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.
