Abstract:
A method for calibrating a digital stylus comprising imaging a portion of a calibration pattern area of a data encoding pattern using an imaging module of the stylus in order to generate calibration data representing an error in alignment for the stylus, and using the calibration data to adjust subsequent measurements from the stylus in order to compensate for the error.
