The visualization subsystem in virtual simulators is one of the most important components, as it provides the necessary level of trainable immersion in virtual space. The choice of optimal visualization components is a non-trivial task solved on the basis of an expert approach, which allows for the possibility of errors both in the architecture of this subsystem and in the parameters. The paper proposes an algorithm for selecting visualization components for virtual training systems, based on correlation matrices for quantitative and qualitative evaluation of components. The values of the matrices were obtained on the basis of experimental studies and comparison of components on a set of typical simulators, which make it possible to evaluate the components according to the metrics of the quality of display, interaction, movement, and sound. The proposed approach allows to reduce the probability of errors in the synthesis of the visualization subsystem of virtual training systems. [ABSTRACT FROM AUTHOR]

An urgent problem in the development of virtual training complexes is the implementation of an interface for displaying the progress of training, visualization of the collected data, as well as solving problems related to the launch of the simulator and user authorization. When using game engines (Unity, Unreal Engine and others) and virtual reality technologies, this problem is complicated, especially when the instructor, not the trainee, has to interact with the interface. To solve this problem, it is necessary to separate the interface from the visualization subsystem in the form of a separate module (microservice). Within the framework of this study, it is proposed to implement an interface module in the form of a Web service with the possibility of dynamically updating the page and applying an Activity-based approach. The proposed approach has the following advantages: access differentiation at the Activity level, the general logic of all Activities, the presence of a stack of Activities for storing history and changing Activities during the operation of the management system. The paper describes the concept of developing a Web interface based on Activities, as well as an example of its approbation for managing virtual training complexes. [ABSTRACT FROM AUTHOR]

A promising direction in the development of virtual training complexes is their decomposition into separate modules (microserves), which will reduce their connectivity and overall design complexity. The problem of organizing the interaction of several heterogeneous modules within a single microservice architecture using UDP and TCP/IP data transfer protocols is considered. To solve this problem, the concept of organizing inter-module interaction based on a unified system of procedures is proposed, which allows for the coordinated operation of all modules. To implement the exchange of information and the functioning of all components of the simulator, a control protocol based on the JSON standard has been developed. Communication channels and the interaction process, as well as error handling, are managed by a separate server module. The developed system is able to provide platform independence and scalability of each module, as well as the possibility of independent deployment of virtual training complexes. [ABSTRACT FROM AUTHOR]
