    Abstract: A touch sensor method and device are described that allow one or more simultaneous touches to be sensed and mapped to Cartesian coordinates. The device utilizes closely spaced multiple conducting strips to provide digital location of a touch position according to the position strip and analog location along the length of the strip. When the strips are energized individually and in coordinated ways, multiple touches are individually sensed and their positions are reported.
