Abstract: A capacitance sensing method may include performing a first scan of a plurality of sensor elements of a touch-sensing surface to detect a plurality of capacitance values indicating a presence of multiple contacts at the touch sensing surface. Based on the plurality of capacitance values, a plurality of coordinates may be calculated that indicate a plurality of possible contact locations for the multiple contacts. In response to detecting that the plurality of coordinates indicates the presence of the multiple contacts, a resolve scan of at least a first intersection of sensor elements may be performed, where the first intersection corresponds to at least one of the possible contact locations. Based on the resolve scan, at least one of the possible contact locations may be identified as an actual contact location of one of the multiple contacts.

Abstract: A method and apparatus receive first input through a touch screen and communicate over a first wireless network responsive to the first input. The method and apparatus receive second input through the touch screen and use the second input to control a second device through a second wireless network.

Abstract: A device includes a first wireless transceiver adapted to communicate over a cellular network, a second wireless transceiver adapted to communicate over a local network separate from the cellular network, and a mechanism adapted to report movement information to a computer via the second wireless transceiver. The mechanism is optionally an optical sensor reporting relative position information. The device is operable as both a cellular communication device and a computer pointing device. A button of the device is adapted to operate as a mouse button, and optionally, in some modes, controls operation of the cellular communication device. The second wireless transceiver optionally uses Universal Serial Bus protocol. The device optionally transfers files via the second wireless transceiver. In some usage scenarios, the device and a separate wireless pointing device communicate with a same computer and are used to operate an application, such as a gaming application.
