TouchPanel Check
For each of the nine reference points on the screen, the distance between the detected pressed
position and the nearest reference point is displayed. The distance is displayed continually near
each reference point.
If all the distances between each detected pressed position and the nearest of the five
reference points on the screen (at the four corners and the center) are within ±12px, the [OK]
button appears. (However, even when the [OK] button is being displayed, if you press the
screen again and the distance exceeds ±12px, the [OK] button disappears.)
