Abstract: A method of launching computer commands and programs on a personal digital assistance (PDA) includes sticking a molded membrane having elevated portions serving as emulated mechanical buttons over a touch sensitive screen that is in part disposed over a display with the mechanical buttons placed juxtaposed respective virtual buttons shown on the display, so that, upon pressing a portion of the membrane generates X-Y voltage levels corresponding to touch screen X-Y coordinates that are in turn associated with virtual button corresponding to computer commands and programs that are launched. The pressing of the emulated mechanical button offers stylus-free operation of the PDA.

Abstract: 1) A personal digital assistance (PDA) has a command bar made from a stick-on molded membrane having elevated portions serving as emulated mechanical buttons disposed over a touch sensitive screen that is in part disposed over a display with the mechanical buttons placed juxtaposed respective virtual buttons shown on the display, so that, upon pressing a portion of the membrane generates X-Y voltage levels corresponding to touch screen X-Y coordinates that are in turn associated with virtual button corresponding to computer commands and programs that are launched. The pressing of the emulated mechanical button offers stylus-free operation of the PDA.

Abstract: A personal digital assistance (PDA) has a graffiti area upon which a stick-on molded membrane having elevated portions serving as an emulated mechanical cursor button and mouse button that are disposed over a touch sensitive screen with a cursor being displayed upon a display, so that, upon pressing the cursor button, the display cursor moves about the display and onto virtual buttons or icons corresponding to computer commands and programs that are launched when the mouse button is pressed. Portions of the membrane over the graffiti area generates X-Y voltage levels corresponding to touch screen X-Y coordinates that are in turn associated with cursor button and mouse button for emulating a mouse function on the PDS The pressing of the emulated mechanical buttons offers stylus-free emulated mouse operation of the PDA.
