Abstract
A touch sensor device (TSD) includes TSD electrodes associated with a surface of the TSD. Also, an overlay that includes marker electrode(s) is also associated with at least a portion of the surface of the TSD. The TSD also includes drive-sense circuits (DSCs) operably coupled to the plurality of TSD electrodes. A DSC is configured to provide a TSD electrode signal to a TSD electrode and simultaneously to sense a change of the TSD electrode signal based on a change of impedance of the TSD electrode caused by capacitive coupling between the TSD electrode and the marker electrode(s) of the overlay. Processing module(s) is configured to process a digital signal generated by the DSC to determine characteristic(s) of the overlay that is associated with the at least a portion of the surface of the TSD.
