Claim:
A method for operating an on-screen keyboard, the method comprising: providing a transparent arrangement of sensing conductors located on an electronic display screen for detecting one or more finger touches when present, the transparent arrangement including a first and second set of conductor lines forming a grid across the electronic display screen with a plurality of junctions there between at which the conductor lines do not contact; providing a signal to a plurality of conductor lines of the first set of conductor lines; detecting output arising from one or more finger touches when present, wherein the output arising from each of the one or more finger touches is detected from at least one conductor line of the second set of conductor lines in response to the signal provided to the at least one conductor line of the first set of conductor lines; detecting positions of the one or more finger touches on the transparent arrangement responsive to the output detected; and associating the positions of the one or more finger touches on the transparent arrangement to positions of one or more keys of a keyboard displayed on the electronic display screen.
