Abstract

A hand recognition system.

Claims

1. A display comprising:

(a) said display including light sensitive elements within the area illuminated by said display;

(b) a processing device receiving information from said light sensitive elements responsive to said light sensitive elements sensing a portion of a hand;

(c) said processing device determining whether said portion of said hand matches a known hand;

(d) wherein said portion of said hand includes at least two fingers of said hand.

2. The display of claim 1 wherein said known hand is characterized by a template.

3. The display of claim 1 wherein said light sensitive elements are photo-transistors.

4. The display of claim 1 wherein said display is portable.

5. The display of claim 1 wherein said processing device is within a housing surrounding said display.

6. The display of claim 1 wherein said processing device is a laptop computer.

7. The display of claim 1 wherein said processing device is a personal computer.

8. The display of claim 1 further comprising a first light source external to said display and illuminating said display.

9. The display of claim 8 further comprising a second light source external to said display and illuminating said display.

10. The display of claim 8 wherein said first light source selectively illuminates said display.

11. The display of claim 10 wherein said selective illumination increases the ability to sense said portion of said hand.

12. The display of claim 11 wherein said selective illumination increases the contract of said display.

13. The display of claim 8 wherein said processing device determines 3-dimensional characteristics of said portion of said hand.

14. The display of claim 1 wherein said display is a liquid crystal device.

15. A computer comprising:

(a) a housing enclosing said computer;

(b) a display movably connected to said housing and operationally connected to said computer;

(c) said display including light sensitive elements within the area illuminated by said display;

(d) selectively permitting access to an associated system based upon sensing at least a portion of a hand by said light sensitive elements;

(e) wherein said portion of said hand includes at least two fingers of said hand.

16. The computer of claim 15 wherein said display is a liquid crystal device.

17. The computer of claim 15 wherein said housing is portable.

18. The computer of claim 15 wherein said hand is characterized by a template.

19. The computer of claim 15 wherein said light sensitive elements are photo-transistors.

20. The computer of claim 15 wherein said computer is a laptop computer.

21. The computer of claim 15 wherein said computer is a personal computer.

22. The computer of claim 15 further comprising a first light source external to said display and illuminating said display.

23. The computer of claim 22 further comprising a second light source external to said display and illuminating said display.

24. The computer of claim 22 wherein said first light source selectively illuminates said display.

25. The computer of claim 24 wherein said selective illumination increases the ability to sense said portion of said hand.

26. The computer of claim 25 wherein said selective illumination increases the contract of said display.

27. The computer of claim 15 wherein said processing device determines 3-dimensional characteristics of said portion of said hand.

28. The computer of claim 15 wherein said display is a liquid crystal device.

29. The computer of claim 15 wherein said display includes a set of photo-transistors between a front surface and a light valve.

30. A hand recognition system comprising:

(a) a display;

(b) a sensing system for sensing at least a portion of a hand;

(c) said display indicating to a user of said hand recognition system the following;

(i) an identification that said display is used for hand recognition;

(ii) an indication of where to locate said hand for said hand recognition system;

(iii) an indication of the results of sensing said at least a portion of said hand by said hand recognition system;

(d) wherein said portion of said hand includes at least two fingers of said hand.

31. The hand recognition system of claim 30 wherein said sensing system includes light sensitive elements within said display.

32. The hand recognition system of claim 31 wherein said light sensitive elements sense at least a portion of said hand.

33. A computer comprising:

(a) a housing enclosing said computer;

(b) a display movably connected to said housing and operationally connected to said computer;

(c) said display including light sensitive elements within the area illuminated by said display;

(d) selectively permitting access to an associated system based upon sensing at least a portion of a hand by said light sensitive elements;

(e) wherein said display includes a set of photo-transistors between a front surface and a light valve.
