Abstract: A capacitance module may include a set of electrodes, a processor in communication with the set of electrodes and memory in communication with the processor. The memory may include programmed instructions that cause the capacitance module, when executed, to perform a calibration, the calibration including prompting a press input, storing a press attribute of a press measurement associated with the press input, and determining a type of unprompted input by consulting the stored press attribute.
