1. A method of classifying perturbations to an interface comprising a substrate supporting a conductive coating, the method comprising:
generating, using a first set of electrodes provided at a first location relative to the substrate, an electrical field;
measuring, using one or more second sets of electrodes, parameters of the electrical field at one or more second locations, each said second location being different from the first location; and
classifying a region of the interface into a specified state based on the measured parameters of the electrical field;
responsive to the specified state being indicative of a first perturbation type, disregarding the classification; and
responsive to the specified state being indicative of a second perturbation type different from the first perturbation type, sending an output signal to control electronics;
wherein the first and second perturbation types distinguish between electromagnetic interference (EMI), one or more kinds of moisture-related events, and one or more kinds of human interface interaction related events.
