8. ) A method of operating a self-service terminal utilizing a tactile navigation apparatus attached to a touch-screen display, the method comprising:
- receiving pressure to a first embossed symbol on the tactile navigation apparatus where the embossing of the first embossed symbol is identifiable by touch;
deflecting the first embossed symbol reducing the distance between an electrically conductive material located under the first embossed symbol and the surface of the touch-screen display;
after deflecting the electronically conductive material, causing the capacitance of a first portion of the touch-screen display proximate to the electronically conductive material to change; and
detecting the change in capacitance to the first portion of the touch-screen display and generating a first signal indicating a first location on the display corresponding to the location of the first portion.

16. ) A system for improving accessibility to a self-service terminal, the system comprising:
-
a self-service terminal including a touch-screen display; a tactile navigation apparatus attached to the touch surface of the touch-screen display, the apparatus comprising; a flexible multilayer material comprising; a top graphical layer where graphics representing one or more symbols are printed and embossed on the layer where the one or more symbols are identifiable by touch; a circuit layer located below the graphical layer, the circuit layer including an electrically conductive material attached to the lower side of the circuit layer; a spacer layer located below the circuit layer where the spacer layer has a spacer material in a first area and has no spacer material in a second area that is generally underneath each of the one or more symbols; and an adhesive layer located below the spacer layer and having the same pattern as the spacer layer where the adhesive layer adheres to the touch surface of the touch-screen display when the apparatus is attached to the touch-screen display. - View Dependent Claims (1, 2, 3, 4, 5, 6, 7, 17, 19, 20, 21)
