Claim 14:
15. A computing device comprising:
one or more conductive layers that is implemented for a touch sensor and a common portion, wherein the one or more conductive layers are implemented on a same plane, wherein the touch sensor includes a plurality of segments that are electrically connected, wherein the common portion is implemented for another touch sensor;
a drive-sense circuit (DSC) operably coupled to the touch sensor, wherein, when enabled, the DSC configured to:
generate a signal based on a reference signal;
provide the signal to the touch sensor via a single line and simultaneously to sense the signal via the single line, wherein an electrical characteristic of the touch sensor affects the signal; and
generate a digital signal representative of an effect on the signal based on the electrical characteristic of the touch sensor;

another DSC operably coupled to the another touch sensor, wherein, when enabled, the another DSC configured to:
generate another signal based on another reference signal;
provide the another signal to the another touch sensor via another single line and simultaneously to sense the another signal via the another single line, wherein another electrical characteristic of the another touch sensor affects the another signal; and
generate another digital signal representative of another effect on the signal based on the another electrical characteristic of the another touch sensor;

memory that stores operational instructions; and
one or more processing modules operably coupled to the DSC and the memory, wherein, when enabled, the one or more processing modules is configured to execute the operational instructions to:
process the digital signal to determine the electrical characteristic of the touch sensor;
process the electrical characteristic of the touch sensor to detect interaction of a user with the touch sensor;
process the another digital signal to determine the another electrical characteristic of the another touch sensor; and
process the another electrical characteristic of the another touch sensor to detect presence of the user within a detectable proximity of the computing device.
