Abstract
A method for using a touch display system comprises defining local distortion zones within regions of a touchscreen. Each of the local distortion zones has an associated calibration touch point and a target. Coordinates of a user touch point are distorted within a first local distortion zone based on a location of the user touch point within the first local distortion zone.
