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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device and host communications for input/output (I/O) operative touch sensor device (TSD)","description":"A touch sensor device (TSD) includes TSD electrodes associated with a surface of the TSD.
