5. How to Hold the Pen Properly

Place the lamp in such a way that the pen shadow, as seen by the webcam, has an approximately horizontal inclination.



You should hold you pen inclined, with the hand comfortably leaning on the paper, and your fingers not too close to the pen tip. Avoid that you fingers' shadow appear inside the white rectangle where the pen shadow is searched, in order to avoid interference. Do not hold you pen upright, too distant from the tip or occluding too much the blue cap.
