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

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.

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.

A total of 13 studies were selected for analysis and the results determined that most of the studies were conducted within the last three years. The largest number of studies included participants with intellectual disabilities and AR or VR based instruction was mainly taught by their school teachers over 11-20 sessions. In 7 out of 13 studies, AR or VR was used alone while in 6 studies, it was used combined with other practices. Dependent variables of the studies included academic learning achievement(reading, science, geography) and attitude(motivation, interests, attention, learning flow). The results of the studies determined AR- or VR-based instruction was generally effective for enhancing both academic learning achievement and attitude of students with disabilities. The educational content type used in AR instruction most frequently across the studies was the observation operation type and it was more effective when AR was used combined with explicit instruction. Also, both studies on VR-based instruction primarily used the immersive type and it was also effective for enhancing students’ learning achievement and attitude. Based on the results, the study provides suggestions on direction of future research.

Educational technology can enhance learning by supporting the learning environment through various digital resources. There have been numerous emerging technologies which are able to bridge the resource gap in learning environments enabling students to get access to an abundance of resources on digital platforms. This paper presents a literature review, exploring the potential of using Mobile Augmented Reality (AR) and Virtual Reality (VR) technologies to support experiential learning in South African institutions. While there have been studies which aim to assess the use of AR and VR for educational purposes such as in mining safety education in South Africa, there is a need for studies that look at the potential of AR and VR in augmenting higher educational institutions such as universities and Technical and Vocational Education and Training (TVET) colleges which require students to complete an experiential learning component in their studies in order to complete their qualifications. The study aims to establish the potential role that AR and VR can provide in enhancing experiential learning by providing students with practical experience in various educational fields, leveraging augmented and virtual reality technologies to simulate such learning environments.

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.

Rendering haptic feedback on the wrist is an effective solution for freeing users' hands during virtual interactions while still providing haptic feedback, mostly focusing on Virtual Reality (VR) environments. Unfortunately, whether these solutions can be extended to Augmented Reality (AR) interactions has not been investigated before. In this paper, we investigate the perceptual differences between VR and AR environments with a user study experiment based on a stiffness discrimination task. Our findings revealed similar task accuracy and sensitivity in VR and AR but different exploration behaviors (i.e. higher interaction time in AR) and user experience (i.e. higher enjoyment and less mental fatigue in AR). These differences may be explained by the increased cognitive load and the environmental immersion in AR, where users navigate both virtual and real elements simultaneously. This suggests that visuo-haptic psychophysical findings obtained in VR can be extended to AR, even though user experience and exploration behavior might differ.
