Section 1: Background and Basics
The Wacom 6D Art Pen
was introduced by Wacom along with its Intuos 3 line of pen tablets
and its newest line of Cintiq pen-abled touch displays. The pen itself added a valuable function to the already generous offering of features of Wacom’s tablets and pens, active ROTATION. The pen’s sensors are able to detect the angle in which the pen is rotated. My best guess is that this is accomplished through tracking of two sensor points located near the pen’s tip; the two locations are mapped and the angle between the two in relation to the tablet sensor’s orientation measures the pen’s orientation in regard to rotation. The pen’s location on the tablet, and thus on-screen, is based on the center of these two points.
