Abstract
A method for calibrating a touch screen. Method may be comprised of determining an area for a region suitable for receiving, excluding activations determined to be located within a defined distance from the outer edge of the area determined for the region, accumulating a pattern of activations for a centroid within the region, and tuning a calibration factor to reposition the centroid within the center of the region.
