Augmented reality is one of the new ways to express, supplement and expand the content of any product, including printed ones – books, magazines, postcards, clothing and more. The technological process of creating products with augmented reality includes many stages, each of which requires control. This is especially true of the process of creating augmented reality elements (markers), which will then be printed, scanning which the user will be able to play and see the content. One of the important operations is testing these elements, because without confidence in the correctness of the reproduction of virtual content, it is impossible to continue the following processes.

These scientific articles are devoted to the study of the relationship between information, energy and material flows of the process of creating elements of augmented reality, as well as determining the qualitative and quantitative parameters of these flows and developing an information model of the testing process (scanning and playback) of augmented reality elements on the screen of the scanning device (smartphone, tablet, etc.).

To solve this problem, the paper first analyses the research in the field of augmented reality to determine the main trends and features in it. Next, a model of the technological process of creating elements of augmented reality is constructed and the qualitative and quantitative parameters of 3 flows are established: information, material and energy. The next step is to develop a scheme of relationships between these flows for the process of creating elements of augmented reality. As this process is complex and multi-stage, this process is decomposed for a more detailed study. Thanks to her, a new object of research is chosen – a smartphone camera, which is responsible for performing the technological operation of testing as one of the most influential and important. Next, i the features and principles of the smartphone camera are analysed and the principle is selected on which the device will be based – the marker technology as the simplest and easiest to create and use, which is explored further. The method on the basis of which augmented reality will be created and which will be the basis for the testing (scanning and recognition) process is determined. Sobel’s method is chosen. Based on the obtained results, an information model of the testing operation is designed and the main parameters of 3 flows are determined – qualitative and quantitative. The last step is to construct a mathematical model of this process, which allows one to understand the relationship between information, energy and material flows.

Keywords: augmented reality, elements of augmented reality, digital content, testing, information flow, energy flow, material flow, decomposition, information models, mathematical models.
