor comprises a digital camera.

4. A mouth-operated computer input device according to claim 1 wherein said optical device further comprises a processor for calculating movement of the user'"'"'s tongue based upon the light reflected from the user'"'"'s tongue.

5. A mouth-operated computer input device according to claim 1 further comprising a first switch carried by said mouthpiece for clicking and dragging the cursor on the computer display based upon activation of said first switch.

6. A mouth-operated computer input device according to claim 1 wherein the cursor is generated based upon a windows-based operating system;

and further comprising a second switch carried by said mouthpiece for generating a pop-up window on the computer display based upon activation of said second switch.

7. A mouth-operated computer input device according to claim 1 wherein the cursor is generated based upon a computer system;

and further comprising a cable coupled to said optical device for interfacing with the computer system.

8. A mouth-operated computer input device according to claim 7 wherein the cable comprises at least one of a universal serial bus (USB) cable and a firewire cable.

9. A mouth-operated computer input device according to claim 1 wherein the cursor is generated based upon a computer system;

and further comprising a wireless transmitter carried by said mouthpiece for interfacing with the computer system.

10. A mouth-operated computer input device according to claim 1 wherein said mouthpiece is horseshoe shaped and surrounds a row of teeth in the user'"'"'s mouth.

11. A mouth-operated computer input device according to claim 10 wherein the surface area of said optical device forms a bridge across the horseshoe shaped mouthpiece.

12. A mouth-operated computer input device comprising:

a horseshoe-shaped mouthpiece to be positioned in a user'"'"'s mouth; and

an optical device carried by said mouthpiece and comprising a surface area forming a bridge, across said mouthpiece, said optical device for emitting light from the surface area thereof towards the user'"'"'s tongue, and for controlling movement of a cursor on a computer display based upon movement of the user'"'"'s tongue across said surface area, said optical device comprising

an optical window within the surface area,

at least one light emitting device for emitting the light through the optical window towards the user'"'"'s tongue, and

a sensor adjacent said at least one light emitting device for sensing the light reflected from the user'"'"'s tongue back into the optical window.

13. A mouth-operated computer input device according to claim 12 wherein said optical device further comprises a processor for calculating movement of the user'"'"'s tongue based upon the light reflected from the user'"'"'s tongue.

14. A mouth-operated computer input device according to claim 12 wherein the cursor is generated based upon a windows-based operating system;

and further comprising;

a first switch carried by said mouthpiece for clicking and dragging the cursor on the computer display based upon activation of said first switch; and

a second switch carried by said mouthpiece for generating a pop-up window on the computer display based upon activation of said second switch.

15. A mouth-operated computer input device according to claim 12 wherein said optical device communicates to the computer display via a wired connection.

16. A mouth-operated computer input device according to claim 12 wherein said optical device communicates to the computer display via a wireless connection.

17. A method for controlling movement of a cursor on a computer display using a mouth-operated computer input device comprising a mouthpiece, and an optical device carried by the mouthpiece for emitting light from a surface area thereof, the method comprising:

inserting the mouth-operated computer input device into the user'"'"'s mouth; and

moving the user'"'"'s tongue across the surface area of the optical device, with the optical device controlling movement of the cursor based upon movement of the user'"'"'s tongue across the surface area, with the optical device comprising an optical window within the surface area, at least one light emitting device for emitting the light through the optical window towards the user'"'"'s tongue, and a sensor adjacent the at least one light emitting device for sensing the light reflected from the user'"'"'s tongue back into the optical window.

18. A method according to claim 17 wherein the optical device further comprises a processor for calculating movement of the user'"'"'s tongue based upon the light reflected from the user'"'"'s tongue.

19. A method according to claim 17 wherein the mouth-operated computer input device further comprises a first switch carried by the mouthpiece for clicking and dragging the cursor on the computer display based upon activation of the first switch.

20. A method according to claim 17 wherein the cursor is generated based upon a windows-based operating system;

and wherein the mouth-operated computer input device further comprises a second switch carried by the mouthpiece for generating a pop-up window on the computer display based upon activation of said second switch.

21. A method according to claim 17 wherein the mouth-operated computer input device communicates with the computer display cursor via a wired connection.

22. A method according to claim 17 wherein the mouth-operated computer input device communicates with the computer display cursor via a wireless connection.
