1. A computing device comprising:
a touchscreen that includes a plurality of sensors and a plurality of drive-sense circuits (DSCs), wherein, when enabled, a DSC of the plurality of DSCs configured to:
generate a sensor signal based on a reference signal;
provide the sensor signal via a single line to a sensor of the plurality of sensors and simultaneously to sense the sensor signal via the single line, wherein sensing of the sensor signal includes detection of a change of the sensor signal caused by an electrical characteristic of the sensor of the plurality of sensors that includes coupling of a signal from a display of another computing device via a user into the sensor of the plurality of sensors, wherein the signal is coupled from the display of the another computing device via the user into the sensor of the plurality of sensors based on the user being in contact with or within sufficient proximity to the display of the another computing device that facilitates coupling of the signal into the user from the display of the another computing device and also based on the user being in contact with or within sufficient proximity to the touchscreen that facilitates coupling of the signal from the user into the sensor of the plurality of sensors, wherein the signal includes information corresponding to at least one of the user or an application that is operative within the another computing device;
regulate the sensor signal to match the reference signal, wherein an amount of regulation of the sensor signal is based on the change of the sensor signal caused by the electrical characteristic of the sensor of the plurality of sensors; and
generate a digital signal representative of the electrical characteristic of the sensor of the plurality of sensors;
memory that stores operational instructions; and
one or more processing modules operably coupled to the DSC, wherein, when enabled, the one or more processing modules configured to execute the operational instructions to process the digital signal representative of the electrical characteristic of the sensor of the plurality of sensors to interpret and recover the information corresponding to the at least one of the user or the application that is operative within the computing device.
