First Claim
1. An electronic system comprising:
- a capacitive input device comprising;
an input surface configured to rotate about a first axis, anda first force sensor configured to sense a force applied to the input surface;
a processing system communicatively coupled to the capacitive input device, the processing system configured to;
determine positional information for each of at least one input object in contact with the input surface;
receive a force measurement from the first force sensor;
determine a force measurement for a first input object of the at least one input objects based upon a position of the first input object, the force measurement from the first force sensor and a location of the first force sensor relative to the first axis; and
determine a type of user input based upon the determined force measurement for the at least one input object.

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.
