摘要：
A method of calibrating an interactive touch system includes moving a pointer along at least one path on a touch surface over a calibration image presented on the touch surface. Pointer coordinates are generated generally continuously during the tracing representing pointer contact locations on the touch surface. The coordinate system of the touch surface is mapped to the coordinate system of the calibration image using the pointer coordinates and the calibration image.
