Abstract

The present invention can include systems and methods for expanding the functionality of user input devices. In particular, the present invention can expand the functionality of user input devices by changing the functions assigned to hardwired user input mechanisms responsive to user actuation of a function-change user input mechanism and/or responsive to automatic detection of an application change. Each hardwired user input mechanism can have an associated function indicator that visually indicates the function assigned to the hardwired user input mechanism. The present invention also can change the function indicated by the function indicators when there is a change in the functions assigned to the hardwired user input mechanisms.

Claims

1. A user input device comprising:

at least a first hardwired user input mechanism, wherein a plurality of functions are assignable thereto;

at least a first dedicated function indicator for indicating the function assigned to the first hardwired user input mechanism;

a function-change user input mechanism that transmits a function-change signal when user actuated; and

a controller configured to;

change the function assigned to the first hardwired user input mechanism responsive to the function-change signal;

change the function indicated by the first dedicated function indicator responsive to the function-change signal; and

generate one or more signals related to the function assigned to the first hardwired user input mechanism responsive to actuation thereof.

2. The user input device of claim 1, wherein the user input device comprises a remote control.

3. The user input device of claim 1, wherein the function-change user input mechanism comprises a one-dimensional switch or a multi-dimensional switch.

4. The user input device of claim 1, wherein the function-change user input mechanism comprises one or more inertial sensors.

5. The user input device of claim 1, wherein the function-change user input mechanism comprises one or more motion sensors.

6. The user input device of claim 1, wherein the first dedicated function indicator comprises multiple light sources and multiple masks, wherein the multiple masks selectively transmit light from the multiple light sources.

7. The user input device of claim 6, wherein the first dedicated function indicator further comprises a light diffuser that diffuses light from the multiple light sources.

8. The user input device of claim 6, wherein the multiple masks selectively transmit light in predetermined patterns that form text, an image, or a combination thereof.

9. The user input device of claim 1, wherein the first dedicated function indicator is disposed in close proximity to a marking that represents one or more functions.

10. The user input device of claim 1, wherein the first dedicated function indicator comprises a liquid crystal display.

11. The user input device of claim 1, wherein the controller further is configured to:

automatically detect an application change;

change the function assigned to the first hardwired user input mechanism responsive to the detected application change; and

change the function indicated by the first dedicated function indicator responsive to the detected application change.

12. A user input device comprising:

at least a first hardwired user input mechanism, wherein a plurality of functions are assignable thereto;

at least a first dedicated function indicator for indicating the function assigned to the first hardwired user input mechanism; and

a controller configured to;

automatically detect an application change;

change the function assigned to the first hardwired user input mechanism responsive to the detected application change;

change the function indicated by the first dedicated function indicator responsive to the detected application change; and

generate one or more signals related to the function assigned to the first hardwired user input mechanism responsive to actuation thereof.

13. The user input device of claim 12, wherein the user input device comprises a remote control.

14. The user input device of claim 12, wherein the application change comprises a change from one application to another application.

15. The user input device of claim 12, wherein the application change comprises a change in operating modes within a single application.

16. The user input device of claim 12, further comprising a receiver, wherein the controller is configured to detect the application change based on a signal transmitted from a remote host device to the receiver.

17. The user input device of claim 12, further comprising a function-change user input mechanism that transmits a function-change signal when user actuated, wherein the controller further is configured to:

change the function assigned to the first hardwired user input mechanism responsive to the function-change signal; and

change the function indicated by the first dedicated function indicator responsive to the function-change signal.

18. A method for expanding the functionality of a user input device, the method comprising:

detecting a function-change signal from a function-change user input mechanism;

changing the function assigned to a first hardwired user input mechanism responsive to the function-change signal;

changing the function indicated by a first dedicated function indicator responsive to the function-change signal, wherein the first dedicated function indicator indicates the function assigned to the first hardwired user input mechanism; and

generating one or more signals related to the function assigned to a first hardwired user input mechanism responsive to actuation thereof.

19. The method of claim 18, wherein detecting a function-change signal from a function-change user input mechanism comprises detecting a function-change signal from a one-dimensional switch.

20. The method of claim 18, wherein detecting a function-change signal from a function-change user input mechanism comprises detecting a function-change signal from a multi-dimensional switch.

21. The method of claim 18, further comprising selectively transmitting light from the first dedicated function indicator, wherein the light is selectively transmitted through multiple masks.

22. The method of claim 21, wherein selectively transmitting light comprises selectively transmitting light in predetermined patterns that form text, an image, or a combination thereof.

23. A method for expanding the functionality of a user input device, the method comprising:

automatically detecting an application change;

changing the function assigned to a first hardwired user input mechanism responsive to the detected application change;

changing the function indicated by a first dedicated function indicator responsive to the detected application change, wherein the first dedicated function indicator indicates the function assigned to the first hardwired user input mechanism; and

generating one or more signals related to the function assigned to a first hardwired user input mechanism responsive to actuation thereof.

24. The method of claim 23, wherein automatically detecting an application change comprises automatically detecting a change from one application to another application.

25. The method of claim 23, wherein automatically detecting an application change comprises automatically detecting a change in operating modes within a single application.

26. The method of claim 23, wherein automatically detecting an application change comprises detecting the application change based on a signal transmitted from a remote host device.
