Article with visual code, visual code generating apparatus and information conveying method

摘要

An article having a visual code that can visually and directly convey a message to a human and accurately and indirectly convey information through an apparatus with an optical reading function. Visual code 1 is attached to an article. In visual code 1, symbol arrangement pattern 13, which indicates a message that can be visually recognized by a human, is formed by forming code space 11 by arranged multiple regions 12 in a grid, selecting one or more than one region 12 from among multiple regions 12 in code space 11, and placing pattern element 15 in each of selected regions 12. Each region 12 where pattern element 15 is placed so as to form symbol arrangement pattern 13 among multiple regions 12 in code space 11 indicates ON; each region 12 where pattern element 15 is not placed indicates OFF.

1. An article characterized in that the article has a visual code wherein a symbol arrangement pattern, which comprises a single symbol pattern or a plurality of symbol patterns that indicate a message that can be visually recognized by a human, is formed by selecting one or more than one region from among a plurality of regions arranged like a grid in a two-dimensional space, and placing a pattern element with a predetermined shape in each of the selected regions; each of the regions where the pattern element is placed so as to form the symbol arrangement pattern among the plurality of regions in the two-dimensional space indicates ON; each of the regions where the pattern element is not placed so as to form the symbol arrangement pattern among the plurality of regions in the two-dimensional space indicates OFF; and linked information that is different from the message is linked to binary information that is specified by the regions indicating ON and the regions indicating OFF, corresponds to the symbol arrangement pattern, and can be recognized by an apparatus with an optical reading function, and
wherein a guide pattern, which enables a reading apparatus to correct a misalignment between the reading apparatus and the visual code, or enables the reading apparatus to recognize a reading direction of the visual code, when the reading apparatus reads the visual code, is placed in the two-dimensional space where the visual code is formed.
