Event Recognition

An electronic device, while displaying application content for a first application on a touchscreen display, detects an input comprising one or more touches on a region of the touchscreen display that includes the application content of the first application. In response to detecting the input comprising the one or more touches, the electronic device, in accordance with a determination that the one or more touches correspond to a system gesture for switching applications, replaces display of the first application with a second application without delivering information corresponding to the one or more touches to the first application; and in accordance with a determination that the touches do not correspond to a system gesture, delivers the information corresponding to the one or more touches to the first application.
