Abstract
A method includes transmitting, by a plurality of drive sense circuits of a primary interactive display device, a plurality of signals on a plurality of electrodes of the primary interactive display device. At least one change in electrical characteristics of a set of electrodes is detected by a set of drive sense circuits during a temporal period. A stream of user notion data is determined by a processing module of the primary interactive display device based on interpreting the at least one change in the electrical characteristics of the set of electrodes during the temporal period. The stream of user notation data is displayed via a display of the primary interactive display device during the temporal period. The stream of user notation data is transmitted, via a network interface of the primary interactive display device, to a plurality of secondary interactive display devices for display.
