Abstract

A user input module that enables user input without the relatively high costs associated with dedicated user input mechanisms or the relatively high costs associated with handheld devices. A user input module for a device according to the present teachings includes a set of RFID tags for storing a user input and a switching mechanism for activating the RFID tags such that the RFID tags when activated transmit the user input. Devices may use RFID readers to obtain the transmitted user input and then act on the user input as appropriate.

Claims

1. A user input module, comprising:

RFID tag for storing a user input for controlling a device;

switching mechanism for activating the RFID tag, the RFID tag when activated transmitting the user input such that an RFID reader receives the user input and provides the user input to the device.

2. The user input module of claim 1, wherein the switching mechanism comprises a switch between a microcontroller and an RF antenna in the RFID tag.

3. The user input module of claim 2, wherein the switching mechanism further comprises a button positioned to activate the switch.

4. The user input module of claim 1, further comprising a set of additional RFID tags such that switching mechanism switches among activating the RFID tag and the additional RFID tags to provide the user input.

5. The user input module of claim 1, further comprising a set of additional RFID tags and corresponding switching mechanisms such that the RFID tag and the additional RFID tags transmit a chord code for the user input.

6. The user input module of claim 1, wherein the user input specifies a function associated with the device.

7. The user input module of claim 1, wherein the user input specifies a function for a user interface of the device.

8. The user input module of claim 1, wherein the user input identifies a holder of the user input module.

9. The user input module of claim 1, wherein the user input includes an account number associated with a holder of the user input module.

10. The user input module of claim 1, wherein the user input maps to a media file.

11. The user input module of claim 1, wherein the user input includes a set of profile attributes that pertain to a holder of the user input module.

12. The user input module of claim 1, wherein the user input includes a program.

13. The user input module of claim 1, wherein the user input includes a pointer to a set of information contained in a database.

14. The user input module of claim 13, wherein the information specifies a function associated with the device.

15. The user input module of claim 13, wherein the information identifies a holder of the user input module.

16. The user input module of claim 13, wherein the information includes an account number associated with a holder of the user input module.

17. The user input module of claim 13, wherein the information maps to a media file.

18. The user input module of claim 13, wherein the information includes a set of profile attributes that pertain to a holder of the user input module.

19. The user input module of claim 13, wherein the information includes a program.

20. A system, comprising:

device that performs a function in response to a user input;

user input module including a set of RFID tags for storing the user input and further including a switching mechanism for activating the RFID tags such that the RFID tags when activated transmit the user input to an RFID reader which provides the user input to the device.

21. The system of claim 20, wherein the user input specifies a function associated with the device.

22. The system of claim 20, wherein the user input specifies a function for a user interface of the device.

23. The system of claim 20, wherein the user input identifies a holder of the user input module.

24. The system of claim 20, wherein the user input includes an account number associated with a holder of the user input module.

25. The system of claim 20, wherein the user input maps to a media file.

26. The system of claim 20, wherein the user input includes a set of profile attributes that pertain to a holder of the user input module.

27. The system of claim 20, wherein the user input includes a program.

28. The system of claim 20, further comprising a database such that the user input includes a pointer to a set of information contained in the database.

29. The system of claim 28, wherein the information specifies a function associated with the device.

30. The system of claim 28, wherein the information identifies a holder of the user input module.

31. The system of claim 28, wherein the information includes an account number associated with a holder of the user input module.

32. The system of claim 28, wherein the information maps to a media file.

33. The system of claim 28, wherein the information includes a set of profile attributes that pertain to a holder of the user input module.

34. The system of claim 28, wherein the information includes a program for the device.
