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.
