A resistive touch screen includes a transparent substrate defining a touch area; a first layer of conductive material formed on the transparent substrate and extending over the touch area; an electrical connection to the first layer of conductive material; a transparent flexible cover sheet; a second layer of conductive material formed on the transparent flexible cover sheet, the cover sheet being mounted in a spaced apart relationship from the substrate, whereby a touch in the touch area results in an a electrical contact between the first and second layers of conductive material at the point of touch; an electrical connection to the second layer of conductive material; and at least one of the first or second layers of conductive material having a variable conductivity.
