A touch screen capable of correctly identifying multiple touches employs multiple active line arrays oriented to provide multi-dimensional data. Three arrays of capacitance based active lines are each distinctly oriented to form a plurality of intersections. A first and second array are generally oriented perpendicularly while a third array is oriented to bisect the resulting matrix such that the active lines of the third array also intersect the existing vertices. As a result of a touch each active line array identifies the location of the touch from three distinct directions. Ambiguity from dual touch scenarios existing in dual array systems is removed by providing an additional reference.
