Abstract
The invention relates to a processing system. The processing system includes a determination module configured to make a determination that a low ground mass condition associated with an input device exists in an initial combination signal obtained from a sensor module using initial sensor settings. Based on the determination, adjusted sensor settings are determined, and an adjusted combination signal is obtained, using the adjusted sensor settings and, using the adjusted combination signal, object information for one or more input objects in a sensing region of the input device is obtained. The sensor module is configured to generate, using a first sensor electrode, a second sensor electrode, and the adjusted sensor settings, the adjusted combination signal. The adjusted combination signal includes effects of a transcapacitive coupling between the first sensor electrode and the second sensor electrode and effects of an absolute capacitive coupling between the second sensor electrode and the input object.
