Decoding digital information included in a hand-formed expression

A device comprising:

• an imaging circuit operable to acquire digital information encoded in a hand-formed expression formed on a surface by a handheld writing device, the digital information encoded in the hand-formed expression including at least binary data linearly deposited along at least part of the hand-formed expression;
• a translator circuit operable to decode the digital information corresponding to an environment of the handheld writing device when the expression was formed on the surface;
• and
• a correlation circuit operable to generate a signal indicative of the environment of the handheld writing device when the expression was formed on the surface.

A method comprising:

• acquiring information encoded in a track formed on a surface by a manual writing device, the information encoded in the track form including at least binary data linearly deposited along at least part of the track formed;
• interpreting the-information encoded;
• and
• generating a signal indicative of the context of the manual writing device when the substance was deposited.

A device comprising:

• means for acquiring information encoded in a track formed on a surface by a manual writing device, the information encoded in the track formed including at least binary data linearly deposited along at least part of the track formed;
• means for interpreting the information encoded;
• and
• means for generating a signal indicative of the context of the manual writing device when the substance was deposited.
