TOUCH SENSITIVE CONTROL SYSTEM FOR NON-ELECTRONIC DISPLAY SUBSTRATE SURFACES

The touch sensitive system comprises at least one electrically active layer having at least one electrical property and configured to be applied to the substrate and an electronic controller. The electrically conductive active layer is configured to have an electrical connection with the electronic controller wherein a differentiated touch on the substrate disrupts the electrical property of the electrically active layer; and wherein the disruption is detected by the electronic controller to provide a control signal. The differentiated touch is selected from: one or more of multiple sequential touches, and/or one or more touches of extended duration.
