A processing system for multiple input object force estimation includes sensor circuitry and processing circuitry. The sensor circuitry is configured to acquire measurements of a sensing region using sensor electrodes. The processing circuitry is connected to the sensor circuitry. The processing system is configured to obtain a delta image of the sensing region using the measurements, identify locations of the input objects in the sensing region using the delta image, and determine a force estimate for each input object using the delta image, a bending response model, and the plurality of locations. The processing system is further configured to perform an action based on the force estimate of each input object of the plurality of input objects.

Touch force estimation

A processing system for an input device includes a sensor module and a noise mitigation module. The sensor module includes sensor circuitry and is configured to drive a plurality of transmitter electrodes with transmitter signals, and receive, with a plurality of receiver electrodes, resulting signals comprising effects corresponding to the transmitter signals. The noise mitigation module is configured to determine positional information for a first input object in a sensing region of the input device based on the resulting signals and to report the positional information. The noise mitigation module includes a touch buffer configured to store a plurality of input object states corresponding to the first input object and is configured to limit, when in a high-noise mode, the reporting of positional information based on the plurality of input object states stored in the touch buffer.
