Abstract
A system and method is described for providing an encoding scheme for a bit stream and displaying or printing the encoded bit stream. Using the encoded bit stream, a pen with a camera may capture an image of a portion of the encoded bit stream. The captured image may then be decoded to provide an indication of the location of the image in relation to the encoded bit stream. The encoding scheme includes information regarding orientation, thus making decoding easier.

3. A method for decoding an encoded image comprising the steps of:
-
receiving said encoded image;
determining a rotation of said encoded image to be aligned with a predefined grid orientation;
retrieving a pattern from said encoded image based on said determination of rotation step;
determining an orientation of said pattern;
rotating said pattern based on said determining an orientation step; and
,decoding the rotated pattern to extract a data stream. - View Dependent Claims (4, 5, 6)
