Certain user input devices such as touchscreens needs to be calibrated. For this, the GINPUT module provides a calibration dialog. The calibration uses a tree-point algorithm. Three calibration points (cross hairs) will show up, one after another. Each of the crosses needs to be pressed as precisely as possible. At the end a fourth calibration cross will appear in the center of the screen. This last calibration point is used to test whether the calibration was successful. If the difference between the internal read-out of the touch coordinate and the expected result is too big the process will be restarted automatically. See Tolerance for more information.
