A processing system includes sensor circuitry and processing circuitry. The sensor circuitry is configured to be coupled to force sensor electrodes, and is configured to drive the force sensor electrodes to obtain capacitive measurements. The processing circuitry is operatively connected to the sensor circuitry and configured to aggregate the capacitive measurements into an aggregated measurement, and apply, to the aggregated measurement, a capacitive measurement to temperature mapping to obtain a current temperature of the force sensor electrodes.

Force calibration for temperature

Grip management includes determining, using first changes of capacitance of a sensing region of an input device, a first signal level corresponding to a first input object satisfying a size threshold and being proximate to a first side of the input device at a first time, and determining a first signal level threshold based on the first signal level. The grip management further includes determining, using second changes of capacitance of the sensing region, a second signal level corresponding to the first input object being proximate to the first side of the input device at a second time, and detecting a squeeze of the input device based at least in part on the second signal level satisfying the first signal level threshold.
