The Digi-Sync pen is a digital pen, which has been designed in such a way that it overcomes the drawbacks of
surface dependence and high cost factor present in the existing digital-pens. The Digi-Sync Pen, an input device that tracks
the motion of the pen and creates a soft copy of handwritten notes and data. The Digi-Sync Pen employs bitmapping
technology and sophisticated piston switching mechanism for motion tracking and recording respectively, thus making it
surface independent and cost effective.
