Abstract

A proximity sensor device and method is provided that facilitates improved system usability. Specifically, the proximity sensor device and method provide the ability for a user to easily cause adjustments in an electronic system using a proximity sensor device as a user interface. For example, it can be used to facilitate user interface navigation, such as scrolling. As another example, it can be used to facilitate value adjustments, such as changing a device parameter. To facilitate adjustment, the embodiments of the present invention provide a proximity sensor device that is adapted to indicate adjustment in a first way responsive to object motion in both of two opposite directions along a path proximate the touch sensor device. This facilitates use of the proximity sensor device by a user to indicate adjustments to an electronic device, and is particularly useful for indicating continuing adjustments.
