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 proximity sensor device and method is provided that facilitates orientation changes in displays. The proximity sensor device and method provide a user with the ability to indicate an orientation change in a display using the sensing region of a proximity sensor device as a user interface. In one specific embodiment, proximity sensor device is implemented to indicate an orientation change in a first way responsive to detected object motion along the sensing region in a first direction, and is further implemented to indicate an orientation change in a second way responsive to detected object motion along the sensing region in a second direction. Thus, a user can cause orientation changes of different ways through the use of object motions in different directions along the sensing region.
