Abstract
Increasing ground mass state of an input device is disclosed. Increasing the ground mass state includes driving sensor electrodes to acquire first measurements of a sensing region of the input device, and driving a first subset of the sensor electrodes while a second subset is coupled to device ground to acquire second measurements of a portion of the sensing region. Increasing the ground mass state further includes determining a location of an input object in the sensing region using the first measurements, determining the second subset corresponds to the location of the first input object in the sensing region, and coupling the second subset to device ground when driving the first subset in response to the second subset corresponding to the location of the first input object.
