Abstract

An electronic device with a display, a touch-sensitive surface, and one or more sensors to detect intensity of contacts with the touch-sensitive surface: detects, on the touch-sensitive surface, a gesture that includes an increase of intensity of a contact above a respective intensity threshold. In response to detecting the gesture: in accordance with a determination that the gesture includes a first number of contacts, the device generates a tactile output on the touch-sensitive surface; and in accordance with a determination that the gesture includes a second number of contacts different from the first number, the device forgoes generating the tactile output on the touch-sensitive surface.
