    Abstract: An electronic device detects, on a touch-sensitive surface, a user input directed to a user interface element associated with a respective operation, for example in a user interface for a locked mode of operation of the device. A first portion of the user input includes an increase in intensity of the contact followed by a second portion of the user input that includes a decrease in intensity of the contact. In response to the user input, the device displays a transformation of the user interface element, wherein a degree of the transformation is determined based on an intensity of the user input. If the user input satisfies feed-forward criteria, including a requirement that a characteristic intensity of the contact increase above a feed-forward intensity threshold, the device generates a first tactile output without performing the respective operation. Otherwise, the device generates a second tactile output and performs the respective operation.
