Abstract

A method and system of entering data to a tablet computer can be created by displaying an image of a keyboard on a display of the computer and receiving user input through the image of the keyboard. The tablet computer preferably includes a memory unit that contains a driver for driving the display to display the image of the keyboard and a processor that runs the driver for displaying the image of the keyboard.

Claims

1. A tablet computer, said tablet computer comprising:

a display that displays an image of a keyboard, said image of said keyboard comprising images of individual keys;

a memory unit that contains a driver for driving said display to display said image of said keyboard; and

a processor that runs said driver for displaying said image of said keyboard.

2. The computer of claim 1, wherein said display comprises a touch screen display.

3. The computer of claim 2, wherein said touch screen display generates a signal in response to a user selecting one of said keys and provides said signal to said processor, wherein said signal indicates which of said keys is selected.

4. The computer of claim 1, wherein said computer further comprises a pointing device for selecting one of said keys.

5. The computer of claim 1, wherein said driver comprises a driver that selectively changes a size of said image of said keyboard.

6. The computer of claim 1, wherein said computer further comprises a control mechanism for signaling to said processor to run said driver, said control mechanism being electrically connected to said processor.

7. The computer of claim 6, wherein said control mechanism comprises an icon displayed in said display.

8. The computer of claim 6, wherein said control mechanism comprises a utility button.

9. The computer of claim 1, wherein said image of said keyboard displayed on said display uses approximately 80 percent of said display.

10. The computer of claim 1, wherein said image of said keyboard comprises an image of a number pad.

11. The computer of claim 1, wherein said image of said keyboard comprises an image of a set of function keys.

12. The computer of claim 1, wherein said display further comprises an image of a window for displaying text, said text being an echo of input through said display and said image of a keyboard.

13. The computer of claim 1, wherein said driver comprises a driver that selectively changes a size of said image of said window in response to user input.

14. The computer of claim 1, wherein said computer further comprises keyboard pads for sensing which of said keys is selected, said keyboard pads being located underneath said display, being registered with said images of said keys, and being electrically connected to said processor.

15. The computer of claim 1, wherein said computer further comprises a protective covering, said protective covering being placed over all or part of said display.

16. The computer of claim 15, wherein said covering is placed over said image of said keyboard displayed on said display.

17. The computer of claim 1, wherein said memory unit comprises a hard drive.

18. The computer of claim 1, wherein said display has a length and a width, and said driver displays said image of said keyboard oriented in a manner such that rows of said keys are aligned parallel with said length.

19. The computer of claim 1, wherein said driver comprises a function that selectively changes a size of said image of said keyboard in response to user input.

20. A method of entering data to a tablet computer, said method comprising:

displaying an image of a keyboard on a display of said computer; and

receiving user input through said image of said keyboard.

21. The method of claim 20, further comprising generating a signal in response to a user selecting a key of said keyboard and providing said signal to a processor, wherein said signal indicates which of said keys is selected.

22. The method of claim 21, further comprising selecting said key of said keyboard with a pointing device.

23. The method of claim 20, further comprising selectively changing a size of said image of said keyboard.

24. The method of claim 20, further comprising signaling to a processor to run a driver that drives said display to display said image of said keyboard.

25. The method of claim 20, further comprising selecting groups of keys of said image of said keyboard to display on said display.

26. The method of claim 20, further comprising displaying on said display an image of a window for displaying text, said text being an echo of input through said display and said image of a keyboard.

27. The method of claim 26, further comprising selectively changing a size of said image of said window.

28. The method of claim 20, further comprising sensing which keys of said keyboard are selected with keyboard pads, said keyboard pads being located underneath said display, being registered with said keys.

29. The method of claim 20, further comprising protecting all or part of said display with a protective covering.

30. The method of claim 20, wherein said display has a length and a width, said method further comprising displaying said image of said keyboard oriented such that rows of keys are aligned parallel with said length.

31. A system for entering data to a tablet computer, said system comprising:

means for displaying an image of a keyboard on a display of said computer; and

means for receiving user input through said image of said keyboard.

32. The system of claim 31, further comprising means for generating a signal in response to a user selecting a key of said keyboard and providing said signal to a processor, wherein said signal indicates which of said keys is selected.

33. The system of claim 32, further comprising means for selecting said key of said keyboard with a pointing device.

34. The system of claim 31, further comprising means for selectively changing a size of said image of said keyboard.

35. The system of claim 31, further comprising means for signaling to a processor to run a driver that drives said display to display said image of said keyboard.

36. The system of claim 31, further comprising means for selecting groups of keys of said image of said keyboard to display on said display.

37. The system of claim 31, further comprising means for displaying on said display an image of a window for displaying text, said text being an echo of input through said display and said image of a keyboard.

38. The system of claim 37, further comprising means for selectively changing a size of said image of said window.

39. The system of claim 31, further comprising means for sensing which keys of said keyboard are selected with keyboard pads, said keyboard pads being located underneath said display, being registered with said keys.

40. The system of claim 31, further comprising means for protecting all or part of said display with a protective covering.

41. The system of claim 31, wherein said display has a length and a width, said system further comprising means for displaying said image of said keyboard oriented such that rows of keys are aligned parallel with said length.

42. The system of claim 31, further comprising means for selectively changing a size of said image of said keyboard.
