Baseline management for sensing device

A method for baseline management for a capacitive sensing device, comprising:

• obtaining a first profile from sensing signals received with a plurality of sensor electrodes of the capacitance sensing input device;
• calculating, using the first profile, a first statistic and a second statistic for the first profile;
• selecting, 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;
• and
• adjusting a baseline for the capacitance sensing input device according to the selected baseline relaxation technique.

An input device comprising:

• a plurality of sensor electrodes configured to receive sensing signals;
• and
• a processing system operatively connected to the plurality of sensor electrodes and configured to:
• obtain a profile from the resulting signals;
• calculate, using the profile, a first statistic and a second statistic for the profile;
• 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;
• and
• adjust a baseline for the capacitance sensing input device according to the selected baseline relaxation technique.
