CPC G06F 3/0445 (2019.05) [G06F 3/016 (2013.01)] | 20 Claims |
1. A touch sensor device (TSD) comprising:
a plurality of TSD electrodes associated with a surface of the TSD, wherein a 3-D object that includes one or more marker electrodes also being associated with a region of the surface of the TSD;
a plurality of drive-sense circuits (DSCs) operably coupled to the plurality of TSD electrodes, wherein, when enabled, a DSC of the plurality of DSCs is configured to service a TSD electrode and to generate a digital signal that is representative of a change of impedance of the TSD electrode caused by capacitive coupling between the TSD electrode and the one or more marker electrodes;
memory that stores operational instructions; and
one or more processing modules operably coupled to the plurality of DSCs and the memory, wherein, when enabled, the one or more processing modules is configured to execute the operational instructions to:
determine the region of the surface of the TSD that is associated with the 3-D object based on the digital signal; and
adapt sensitivity of the TSD within the region of the surface of the TSD that is associated with the 3-D object differently than a remaining portion of the TSD not included with the region of the surface of the TSD that is associated with the 3-D object.
