This paper investigates the potential of the Gamified Metaverse as a platform for promoting library services. The study compares the effectiveness of a traditional library program with a Metaverse- based library program in terms of knowledge acquisition and library anxiety. The research also examines students' perceptions of implementing gamification within the context of the Gamified Metaverse platform. A mixed-methods approach was adopted, including pre- and post-test analysis, statistical analysis, and qualitative data collection. The results indicate that both the traditional and Metaverse-based library programs effectively increased the participants' knowledge, with no significant difference between the two approaches. However, the Metaverse-based program was found to be less effective in facilitating interaction with librarians and reducing library anxiety. Additionally, students expressed positive perceptions of implementing gamification in the Gamified Metaverse platform, finding it engaging and motivating. These findings contribute to the understanding of the effect of the Metaverse as a tool for promoting library services and enhancing knowledge acquisition. However, it is not as effective in reducing library anxiety, particularly in terms of interaction with librarians and staff. It should be noted that the platform may have limitations such as high costs and potential side effects of virtual reality, making it more suitable as an additional tool for promoting library services, taking into account its feasibility and potential benefits for specific student populations and larger libraries.

Digital technologies such as augmented reality (AR) and virtual reality (VR) offer businesses an opportunity to create a competitive advantage by providing a unique customer experience across the customer's pre-purchase, purchase, and post-purchase journey. Several businesses have engaged with these technologies, yet, South African businesses are slow adopters. A qualitative study was conducted with AR and VR developers to determine how businesses can use AR and VR technologies to enhance their customer experience. Additionally, the study aimed to identify the factors contributing to and hindering the adoption of AR and VR technologies. The findings indicate that these technologies are mainly used for (1) marketing and (2) training purposes, enabling product customization, enhanced brand experience, and improved communication. Several factors contributing to adopting these technologies were identified, such as improved marketing campaigns, reduced training risks, reinforcing best practices, identifying and managing potential hazards, and offering simulations of real-life events. The factors that hinder the adoption include high cost, data usage, customer adoption, and lack of high-quality user experience designers. The findings of this study offer several practical contributions to assist businesses in the decision to implement and engage with these technologies. [ABSTRACT FROM AUTHOR]

Astronaut training is complex due to its specific infrastructure and equipment requirements, which are often costly. Immersive technologies can simulate entire environments, allowing for interactive user experiences. Previous research has confirmed the effectiveness of immersive technologies in training and learning. However, simulations alone are insufficient; participants must also engage with vehicles, machinery, and spacecraft systems to understand their impact on the environment and adjacent objects. This study develops four scenarios within three modules, inspired by NASA and ESA astronaut training programs. The first module presents a theoretical scenario using mixed reality (MR), incorporating topics from ESA's training modules. The second module offers two practical scenarios: an ISS emergency simulation that includes Hohmann transfer and circular motion concepts, and a spacewalk for repair tasks. In these scenarios, digital twins of the ISS propulsion and navigation systems, as well as a spacesuit, were created. The third module simulates a spacecraft launch, utilizing 3D models from SpaceX's Falcon Heavy and digital twins of its propulsion and navigation systems. Participants interacted with the digital twins and scenarios, generating data that was stored and analyzed against the ISS dataset from the Jet Propulsion Laboratory (JPL) and telemetry from the SpaceX Falcon Heavy launch. In this work's initial phase, the main objective was to assess whether digital twins could be integrated with immersive technologies for effective training. A mean squared error metric was employed to compare the digital twins with the physical object data, confirming the alignment of the developed digital twins with the actual systems, thereby validating their utility for astronaut training. • Mixed reality and digital twins can be used to improve astronaut's training. • Mixed reality scenarios are a safe way to learn and train about a specific topic. • Mixed reality foster training experiences: Promoting creative problem-solving skills. • Digital Twins enhances immersive technologies: Leveraging digital twins capacities for immersive training.

Background: Virtual reality (VR), augmented reality (AR) and mixed reality (MR) have sparked recently in improving the effectiveness of teacher education. However, there is a lack of review regarding the utilisation of these technologies in this field. These three technologies, namely VR, AR and MR, can be collectively referred to as extended reality (XR) (as mentioned in reference Tang et al., 2022). Objectives: Remarkably, the utilisation of XR‐based technologies in teacher education needs to be explored. Moreover, research questions related to the training objectives, methodological features, and the effects of XR‐based teacher education remain unanswered. Methods: To this end, the present study conducted a systematic review to analyse 52 articles from six databases (including Web of Science, Scopus, IEEE Xplore, ERIC, ScienceDirect, and ACM Digital Library). Results: The results indicate that XR technologies have been primarily used to train teachers' procedural knowledge, for instance, classroom management. Furthermore, most studies have primarily focused on pre‐service teachers (PSTs) rather than in‐service teachers and utilised small sample sizes, with VR emerging as the most frequently employed tool. Finally, the majority of the studies reported that XR‐based training affected teachers positively. Conclusions: It urges researchers and developers to consider theory‐driven training design, which increases the potential to better understand what features of XR promote in‐service teachers' and PSTs' learning and how they do so. This article additionally conducts a SWOT (strengths, weaknesses, opportunities, and threats) analysis of XR‐based teacher education to offer more insightful recommendations and foster further discussion. Lay Description: What is already known about this topic: Numerous empirical studies have shown the great potential of virtual reality (VR), augmented reality (AR) and mixed reality (MR) technologies utilised in teacher education.This rapidly growing field calls upon a synthesis of the use of extended reality (XR) technologies in teacher education. What this paper adds: Presents a systematic review of XR‐based teacher education, which provides a thorough overview of how previous research utilised XR technologies to promote teacher education.Conducted a SWOT analysis and pointed out the strengths, weaknesses, opportunities, and threats of XR‐based teacher education. Implications for practice and/or policy: A depth of understanding of previous research on this topic may enable educators to better plan and promote teacher education programs.It can guide researchers to optimise the multisensory immersion and interactivity of the virtual systems and platforms and develop suitable materials and tasks to be used in such learning environments.

Background Augmented reality (AR) and virtual reality (VR)—termed mixed reality—have shown promise in the care of operative patients. Currently, AR and VR have well-known applications for craniofacial surgery, specifically in preoperative planning. However, the application of AR/VR technology to other reconstructive challenges has not been widely adopted. Thus, the purpose of this investigation is to outline the current applications of AR and VR in the operative setting. Methods The literature pertaining to the use of AR/VR technology in the operative setting was examined. Emphasis was placed on the use of mixed reality technology in surgical subspecialities, including plastic surgery, oral and maxillofacial surgery, colorectal surgery, neurosurgery, otolaryngology, neurosurgery, and orthopaedic surgery. Results Presently, mixed reality is widely used in the care of patients requiring complex reconstruction of the craniomaxillofacial skeleton for pre- and intraoperative planning. For upper extremity amputees, there is evidence that VR may be efficacious in the treatment of phantom limb pain. Furthermore, VR has untapped potential as a cost-effective tool for microsurgical education and for training residents on techniques in surgical and nonsurgical aesthetic treatment. There is utility for mixed reality in breast reconstruction for preoperative planning, mapping perforators, and decreasing operative time. VR has well- documented applications in the planning of deep inferior epigastric perforator flaps by creating three-dimensional immersive simulations based on a patient's preoperative computed tomography angiogram. Conclusion The benefits of AR and VR are numerous for both patients and surgeons. VR has been shown to increase surgical precision and decrease operative time. Furthermore, it is effective for patient-specific rehearsal which uses the patient's exact anatomical data to rehearse the procedure before performing it on the actual patient. Taken together, AR/VR technology can improve patient outcomes, decrease operative times, and lower the burden of care on both patients and health care institutions. [ABSTRACT FROM AUTHOR]

This evolution promises enhanced accuracy, expanded training opportunities, and improved surgical planning capabilities. [ABSTRACT FROM AUTHOR]

Abstract\nPRACTICING POINTSPurpose: Virtual interactive 3-dimensional models (VI3DM) and immersive virtual reality are implemented in medical education and surgical training. VI3DM allow learners to view and interact with a virtual 3D object and help in conceptualising learning objectives that demand high cognitive and visuo-spatial skills. However, the effects of VI3DM in medical education are unknown. We aimed to determine whether VI3DM are helpful in conceptualising complex anatomical structures. Materials and methods: We included 5 specimens, which were assessed by 200 first-year medical students categorised into experimental (n = 100) and control (n = 100) groups using a systemic randomisation method after matching for age and sex. The experimental group was given VI3DM as interventional learning resources while the control group was given 2-dimensional photographs as conventional learning resources for self-directed learning for 30 minutes. Participants completed a questionnaire before and after the learning session to assess their knowledge related to external features, attachments, and relations of anatomical specimens. Results: The scores of the experimental group improved significantly in the post-test compared to those of the control group for all 5 specimens included in the study (p < 0.05, confidence interval = 95%, unpaired student’s t-test). Conclusions: VI3DM can help conceptualise external features, attachments, and relations of anatomical structures.VI3DM allow interaction with and manipulation of 3D images of anatomical specimens on digital screens, web applications, mobile applications, and head mounted devices.Conceptualisation of anatomical structures requires processing of high cognitive and visuo-spatial information which can be eased by VI3DM.The anatomy can be visualised in high quality using digital 3D technology, which results in good perception of the third dimension and effectively increases the post-test score compared to the conventional method of learning, with higher engagement and satisfaction of the learners.Digital 3D models improve learners’ engagement and compliance, specifically when the presented digital 3D models are interactive.

The study of consciousness has developed well-controlled, rigorous methods for manipulating and measuring consciousness. Yet, in the process, experimental paradigms grew farther away from everyday conscious and unconscious processes, which raises the concern of ecological validity. In this review, we suggest that the field can benefit from adopting a more ecological approach, akin to other fields of cognitive science. There, this approach challenged some existing hypotheses, yielded stronger effects, and enabled new research questions. We argue that such a move is critical for studying consciousness, where experimental paradigms tend to be artificial and small effect sizes are relatively prevalent. We identify three paths for doing so—changing the stimuli and experimental settings, changing the measures, and changing the research questions themselves—and review works that have already started implementing such approaches. While acknowledging the inherent challenges, we call for increasing ecological validity in consciousness studies. In this perspective, Mudrik et al. call for more naturalistic studies of consciousness, given the artificial nature of most experimental manipulations. Despite the entailed challenges, they argue that this will increase ecological validity, generate new questions, and yield stronger effects. [ABSTRACT FROM AUTHOR]

This study investigates the impact of integrating Building Information Modeling (BIM) technologies with Virtual and Augmented Reality (VR-AR) in didactic applications within the AECO (Architecture, Engineering, Construction, and Operations) field. To address this gap, a systematic literature review (SLR) analyzed 30 primary studies, providing a comprehensive overview for teachers and researchers interested in a deeper exploration of the area. The results indicate that the educational implementation of BIM VR-AR has garnered the interest of researchers across various contexts and applications, fostering novel forms of communication and representation. Positive outcomes are notable in terms of motivation and spatial cognitive skills development. In this context, avatar mapping and presence in virtual environments are closely linked to immersion, social presence, and cognitive load. However, challenges such as teacher and student training, costs, interoperability, and device usability persist. The emergence of mobile immersive VR technologies shows promise in mitigating some of these barriers, contributing to realizing the didactic potential of these technologies in STEM (Science, Technology, Engineering, and Mathematics) education.

Large-scale furniture production involves complex manufacturing processes and methods. However, Taiwanese schools face limitations in terms of space and equipment, restricting students from engaging in furniture prototype creation or small-batch production. As a result, students often struggle to grasp practical aspects of large-scale furniture production, leading to a partial understanding of manufacturing processes and methods. To bridge this gap, this study introduces Augmented Reality (AR) technology and miniaturized furniture production lines in a school’s woodshop. AR can be used to guide students through miniaturized production stages, emphasizing semi-automated furniture production features. Additionally, Virtual Reality (VR) technology is combined to provide an immersive experience of real-world, large-scale furniture production, allowing students to understand processing scenarios and conditions in facilities of other countries. In an experiment involving 30 first-year students, an experimental group (15 participants) received mixed AR and VR instruction, while a control group (15 participants) received traditional teaching methods. Findings reveal that AR and VR integration enhanced students’ comprehension of differences between the school workship and overseas large-scale furniture production facilities. This strategy improved their furniture production knowledge, and fostered adaptability to various production conditions and methods. [ABSTRACT FROM AUTHOR]

Video see‐through (VST) head‐mounted displays (HMDs) reconstruct the physical world using outward‐facing cameras and depth sensors. One of the major challenges for VST HMDs is the geometric distortion of the physical pass‐through content. In this study, we present the experimental setup and metrology for VST geometric distortion measurement on single‐camera and dual‐camera VST HMDs. The VST geometric distortion is compared to the digital distortion by the HMD. Finally, we investigate the impacts of camera misalignment and depth distance on VST geometric distortion without and with angular‐based distortion correction. The results demonstrate that camera misalignment with respect to the eye position is the primary root cause for the distortion. Dual‐camera setup is necessary to minimize the VST geometric distortion by placing the cameras close to the eye positions. Although distortion correction can partially mitigate VST geometric distortion in a 2D plane, it remains a challenge for VST distortion correction at multiple depth distance in the 3D space. The method and findings presented of this study may provide guidelines for evaluation of spatial accuracy on VST HMDs and hardware design. [ABSTRACT FROM AUTHOR]

Collaboration in extended reality (XR) environments presents complex challenges that revolve around how users perceive the presence, intentions, and actions of their collaborators. This paper delves into the intricate realm of group awareness, focusing specifically on workspace awareness and the innovative visual cues designed to enhance user comprehension. The research begins by identifying a spectrum of collaborative situations drawn from an analysis of XR prototypes in the existing literature. Then, we describe and introduce a novel classification for workspace awareness, along with an exploration of visual cues recently employed in research endeavors. Lastly, we present the key findings and shine a spotlight on promising yet unexplored topics. This work not only serves as a reference for experienced researchers seeking to inform the design of their own collaborative XR applications but also extends a welcoming hand to newcomers in this dynamic field.

Holographic Optical Elements (HOEs) employ refractive index (RI) modulation to manipulate light, establishing their widespread application in augmented and virtual reality technologies. Despite significant strides in HOEs' fabrication, a comprehensive 3D examination and measurement of these elements remain largely unexplored. This study targets this void by conducting an in‐depth exploration of the 3D RI distributions of volume holographic gratings (VHGs), a quintessential representative of HOEs. Direct tomographic measurements of the 3D RI distributions within millimeter‐scale VHGs are performed at a spatial resolution of 156 nm × 156 nm × 1.2 µm and an RI precision of 2×10−4. This level of precision facilitates a systematic high‐resolution characterization of VHGs. The findings present a substantial evolution from traditional measurement techniques and promise to considerably advance the evaluation of intricate HOE structures and refine the corresponding fabrication processes.

As the field of three-dimensional (3D) visualization rapidly advances, how healthcare professionals perceive and interact with real and virtual objects becomes increasingly complex. Lack of clear vocabulary to navigate the changing landscape of 3D visualization hinders clinical and scientific advancement, particularly within the field of radiology. In this article, we provide foundational definitions and illustrative examples for 3D visualization in clinical care, with a focus on the pediatric patient population. We also describe how understanding 3D visualization tools enables better alignment of hardware and software products with intended use-cases, thereby maximizing impact for patients, families, and healthcare professionals.

Objective: This study used a virtual environment to examine how older and younger pedestrians responded to simulated augmented reality (AR) overlays that indicated the crossability of gaps in a continuous stream of traffic. Background: Older adults represent a vulnerable group of pedestrians. AR has the potential to make the task of street-crossing safer and easier for older adults. Method: We used an immersive virtual environment to conduct a study with age group and condition as between-subjects factors. In the control condition, older and younger participants crossed a continuous stream of traffic without simulated AR overlays. In the AR condition, older and younger participants crossed with simulated AR overlays signaling whether gaps between vehicles were safe or unsafe to cross. Participants were subsequently interviewed about their experience. Results: We found that participants were more selective in their crossing decisions and took safer gaps in the AR condition as compared to the control condition. Older adult participants also reported reduced mental and physical demand in the AR condition compared to the control condition. Conclusion: AR overlays that display the crossability of gaps between vehicles have the potential to make street-crossing safer and easier for older adults. Additional research is needed in more complex real-world scenarios to further examine how AR overlays impact pedestrian behavior. Application: With rapid advances in autonomous vehicle and vehicle-to-pedestrian communication technologies, it is critical to study how pedestrians can be better supported. Our research provides key insights for ways to improve pedestrian safety applications using emerging technologies like AR. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to determine the extent of virtual reality (VR)/augmented reality (AR) adoption in university libraries in Indonesia and identify librarians' views of library readiness. The assessment centers on two crucial dimensions: library readiness, gauged by commitment and efficacy, and librarian readiness, appraised through cognitive and affective aspects. Design/methodology/approach: The research features a survey-based quantitative method. A sample of 259 librarians from university libraries, all members of the Indonesian Higher Education Library Forum, responded to the online survey. Findings: Indonesian university libraries, especially in Central Java, express strong interest in VR/AR despite low current adoption. Librarians believe in their commitment and efficacy for adoption, with improvements needed in budget procurement and human resources. Librarians are optimistic about innovating academic activities with VR/AR, despite concerns about collaboration, data governance and human resource insecurity. The research underscores the simultaneous influence of librarians' and libraries' readiness on VR/AR adoption, emphasizing their interconnectedness and mutual support within library management. Practical implications: There are practical implications for library institutions in Indonesia in terms of understanding the attendant opportunities and challenges when preparing organizational ecosystems. These findings provide a broad overview of VR/AR adoption in university libraries in Indonesia and contribute to understanding the specific needs and interests of universities in Indonesia considering adopting VR/AR. In addition to preparing adequate infrastructure, libraries should ensure the availability of adequate human resources. Originality/value: In the Indonesian context, this study, to the best of the authors' knowledge, makes the first attempt to examine the librarian's view as part of library management to face the dilemmas that may arise during the adoption of VR/AR despite university libraries' commitment and efficacy to enable this technology. This research also identifies librarians' cognitive and affective readiness as individual characteristics and resources able to influence adequate adoption. [ABSTRACT FROM AUTHOR]

Immersive journalism is a recent field of research focusing on digital technologies such as augmented reality (AR), 360° video, and virtual reality (VR). This research analyzed 69 academic articles published in the Web of Science from January 1, 2010, to December 31, 2021, using a systematic review of scientific literature (SLR). The prevalence of media effects and quantitative methodologies in investigating immersive journalism was demonstrated. The corpus analysis shows the recurrence of some key macro-concepts. We propose grouping these macro-concepts into affordances (presence, embodiment, and interactivity) and gratifications (comprehension, credibility, emotional engagement, and empathy), which affect in different extents the cognition, affectivity, and behavior of the users. This review highlights the need to expand and combine different theories and methodologies. Another important recommendation is to create specific frameworks for analyzing immersive news stories and examining their various narrative and aesthetic characteristics during both production and post-production. This article discusses the ethical and normative concerns of journalism in relation to current and future research in VR. [ABSTRACT FROM AUTHOR]

Digital game technologies, that is, games and emerging game-based applications, are pervasively spread in society as a means of entertainment, education and exercise, amongst other uses. With this popularity, attention has been directed towards the accessibility of these technologies to people with disabilities to ensure equity, equal access to opportunities and realize earnings from a significant customer group. This study investigates: How is the attention of academic game accessibility research divided across game technologies, disability categories and use domains? And where is attention needed? To answer these questions, I conducted a review of research (162 manuscripts) on game technologies' accessibility published between 2016 and 2020, inclusive. The reviewed literature appears to have a utility focus (e.g. on education and health management) that relatively de-emphasizes the importance of game accessibility for entertainment or fun purposes. Auditory, motor and mobility disabilities, and emerging gamification, exergames, virtual reality (VR) and augmented reality (AR) are especially under researched in the academic domain.

Virtual reality (VR) gaming (VRG) captures, examines, analysis, and renders the game data virtually instead of the users’ devices over efficient networks. E.g., VR is crucial in visually guided surgery and manifold therapies. Video Quality Assessment (VQA) helps VRG software and devices execute high-quality inputs/outputs. This paper debates VRG processes, environments, VQA metrics, Quality of Experience (QoE), platforms, current methods, tools, use in medicine, existing operational gains/challenges, and highlights future directions.

Objectively examine the effect of 3D-Augmented Reality anatomic review on craniotomy planning among neurosurgical residents as it pertains to craniotomy size, skull positioning, and knowledge of significant anatomic relationships. Postgraduate year 1-7 neurosurgery residents were instructed to review standard 2D radiographs, pin a skull, and tailor a craniotomy for 6 different lesions and case vignettes. Participants then reviewed the lesion in a 3D-augmented reality (AR) environment, followed by repeating the craniotomy station for a variety of lesion types and locations (superficial, subcortical, deep, skull base). Quiz with case-specific anatomic and surgical questions followed by an exit survey for qualitative impressions. Eleven of thirteen eligible residents participated. Skull position significantly changed in 5 out of 6 cases after 3D-AR view (P < 0.05, 20° angular adjustment). No significant change in incision length or craniotomy size. Subgroup analysis of junior versus senior residents revealed that craniotomy size was significantly altered in 2 out of 6 cases. Qualitative testimonials (Likert scale 5 = strongly agree) reported a change in craniotomy approach after 3D-review (3.5), improved appreciation of anatomy (4.2), increased confidence in surgical approach (4.33 junior residents, 3.5 senior residents), smaller incision (3.5 junior residents, 1.75 senior residents), better appreciation of white matter tracts (4.6). The augmented reality platform offers a medium to examine surgical planning skills. Residents uniformly appreciated 3D-AR as a valuable tool for improving appreciation of critical anatomic structures and their relationship to lesional pathology. 3D-AR review significantly altered skull positioning for various lesions and craniotomy approaches, particularly among junior residents.

Neurosurgical technologies have become increasingly more adaptive, featuring real-time and patient-specific guidance in preoperative, intraoperative, and postoperative settings. This review offers insight into how these integrative innovations compare with conventional approaches in spine surgery, focusing on machine learning (ML), artificial intelligence, augmented reality and virtual reality, and spinal navigation systems. Data on technology applications, diagnostic and procedural accuracy, intraoperative times, radiation exposures, postoperative outcomes, and costs were extracted and compared with conventional methods to assess their advantages and limitations. Preoperatively, augmented reality and virtual reality have applications in surgical training and planning that are more immersive, case specific, and risk-free and have been shown to enhance accuracy and reduce complications. ML algorithms have demonstrated high accuracy in predicting surgical candidacy (up to 92.1%) and tailoring personalized treatments based on patient-specific variables. Intraoperatively, advantages include more accurate pedicle screw insertion (96%–99% with ML), enhanced visualization, reduced radiation exposure (49 μSv with O-arm navigation vs. 556 μSv with fluoroscopy), increased efficiency, and potential for fewer intraoperative complications compared with conventional approaches. Postoperatively, certain ML and artificial intelligence models have outperformed conventional methods in predicting all postoperative complications of >6000 patients as well as predicting variables contributing to in-hospital and 90-day mortality. However, applying these technologies comes with limitations, such as longer operative times (up to 35.6% longer) with navigation, dependency on datasets, costs, accessibility, steep learning curve, and inherent software malfunctions. As these technologies advance, continuing to assess their efficacy and limitations will be crucial to their successful integration within spine surgery. [ABSTRACT FROM AUTHOR]

Purpose: This study delves into the psychological processes underlying sport fans' post-purchase innovativeness behaviour. This exploratory research aims to establish a theoretical framework that elucidates the formation of sport fans' word-of-mouth (WOM) behaviours, particularly emphasising the structural relationship between motivated consumer innovativeness and satisfaction in using AR live-streaming services. Design/methodology/approach: Utilising an online survey and convenience sampling, the study garnered a total of 243 usable responses from three online baseball fan communities in South Korea. Confirmatory factor analysis was employed to assess the psychometric properties of the constructs. Subsequently, a structural equation model was used to probe the influence of motivated consumer innovativeness on WOM, with a particular focus on the mediating role of satisfaction. Findings: Three dimensions of motivated sport fans innovativeness – functional, hedonic and cognitive – showed a positive association with WOM, partly mediated by satisfaction. In contrast, socially motivated sport fans innovativeness did not directly lead to WOM but influenced it solely through satisfaction. The full mediating role of satisfaction in the relationship between socially motivated fans innovativeness and WOM was found. Originality/value: This research stands out as one of the scant studies exploring motivated sport fans innovativeness in the context of AR live sport streaming. The findings not only corroborate but also augment the extant literature by empirically confirming that three dimensions of motivated fans innovativeness, coupled with satisfaction, are pivotal antecedents to WOM intention.

This exploratory study uses epistemic network analysis (ENA) to examine the use of extended reality (XR) technologies embedded in post-secondary classes, one in a traditional setting and the other a place-based setting, to examine climate change while utilizing a socioscientific issues (SSI) approach. One group used a virtual reality (VR) application on their smartphones in a traditional class setting to explore four different locations on the Outer Banks of North Carolina, USA (OBX). A second group used an augmented reality (AR) application on their smartphones while visiting the same four locations. Qualitative data was collected after each experience. Analysis of each group's networks indicated that both forms of technology engaged students in the SSI and were beneficial to their learning. However, differences in the networks revealed that virtual reality students made stronger connections between the technology, the physical impacts of climate change, and the political/socioeconomic aspects of climate change. In contrast, the augmented reality students made stronger connections between the technology and learning in general. Implications for practice and future research will be discussed.

Episodic Memory (EM) is the neurocognitive capacity to consciously recollect personally experienced events in specific spatio-temporal contexts. Although the relevance of spatial and temporal information is widely acknowledged in the EM literature, it remains unclear whether and how EM performance and organisation is modulated by self-motion, and by motor- and visually- salient environmental features (EFs) of the encoding environment. This study examines whether and how EM is modulated by locomotion and the EFs encountered in a controlled lifelike learning route within a large-scale building. Twenty-eight healthy participants took part in a museum-tour encoding task implemented in walking Augmented Reality (AR) and stationary Virtual Reality (VR) conditions. EM performance and organisation were assessed immediately and 48-hours after trials using a Remember/Familiar recognition paradigm. Results showed a significant positive modulation effect of locomotion on distinctive EM aspects. Findings highlighted a significant performance enhancement effect of stairway-adjacent locations compared to dead-end and mid-route stimuli-presentation locations. The results of this study may serve as design criteria to facilitate neurocognitive rehabilitative interventions of EM. The underlying technological framework developed for this study represents a novel and ecologically sound method for evaluating EM processes in lifelike situations, allowing researchers a naturalistic perspective into the complex nature of EM.

Background: Recent technological advancements present promising opportunities to enhance the frequency and objectivity of functional assessments, aligning with recent stroke rehabilitation guidelines. Within this framework, we designed and adapted different manual dexterity tests in extended reality (XR), using immersive virtual reality (VR) with controllers (BBT-VR-C), immersive VR with hand-tracking (BBT-VR-HT), and mixed-reality (MD-MR). Objective: This study primarily aimed to assess and compare the validity of the BBT-VR-C, BBT-VR-HT and MD-MR to assess post-stroke manual dexterity. Secondary objectives were to evaluate reliability, usability and to define arm kinematics measures. Methods: A sample of 21 healthy control participants (HCP) and 21 stroke individuals with hemiparesis (IHP) completed three trials of the traditional BBT, the BBT-VR-C, BBT-VR-HT and MD-MR. Content validity of the different tests were evaluated by asking five healthcare professionals to rate the difficulty of performing each test in comparison to the traditional BBT. Convergent validity was evaluated through correlations between the scores of the traditional BBT and the XR tests. Test-retest reliability was assessed through correlations between the second and third trial and usability was assessed using the System Usability Scale (SUS). Lastly, upper limb movement smoothness (SPARC) was compared between IHP and HCP for both BBT-VR test versions. Results: For content validity, healthcare professionals rated the BBT-VR-HT (0[0–1]) and BBT-MR (0[0–1]) as equally difficult to the traditional BBT, whereas they rated BBT-VR-C as more difficult than the traditional BBT (1[0–2]). For IHP convergent validity, the Pearson tests demonstrated larger correlations between the scores of BBT and BBT-VR-HT (r = 0.94;p < 0.001), and BBT and MD-MR (r = 0.95;p < 0.001) than BBT and BBT-VR-C (r = 0.65;p = 0.001). BBT-VR-HT and MD-MR usability were both rated as excellent, with median SUS scores of 83[57.5–91.3] and 83[53.8–92.5] respectively. Excellent reliability was found for the BBT-VR-C (ICC = 0.96;p < 0.001), BBT-VR-HT (ICC = 0.96;p < 0.001) and BBT-MR (ICC = 0.99;p < 0.001). The usability of the BBT-VR-C was rated as good with a median SUS of 70[43.8–83.8]. Upper limb movements of HCP were significantly smoother than for IHP when completing either the BBT-VR-C (t = 2.05;p = 0.043) and the BBT-VR-HT (t = 5.21;p < 0.001). Conclusion: The different XR manual tests are valid, short-term reliable and usable tools to assess post-stroke manual dexterity.

The holistic growth and psychological well-being of people with special needs and disabilities remain high on the priority agenda for sustainable and inclusive education. Digital well-being technologies and especially "smart technologies", are ready to revolutionize mental health interventions by meeting trainees' needs and providing them with more positive and transformative mental, emotional, and social experiences. Μeta-skills refer to a set of consciousness-raising competences that incorporate meta-cognitive, social–emotional, and motivational attributes, allowing individuals to intentionally achieve a state of optimal functioning. Although positive psychology and well-being technologies are considered promising intervention approaches, there is less knowledge regarding the effectiveness of such interventions among people with special needs and disabilities, especially in the crucial domain of meta-skills development. Thus, the current systematic review aims to examine positive psychology strategies as well as the synergy with well-being technologies in the development of metacognition, emotional intelligence, and motivation meta-skills in populations with special training needs and disabilities. The PRISMA methodology was utilized to answer the research questions. A total of forty-nine studies met the inclusion criteria. The results indicated that positive psychology strategies improved a wide range of meta-skills, including self-regulation, emotional control, behavioral control, inhibition control, self-awareness, intrapersonal skills, interpersonal skills, adaptation, goal setting, and self-compassion. Artificial intelligence tools, wearables, smart applications, immersive technologies (virtual and augmented reality), neurofeedback and biofeedback technologies, as well as digital games were found to effectively assist such training programs. The results of the current review may provide positive feedback in the discussion about digitally-aided mental health interventions for training the meta-skills of mental and emotional health.

Postoperative pain after knee arthroplasty (TKA) is a reality that continues to be experienced today. Recently, virtual reality (VR) has demonstrated effectiveness in the management of pain. Our aim was to review the original controlled trials evaluating the effectiveness of VR for pain management and quality of life after TKA. Six databases were searched for articles published from inception to September 2023, following (PRISMA) guidelines. The methodological quality was assessed using the Risk of Bias tool for Randomized Trials (ROB2). Five RCTs were included in the systematic review, and four of them in the meta-analysis. The effectiveness of VR for short term pain relief was superior compared to the control (MD = −0.8 cm; CI 95%: −1.3 to −0.4; p < 0.001). VR showed a greater effect on the secondary outcomes of WOMAC (MD = −4.6 points; CI 95%: −6.5 to −2.6, p < 0.001) and the HSS scale (MD = 6.5 points; CI 95%: 0.04 to 13.0, p = 0.049). However, no differences were found in the effect on the ROM between groups (MD = 3.4 grades; CI 95%: −6.0 to 12.8, p = 0.48). Our findings suggest that the use of virtual reality during the postoperative period could be an effective non-pharmacological therapy in relieving acute pain, compared to a control intervention, with a very low degree of certainty according to the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE). However, the low methodological quality of the articles limits our findings. [ABSTRACT FROM AUTHOR]

The research is focused on finding ways to develop safe environment design using virtual worlds like Second Life and Metavers and identifying the best opportunities for this. The novelty of the study lies in a wide representative survey of experienced participants in the process of designing a secure environment using virtual tools and obtaining their generalized Delphi assessment of the prospects and optimal capabilities of this process. The survey involved 228 participants from 31 countries. The participants formulated a set of possibilities and patterns of possible development and then gave them an assessment. The results of the study showed that designers and planners tend to distrust the possibilities of modeling and predicting the state of the urban safe environment in virtual spaces and tend to perceive it as a means of creating projects, revealing the imagination and talent of the designer and a space for communication and co-design with the expert community and communities. It was revealed that they see the use of augmented reality for the presentation of real objects in the virtual world and information about objects in the real world as the most promising direction of development.

The concept of immersion has been widely used for the design and evaluation of user experiences. Augmented, virtual and mixed-reality environments have further sparked the discussion of immersive user experiences and underlying requirements. However, a clear definition and agreement on design criteria of immersive experiences remains debated, creating challenges to advancing our understanding of immersive experiences and how these can be designed. Based on a multidisciplinary Delphi approach, this study provides a uniform definition of immersive experiences and identifies key criteria for the design and staging thereof. Thematic analysis revealed five key themes – transition into/out of the environment, in-experience user control, environment design, user context relatedness, and user openness and motivation, that emphasise the coherency in the user-environment interaction in the immersive experience. The study proposes an immersive experience framework as a guideline for industry practitioners, outlining key design criteria for four distinct facilitators of immersive experiences – systems, spatial, empathic/social, and narrative/sequential immersion. Further research is proposed using the immersive experience framework to investigate the hierarchy of user senses to optimise experiences that blend physical and digital environments and to study triggered, desired and undesired effects on user attitude and behaviour.

Background: Given the variety in mitral valve (MV) pathology and associated surgical techniques, extended reality (XR) holds great potential to assist MV surgeons. This review aims to systematically evaluate the currently available evidence investigating the use of XR and associated technologies in MV surgery. Methods: A systematic database search was conducted of original articles and case reports that explored the use of XR and MV surgery in EMBASE, MEDLINE, Cochrane database and Google Scholar, from inception to February 2022. Results: Our search yielded 171 articles, of which 15 studies were included in this review, featuring 328 patients. Two main areas of application were identified: (i) pre-operative planning and (ii) predicting post-operative outcomes. The articles reporting outcomes relating to pre-operative planning were further categorised as exploring themes relevant to (i) mitral annular assessment; (ii) training; (iii) evaluation of surgical technique; (iv) surgical approach or plan and (v) selecting ring size or type. Preoperatively, XR has been shown to evaluate mitral annular pathology more accurately than echocardiography, informing the surgeon about the optimal surgical technique, approach and plan for a particular patient's MV pathology. Furthermore, XR could simulate and aid ring size/type selection for MV annuloplasty, creating a personalized surgical plan. Additionally, XR could estimate the postoperative MV biomechanical and physiological characteristics, predicting and pre-empting post-operative complications. Conclusion: XR demonstrated promising applications for assisting MV surgery, enhancing outcomes and patient-centred care, nevertheless, there remain the need for randomized studies to ascertain its feasibility, safety, and validity in clinical practice.

This study is about the metaverse environment which has recently heard a lot in life. Although many individuals and institutions are interested in metaverse, it is an imaginary future space, and the conceptual framework is not fully drawn. The metaverse is a mix of augmented, virtual, and mixed reality technologies that are predicted to affect our lives over the next decade including our money, possessions, and ownership. So, we examined to forecast metaverse token price using ANN and ANFIS methods. The market value of the five metaverse token firms: opening price, highest value, lowest value, closing price, volume value, and variables, is evaluated between October 17, 2017, and December 15, 2022, by YSA and ANFIS. The ANN method training was carried out using ten hidden layers and the Levenberg–Marquardt algorithm. In the ANFIS method, training was carried out with 100 iterations in a triple mesh structure. At the end of the method training, the training performed with the ANN method was 99.3% successful, and the ANFIS method was 99.1% successful. It is concluded that the model fitness of the R2 values of ANN and ANFIS methods is appropriate at 99.3 and 98.7%, respectively. As a result, ANN and ANFIS methods can be used for the prediction of metaverse token prices for the estimation of financial instruments. ANN and ANFIS are advanced tools for predicting metaverse token prices, with ANFIS having unique features like fuzzy logic. However, using only basic price data is not enough for precise predictions. While the EMA and SMA have less impact, gold (XAU), BTC, ETH, US dollar (USD), Chinese Yuan (CNY), and Brent oil (BRT) are observed to have a moderate impact on determining the market values of metaverse prices. The use of XAU and ETH prices in both ANN and ANFIS methods gives successful results. Especially, we have achieved favorable outcomes when employing the ANN method for analyzing EMA and BTC values. Additionally, we have obtained valuable and successful results by utilizing the ANFIS method for analyzing BRT. Using only opening, highest, lowest, closing prices, and volume values and USD, CNY, BRT, and SMA prices has not demonstrated usefulness in attaining favorable results. The findings of this research indicate that the utilization of the metaverse world has the potential to enhance learning capabilities and motivation, as well as make significant contributions to industrial production and the field of health. However, it is important to note that the existing body of research on the metaverse world remains limited in scope and depth. Users often hold preconceived notions and biases regarding ethical concerns associated with the metaverse world. Additionally, there are significant obstacles that need to be addressed in terms of fulfilling hardware requirements for its implementation. [ABSTRACT FROM AUTHOR]

Mohs micrographic surgery (MMS) is a cornerstone of dermatological practice. Virtual reality (VR) and augmented reality (AR) technology, initially used for entertainment, have entered healthcare, offering real-time data overlaying a surgeon’s view. This paper explores potential applications of VR and AR in MMS, emphasizing their advantages and limitations. We aim to identify research gaps to facilitate innovation in dermatological surgery. We conducted a PubMed search using the following: “augmented reality” OR “virtual reality” AND “Mohs” or “augmented reality” OR “virtual reality” AND “surgery.” Inclusion criteria were peer-reviewed articles in English discussing these technologies in medical settings. We excluded non-peer-reviewed sources, non-English articles, and those not addressing these technologies in a medical context. VR alleviates patient anxiety and enhances patient satisfaction while serving as an educational tool. It also aids physicians by providing realistic surgical simulations. On the other hand, AR assists in real-time lesion analysis, optimizing incision planning, and refining margin control during surgery. Both of these technologies offer remote guidance for trainee residents, enabling real-time learning and oversight and facilitating synchronous teleconsultations. These technologies may transform dermatologic surgery, making it more accessible and efficient. However, further research is needed to validate their effectiveness, address potential challenges, and optimize seamless integration. All in all, AR and VR enhance real-world environments with digital data, offering real-time surgical guidance and medical insights. By exploring the potential integration of these technologies in MMS, our study identifies avenues for further research to thoroughly understand the role of these technologies to redefine dermatologic surgery, elevating precision, surgical outcomes, and patient experiences.

Emerging technological innovations offer the potential for experiential engagement through virtual scenarios, yet the viability of this approach for educational purposes remains significantly underexplored. This study aims to assess the feasibility of Augmented Reality (AR) and Virtual Reality (VR) technologies in providing users with aesthetic experiences when visiting digital exhibitions. A total of 190 students participated in this investigation. The control group visited traditional exhibits at the Palace Museum in Beijing. This group underwent a survey to evaluate their acquired aesthetic experience. In contrast, the experimental group, comprising 96 students, engaged with VR/AR scenarios at the Palace Museum in Beijing. Accordingly, students in the experimental group were also surveyed to evaluate both their aesthetic experiences and, additionally, their user experiences. The survey results unveiled significant distinctions in aesthetic experiences between students in the control and experimental groups. Moreover, there were notable correlations between individual variables related to user and aesthetic experiences within the experimental group. Furthermore, the study revealed disparities in both user and aesthetic experiences among male and female students. The findings have implications for aesthetic education teachers and officials in the context of developing sound strategies for providing aesthetic experiences to their students. This information is also of interest to employees of museums, exhibitions, and other cultural facilities, who are interested in holding or hold digital exhibitions. [ABSTRACT FROM AUTHOR]

Human‐machine interaction(HMI) is extensively employed in various applications such as robotic control and augmented reality/virtual reality. However, HMIs are mainly based on single‐interaction mode, requiring bulky equipment to be worn or sustaining physical contact with the interfaces, resulting in limited interaction efficiency and intelligence. Here, it proposes a novel flexible dual‐mode capacitive sensor using 12 sensing units for touchless and tactile sensing during HMIs, the sensor has a labyrinth‐patterned electrode to improve the performance of proximity sensing and a truncated pyramid‐shaped porous hierarchical dielectric structure to improve the pressure sensing performance. The fabricated dual‐mode sensor is characterized by a high proximity detection range of up to 110 mm, the pressure detection range is from 0 to 200 kPa with a sensitivity of 0.464% kPa−1. Further, the dual‐mode sensor exhibits excellent discrimination between proximity and pressure signals, along with remarkable stability and repeatability. Then, a touchless‐tactile HMI platform is developed for real‐time control of robotics through accurate perception of touchless hand gestures and contact‐pressing interactions. This platform demonstrates the superior dual‐mode sensing performance of the sensor and validates its potential in future intelligent HMI scenarios. [ABSTRACT FROM AUTHOR]

Augmented reality (AR) is a computer graphics technique that creates a seamless interface between the real and virtual worlds. AR usage rapidly spreads across diverse areas, such as healthcare, education, and entertainment. Despite its immense potential, AR interface controls rely on an external joystick, a smartphone, or a fixed camera system susceptible to lighting. Here, an AR‐integrated soft wearable electronic system that detects the gestures of a subject for more intuitive, accurate, and direct control of external systems is introduced. Specifically, a soft, all‐in‐one wearable device includes a scalable electrode array and integrated wireless system to measure electromyograms for real‐time continuous recognition of hand gestures. An advanced machine learning algorithm embedded in the system enables the classification of ten different classes with an accuracy of 96.08%. Compared to the conventional rigid wearables, the multi‐channel soft wearable system offers an enhanced signal‐to‐noise ratio and consistency over multiple uses due to skin conformality. The demonstration of the AR‐integrated soft wearable system for drone control captures the potential of the platform technology to offer numerous human–machine interface opportunities for users to interact remotely with external hardware and software.

AbstractThis article describes a mixed reality visual instruction approach for remote collaboration between a trainee and an expert. The expert authors the visual instructions through a virtual reality interface. The instructions are shown to the trainee overlaid onto the workspace using an augmented reality interface. The approach achieves effectiveness and efficiency by addressing three challenges. First, the expert-authored visual instructions are shown to the trainee by taking into account occlusions with the 3D workspace; Second, in addition to abstract visual instructions implemented by arrows, the expert can also author highly suggestive instructions by depicting the target state of the workspace realistically by selecting, copying, pasting, and repositioning workspace objects; Third, multiple instructions can be concatenated in sequences that the trainee executes on their own, without any additional guidance from the expert; The approach has been evaluated in a controlled user study with three experiments. The experiment verification confirms that compared to the conventional instruction, this approach achieves significantly lower error rates, shorter task completion times, and lower rotation angular errors. Moreover, the approach allows the trainee to execute the entire sequence robustly, without real-time instruction from the expert. [ABSTRACT FROM AUTHOR]

Background: Visuospatial neglect (VSN) is a cognitive disorder after stroke in which patients fail to consciously process and interact with contralesional stimuli. Visual Scanning Training (VST) is the recommended treatment in clinical guidelines. At the moment, several mixed reality versions of Visual Scanning Training (VST) are being developed. The aim of this study was to explore the opinions of end-users (i.e., therapists) on the use of Virtual Reality (VR) and Augmented Reality (AR) in VSN treatment. Methods: Therapists played one VR and two AR Serious Games, and subsequently filled out a questionnaire on User Experience, Usability, and Implementation. Results: Sixteen therapists (psychologists, occupational, speech, and physiotherapists) played the games, thirteen of them evaluated the games. Therapists saw great potential in all three games, yet there was room for improvement on the level of usability, especially for tailoring the games to the patient's needs. Therapists' opinions were comparable between VR and AR Serious Games. For implementation, therapists stressed the urgency of clear guidelines and instructions. Discussion: Even though VR/AR technology is promising for VSN treatment, there is no one-size-fits-all applicability. It may thus be crucial to move towards a plethora of training environments rather than a single standardized mixed reality neglect treatment. Conclusion: As therapists see the potential value of mixed reality, it remains important to investigate the efficacy of AR and VR training tools. [ABSTRACT FROM AUTHOR]

Some organisms often use adhesive setae to manipulate objects or communicate critical signals for survival through subtle surface‐transmitted vibrations, along with locomotion and long‐term adherence. Inspired by this phenomenon, the spatially selective vibration‐transmitting electronics of a multi‐pixelated electroactive‐actuating adhesive patch coupled with small adhesive architectures are presented. Here, diving beetle‐like small dense hairs possessing concave cavities are introduced to obtain high adaptability on various non‐flat surfaces in dry or wet conditions. Based on the versatile vibration‐transmitting platform, the ensuing lightweight, spatially‐selective, switchable‐adhesive device is demonstrated to effectively manipulate multiple objects simultaneously, thus overcoming the limitations of existing monotonous transportation devices. In addition, the electronics can be applied to the stretchable skin‐conforming haptic interface with high breathability and repeatable attachment capability, capable of recognizing complex outward textures of virtual objects. This skin‐adaptive haptic electronics can amplify the tiny vibrotactile feedback from the diverse surface textures of virtual creatures due to its possession of bioinspired architectures at the human–machine interface. Here, the stably encapsulated device is integrated with machine learning‐based comprehension for reproducible expression. Therefore, this technology offers promise in virtual reality and augmented reality applications. [ABSTRACT FROM AUTHOR]

The understanding of the metaverse is currently expanding, and several interpretations and implementations may be present. The many metaverse iterations have distinct components and capabilities, which have the potential to evolve and enhance over time in tandem with technological advancements and evolving user requirements. The metaverse has emerged as a widely discussed subject of public interest, with individuals and organizations alike contemplating its potential applications. However, a prevailing misperception persists over its fundamental comprehension. The concept of the metaverse is often misconstrued as solely referring to a virtual world; nevertheless, it encompasses more than simply a virtual realm. Three other categories can be classified as constituting the metaverse. The metaverse encompasses four distinct categories, each characterized by unique aspects that may or must diverge from one another. The elements play a crucial role in the development of any metaverse kind. This work aims to provide a valuable contribution by offering a comprehensive analysis of the constituent features of various metaverse types. Its purpose is to assist anyone interested in studying or implementing a certain metaverse type by fostering a deeper understanding of its core aspects. [ABSTRACT FROM AUTHOR]

The search strategy used Medical Subject Headings (MeSH) terms, including "MeSH (Artificial intelligence)," "Spine" AND "Spinal" filters, in the last 10 years, and English--from January 1, 2013, to October 31, 2023. In total, 442 articles fulfilled the first screening criteria. A detailed analysis of those articles identified 220 that matched the criteria, of which 11 were considered appropriate for this analysis after applying the complete inclusion and exclusion criteria. In total, 11 studies met the eligibility criteria. Analysis of these studies revealed the types of artificial intelligence-assisted spine surgery. No evidence suggests the superiority of assisted spine surgery with or without artificial intelligence in terms of outcomes. In terms of feasibility, accuracy, safety, and facilitating lower patient radiation exposure compared with standard fluoroscopic guidance, artificial intelligence-assisted spine surgery produced satisfactory and superior outcomes. The incorporation of artificial intelligence with augmented and virtual reality appears promising, with the potential to enhance surgeon proficiency and overall surgical safety.

The aim of this study is to investigate the public opinion (i.e., the learners themselves) of apps incorporating emerging technologies Augmented Reality (AR) and Virtual Reality (VR) and find out how satisfied mobile platform users are with these technologies for educational purposes. We performed sentiment analysis of more than one million reviews from 800 different Android apps collected by systematic scrapping of the Google Play Store. Identified apps were separated into five categories: AR, AR+Educational, VR, VR+Educational, and Educational. We identify reviews from each app as positive, negative, or neutral, and apply aspect labels depending on the content of the review. We adopted Bidirectional Encoder Representations from Transformers (BERT) and classify the labels into seven categories: technical issues, usability, content, user interaction, feature request, learning qualities, and advert-related. The results indicate that the positive sentiments are 54.6% for AR, 49.6% for AR+Educational, 47.7% for VR, 71.4% for VR+Educational, and 75.2% for Educational. The results suggest that education apps that do not incorporate AR or VR are receiving higher user satisfaction than apps that incorporate these emerging technologies. Analyzing and understanding user reviews will help instructional designers, software developers, and hardware designers to resolve the key inhibitors.of these apps. [ABSTRACT FROM AUTHOR]
