Abstract
The embodiments described herein provide devices and methods that facilitate improved sensor device usability. Specifically, the devices and methods provide the ability to determine more reliably that sensed object positions correspond to a single input object or multiple input objects. For example, the devices and methods may be used to determine if a first sensed object position and a second sensed object position correspond to a single input object. The determination of a single input object or multiple input objects may be used to facilitate the reliable activation of user interface actions, such as cursor control and the use of virtual button zones, and thus can improve sensor device usability.
