Abstract:
A processing system for baseline management includes a sensor module comprising sensor circuitry coupled to sensor electrodes, where the sensor module is configured to receive resulting signals with at least a portion of the sensor electrodes. The processing system further includes a determination module operatively connected to the sensor electrodes. The determination module is configured to obtain a first profile from the resulting signals, calculate, using the first profile, a first statistic and a second statistic for the first profile, and select, according to a first range of the first statistic and a second range of the second statistic, a baseline relaxation technique from a plurality of baseline relaxation techniques to obtain a selected baseline relaxation technique. The determination module is further configured to adjust a baseline for the capacitance sensing input device according to the selected baseline relaxation technique.
