Abstract (en)

[origin: WO9819283A1] A new touch screen based upon the mapping of coordinates from an equipotential (32) space defined by a simple set of screen electrodes to some other more useful coordinates, such as Cartesian. The key idea is that unique coordinate mapping can be achieved with each sensing pair of electronic readings.
