Extended-Reality Technologies: An Overview of Emerging Applications in Medical Education and Clinical Care.

The purpose of this article is to propose a View Sharing Augmented Reality (AR) interface aimed at improving situation awareness (SA) during military operations. Battlefield Augmented Reality System (BARS), a mobile AR system, supports real-time battlefield situation awareness (SA) for mission execution through collaborative information sharing. Video-based View Sharing AR interface that provides the perspective of team members located remotely can enhance team-level SA. However, instances have been identified where providing the perspective of team members moving in directions different from the user’s path can lead to user confusion and have a negative impact on mission execution. In this study, we investigate the influence on SA when presenting the perspective of team members with different path direction through a View Sharing AR interface and to examine the impact of visual AR cues supporting spatial awareness on SA improvement. The study was designed to experience the View Sharing AR interface in a virtual reality (VR) environment using the Unity3D game engine. The experiments involved performing tasks to suppress enemies with three different path direction variances in perspective provision and receiving support from four visual AR cues. SA was measured through SA Global Assessment Technique (SAGAT) and Performance measurement. The research findings indicate that differences in path direction negatively affected SA, with the lowest SA observed when the path difference was 90°. Furthermore, visual AR cues, when providing Tramline cues, demonstrated the highest SA, showing interaction effects with path direction differences.

The perceptual behavior of consumers on a product displayed in the market has a vital role in analyzing the importance given to that product. Therefore, various strategies have been developed to understand this consumer behavior in the selection of products. Immersive technologies like virtual, augmented, and mixed reality are among them. With the foremost feature of immersion in the virtual world and interaction of users with virtual objects, virtual reality, and augmented reality have unlocked their potential in research and a user-friendly tool for analyzing consumer behavior. In addition to these technologies, mixed reality also has a significant role in investigating consumer behavior. Studies on immersive technologies in food applications are vast, hence this review focuses on the applications of virtual, augmented, and mixed reality in the food selection behavior of consumers. The behavioral studies are elicited to develop new products based on consumer needs, to understand the shopping behavior in supermarkets for real-time usage, and to know the influence of emotions in a selection of products. The findings suggest that virtual, augmented, and mixed reality induce immersion of the users in food selection behavioral studies. Information on the technological advancements in the tools used for bringing immersion and interaction are discussed for its futuristic applications in food. Though immersive technology gives users a realistic virtual environment experience, its application in food systems is in the budding stage. More research on human response studies would contribute to its innovative and inevitable application in the future.

Technologies such as Virtual and Augmented Reality have gained popularity lately. Because of their convenience and accessibility, these technologies have been adopted in various domains. Virtual reality and augmented reality create an immersive experience, enabling 3D visualization of the content. This technology lets you visualize data from different sensors at the same time, overlaying relevant and helpful information over your environment through a headset. In this article, we give a perspective on these technologies from a biomedical engineering standpoint. In this article, we discuss the various technologies of current biomedical engineering. These technologies allow us to move beyond traditional 2D images towards 3D models that can be made visible and manipulated with Augmented and Virtual Reality. The basic applications of biomedical engineering include representation of mechanisms in space and time dimensions and three-dimensional visualizations of difficult structures in anatomy. The article is an attempt to bring the latest results on the benefits of virtual and augmented reality in biomedical engineering.

Computational thinking (CT) skills are increasingly important in education to prepare students for the challenges of the digital age. Augmented Reality (AR) and Virtual Reality (VR) have been introduced as immersive technologies that have the potential to enhance CT skills through more interactive learning experiences. However, there is still a gap in understanding the effectiveness of these technologies in supporting the development of CT, particularly in different levels of education and disciplines. Although several studies have highlighted the benefits of AR and VR in education, no systematic review integrates these findings to identify advantages, challenges, and opportunities for further implementation. Therefore, this study conducted a systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by analyzing 25 empirical studies (AR=17, VR=8) obtained from the Scopus database (2008-2024). The analysis addresses four key research questions: (1) the current state of AR/VR in CT development, (2) their advantages, (3) implementation challenges, and (4) future research directions. The results show that AR is more widespread than VR at various levels of education, with dominance in higher education followed by secondary and primary schools. Computer science is the main field of application of AR and VR, while AR is also widely applied in mathematics to increase interest and problem-solving. A total of 11 studies reported significant impacts of these technologies on CT, with AR being superior in increasing student motivation and engagement, as well as aiding in problem-solving and debugging. In contrast, VR provides a more immersive learning experience by strengthening concept understanding, especially in programming and recursion. However, several obstacles in the application of AR and VR, such as hardware limitations, costs, and user skills, affect the effectiveness of these technologies in the learning environment. This study also identified potential future research, including the exploration of VR in primary and kindergarten education, the application of VR in non-computer science fields, and the efficient use of these technologies in supporting the CT process. This study provides more precise insights into the optimal ways of utilizing AR and VR in developing CT skills. It is a reference for educators, policymakers, and researchers in supporting CT learning.

Introduction. The purpose of the paper is to justify the possibility of developing ontology of augmented reality as a special sphere of social space. A comparative analysis of approaches to the interpretation of reality in philosophy and theoretical sociology is carried out. The original provisions of the conceptual model of social reality and social actuality have been formulated. The concepts of actual and virtual social actions are introduced and analyzed.Methodology and sources. The main provisions of phenomenological sociology are used as the methodological basis of the study: A. Schutz's interpretation of social reality as a fragment of being translated into the world of intersubjective, and P. Berger and T. Luckmann's characterization of the reality of society as a process of its construction in practical activities. The features of augmented reality, revealed in the works of R. Azuma, P. Milgram, A. F. Kishino, H. Papagiannis, A. M. Larsen, S. A. Glazkova, O. N. Kislova and other researchers, are taken into account. Descriptions of the characteristics of augmented reality devices are derived from reports from research center heads: the descriptions of the characteristics of augmented reality devices are derived from reports from the heads of research centers involved in the development and implementation of digital technologies: universities in London, Tokio and Toronto, Hasso-Plattner Institute in Germany, Finnish company Senseg, company Disney Research, company High Fidelity, MIT self-assembly labs, MIT Media Lab Group, San Francisco-based Detour startup, Google and Microsoft etc.Results and discussion. The environment shaped by augmented reality is much more complex than it is in its immediate perception. It includes four spaces: 1) subject world, 2) the mental world and 3) the hybrid world as a symbiosis of real and imaginary worlds, or 4) symbiosis of real-world fragments – torn in space and time and combined with technology in devices that give the individual's ability to be present when observing their combined existence.Conclusion. Augmented reality complicates virtual reality, adding to its content in addition to fictional characteristics the content of practical actions. Augmented reality, using the virtual reality resource, becomes reality as the basis of practice. Augmented reality not only “begets” the world, but is in direct practical contact with it, thus becoming a special side of social reality.

Advanced fire control technologies that utilize computer vision-guided target recognition will enable dismounted soldiers with augmented reality displays, such as the integrated visual augmentation system, enhanced situational awareness. Here we describe a virtual reality framework and environment for the design and evaluation of computer vision algorithms and augmented reality interfaces intended to enhance dismounted soldier situational awareness. For training models, synthetic image datasets of targets in virtual environments can be generated in tandem with neural network learning. To evaluate models under simulated operational environments, a dismounted soldier combat scenario was developed. Trained models are used to process input from a “virtual camera” in-line with a rifle-mounted telescopic sight. Augmented reality overlays are projected over the sight’s optics, modeling the function of current state-of-the-art holographic displays. To assess the impact of these capabilities on situational awareness, performance metrics and physiological monitoring were integrated into the system. To investigate how sensors beyond visible wavelength optical imaging may be leveraged to enhance this capability, particularly in degraded visual environments, the virtual camera framework was extended to introduce methods for simulating multispectral infrared imaging. Thus, this virtual reality framework provides a platform for evaluating multispectral computer vision algorithms under simulated operational conditions, as well as iteratively refining the design of augmented reality displays. Improving the design of these components in virtual reality provides a rapid and cost-effective method for refining specifications and capabilities toward a field-deployable system.

Augmented Reality is considered one of the most promising technologies for Industry 4.0. Augmented Reality allows to display the needed information at the right time and to locate it in the desired space, superimposing it to the real world. In this way, it could simplify the work of industrial operators in a variety of tasks, from planning and commissioning to assembly and maintenance. Despite the growing research interest and efforts for the development of Augmented Reality applications and technologies for the industrial domain, Augmented Reality is still rarely used in real industrial procedures, often remaining at a conceptual level. In fact, developers fail to completely answer the actual needs of industries and workers because of a lack of knowledge of the context and the absence of guidelines to drive the design and development of Augmented Reality applications. One of the open issues is the choice of the proper visualization methods to display technical information in Augmented Reality, which is not trivial. Both the paper-based documentation, based on text and illustrations, and digital documentation, including CAD models and image or video-based tutorials, present different criticalities when adapted to the Augmented Reality technology. Other visual material has been developed specifically to be used in Augmented Reality, but it is difficult to use because of a lack of standards which are instead present for the former paper-based and digital documentation. In this work, we categorize and compare different Augmented Reality visual assets, illustrating their advantages and disadvantages and providing directions for future research.

Technologies such as (AR) Augmented Reality &(VR) Virtual Reality, which provide immersive digital experiences, interactive environments, simulation, and engagement, have completely changed how we approach learning. However, in order to meet the huge demand in education, these technologies which are still in the emerging stage need to be heavily customized and heavily invested in. This thorough analysis seeks to contextualize the last few years of development of Virtual and Augmented Reality in the Education. For additional study, a total one thousand five hundred and thirty-six articles are chosen using text mining and theme analysis techniques. Based on earlier research on AR and VR in education, hypotheses were developed and are currently being processed and analysed to reveal the current development in literature via Augmented Reality and Virtual Reality, applications, benefits, and future directions. The findings show that wearable technology has contributed significantly to the exponential expansion in the use of Virtual and Augmented Reality in education in recent years. Results also highlight the need for faster adoption and customization of these technologies in educational institutions, based on secondary data. An increasing number of educational applications for the learning process are emerging as Virtual and Augmented Realityexp and quickly. It is advised that researchers stay up to date on the gaps in AR and VR’s Changeover to education &develop practical adaptation strategies to maximize the benefits of these technological development with significant developments in high-speed transmission and processing, AR &VR are developing as Display Platforms for Next Generation for more intimate human-digital interactions. Nonetheless, matching the extraordinary Human Vision Performance while keeping Near the Eye Display module tiny and lightweight presents unprecedented hurdles for optical engineering. Fortunately, new advances in Holographic Optical Elements HOEs and Lithography Enable Devices present novel approaches to overcoming these challenges in Virtual and Augmented Reality which would otherwise be problematic with traditional optics

The visualization of medical images with advanced techniques, such as augmented reality and virtual reality, represent a breakthrough for medical professionals. In contrast to more traditional visualization tools lacking 3D capabilities, these systems use the three available dimensions. To visualize medical images in 3D, the anatomical areas of interest must be segmented. Currently, manual segmentation, which is the most commonly used technique, and semi-automatic approaches can be time consuming because a doctor is required, making segmentation for each individual case unfeasible. Using new technologies, such as computer vision and artificial intelligence for segmentation algorithms and augmented and virtual reality for visualization techniques implementation, we designed a complete platform to solve this problem and allow medical professionals to work more frequently with anatomical 3D models obtained from medical imaging. As a result, the Nextmed project, due to the different implemented software applications, permits the importation of digital imaging and communication on medicine (dicom) images on a secure cloud platform and the automatic segmentation of certain anatomical structures with new algorithms that improve upon the current research results. A 3D mesh of the segmented structure is then automatically generated that can be printed in 3D or visualized using both augmented and virtual reality, with the designed software systems. The Nextmed project is unique, as it covers the whole process from uploading dicom images to automatic segmentation, 3D reconstruction, 3D visualization, and manipulation using augmented and virtual reality. There are many researches about application of augmented and virtual reality for medical image 3D visualization; however, they are not automated platforms. Although some other anatomical structures can be studied, we focused on one case: a lung study. Analyzing the application of the platform to more than 1000 dicom images and studying the results with medical specialists, we concluded that the installation of this system in hospitals would provide a considerable improvement as a tool for medical image visualization.

Augmented and virtual reality have the potential to improve various aspects of everyday life such as tourism. An elementary part of tourism is the organization and execution of guided city tours. In case of tours for virtual cities, such as in the case of no longer existing ancient settlements, a combination of augmented and virtual reality may render high benefit for collaboration between guide and visitors. Immersive technology has been shown suitable for collaborative systems by previous research, as they can provide a better experience than other technologies. However, recent literature analyses showed that there is a lack of research regarding the role of augmented reality supporting the active/leading user role in such scenarios. Usually, augmented reality is used for the users who are passively experiencing the virtual environment and not for the one controlling it. However, we think that augmented reality has a large potential to improve the workflow of such a primary user. To investigate this research question, we present a collaborative system in this work, which implements a virtual city tour. In this system, the guide is using augmented reality and the visitor is immersed in the virtual city using virtual reality glasses. To implement a valid research prototype, the system has been developed in close feedback with experts in the field of guided city tours.
