ABSTRACT:
A method of estimating the orientation of digital ink is provided. The includes measuring, at a sampling rate during writing by an optically imaging pen on a surface printed with tags, the azimuth of the pen, and estimating, at the computer system, the orientation of the segment of digital ink using the measured azimuth of the pen at the sampled points. Each tag encodes data on an identity of the surface associated with a digital description of the surface and on the respective location of that tag on the surface. The digital description is stored by a computer system networked with the pen and the digital ink is generated by associating the digital description with the data encoded by the tags optically imaged by the pen during the writing.
