Abstract: An electronic device is disclosed. The electronic device includes a first input device; a second input device capable of operating in a first operating mode; and a system management module in communication with the first input device and the second input device. The system management module is configured for switching the second input device to a second operating mode in response to detecting, by the first input device, a presence of a user without receiving any operation-specific input from the user.

Abstract: An electronic device has a touch-sensitive display and one or more touch-sensitive surfaces that are distinct from the touch-sensitive display. The device displays one or more user interface objects on the touch-sensitive display, and detects one or more user contacts on the one or more touch-sensitive surfaces. While detecting the one or more user contacts on the one or more touch-sensitive surfaces, the device also detects one or more finger contact areas at respective locations on the touch-sensitive display. For each finger contact area, the device determines a respective finger contact coordinate tuple based at least in part on: a respective location of a respective finger contact area, and the user contacts on the one or more touch-sensitive surfaces. The device manipulates at least one of the one or more user interface objects in accordance with the respective finger contact coordinate tuples.

Abstract: Methods and systems for implementing gestures with sensing devices are disclosed. More particularly, methods and systems related to gesturing with multipoint sensing devices are disclosed.
