Abstract
A capacitive sensing device is configured to detect force being applied to an input surface of the device by an input object, in addition to the position of the input object using touch sensing methods. Embodiments generate a compensation factor that is used to determine the force information in order to compensate for physical changes to the capacitive sensing device over time, air-gap non-uniform distribution, and other mechanical variations and changes.
