An electronic device with a touch-sensitive surface and a display displays a user interface object on the display, detects a contact on the touch-sensitive surface, and detects a first movement of the contact across the touch-sensitive surface, the first movement corresponding to performing an operation on the user interface object, and, in response to detecting the first movement, the device performs the operation and generates a first tactile output on the touch-sensitive surface. The device also detects a second movement of the contact across the touch-sensitive surface, the second movement corresponding to reversing the operation on the user interface object, and in response to detecting the second movement, the device reverses the operation and generates a second tactile output on the touch-sensitive surface, where the second tactile output is different from the first tactile output. |
