Abstract:
An electronic device with a touch-sensitive surface and a display displays a control for controlling a parameter associated with respective content. The device detects a gesture on the touch-sensitive surface for adjusting the parameter, and in response to detecting the gesture, the device determines an adjustment of the parameter that corresponds to an extent of the gesture. When the adjustment of the parameter would cause one or more predefined adjustment limits to be exceeded, the device generates a respective tactile output on the touch-sensitive surface, and when the adjustment of the parameter would not cause the one or more predefined adjustment limits to be exceeded, the device adjusts the parameter without generating the respective tactile output on the touch-sensitive surface.
