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 processing system. 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.
