Devices, methods, and graphical user interfaces for interacting with a control object while dragging another object

An electronic device with a display, a touch-sensitive surface, and one or more sensors that detect intensities of contacts on the touch-sensitive surface displays, on the display, a user interface. While displaying the user interface, the electronic device detects an input that includes a contact on the touch-sensitive surface. In response to detecting the input while displaying the user interface, and while continuing to detect the input on the touch-sensitive surface: If an intensity of the contact satisfies an activation intensity threshold, the electronic device performs a first operation associated with the activation intensity threshold. The activation intensity threshold is determined based on whether or not prior inputs by the user on the touch-sensitive surface exceed a respective intensity threshold. If an intensity of the contact does not satisfy an activation intensity threshold, the electronic device forgoes performing the first operation associated with the activation intensity threshold.
