ABSTRACT:
A digitizing stylus for use with a tablet for measuring the angle between a gravity vector and the longitudinal axis of the barrel of the stylus for calculating pitch angle and barrel rotation of the stylus includes a housing having an electrolytic solution. A plurality of electrodes are disposed within the housing and extend into the electrolytic solution. The electrodes generate an output signal based upon the distance the electrodes extend into the electrolytic solution. A sensor is interconnected to the plurality of electrodes for sensing changes in the output signals for computing pitch angle and rotation of the stylus.
