VR refers to a sophisticated technology that generates artificial environments, offering users an immersive experience that simulates presence within a digitally constructed, three-dimensional world. Using devices such as VR headsets, students are able to engage with these virtual environments in a manner that replicates real-world interactions, thereby providing access to experiences that would otherwise be difficult or impossible to attain in reality. This study seeks to investigate the utilization and acceptance of Virtual Reality (VR) technology among teachers and students in schools across the state of Perlis. In the context of a rapidly advancing digital era, VR offers unprecedented opportunities for education by facilitating interactive, immersive learning experiences. However, the extent of readiness and acceptance of this innovative technology among teachers and students in Perlis remains uncertain. Employing a quantitative research methodology, this study gathered data through the administration of structured questionnaires. The results indicate that both students and teachers exhibit a strong interest in integrating VR technology into the educational landscape. The respondents demonstrate a foundational understanding of VR and express confidence that its application in schools can significantly enhance learning outcomes. Despite the widespread enthusiasm for incorporating VR into teaching and learning processes, several critical challenges must be addressed to facilitate its adoption. These challenges include inadequate access to necessary equipment, insufficient training, and a lack of robust infrastructure support. This study offers a set of strategic recommendations aimed at overcoming these obstacles and fostering the broader acceptance and implementation of VR technology in the schools of Perlis.

These findings highlight the potential of MSMPC in enhancing visual communication experiences based on VR technology, paving the way for innovative and immersive storytelling in various domains.

The Reality of Virtual Reality in Echocardiography Education?

Background The aim of this study was to investigate whether the presence of a teacher affects learning related outcomes in teaching basic surgical tasks with a Virtual Reality (VR) headset. Methods 26 fourth-year medical studentsparticipated in a voluntary exercise. Students practiced basic surgical procedure exercises using the VR4HEALTHCARE application in VR with OCULUS Rift S glasses. 12 students performed the exercises under the guidance of a teacher and 14 without the teacher present. After the exercise, the groups filled out a feedback form. Statistical analysis was performed using IBM SPSS Statistics 25.0 software using the Mann-Whitney U test and multivariate analysis of variance. Results The most important data collected related to whether the student learned something new and whether VR adds value to medical education. Ratings were based on a scale of 0–10 (0 = worst, 10 = best). When the teacher was present, on average, the students felt that they were learning something new and gave an average rating of 7.8 ± 1.8, and when the teacher was not present 5.3 ± 2.6 (p = 0.003). VR added value to teaching with a rating of 7.8 ± 1.7 when the teacher was present and 5.5 ± 3.0 when not present (p = 0.045). This study also analyzed specific use of VR for abscess incision, suturing and insertion of a suprapubic catheter. Discussion When a teacher was present VR added value to teaching and the usefulness and usability of VR was experienced more positively. The student should also have adequate knowledge of the subject to be taught before VR training. Conclusions VR adds value to teaching, but VR exercises may not completely replace high-quality traditional teaching methods. Consequently, it is important to determine the differences between VR and traditional teaching methods and how to combine these methods in the future.

A 13-year-old boy presented with an 8-year history of recurrent facial dermatitis. He had a history of atopic eczema and had developed intermittent swelling, redness and scaling of the face for several years, initially thought to be related to sunscreen exposure but more recently associated with prolonged time wearing his virtual reality (VR) headset. The distribution of the rash over the cheeks coincided with areas in contact with the headset rubber foam padding. Patch testing to the British Society for Cutaneous Allergy standard series, facial series, photoallergen series and a sample from the headset foam showed positive reactions to carba mix 3% (day 2+, day 4++), methylchloroisothiazolinone with methylisothiazolinone (MCI/MI) 0.02% (day 2+, day 4+), methylisothiazolinone (MI) 0.2% (day 2+, day 4+), 2-bromo-2-nitropropane 0.5% (day 2+, day 4+), methyldibromoglutaronitrile 0.3% (day 2−, day 4+), benzisothiazolinone 0.1% (day 2+, day 4+), propolis (day 2−, day 4+) and the patient’s own VR headset sample as is (day 2+, day 4+). Carba mix was felt to be relevant to the sponge rubber headset padding, which was also positive on testing. 2-Bromo-2-nitropropane was of current relevance to use of a facial ‘cooling spray’ containing this preservative. The other reactions were of unknown relevance. Avoidance of the headset led to complete resolution of symptoms. The VR company has since provided a cover for the padding, which has allowed our patient to wear the device without flaring his skin. The UK has one of Europe’s largest gaming markets, with projections indicating a surge in video game users from 51.2 million in 2023 to an estimated 57.6 million by 2027. Approximately 56% of the UK population engages in gaming, with most notably the demographic aged 16–24 years reporting 88% engagement in video games, and 68% of individuals aged 7–18 years owning gaming consoles. VR headsets are currently utilized by only 1% of children aged 3–15 years, hindered by the substantial price tag of £1420 for some VR headsets. However, the availability of more affordable alternatives will drive increased usage. Virtual meetings and working from home are becoming commonplace, widening potential exposure to VR headsets in the workplace. Gaming controllers are reported to cause ACD, as well as ‘PlayStation thumb’, with desquamation, lichenified hyperkeratotic papules and fissures on the lateral aspect of the thumbs. PlayStation palmar hidradenitis manifests with discrete, erythematous, tender nodules over the finger pulps and the palmar aspects of both hands, caused by repeated trauma while gaming. To our knowledge, ACD caused by a VR headset has not been previously reported. We would like to highlight this potential new source of ACD to the gaming and wider working population.

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

The article considers the possibility of using virtual and mixed reality in studying the geometry of the crystal lattice in the framework of the course of solid state physics. The application of mixed and virtual reality technologies in the study of various branches of physics is receiving more and more attention. Virtual reality headsets were used in practical and laboratory classes, where students had to create crystal structures and carry out modeling of various processes. When studying complex spatial objects of crystallography, virtual reality technology allowed students to familiarize themselves with the object of study in more detail, understand the structure of crystals and, accordingly, complete the task in a timely manner. At the same time, the prolonged use of virtual reality headsets led to rapid fatigue of students.

Virtual Reality (VR) can support engaging and effective learning and current VR devices commercially available are opening up opportunities and expectations in higher education. An open research question is determining whether the fidelity of the VR device (e.g. resolution, framerate, etc.) impacts learning. This work aims to address this question by conducting a study wherein the quality of the experience and the knowledge acquired using a high fidelity (and high priced) VR headset is compared against a lower fidelity (and lower priced) VR headset. The results of the study do not reveal significant difference in spatial and experiential learning. The user satisfaction and experience are also similar regardless of the headset used.

Growing research has found that exposing patients to forest landscapes through technology improves their health. However, studies on the effects of nature therapy sessions on particularly vulnerable groups that require frequent regular treatment such as patients of chronic kidney disease (CKD) is lacking. This study aims to understand the effects of watching panoramic videos of forest walks through virtual reality (VR) headsets on patients. We also examine the effects of the frequency of virtual exposure to forests on the physiological and psychological parameters of patients undergoing dialysis. Twenty-four dialysis patients with a mean age of 65.11 year underwent a virtual nature intervention over the course of 3 weeks. The intervention consists of 3 numbers of 6-min 360-degree nature videos delivered using VR headsets. We measured heart rate variability (HRV) and heart rate (HR) using continuous electrocardiographic (ECG) monitoring and assessed their emotional states using a questionnaire survey and in-depth interviews. The results showed that the initial 6 min of watching of the panoramic videos through VR headsets resulted in significantly reduced HR and sympathetic nerve activity and increased positive emotional responses. However, repeated VR exposure did not further improve the physiological health of the respondents. Considering these results, the use of VR headsets to watch 6-min nature videos indoors can be used to enhance the positive psychological responses among dialysis and bed-ridden patients. As this study is preliminary, future random controlled trials are needed to compare and determine the best dose, content, and delivery methods of such an intervention.

Public space scenes are being transformed by virtual reality (VR) technology, offering immersive and interactive experiences that redefine how people engage with their surroundings. Through VR simulations, users can explore and interact with virtual public spaces in ways that were previously impossible. From virtual parks and plazas to digital replicas of iconic landmarks, VR technology allows users to experience the ambiance and atmosphere of public spaces from the comfort of their own homes. Moreover, VR enables designers and planners to experiment with different layouts, amenities, and features, facilitating participatory design processes and community engagement. This paper presents a visual design and evaluation framework for public space scenes using virtual reality (VR) technology, enhanced by Virtual Parallel Edge Hashing Computing (VPE-HC). The framework aims to optimize the design and user experience of public spaces by leveraging VR technology to create immersive and interactive simulations. Through simulated experiments and empirical validations, the effectiveness of the VPE-HC-enhanced VR-based design and evaluation process is evaluated. Results demonstrate significant improvements in user satisfaction, engagement, and usability compared to traditional design methods. For instance, users interacting with public space scenes designed using VPE-HC reported a 40% increase in perceived safety and a 25% improvement in overall satisfaction ratings. Additionally, the framework enabled designers to optimize spatial layouts and amenities based on real-time user feedback and performance data, leading to more effective and user-centric design solutions. These findings underscore the potential of VPE-HC in enhancing the visual design and evaluation of public space scenes based on VR technology, facilitating more inclusive and user-friendly urban environments.

This review assesses the risk of a photic-induced seizure in a child during viewing of 3D (binocular 3 dimensional, stereoscopic) movies or games, either on standard video displays or when wearing a virtual reality (VR) headset. Studies published by pediatric epilepsy experts emphasize the low risk of 3D viewing even for children with known photosensitive epilepsy (PSE). The low incidence of PSE is noteworthy because the number of hours devoted to 2D or 3D screen viewing and/or VR headset use by children worldwide has increased markedly over the last decade. The medical literature does not support the notion that VR headset use poses a risk for PSE.

The term "virtual reality" (VR) refers to the interaction of a human being with a simulated world that has been produced via the deployment of computing technology, typically incorporating computer graphics and artificial intelligence. "Virtual" refers to anything that is imagined, whereas "reality" refers to something that is true. Within virtual reality, it is possible for a human to physically handle virtual things or animated objects. Many fascinating applications, such as, make advantage of the three-dimensional settings that are produced via the usage of virtual reality. VR includes training for driving automobiles and aeroplanes, as well as computer games and more applications. The word "augmented reality" is another concept that is sometimes mistaken with virtual reality (VR). For example, augmented reality is the incorporation of virtual items into the physical world. With virtual reality (VR), humans are placed in a simulated three-dimensional world, and they are able to truly experience the sound and sight of the three-dimensional scene, creating the illusion that it is a reality. One example of a virtual world is the game in which the main character in the film created, the kid interacts with it using a virtual reality headset and other equipment. This chapter discusses Virtual Reality main concepts, Virtual Reality experience, characteristics and components of a VR system.

Introduction:The introduction of Virtual Reality (VR) technology has opened up new avenues to delve into daylight and view-out studies, offering a dynamic, controlled, and immersive approach for conducting human-centered experiments. Despite these benefits, existing VR studies in the current view-out research tend to rely on the use of static scenes, typically sourced from tone-mapped HDR photographs or rendered images, which lack the temporal dynamics inherent to real world views. This paper presents a comprehensive methodology for integrating real-time stereoscopic videos into VR to enhance the realism and dynamism of daylight and view-out research.Methods:We utilize a Canon EOS R5 camera equipped with dual fisheye lenses to capture dynamic views-out scenes. The captured footage is converted to an equirectangular format and integrated into Unity3D to create an immersive VR environment. The proposed methodology includes detailed steps for setting up VR experiments, capturing and processing stereoscopic videos, and analyzing participant interactions using physiological data and eye-tracking from a VR headset. Our approach addresses the limitations of static scene simulations by incorporating temporal dynamics and real-time data collection.Results:We provide technical insights, pseudocode, and visual evidence to support the reproducibility and reliability of the proposed workflow. The results demonstrate the potential of VR to significantly improve the accuracy and depth of environmental perception studies, offering a valuable tool for architectural and urban design research. Some of the challenges faced when dealing with the preparation of VR-based human experiments will be addressed, including debugging complexities, scene generation or sequencing issues and problems arising in data collection, specifically within the context of daylight and view-out research. Our aim is to deliver a hands-on workflow, similar in nature to a "contextualized tutorial," that can assist researchers in avoiding common mistakes and refining accuracy in subsequent studies. Future work will focus on validating the VR simulations against real-world conditions and exploring the broader applications of this methodology in different environmental contexts.Conclusion:The implications of our work extend beyond immediate research outcomes, serving as a foundational framework that can grow in utility and application as VR technology advances. In conclusion, we emphasize that our paper stands as a critical resource for researchers dedicated to exploring the intricate interplay between daylight, views, and human perception within the realm of architectural design, offering a method to deepen our understanding as we anticipate future technological breakthroughs.
