Abstract

An overlay includes a sheet corresponding to a plurality of keys that are associated with an application for a portable electronic device. An identifier is associated with the application. The identifier is identifiable by the portable electronic device, such that the application is opened upon identification of the identifier.

Claims

1. An overlay comprising:

a sheet corresponding to a plurality of keys associated with an application for a portable electronic device;

an identifier associated with the application, wherein the identifier is identifiable by the portable electronic device, such that the application is opened upon identification of the identifier.

2. The overlay of claim 1, wherein the identifier comprises a plurality of sections, wherein each section has one of at least two different thicknesses, wherein a touch-sensitive display detects a different capacitance for each different thickness when touched, and wherein when at least one touch is detected along the plurality of sections, the application is identified.

3. The overlay of claim 1, wherein the identifier comprises a plurality of magnets disposed in a plurality of first locations on the sheet, and wherein the plurality of first locations are aligned with a plurality of second locations on the portable electronic device.

4. The overlay of claim 3, wherein each of the plurality of magnets is disposed in one of at least two different orientations.

5. The overlay of claim 3, wherein the at least two different orientations comprise magnetic north and magnetic south.

6. The overlay of claim 3, wherein the plurality of magnets hold the overlay in position with respect to the plurality of keys.

7. The overlay of claim 1, wherein the identifier comprises a visual indicator.

8. The overlay of claim 7, wherein the visual indicator comprises a bar code.

9. The overlay of claim 7, wherein the visual indicator comprises a camera-readable shape disposed in the sheet.

10. The overlay of claim 7, wherein the visual indicator comprises a translucent colored segment disposed in the sheet.

11. The overlay of claim 1, further comprising at least one tactile identification related to the application.

12. The overlay of claim 1, wherein the plurality of keys comprises mechanical keys or images displayed on a touch-sensitive display.

13. A method comprising:

receiving, by a portable electronic device, a first overlay for a plurality of keys, wherein the first overlay corresponds to a first of a plurality of applications that run on the portable electronic device;

identifying a first identifier associated with the first overlay;

determining which of the plurality of applications is associated with the first identifier, yielding a first identified application;

opening the first identified application on the portable electronic device.

14. The method of claim 13, wherein identifying comprises reading a tactile barcode disposed on the first overlay by detecting at least one touch along the tactile barcode.

15. The method of claim 13, wherein a unique set of capacitance values is associated with each of a plurality of overlays, and wherein identifying the first identifier comprises detecting a first set of capacitance values from touches detected on a touch-sensitive display.

16. The method of claim 13, further comprising:

detecting a touch on each of a plurality of sections of the first overlay;

identifying a capacitance value for each of the plurality of sections, yielding a first set of capacitance values;

determining the first application from the first set of capacitance values.

17. The method of claim 13, further comprising:

identifying a capacitance value for each of a plurality of touches on a touch-sensitive display, yielding a first set of capacitance values;

determining the first application from the set of capacitance values.

18. The method of claim 13, further comprising:

receiving, by a portable electronic device, a second overlay, wherein the second overlay corresponds to a second of the plurality of applications;

identifying a second identifier associated with the second overlay;

determining which of the plurality of applications is associated with the second identifier, yielding a second identified application;

opening the second identified application on the portable electronic device.

19. The method of claim 13, wherein identifying comprises ascertaining an orientation for each of a plurality of magnets aligned with the portable electronic device, yielding a set of magnet orientations.

20. The method of claim 19, wherein determining comprises ascertaining which of the plurality of applications is associated with the set of magnet orientations.

21. A computer-readable medium having computer-readable code embodied therein, the computer-readable code executable by a processor of a portable electronic device to perform the method of claim 13.

22. An overlay comprising:

a sheet corresponding to a plurality of keys associated with an application for a portable electronic device;

a tactile barcode associated with the application, wherein the portable electronic device detects at least two touch values from at least one touch along the tactile barcode and associates the at least two touch values with the application, such that the application is opened upon detection of the at least two touch values.

23. The overlay of claim 22, wherein the tactile barcode comprises a plurality of sections, wherein each section has one of at least two different thicknesses, wherein a touch-sensitive display detects a different capacitance for each different thickness when a touch is detected, and wherein the at least two touch values comprise capacitance values for each of the plurality of sections.

24. The overlay of claim 22, wherein the plurality of keys comprises mechanical keys or images displayed on a touch-sensitive display.

25. A method comprising:

receiving, by a portable electronic device, an overlay for a plurality of keys, wherein the overlay corresponds to a first of a plurality of applications that run on the portable electronic device;

reading a tactile barcode associated with the overlay, yielding a set of touch values;

determining which of the plurality of applications is associated with the set of touch values, yielding an identified application;

opening the identified application on the portable electronic device.

26. The method of claim 25, wherein reading comprises detecting at least one touch along the tactile barcode.

27. The method of claim 25, wherein reading comprises detecting at least one touch along a plurality of sections of the tactile barcode and identifying a capacitance value for each of the plurality of sections, thereby yielding the set of touch values.

28. The method of claim 25, wherein a unique set of touch values is associated with each of a plurality of overlays.

29. A computer-readable medium having computer-readable code embodied therein, the computer-readable code executable by a processor of the portable electronic device to perform the method of claim 25.

30. A portable electronic device comprising:

a plurality of keys;

a plurality of sensors arranged and constructed to identify an identifier associated with an overlay;

a processor arranged and constructed to open an application associated with the identifier.
