Cirque’s GlidePoint® touch panels contain a grid of vertical and horizontal electrodes which are connected to a sophisticated full-custom mixed signal integrated circuit (IC) mounted on the touch panel’s reverse side. “Mutual capacitance” from each of the horizontal electrodes to each of the vertical electrodes is continually measured by the IC. A person’s finger near the surface of the touch panel alters the mutual capacitance between the vertical and horizontal electrodes. The position of the finger’s centroid is precisely determined based upon changes in mutual capacitance as the finger moves across the touch panel’s surface.
