Abstract

A method includes identifying a value of at least one parameter of a portable electronic device. A touch threshold is modified based on the value of the at least one parameter, yielding a modified touch threshold. A touch is detected on a touch-sensitive device and a first function is performed when the touch meets the modified touch threshold.

Claims

1. A method comprising:

identifying a value of at least one parameter of a portable electronic device;

modifying a touch threshold based on the at least one parameter, yielding a modified touch threshold;

detecting a touch on a touch-sensitive device;

performing a function when the touch meets the modified touch threshold.

2. The method of claim 1, wherein the value of the at least one parameter is determined from a touch detected by the touch-sensitive device.

3. The method of claim 1, wherein performing the function comprises providing tactile feedback.

4. The method of claim 1, wherein the at least one parameter comprises at least one of a touch parameter, a function parameter, an ambient parameter, and a user parameter.

5. The method of claim 1, wherein a force value is associated with the touch threshold.

6. The method of claim 5, wherein modifying the touch threshold comprises increasing the force value associated with the touch threshold.

7. The method of claim 1, wherein modifying the touch threshold occurs after detecting the touch.

8. The method of claim 1, wherein modifying the touch threshold comprises repeatedly modifying the touch threshold.

9. A computer-readable medium having computer-readable code executable by at least one processor of a portable electronic device to perform the method of claim 1.

10. An electronic device comprising:

a touch-sensitive device;

a processor configured to;

identify a value of at least one parameter of the portable electronic device;

modify a touch threshold based on the at least one parameter to yield a modified touch threshold;

detect a touch on the touch-sensitive device;

perform a first function when the touch meets the modified touch threshold.

11. The electronic device of claim 10, further comprising an actuator configured to provide tactile feedback when the touch meets the modified touch threshold.

12. The electronic device of claim 10, wherein the processor is further configured to modify a second touch threshold associated with a second function that is performed when the touch meets the second touch threshold.

13. The electronic device of claim 10, further comprising a force sensor configured to provide a force value related to the touch.

14. The electronic device of claim 10, wherein the touch-sensitive device is disposed in a housing and is moveable with respect to the housing.

15. The electronic device of claim 14, wherein the touch-sensitive device comprises a touch-sensitive display.

16. The electronic device of claim 10, wherein the processor repeatedly modifies the touch threshold.

17. A method comprising:

detecting a touch on a touch-sensitive device;

identifying a value of at least one parameter of the touch;

modifying a touch threshold based on the value of the at least one parameter, yielding a modified touch threshold;

performing a function when the value meets the modified touch threshold.

18. The method of claim 17, wherein the at least one parameter comprises at least one of a force, an acceleration, a period, a rate, a location, and an area.
