1. A method of operating a sensing device having a plurality of sensor electrodes, the method comprising:
- acquiring position sensor data and force sensor data using at least one of the plurality of sensor electrodes, wherein the position sensor data indicates a position of an input object in contact with the sensing device;
determining a position of the input object based at least in part on the position sensor data;
applying a jitter force filter to modify the force sensor data, wherein a weighting of the jitter force filter is based at least in part on the position of the input object; and
determining a force of the input object based on the modified force sensor data.

Abstract
An input device (100) is configured to detect force being applied to an input region (120) of the device (100) by an input object (140), in addition to the position of the input object (140) using touch sensing methods. The input device (100) applies a position-based jitter force filter to the force sensor data to compensate for a non-uniform response across the input device (100), as well as the movement of an input object (140).
