Artificial Intelligence and Virtual Reality in Headache Disorder Diagnosis, Classification, and Management.

Anatomy education (AE) is poised for a substantial revolution, propelled by advancements in artificial intelligence (AI) and virtual reality (VR) technologies. These novel tools are set to transform the teaching and learning of anatomy, providing tailored, interactive, and immersive experiences that may improve student engagement, retention, and overall educational outcomes. The combination of AI and VR technologies in anatomy teaching can furnish students with a more thorough comprehension of the human body, facilitating a profound appreciation for the intricacies of anatomy. Furthermore, AI and VR technologies can enhance the cultivation of critical thinking and problem-solving abilities, which are vital for success in the medical field. AI and VR technologies can facilitate the connection between theoretical knowledge and practical application by offering students engaging and immersive learning experiences. Moreover, these technologies facilitate students' exploration of the human body in a highly detailed and realistic way, enabling them to visualize and engage with intricate anatomical processes. We hypothecate that the future of AE hinges on the integration of AI and VR as learning tools.

Introduction: the widespread use of cross-cutting digital technologies, as well as the recognition of their importance by the state, led in 2024 to the inclusion of the federal project Artificial Intelligence in the National Project for the Formation of the Data Economy for the period until 2030. Earlier, Russian legislation established the concept of cross-cutting technologies as cross-sectoral technological areas that ensure the creation of innovative products and services and have a significant impact on the development of the economy, radically changing existing markets and/or contributing to the formation of new markets. Among the most popular for application in various sectors of the economy today are such cross-cutting technologies as generative artificial intelligence, the Internet of Things (IoT), augmented and virtual reality. For example, artificial intelligence is increasingly being used to create content, control devices, and virtualize reality. In the context of existing practice, a discussion is developing on the need to balance the interests of the owners of artificial intelligence systems and other such technologies, the users of these systems, and third parties in the process of such interpretation and creation of multimodal data at the output. Purpose: basing on the analysis of Russian and foreign scientific concepts and using the example of generative artifi-cial intelligence, IoT, augmented and virtual reality, to form an idea of the directions of legal regulation of the appli-cation of advanced cross-sectoral technologies from the point of view of law. Methods: empirical methods of com-parison, description, interpretation; theoretical methods of formal and dialectical logic; special scientific methods: legal-dogmatic method and the method of interpretation of legal norms. Results: studying the problems that have arisen or may arise in law in connection with the use of cross-cutting technologies of cross-sectoral purposes (gener-ative artificial intelligence, IoT, virtual and augmented reality), the authors provide a general vision of the state and prospects of legal regulation of the relevant relations. The article considers possible legal approaches to granting protection to objects created with the help of artificial intelligence: copyright protection of a derivative work, legal protection of creative and non-creative photographic works, of original topologies of integrated circuits, of related rights for objects created with the help of artificial intelligence, legal regime of a non-creative database, phonogram, public domain, as well as sui generis legal regime within the framework of the institute of related rights for non-creative objects produced with the help of artificial intelligence. As the generation of content is often closely related to the work with data obtained and processed by means of the IoT technology, the authors put forward ideas regard-ing the harmonization of legislation in these areas. In addition, the use of augmented and virtual reality technologies also involves the creation of content in a certain sense. Conclusions: there is a need for the development of legal regulation addressing the issues of security, protection of personal data and other confidential information. It seems that there is being formed a special sphere of legal regulation related to the exercise of various types of human rights in information and telecommunication networks, when using the IoT as well as virtual and augmented reality tech-nologies. The approach that appears to be promising is defining the legal regime of objects created with the help of artificial intelligence as sui generis or, in the context of the Russian legal system, as rights related to non-creative objects. A positive consequence of the adoption of the regime of related rights for objects created with the help of AI technologies may be seen in that that such recognition will make it possible to protect objects that are currently not covered by any protection regime, which leads to abuse by various claimants to ownership of the rights.

Primary school students often find it difficult to differentiate two dimensional and three-dimensional geometric shapes. Taking advantage of the ability of Virtual Reality (VR) and Augmented Reality (AR) to visualize 3D objects, we evaluate the potential of VR and AR technologies for teaching the lesson of geometric solids to primary school children. To the best of our knowledge there are no previous cases in the literature describing a comparative evaluation of VR and AR technologies in education, and more specifically in the field of mathematics for primary school children. An experimental evaluation was staged to test the following hypothesis: Hypothesis 1: VR and AR applications make the teaching of mathematics more interactive and interesting and they also contribute to a more efficient learning and understanding of mathematical concepts. Hypothesis 2: The use of VR applications is more effective when compared to AR applications for mathematics teaching activities. For the needs of the experimental evaluation, we designed a lesson plan comprised of three activities: Classification of shapes into solid or plane shapes, identification of solid shapes appearing in a typical city environment, and classification of solid shapes. The lesson plan was implemented based on the traditional method that utilizes printed material, three related VR and three AR applications. The developed VR and AR applications for the current research do not require specialized equipment. For the AR applications, the users only need to use their mobile device or tablet and for VR applications they only need to use a mobile phone and low-cost virtual reality glasses. As part of the study 30 fourth, fifth and sixth class primary school students were divided equally into the control group who used the traditional teaching method, and the AR and VR groups who used AR and VR applications respectively. Participants were provided with questionnaires before (pre-test) and after the test (post-test) to measure factors such as user attention, presence, enjoyment, science knowledge, auditory knowledge, and visual knowledge. According to the results, new technologies in education in the form of virtual and augmented reality improve interactivity and student interest in mathematics education, contributing to more efficient learning and understanding of mathematical concepts when compared to traditional teaching methods. No significant difference was observed between virtual and augmented reality technologies with regards to the efficiency of the methods that contribute to the learning of mathematics, suggesting that both virtual and augmented reality display similar potential for educational activities in Mathematics. Based on statistical evidence Hypothesis 1 was accepted and Hypothesis 2 was rejected. The current research is one of the first attempts ever to compare VR and AR technologies for Mathematics teaching activities in primary school. The findings of our research can provide valuable feedback to educators and developers who plan to use or develop VR or AR technologies for educational activities. Given that these days VR and AR applications, like the ones used in the experimental evaluation, do not require highly specialized equipment, the introduction of AR and VR based activities both for in-class and extra curriculum activities provide a promising way for more efficient Mathematics training activities.

With the upsurge of urban construction, public buildings such as museums have attracted more and more attention as the business card of the city. The museum business is developing rapidly, and the artistic concepts appearing in museums are gradually differentiated and conceptualized, paying more attention to the experience and feeling of the visitors. With the continuous intervention of high technology and new media, the visual expression of museums has become more diverse. With the advent of virtual reality (VR) technology, more and more technological means have been introduced into the design of museum exhibits. It eliminates the boring feeling of the general public about the original exhibition method of the museum, while enriching the fun of visiting the museum. To provide visitors with an immersive experience in which virtual and reality intersect, we study the design of a digital immersive interactive experience for museum cultural heritage based on VR technology. By combining current technological development and policy advantages, we describe the innovative ideas and design schemes of museums applying VR and augmented reality technology and discuss the practical value and importance of establishing designs through experiments. The experimental data show that the use of VR technology to digitally design the cultural heritage of museums enhances the immersion and interaction of tourists in the experience, and the score for the VR model was 9.23% higher than that of the traditional forms, which shows that VR promotes the dissemination of the cultural heritage of museums.
