In marker-based augmented reality (AR) systems, markers are usually relatively independent and predefined by the system creator in advance. Users can only use these predefined markers to complete the construction of certain specified content. Such systems usually lack flexibility and cannot allow users to create content freely. In this paper, we propose a virtual marker technique to build a marker-based AR system framework, where multiple AR markers including virtual and physical markers work together. Information from multiple markers can be merged, and virtual markers are used to provide user-defined information. We conducted a pilot study to understand the multi-marker cooperation framework based on virtual markers. The pilot study shows that the virtual marker technique will not significantly increase the user’s time and operational burdens, while actively improving the user’s cognitive experience.

Object Of Study

The paper describes the concept of augmented reality. Based on literature analysis, the authors claim that augmented reality technology enriches human experiences with digital data. The introduction of augmented reality applications and services provides an opportunity to increase the realism of research, while also offering an enhanced emotional and cognitive experience. Therefore, it can be an effective tool for the organization of learning in schools, colleges and universities.Augmented reality technologies can be interesting as an object of study as well. To do this, scientists need to design, develop and test appropriate methodologies.This paper explores one of the components of such techniques. The authors analysed several platforms for creating augmented reality applications. Unity, Vuforia and 3d-Studio were chosen for the purpose of analysis. Using them, the authors developed a fragment of the content of education. It contains instructionsfor creating an augmented reality application. The paper contains the author’s account of the process of training future teachers of computer science at Ternopil Volodymyr Hnatiuk National Pedagogical University (Ukraine). Based on the conducted study, the authors claim that students showed considerable interest in augmented reality technologies and the content of their training.
