Disclosed is the use of Visage@, a commercial touch system technology using force sensors, for implementing touch capability on the video display of an electrophotographic-printing machine User Interface (UI). Replacing button-capped switches located below the UI with pseudo buttons (graphic representations, button shaped projections or mechanical switches having no electronics) and programming the touch system that there are touch points below the UI carries out the implementation. Whenever a user touches one of the pseudo buttons, the system registers the transaction as a switch depression. Connecting all the buttons together in parallel provides a signal on a single set of interconnecting wires when any button is actuated. The signal is presented to the touch system for determination of which button was pressed with improved actuation speed. Placing the force sensors behind a Liquid Crystal Display (LCD) or an edit pad creates an invisible touch panel.
