1. A method comprising:
- determining a touch value based on a touch applied to a touch-sensitive sensor;
determining an elapsed time that the touch value initially exceeds a first threshold value, the first threshold value associated with a push event;
setting a second threshold value of the touch-sensitive sensor based on the elapsed time, the second threshold value associated with a release event;
selecting a haptic feedback response based on the elapsed time; and
generating an output signal indicative of the haptic feedback response.

Abstract
A system and method for setting threshold values based on an amount and selecting a haptic feedback response. The method comprises determining a touch value based on a touch applied to a touch-sensitive sensor. The method further comprises determining an amount that the touch value exceeds a first threshold value. The method further comprises setting a second threshold value based, at least in part on the amount. The method further comprising selecting a haptic feedback response that can be based at least in part on the amount.

18. An electronic device comprising:
-
a touch-sensitive interface configured to detect a touch on a surface of the touch-sensitive interface; a memory; and a processing unit in communication with the memory and the touch-sensitive interface, the processing unit configured to; determine a touch value based on the touch applied to the touch-sensitive sensor; determine an amount that the touch value initially exceeds a first threshold value, the first threshold value being associated with a push event; set a second threshold value of the touch-sensitive interface based on the amount the second threshold value associated with a release event; select a haptic feedback response based on the amount; and generate an output signal indicative of the haptic feedback response. - View Dependent Claims (19, 20, 21, 22, 23)
