Abstract
Disclosed is a method and a device for obtaining precision data acquisition via hand writing/drawing without requiring the use of a transducer pad, the screen of a monitor, or a scanner. As such, writing/drawing can be applied to almost all kinds of material surfaces, including books, fabrics, labels, etc., with or without showing an ink mark. Graphic and text images can all be effectively processed. Data acquisition function is accomplished by continuously monitoring the orientation of a magnet ball installed at the tip of a magnetomechanical ball-pen device whose outlook resembles a regular pen. When powered by a battery with self data-storage capability, the disclosed method and device allow for a new class of instrumentations that data acquisition function is carried out at the same time whenever hand writing/drawing is applied in the normal manner.
