Abstract
The embodiments described herein provide devices, systems and methods that facilitate improved performance in an input device. The input device, for example, may include an input surface configured to rotate about a first axis, a proximity sensor configured to sense an input object in a sensing region proximate to the input surface of the input device, a force sensor configured to sense a force applied to the input surface of the input device, and a processing system communicatively coupled to the proximity sensor and the force sensor. The processing system may be configured to determine a position of the input object in the sensing region, and determine force information for the input object based upon the position of the input object, the force applied to the input surface, and a location of the force sensor relative to the first axis.
