Abstract

A universal display keyboard can include a plurality of keys whose identifying indicia can be altered via electronically-alterable displays associated with the keys. In one embodiment, indicia associated with character and function keys can be controlled by the currently active application of an electronic device external to the keyboard. The keyboard can also include a plurality of user-operable mode-changing keys or elements to select state changes for the plurality of character and function keys. The keyboard can optionally include one or more built-in display windows to show the user helpful information about the keys or to provide application menu information. Various methods, as well as application of the keyboard to a keyboard system and to a data processing system, are also described.

Claims

1. A keyboard comprising:

a plurality of keys;

one or more electronically-alterable displays associated with the keys to display identifying indicia corresponding to such keys; and

a controller coupled to the one or more electronically-alterable displays, the controller to receive control code from an application executing on an external electronic device, the controller to control the display of the identifying indicia in accordance with the control code.

2. The keyboard recited in claim 1 and further comprising:

at least one user-operable mode-changing element to make a state change to the one or more electronically-alterable displays, the at least one user-operable mode-changing element being selected from the group consisting of a mode-changing key, a combination of two or more mode-changing keys, and a voice recognition system.

3. The keyboard recited in claim 2, wherein the combination of two or more mode-changing keys comprises 2⁵ unique combinations operable by ones of the four fingers and thumb on one hand of a keyboard user.

4. The keyboard recited in claim 1 and further comprising:

a state display to display information.

5. The keyboard recited in claim 4, wherein the state display is selected from the group consisting of a liquid crystal display, a light-emitting diode, and a flat panel display.

6. The keyboard recited in claim 4, wherein the controller is further coupled to the state display, wherein the controller is to receive control code from the application executing on the external electronic device, and wherein the controller is to control the information displayed by the state display in accordance with the control code.

7. The keyboard recited in claim 1, wherein the plurality of keys comprise character and function keys.

8. A keyboard system comprising:

a keyboard having a plurality of keys;

one or more electronically-alterable displays on the keyboard associated with the keys to provide identifying indicia corresponding to such keys;

a controller coupled to the one or more electronically-alterable displays, the controller to receive control code from an application executing on an external electronic device, the controller to control the display of the identifying indicia in accordance with the control code; and

at least one user-operable mode-changing element coupled to the keyboard to make a state change to the one or more electronically-alterable displays.

9. The keyboard system recited in claim 8 and further comprising:

a memory coupled to the controller to store machine-accessible information and data, including a plurality of key states.

10. The keyboard system recited in claim 8, wherein the mode-changing element is one of a mode-changing key, a combination of two or more mode-changing keys, at least one button on a pointing device, a foot pedal, and a voice recognition system.

11. The keyboard system recited in claim 10, wherein the combination of two or more mode-changing keys comprises 2⁵ unique combinations operable by ones of the four fingers and thumb on one hand of a keyboard user.

12. The keyboard system recited in claim 8, wherein the plurality of keys comprise character and function keys.

13. The keyboard system recited in claim 8 and further comprising:

a state display on the keyboard to display a state of the character and function keys.

14. The keyboard system recited in claim 13, wherein the controller is to receive control code from the application, and wherein the controller is to control the information displayed by the state display in accordance with the control code.

15. The keyboard system recited in claim 13, wherein the state display is selected from the group consisting of a liquid crystal display, a light-emitting diode, and a flat panel display.

16. A data processing system comprising:

a computer to execute an application; and

a keyboard system including

a keyboard having a plurality of keys;

one or more electronically-alterable displays on the keyboard associated with the keys to provide identifying indicia corresponding to such keys; and

a controller coupled to the one or more electronically-alterable displays and to the computer to receive control code, the controller to control the display of the identifying indicia in accordance with the control code.

17. The data processing system recited in claim 16, and further comprising at least one user-operable mode-changing element to make a state change to the one or more electronically-alterable displays.

18. The data processing system recited in claim 17, wherein the mode-changing element is selected from the group consisting of a mode-changing key, a combination of two or more mode-changing keys, at least one button on a pointing device, a foot pedal, and a voice recognition system.

19. The data processing system recited in claim 18, wherein the combination of two or more mode-changing keys comprises 2⁵ unique combinations operable by ones of the four fingers and thumb on one hand of a keyboard user.

20. The data processing system recited in claim 18, wherein the foot pedal comprises at least one mode switch.

21. The data processing system recited in claim 16 and further comprising:

a state display to display information.

22. The data processing system recited in claim 21, wherein the controller is to further receive control code from the application, the controller to control the information displayed by the state display in accordance with the control code.

23. The data processing system recited in claim 21, wherein the state display is selected from the group consisting of a liquid crystal display, a light-emitting diode, and a flat panel display.

24. A method comprising:

providing identifying indicia on a plurality of keys of a keyboard using one or more electronically-alterable displays physically associated with the keys; and

making a state change in the one or more electronically-alterable displays in response to control code from an executing application.

25. The method recited in claim 24 and further comprising:

making a state change in the one or more electronically-alterable displays by operating a mode-changing element selected from the group consisting of a mode-changing key, a combination of two or more mode-changing keys, at least one button on a pointing device, a foot pedal, and a voice recognition system.

26. The method recited in claim 25 wherein, in making, the combination of two or more mode-changing keys comprises 2⁵ unique combinations and such combinations are made by ones of the four fingers and thumb on one hand of a human keyboard user.

27. The method recited in claim 24 and further comprising:

displaying a state of the keys on a state display.
