Tagology is an experimen to create a language for both humans and computers.Tagology codes represent two meanings: a logo to be read by people and a binary code for computers.

Some existing pictograms and ideograms can be used, while many new ones can be created. Digital readers, such as the camera on the mobile phone, can be used to read, translate and learn unfamiliar logos. Examples of usage are: direction signs, product information, passwords, art and games. But above all, it’s an experiment to learn about how people and machine use language.

Optical readers, such as a webcam, or the camera on your mobile phone can read these images as binary code. The first square is a binary 1 (1), the second 10 (2) the third 100 (4), etc. The unique number refers to information in a database: 100100011 means X. Here, the rectangle serves as a marker to identify the position and size of the code and its bits. Other markers can be used too. Practice shows communication even works when lines are fuzzy or the reading surface is tilted.

With a 5x6 matrix, logos can be created which are still readable and writable for humans, while it provides over a billion unique codes for the databases running in the back. In most languages people need only about several thousand words, while many nouns, verbs and adjectives are used in most languages. Next, grammatical logos (e.g. plural, tense) and phonetic logos for names need to be generated. This adds up to about 10.000 logos. Within a matrix of one billion possibilities, there is enough room to create recognisable shapes.
