The concept and technology of augmented reality, tracking technologies are considered. The substantiation of the relevance and timeliness of its use to support educational processes is given. The article explores the use of augmented reality technologies in teaching students' spatial thinking, which saves time on the transfer and assimilation of information received by students within the framework of this discipline. The analysis of existing research in the field of application of augmented reality technology in teaching the discipline \"Descriptive geometry\" is carried out. The possibility of using augmented reality technology in education for the purpose of visual presentation of educational material is shown. A project for the development of a mobile AR application for visualizing the tasks of a textbook on descriptive geometry based on the Vuforia platform is considered. The proposed software product is implemented on a mobile platform with the Android operating system. When developing software, the C # programming language is used to write scripts to implement the required functionality, in particular, interactive interaction with three-dimensional objects.","PeriodicalId":135912,"journal":{"name":"Proceedings of the 31th International Conference on Computer Graphics and Vision.

The paper considers the features of registering human movements based on various methods, describes the problems in assessing gait parameters based on accelerometric data of a mobile phone. The study involved 32 people aged 15 to 67 years, male and female, with different physiological characteristics (height, weight, posture). Also, two twins with the same physiological parameters and a person who underwent surgery on the knee joint were involved in the experimental group. The form of clothing was different-from tight-fitting trousers to loose trousers, and sneakers, shoes and shoes (for women) with low heels were used as shoes. The research methodology included the main types of movements that are performed in a person's daily life when walking. During the research, informative parameters were analyzed: the average value, the mean square deviation, the signal forms (the value of the correlation coefficient). In the course of the research, it was found that the use of a single accelerometric sensor of a mobile phone allows you to distinguish between the movements of a person when moving in different conditions (form of clothing, type of road, etc.), as well as to distinguish people by the features of movements.","PeriodicalId":135912,"journal":{"name":"Proceedings of the 31th International Conference on Computer Graphics and Vision.
