MOTION DETECTION SAMPLING FOR WRITING AND TRACKING INSTRUMENTS

摘要

A system for tracking writing motions internally to the pen (2) and communicating such motions to a computer systems. In a preferred embodiment the present invention uses multiple tubes with electrically active material with viscosity surfaces in order to generate the necessary signals to determine the motion of the device in a targeted number of degrees. The data is then filtered (by filter 3100) and optionally processed (by processor 3300) and stored (storage connected to output line 3500). The data (3500) then can be downloaded to a computer to determine the motion of the pen (2).
