Tactile indicator which changes the texture of a surface for a portable electronic device

1. A method comprising:

determining a status associated with a function of a portable electronic device; and

actuating a tactile status indicator to change a texture at a surface of the portable electronic device for a period of time to indicate the status;

wherein the status is tactilely indicated as a level on a gauge.

2. A method as claimed in claim 1 , wherein the surface is part of a housing of the portable electronic device.

3. A method as claimed in claim 1 , wherein the surface is part of a housing of an accessory.

4. A method as claimed in claim 1 , wherein the function is one of: communication with a wireless network, powering the portable electronic device, volume control of the portable electronic device and a device application.

5. A method as claimed in claim 4 , wherein when the function is the volume control of the portable electronic device, adjusting a volume in response to a user input.

6. A method as claimed in claim 1 , wherein the status is indicated in response to a user input.

7. A method as claimed in claim 6 , wherein the user input is a touch near the tactile status indicator.

8. A method as claimed in claim 1 , wherein a flexible membrane covers the surface to hide the tactile status indicator.

9. A method as claimed in claim 1 , wherein the period of time is when a telephone application is active.

10. A method as claimed in claim 1 , wherein the period of time begins when the status is determined and ends when there is a change in the status.

11. A method as claimed in claim 1 , wherein the status of the function of the portable electronic device is determined when there is a change in the device function.

12. A computer-readable medium comprising instructions executable on a processor of an electronic device for implementing the method of claim 1 .

13. A portable electronic device comprising:

a housing;

a processor for executing a program stored in memory to determine a status associated with a function of the portable electronic device; and

a tactile status indicator to change a texture at a surface of the housing for a period of time to indicate the status;

wherein the status is tactilely indicated as a level on a gauge.

14. A portable electronic device as claimed in claim 13 , wherein the tactile status indicator is actuated in response to a user touch.

15. A portable electronic device as claimed in claim 13 , wherein the function is one of: communication with a wireless network, powering the portable electronic device, volume control of the portable electronic device and a device application.

16. A tactile status indicator of a portable electronic device, the tactile status indicator comprising:

a projection movable relative to a housing of the portable electronic device, the projection being at least partly aligned with an opening of the housing;

a driving mechanism for moving the projection to change a texture at the surface of the portable electronic device for a period of time to indicate a status of a function of the portable electronic device;

wherein the status is tactilely indicated as a level on a gauge.

17. A tactile status indicator as claimed in claim 16 , wherein the driving mechanism is one of: a solenoid switch, an electromechanical cam and a hydraulic pump.

18. A tactile status indicator as claimed in claim 16 , comprising more than one projection.

19. A tactile status indicator as claimed in claim 16 , wherein the function is one of: communication with a wireless network, powering the portable electronic device, volume control of the portable electronic device and a device application.

20. A tactile status indicator as claimed in claim 16 , wherein when the function is the volume control of the portable electronic device, a volume is adjustable in response to a user input.
