Devices and method for manipulating user interfaces with stylus and non-stylus contacts

Abstract:

An electronic device with a touch-sensitive display and one or more sensors to detect signals from a stylus associated with the device displays a user interface in a viewing mode, the user interface including a content region and a first control region. While displaying the user interface in the viewing mode, the device detects an input by a first contact on the touch-sensitive display; and, in response to detecting the input: when the first contact is a stylus contact in the content region, the device displays, in the content region, a mark drawn in accordance with movement of the first contact in the input. If the first contact is a non-stylus contact in the content region, the device performs a navigation operation in the content region in accordance with movement of the first contact without displaying the mark that corresponds to the first contact in the content region.
