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

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.

Independent employment for individuals with intellectual disabilities (ID) is crucial. Virtual reality technology (VRT) offers a controlled and safe training environment, and its psychometric properties need to be well-established if it is used as an educational tool. However, research on educational head-mounted displays (HMDs) as VRT tools for people with intellectual disabilities (ID) remains limited. This study evaluates (1) test-retest reliability, (2) criterion-related validity, and (3) known validity of a VR vocational program for students with ID. Method: A vocational skill-based virtual reality training (VRT) system utilizing a head-mounted display (HMD) was developed through the interdisciplinary collaboration of special education and information engineering experts. A feasibility study design was implemented with 37 technical high school students diagnosed with mild to moderate intellectual disabilities (ID). Social abilities were assessed via the Vineland Adaptive Behavior Scale, and cleaning proficiencies were evaluated using a VR-based "Windows Cleaning" and "Floor Cleaning" training module designed for vocational skills in a store environment. The test-retest reliability, criterion-related validity, and known-group validity of the developed VRT system were subsequently examined. Results: (1) The intraclass correlation coefficient (ICC) is 0.754, and the VR program showed good reliability. (2) A moderate correlation was found between the VRT task total time taken and the Vineland scale, and its criterion-related validity is good. (3) The VRT task total time taken is different between students with mild and moderate ID, and Known-group validity is acceptable. Conclusion: The VRT training program of vocational skills of stores demonstrates acceptable reliability and validity, supporting its use for improving cleaning skills in educational settings.

Virtual reality (VR) entails the use of advanced technologies, including computers and various multimedia peripherals, to produce a simulated (that is, virtual) environment that users perceive as comparable to real world objects and events. In recent years, virtual reality technologies have begun to be used as an assessment and treatment tool in occupational therapy, in part because of the ability to create environments that provide patients with opportunities to engage in meaningful, purposeful tasks that are related to real-life interests and activities. The objective of this study was to determine the suitability and feasibility of using a PC-based, non-immersive, VR system (that is, a system in which the user has a reduced sense of actual presence in and control over the simulated environment) for training individuals with unilateral spatial neglect to cross streets in a safe and vigilant manner. A virtual environment, consisting of a typical city street, was programmed using Superscape's 3D-Webmaster, a 3D web-authoring tool. Twelve subjects, aged 55 to 75 years, participated in the initial feasibility study and, to date, a further eight subjects have participated in the intervention study. Six of the initial subjects and all eight of the intervention subjects had sustained a right hemispheric stroke at least 6 weeks prior to the study. The remaining subjects were healthy age-matched adults who were independently mobile and had no difficulty in crossing streets. The results show that this virtual environment was suitable in both its cognitive and motor demands for the targeted population and indicate that the virtual reality training is likely to prove beneficial to people who have difficulty with crossing streets. The generalizability of these results, and recommendations regarding the use of virtual reality as an occupational therapy intervention, must be substantiated by further studies using a range of VR platforms with people with different cognitive and motor disabilities.

To explore the effectiveness of Virtual Reality Technology in reducing kinesiophobia in people. Kinesiophobia is an important psychosocial factor affecting the pain experience and has a significant negative impact on rehabilitation. Virtual reality technology has been widely used in the treatment of phobias, mental disorders and anxiety disorders. However, the effect of virtual reality technology on people with kinesiophobia has been reported with inconsistent results. A meta-analysis of randomised controlled trials. This study systematically searched PubMed, Web of Science, PsycINFO, CINAHL, Embase, Cochrane Library, Medline, Scopus and four Chinese databases. The standardised mean difference (SMD) was calculated using random-effects models, and the Cochrane Collaboration's tool was used to assess the risk of bias in each study. The PRISMA 2020 checklist provided by the EQUATOR network was used. Eleven randomised controlled trials involving a total of 488 subjects were included. Meta-analysis showed the effect sizes of virtual reality intervention on kinesiophobia (SMD=-0.53, 95% CI [-0.90, -0.17], p= .004). Virtual reality intervention was more effective in reducing kinesiophobia in people with chronic low back pain (SMD=-1.00, 95% CI [-1.71, -0.29], p= .006). Compared with fully immersive virtual reality (SMD=-0.29, 95% CI [-0.62, 0.05], p= 0.09), non-immersive virtual reality was more effective in reducing kinesiophobia (SMD=-0.66, 95% CI [-1.24, -0.09], p= 0.02). Compared with virtual reality intervention alone (SMD=-0.35, 95% CI [-1.40, 0.71], p= 0.52), virtual reality combined with exercise was more effective in reducing kinesiophobia (SMD=-0.59, 95% CI [-0.95, -0.22], p= 0.002). Virtual reality technology has the potential to reduce the degree of kinesiophobia in people. In addition, virtual reality technology was more effective in people with chronic low back pain; non-immersive virtual reality was more effective in reducing kinesiophobia; and virtual reality technology combined with exercise was more effective in reducing kinesiophobia than virtual reality intervention alone. Clinical nursing staff should be encouraged to use virtual reality to speed up patient recovery. However, to achieve immersion and apply this technology to different diseases, more studies are required to provide clearer suggestions. This study suggests that healthcare staff should pay attention to kinesiophobia, and early identification and intervention of kinesiophobia can help patients recover their health and improve the quality of nursing.

Background. Virtual reality technologies can be used to optimize many mental states and develop mental resources. Virtual reality technologies work with the imaginative sphere, recreating images around the subject that are close to those of real people and objects. Methods of psychological correction that work with the imagery are traditionally used to help people relax and relieve stress. Methods. The DAS questionnaire (Differential assessment of states of reduced performance "fatigue-monotony-satiety-stress") (A. Leonova, S. Velichkovska), the Scale for assessing the level of reactive and personal anxiety (C. Spielberg, Y. Khanin), the Assessment of mental activation, interest, emotional tone, tension and comfort (L. Kurgansky and L. Kumiansky), the Questionnaire for assessing acute physical fatigue (A. Leonova), the Assessment of acute mental fatigue (A. Leonova, S. Velichkovska). Kurgansky and L. Kumiansky), Questionnaire for Assessment of Acute Physical Fatigue (A. Leonova), Questionnaire for Assessment of Acute Mental Fatigue (A. Leonova, N. Savicheva), Akiyoshi Kitaoka Optical Illusion Test (a technique aimed at measuring situational fatigue syndrome). Results. The main methods of correction of mental states with the help of virtual technologies are highlighted. The use of virtual reality technologies in the educational sphere is analyzed. It is shown that during the education day, cadets accumulate negative emotional states in the process of classes: fatigue, tension, situational fatigue, monotony. Conclusions. The use of virtual reality technology to immerse a cadet in a virtual space allows you to restore mental resources and delay the development of negative states. For the development of mental resources, the correct selection of virtual realities is of great importance. Thus, watching relaxation-type virtual reality stories leads to a decrease in the level of fatigue, and dynamically stimulating type with the effect of presence leads to a decrease in the level of situational fatigue.

Artificial intelligence involves imitating human thought, consciousness, and other aspects. This is similar to having machine with human brain that can think, produce independently. However, unlike human brain, it has a speed, memory advantage. A virtual reality interactive glove is built using a nine-axis inertial sensor, an artificial intelligence deep learning algorithm. In this research work, Product Design Interaction and Experience Based on Virtual Reality Technology (PDIE-VRT-SCGAN) were proposed. Initially, input gestures data are gathered from the Virtual Reality Experiences (VRE) dataset. The input gestures data is then pre-processed using Multi-Window Savitzky-Golay Filter (MWSGF) to reduce noises, increase overall quality of the gestures data. In order to improving overall user engagement in product design interactions on virtual reality (VR) technology, the pre-processed gestures data are then fed into an adversarial network called a Semi-Cycled Generative Adversarial Network (SCGAN). In general, SCGAN does not express some adaption of optimization strategies for determining optimal parameters to promise exact to improving overall user engagement in product design interactions using VR technology. Therefore, FOX-inspired Optimization (FIO) is proposed to enhance weight parameter of SCGAN method, which precisely improving the user experience in product design interaction. The efficacy of PDIE-VRT-SCGAN method is assessed using a number of performance criteria, including tracking accuracy, frame rate, latency, rendering time, error rate, and user error. The proposed PDIE-VRT-SCGAN method attains 22.36%, 25.42% and 18.17% higher tracking accuracy, 21.26%, 15.42% and 19.27% higher latency, 28.36%, 25.32% and 28.27% higher frame rate compared with existing methods, such as design and implementation of virtual reality interactive product software depend on artificial intelligence deep learning algorithm(DVRI-PS-AI-DL), virtual evaluation system for product designing utilizing virtual reality (VES-PD-VR), and analysis of unsatisfying user experiences with unmet psychological needs for virtual reality exergames utilizing deep learning approach (AUUE-UP-VRE-DLA) respectively.
