Hybrid baseline management

Abstract:

A processing system for force baseline management includes sensor circuitry configured to obtain capacitive sensing signals of a sensing region from sensor electrodes, and processing circuitry coupled to the sensor circuitry and configured to determine, from the capacitive sensing signals, force measurements and touch measurements. The processing circuitry is further configured to modify a force baseline at a decreased rate in response to determining a presence of an input object using the force measurements and an absence of the input object using the touch measurements.
