Abstract: A touch sensor device and method is provided that facilitates improved device usability. Specifically, the touch screen device and method provide user interface functionality while reducing the possibility of inadvertent activation of certain functions. The touch screen device comprises a proximity sensor adapted to detect object presence in a sensing region, a display screen overlapping the sensing region, and a processor. The touch screen device is adapted to provide user interface functionality by facilitating the display of user interface elements and the selection and activation of corresponding functions. For certain functions, the touch screen device and method uses the presence of a second object to confirm selection of a function before that function will be performed. So configured, the touch device screen is able to reduce the likelihood of inadvertent activation for certain functions on the device.

Abstract: A handheld communication device and method is provided that facilitates improved device usability. The handheld communication device and method uses a touch screen interface, where the touch screen comprises a proximity sensor adapted to detect object motion in a sensing region, a display screen overlapping the sensing region, and a processor. The touch screen is adapted to provide user interface functionality on the communication device by facilitating the display of user interface elements and the selection and activation of corresponding functions. The handheld communication device and method are configured to display representations of calls on the display screen, and are further configured to initiate conference calls responsive to sensed object motion beginning at a first call representation and continuing toward a second call representation. Thus, a user can initiate a conference call with a relatively simple and easy to perform gesture on the touch screen.
