The key goal of modern biological and ecological education is the process of forming a natural scientific worldview based on the biological picture of the world and, in particular, the formation of biological (ecological) thinking based on a systematic approach. This contributes to the formation of a personality capable of independently building a trajectory of personal development, subject to mastering key competencies. An innovative approach to the formation of a biological picture of the world, from the authors’ point of view, is the use of immersive technologies in the educational process in biology and ecology. The article discusses the implementation of new teaching aids and technologies, especially virtual and augmented reality, 3D images in the biological and ecological education of school students, and the problems of a comprehensive study of the influence of VR and AR technologies on students in the context of project activities. It proposes several approaches to the training of teachers and instructors who can effectively organize an immersive educational process, build flexible scenarios for the inclusion of these technologies in project activities. The examples of students’ project work on the basics of genetics in virtual laboratories using virtual and augmented reality technologies are examined. In particular, an innovative approach to teaching the foundations of heredity is revealed in accordance with the challenges of our time, taking into account social demand, allowing to provide a personality-oriented approach to learning, variability of the process, increase the effectiveness of the material being studied, and adapt participants to the conditions of passing the mandatory standard. At the diagnostic stage of the study, it was revealed that the heredity basics module in the school biology course is a complex topic. This served as the basis for starting the development of the author’s methodological construct, which is based on cultural, historical and problem approaches. When designing a construct, the material on the basics of heredity is divided into semantic modules – didactic units, the structure of which assumes the presence of a motivating task, a problem situation and work in a virtual training ground. The approbation of the innovative module for the study of the molecular foundations of genetics by school students shows that for its implementation into the practice of general and additional education, it is necessary to update the material base, to conduct both real and virtual genetic experiments, as well as to improve the qualifications of teaching staff.

The article deals with the approach to developing an advertising multimedia product for the promotion or sale of goods or services. Under the advertising product is an advertising video, an interactive commercial, 3-D advertising, virtual and augmented reality, an online store. Based on the analogy method, a diagram of the process of perceiving the advertising multimedia product by the user is presented. The use of the hybrid approach of customer development for updating the multimedia product and taking into account the virtual values of users is substantiated. Developed scenarios for the development of a multimedia product, depending on the results of achieving the planned goals. The sequence of multimedia product development is proposed based on the convergence of face-to-face and screen-to-screen approaches.

Forest firefighting missions encompass multiple tasks related to prevention, surveillance, and extinguishing. This work presents a complete survey of firefighters on the current problems in their work and the potential technological solutions. Additionally, it reviews the efforts performed by the academy and industry to apply different types of robots in the context of firefighting missions. Finally, all this information is used to propose a concept of operation for the comprehensive application of drone swarms in firefighting. The proposed system is a fleet of quadcopters that individually are only able to visit waypoints and use payloads, but collectively can perform tasks of surveillance, mapping, monitoring, etc. Three operator roles are defined, each one with different access to information and functions in the mission: mission commander, team leaders, and team members. These operators take advantage of virtual and augmented reality interfaces to intuitively get the information of the scenario and, in the case of the mission commander, control the drone swarm.

Background: The application of virtual and augmented reality technologies to orthopaedic surgery training and practice aims to increase the safety and accuracy of procedures and reducing complications and costs. The purpose of this systematic review is to summarise the present literature on this topic while providing a detailed analysis of current flaws and benefits. Methods: A comprehensive search on the PubMed, Cochrane, CINAHL, and Embase database was conducted from inception to February 2021. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used to improve the reporting of the review. The Cochrane Risk of Bias Tool and the Methodological Index for Non-Randomized Studies (MINORS) was used to assess the quality and potential bias of the included randomized and non-randomized control trials, respectively. Results: Virtual reality has been proven revolutionary for both resident training and preoperative planning. Thanks to augmented reality, orthopaedic surgeons could carry out procedures faster and more accurately, improving overall safety. Artificial intelligence (AI) is a promising technology with limitless potential, but, nowadays, its use in orthopaedic surgery is limited to preoperative diagnosis. Conclusions: Extended reality technologies have the potential to reform orthopaedic training and practice, providing an opportunity for unidirectional growth towards a patient-centred approach.
