In terms of information overload, the issue of solidity accommodation of knowledge turns to be an essential one. The technology of mnemonic coding (semantic semiotic interpretation) of educational texts is the model rendering the natural basis of perception, storage and reproduction of information. The main concept of the technology is presented in the following way: any educational text is transformed by simulating coding of the units (signal riddles, logical chains) with the help of specific signs (signals, symbols) and within the framework of a certain algorithm. From the point of view of visual arts, the signal riddles present restricted by a small square area where special signs serve as signals for reproducing a text. They serve as graphic images of a piece of a text in the role of “visual statements”. The level of success in drawing up and solving signal riddles is determined by certain rules’ compliance.
