The popularity of mixed reality (MR) technologies, including virtual (VR) and augmented (AR) reality, have advanced many training and skill development applications. If successful, these technologies could be valuable for high-impact professional training, like medical operations or sports, where the physical resources could be limited or inaccessible. Despite MR's potential, it is still unclear whether repeatedly performing a task in MR would affect performance in the same or related tasks in the physical environment. To investigate this issue, participants executed a series of visually-guided manual pointing movements in the physical world before and after spending one hour in VR or AR performing similar movements. Results showed that, due to the MR headsets' intrinsic perceptual geometry, movements executed in VR were shorter and movements executed in AR were longer than the veridical Euclidean distance. Crucially, the sensorimotor bias in MR conditions also manifested in the subsequent post-test pointing task; participants transferring from VR initially undershoot whereas those from AR overshoot the target in the physical environment. These findings call for careful consideration of MR-based training because the exposure to MR may perturb the sensorimotor processes in the physical environment and negatively impact performance accuracy and transfer of training from MR to UR.

Simple Summary: As breast cancer rates rise, more patients choose breast reconstruction. Autologous breast reconstruction (ABR) may be more cost-effective and offer superior patient quality of life compared to prosthetic implant-based reconstruction but it involves heightened surgical complexity and extended operative time. Imaging facilitates surgical planning, patient selection, and reduces the time spent in the operating room, thereby enhancing the likelihood of surgical success and decreasing complication rates. Advanced imaging has also spurred innovative surgical techniques aimed at improving aesthetic outcomes and minimizing donor-site morbidity, including robotic-assisted deep inferior epigastric flap perforator (DIEP) flap harvest and stacked microsurgical flaps. The evolution of imaging actively shapes clinical management in the field. Ultrasonography (US), computed tomography angiography (CTA), and magnetic resonance angiography (MRA) stand out as the most extensively researched imaging modalities for ABR. Ongoing advancements include "real-time" angiography and three-dimensional (3D) surface imaging, and future prospects incorporate augmented or virtual reality (AR/VR) and artificial intelligence (AI). These technologies may further enhance perioperative efficiency, reduce donor-site morbidity, and improve surgical outcomes in ABR. [ABSTRACT FROM AUTHOR]

Assembly simulation and evaluation have become an effective means to analyze product assembly design and assembly plan. Compared with the widely used digital assembly simulation method, the AR-based human-in-the-loop assembly simulation and evaluation method can discover and solve the problems related to the human factors, which is very important for manual assembly. This paper proposes an AR-based human-in-the-loop manual assembly evaluation with high-fidelity assembly simulation method. By proposing the natural human assembly gesture intention recognition method and the virtual assembling parts motion simulation method based on the dual geometric and physical constraints, the AR-based human-in-the-loop manual assembly simulation is realized to provided natural assembly simulation experience and generate realistic assembly simulation process data. In addition, the assembly evaluation methods are integrated to objectively evaluate the performance and operation difficulty of manual assembly process, which comprehensively capture and utilize the human-in-the-loop assembly simulation data including the assembly hand actions, assembly visibility, and assembly time. Finally, the prototype system was developed based on the proposed method and verified in an assembly case by a set of experiments. The results illustrate that the assembly simulation is high fidelity and the assembly evaluation more comprehensively by using the proposed method, realizing a high consistence between virtual and real assembly process validation. This study provides a practical methodology for the manual assembly simulation and evaluation through human-in-the-loop in the AR environment. [ABSTRACT FROM AUTHOR]

With the introduction of the metaverse, augmented reality (AR) is expected to become the next interface between people and computers. Research is conducted to improve the usability of AR applications and devices. Color transparency and background effect are the two critical factors to consider while developing AR applications. Ten user interface conditions (5 color transparency levels × 2 background conditions) were evaluated in an AR environment. The task completion time and mean error were noted along with the subjective scores of button visibility, background visibility, and motion sickness. The results revealed a significant difference in task completion time, button visibility, and background visibility between transparency conditions, but not in the number of errors and total motion sickness. The transparency level of T0.5 and T0.75 is recommended for the interface of AR applications. This study could be helpful when creating augmented reality applications for the metaverse and other platforms. [ABSTRACT FROM AUTHOR]

Building on several decades of research and development, the recent progress in virtual reality (VR) and augmented reality (AR) devices with spatial computing technologies marks a significant leap in human–computer interaction, with applications ranging from entertainment and education to e‐commerce and healthcare. Advances in these technologies promise immersive experiences by simulating and augmenting the real world with computer‐generated digital content. The core objective of the VR and AR systems is to create convincing human sensory perceptions, thereby creating immersive and interactive experiences that bridge the gap between virtual and physical realities. However, achieving true immersion remains a goal, and it necessitates a comprehensive understanding of the neuroscience of human multisensory perception and accurate technical implementations to create a consistency between natural and synthetic sensory cues. This paper reviews the human sensory‐perceptual requirements vital for achieving such immersion, examines the current status and challenges, and discusses potential future advancements.

A head‐up display (HUD) is conveniently used to provide information on the display without changing the user's gaze. 3D HUDs, capable of projecting three‐dimensional information beyond the 2D HUDs, enable the projection of augmented reality (AR) objects into the real world. Research on the perception of 3D AR HUDs is crucial for their efficient utilization and secure commercialization. In this study, we examined whether a 3D HUD is more comfortable than a 2D HUD in the context of viewing real‐world environments and augmented reality objects together. Additionally, we analyzed participants' perception of distance and fatigue for AR objects at varying distances from the 3D HUD. The study found that using a 3D HUD in an AR environment resulted in less fatigue than using a 2D HUD, as determined by a Mann–Whitney statistical analysis. Participants were able to match the depth of AR objects in a 3D HUD within a range of 3 to 50 m, with similar diopter and parallax angular distance errors, regardless of the distance of the AR object. Visual fatigue increases with increasing distance from the virtual‐image plane and can be modeled as a quadratic function in the domain of diopter and parallax angles. [ABSTRACT FROM AUTHOR]

Geometry is considered a fundamental component to be mastered in the elementary school mathematics curriculum. Lower primary school pupils frequently experience obstacles because of the abstract nature of geometric concepts and the requirement for spatial visualization skills, which are necessary for strengthening their conceptual understanding. Augmented reality (AR) technology offers a promising solution by providing visual representations of geometric shapes. Thus, this study aimed to investigate the effects of AR technology in primary school education on pupils’ spatial visualization abilities in geometry. Employing a quasiexperimental pre- and post-test research design, this study involved 61 second-grade pupils from two Northern Malaysian primary schools. The selection of schools followed cluster sampling techniques, while intact groups were utilized to select samples. Data were collected from two groups: an experimental group that utilized the LearnGeoAR applications and a control group that employed conventional teaching methods to learn geometric shapes. This study used the spatial visualization ability test (SVAT) instrument, grounded in Van Hiele’s theory of geometric thinking. The findings revealed that the experimental group, which utilized AR applications, exhibited a higher mean score in pupils’ spatial visualization ability in geometry compared to the control group. Additionally, the experiment demonstrated a moderate effect on both groups. This finding highlights the potential of AR technology in enhancing pupils’ spatial visualization skills in geometry instruction, providing valuable insights for instructional methodologies.

Achieving optimal patient safety (PS) remains a challenge in healthcare. Effective educational methods are critical for improving PS. Innovative teaching tools, like case-based learning, augmented reality, and active learning, can help students better understand and apply PS and healthcare quality improvement (HQI) principles. This study aimed to assess activities and tools implemented to improve PS and HQI education, as well as student engagement, in medical schools. We designed a two-week course for fourth-year medical students at the Autonomous University of Guadalajara, incorporating Fink's taxonomy of significant learning to create engaging activities. The course featured daily synchronous and asynchronous learning, with reinforcement activities using tools, like augmented reality and artificial intelligence. A total of 394 students participated, with their performance in activities and final exam outcomes analyzed using non-parametric tests. Students who passed the final exam scored higher in activities focused on application and reasoning (p = 0.02 and p = 0.018, respectively). Activity 7B, involving problem-solving and decision-making, was perceived as the most impactful. Activity 8A, a case-based learning exercise on incident reporting, received the highest score for perception of exam preparation. This study demonstrates innovative teaching methods and technology to enhance student understanding of PS and HQI, contributing to improved care quality and patient safety. Further research on the long-term impact is needed. [ABSTRACT FROM AUTHOR]

Deep learning is a very popular topic in computer sciences courses despite the fact that it is often challenging for beginners to take their first step due to the complexity of understanding and applying Artificial Neural Networks (ANN). Thus, the need to both understand and use neural networks is appearing at an ever-increasing rate across all computer science courses. Our objectives in this project were to create a framework for creating and training neural networks for solving different problems real-life problems and for research and education, as well as to investigate the usability of our framework. To provide an easy to use framework, this research recruited five instructors who have taught ANNs at two universities. We asked thirty-one students who have previously studied neural networks to fill out an online survey about what were "the major difficulties in learning NNs" and the "key requirements in a Visual Learning Tool including the most desired features of a visualization tool for explaining NNs" they would have used during the course. We also conducted an observational study to investigate how our students would use this system to learn about ANNs. The visual presentation of ANNs created in our framework can be represented in an Augmented Reality (AR) and Virtual Reality (VR) environment thus allowing us to use a virtual space to display and manage networks. An evaluation of the effect of the AR/VR experience through a formative test and survey showed that the majority of students had a positive response to the engaging and interactive features of our framework (RKNet).

Augmented reality (AR) technology has opened up new possibilities for interactive and immersive learning experiences, where students can visualize abstract concepts and engage with digital objects in real-time. In this study, a real-time AR-based system is developed and, unlike other studies, incorporates sound effects that will play when the object is detected to support the teaching of English words to primary school students. Using the You Look Only Once (YOLO) v4 algorithm and the Common Objects in Context (COCO) dataset, the system was trained to detect objects with high accuracy. The proposed system was tested on 40 primary school students for 8 weeks and compared their learning outcomes with a control group using traditional teaching methods. According to the experimental results, students utilizing the AR-based system achieved an impressive 90% success rate in the end-of-term exam, whereas the control group attained a success rate of 65%. Our study demonstrates the potential of AR technology to enhance children's motivation and engagement in learning the English language. [ABSTRACT FROM AUTHOR]

AR technology is utilized in several disciplines at various educational levels, from primary to higher education. It is evident that AR technology has been investigated by addressing numerous subtopics related to individuals at different levels of science and mathematics education within the field of special education. Since emerging evidence indicates that the implementation of this technology has a positive impact on students' acquisition of academic skills, it could be argued that more effort is required to develop and implement AR applications for students with cognitive challenges. This study aims to identify the areas of science and mathematics where secondary school students with SEN encounter learning difficulties by conducting a needs analysis with special education professionals. The purposive sampling method was employed for this study, and a total of 150 teachers were interviewed. The findings indicate that science teachers struggle to teach students with learning disabilities, particularly in subjects requiring abstract thinking and physics. In addition to science classes, teachers stated that they encountered difficulties when teaching certain mathematics subjects, such as the four operations, fraction problem-solving, and geometric shapes, to students with learning difficulties. Finally, teachers also suggested that augmented reality applications should be implemented for mathematics topics like problem-solving, fractions, geometry, ratio, and proportion.

The purpose of this study was to investigate the effects of Augmented Reality (AR) technology on vocabulary development and attitudes toward AR in pre-school English instruction. The study, which was grounded on a pretest–posttest control group quasi-experimental design, included 36 pre-school children aged from 4 to 5. While the participants in the control group used flashcards, matching cards, and puzzles to learn English equivalents of target vocabulary, the participants in the experimental group used the same materials presented through AR applications, enabling them to see 3D animated models and listen to English pronunciation. The results revealed significant differences between groups in terms of vocabulary learning, attitude, and enjoyment levels, with the experimental group performing better. Although there was no statistically significant difference in terms of emotions between the groups, the participants in the experimental group developed more positive feelings towards AR-supported activities than those in the control group. In addition, some participants with lower emotional levels in the control group had undecided and unhappy emotional states. As a result, it can be said that AR technology contributed to language learning in pre-school English classes and that this technology positively influenced the participants' attitudes and enjoyment.

Museums have expanded beyond their initial role in preserving artefacts as memory intuitions, playing an educational role and being tourist attractions. They had to adapt and increasingly utilise digital technologies to stay relevant in contemporary times. The use of technology in museums can be divided into two domains: digitalisation and digitisation. This study reviews 83 screened articles aligning with the guidelines of PRISMA systematic review to analyse existing knowledge about digitalisation and digitisation in museums, to demonstrate how these processes impact the role of museums, memory-making, and identify gaps for further research. The results indicate that digitalisation and digitisation enhance the overall museum experience for museum visitors and promote the educational aspect of museums as an 'interconnected space'. Notable use of digitalisation includes the use of Virtual Reality and Augmented Reality, while digitisation often is present through museum websites. Nonetheless, four current challenges for museums have been identified that warrant further research. [ABSTRACT FROM AUTHOR]

Tourism is an excellent pathway with which to promote and provide access to cultural heritage. Sustainable cultural tourism offers a new perspective, as it places cultural heritage and local communities at the centre of decision-making processes. In this context, traditional tourism must be updated accordingly to the new times. This research aims to classify a cultural heritage piece found in the ruins of what used to be the Castle of Montilla, and produce a 3D virtual model using innovative technologies, to be appreciated in the metaverse, as a virtual museum. The idea of tourism as a real movement of people should be shifted little by little to an idea of connection without the need of being there exactly. This research succeeded with this idea. A 'perfume burner', catalogued as a lamp, and currently located in the medieval section of the Local Historical Museum of Montilla (Cordoba, Spain), was virtually reconstructed. In the attainment of these physical subjects transferred to the metaverse, photogrammetry played a crucial role. Obtaining a 3D digital model of a heritage asset enables the public in general, present and non-present visitors, to appreciate such cultural pieces. In this context, tourist agents and resources might be changed and updated to bring tourist services and clients. The metaverse is paramount in creating virtual museums, providing the possibility of establishing connections with people without the need to be physically in a certain place. The virtual museum leverages digital technology to promote sustainability by reducing travels and minimising the environmental impact. To date, this research enhances the experiences of the users at the local museum. [ABSTRACT FROM AUTHOR]

The issue of brightness in strong ambient light conditions is one of the critical obstacles restricting the application of augmented reality (AR) and mixed reality (MR). Gallium nitride (GaN)-based micro-LEDs, renowned for their exceptional brightness and stability, are considered the foremost contenders for AR applications. Nevertheless, conventional heteroepitaxial growth micro-LED devices confront formidable challenges, including substantial wavelength shifts and efficiency droop. In this paper, we firstly demonstrated the high-quality homoepitaxial GaN-on-GaN micro-LEDs micro-display, and thoroughly analyzed the possible benefits for free-standing GaN substrate from the material-level characterization to device optoelectronic properties and micro-display application compared with sapphire substrate. The GaN-on-GaN structure exhibits a superior crystal quality with ultra-low threading dislocation densities (TDDs) of ~ 105 cm−2, which is three orders of magnitude lower than that of GaN-on-Sapphire. Through an in-depth size-dependent optoelectronic analysis of blue/green emission GaN-on-GaN/ Sapphire micro-LEDs from 100 × 100 shrink to 3 × 3 μm2, real that a lower forward voltage and series resistance, a consistent emission wavelength (1.21 nm for blue and 4.79 nm for green @ 500 A/cm2), coupled with a notable reduction in efficiency droop ratios (15.6% for blue and 28.5% for green @ 500 A/cm2) and expanded color gamut (103.57% over Rec. 2020) within GaN-on-GaN 10 μm micro-LEDs. Last but not least, the GaN-on-GaN micro-display with 3000 pixels per inch (PPI) showcased enhanced display uniformity and higher luminance in comparison to its GaN-on-Sapphire counterpart, demonstrating significant potentials for high-brightness AR/MR applications under strong ambient light.

Gesture recognition is crucial in computer vision-based applications, such as drone control, gaming, virtual and augmented reality (VR/AR), and security, especially in human–computer interaction (HCI)-based systems. There are two types of gesture recognition systems, i.e., static and dynamic. However, our focus in this paper is on dynamic gesture recognition. In dynamic hand gesture recognition systems, the sequences of frames, i.e., temporal data, pose significant processing challenges and reduce efficiency compared to static gestures. These data become multi-dimensional compared to static images because spatial and temporal data are being processed, which demands complex deep learning (DL) models with increased computational costs. This article presents a novel triple-layer algorithm that efficiently reduces the 3D feature map into 1D row vectors and enhances the overall performance. First, we process the individual images in a given sequence using the MediaPipe framework and extract the regions of interest (ROI). The processed cropped image is then passed to the Inception-v3 for the 2D feature extractor. Finally, a long short-term memory (LSTM) network is used as a temporal feature extractor and classifier. Our proposed method achieves an average accuracy of more than 89.7%. The experimental results also show that the proposed framework outperforms existing state-of-the-art methods.

Introduction: Augmented reality (AR) has been increasingly studied in transportation, particularly for drivers and pedestrians interacting with automated vehicles (AVs). Previous research evaluated AR interfaces using online video-based questionnaires but lacked human-subject research in immersive environments. This study examined if prior online evaluations of nine AR interfaces could be replicated in an immersive virtual environment and if AR interface effectiveness depends on pedestrian attention allocation. Methods: Thirty participants completed 120 trials in a CAVE-based simulator with yielding and non-yielding AVs, rating the interface's intuitiveness and crossing the road when they felt safe. To emulate visual distraction, participants had to look into an attention-attractor circle that disappeared 1 s after the interface appeared. Results: The results showed that intuitiveness ratings from the current CAVEbased study and the previous online study correlated strongly (r = 0.90). Headlocked interfaces and familiar designs (augmented traffic lights, zebra crossing) yielded higher intuitiveness ratings and quicker crossing initiations than vehiclelocked interfaces. Vehicle-locked interfaces were less effective when the attention-attractor was on the environment's opposite side, while headlocked interfaces were relatively unaffected by attention-attractor position. Discussion: In conclusion, this 'AR in VR' study shows strong congruence between intuitiveness ratings in a CAVE-based study and online research, and demonstrates the importance of interface placement in relation to user gaze direction.

In the contemporary era of urban design, the advent of big data and digital technologies has ushered in innovative approaches to exploring urban spaces. This study focuses on the application of Augmented Reality (AR) and Extended Reality (XR) technologies in the metropolitan areas of Houston and Amsterdam. These technologies create immersive 'Phygital Installations' that blend physical and digital elements, effectively capturing people's perceptions and enhancing urban design proposals. By fostering human-centered planning, AR and XR technologies make urban design more interactive and accessible to the public. Houston, with its rapid industrial growth and diverse socio-economic landscape, provides a unique setting to examine the impacts of these technologies on urban form and socio-environmental dynamics. In contrast, Amsterdam, with its rich historical layers and socio-cultural diversity, offers insights into the integration of AR/XR technologies in urban planning, particularly in the realm of historical preservation and contemporary urban development. This research contributes to the emerging field of AR/XR in urban design by highlighting the transformative potential of these technologies in enhancing the understanding and engagement in urban design and spatial planning.

This paper addresses the problem of 6D pose tracking of plane segments from point clouds acquired from a mobile camera. This is motivated by manual packing operations, where an opportunity exists to enhance performance, aiding operators with instructions based on augmented reality. The approach uses as input point clouds, by its advantages for extracting geometric information relevant to estimating the 6D pose of rigid objects. The proposed algorithm begins with a RANSAC fitting stage on the raw point cloud. It then implements strategies to compute the 2D size and 6D pose of plane segments from geometric analysis of the fitted point cloud. Redundant detections are combined using a new quality factor that predicts point cloud mapping density and allows the selection of the most accurate detection. The algorithm is designed for dynamic scenes, employing a novel particle concept in the point cloud space to track detections' validity over time. A variant of the algorithm uses box size priors (available in most packing operations) to filter out irrelevant detections. The impact of this prior knowledge is evaluated through an experimental design that compares the performance of a plane segment tracking system, considering variations in the tracking algorithm and camera speed (onboard the packing operator). The tracking algorithm varies at two levels: algorithm ( A wpk ), which integrates prior knowledge of box sizes, and algorithm ( A woutpk ), which assumes ignorance of box properties. Camera speed is evaluated at low and high speeds. Results indicate increments in the precision and F1-score associated with using the A wpk algorithm and consistent performance across both velocities. These results confirm the enhancement of the performance of a tracking system in a real-life and complex scenario by including previous knowledge of the elements in the scene. The proposed algorithm is limited to tracking plane segments of boxes fully supported on surfaces parallel to the ground plane and not stacked. Future works are proposed to include strategies to resolve this limitation. [ABSTRACT FROM AUTHOR]

We present a new rehabilitation system based on novel principles, which consists of an auditory augmented reality (AR) headset we originated. The auditory AR headset, which does not cover both ears, allows users to hear both Real and Virtual environmental sounds at the same time. It can also be used in combination with Hearing Aids. We have studied a system to support hearingimpaired people and conducted a test evaluation. The system was able to provide convenience akin to “reading glasses for sound” to those who had mild hearing disabilities. Furthermore, by combining the system with surrounding speakers, a completely novel virtual auditory illusion was created in which the sound image jumps into the ear and runs away. We name this “proximal auditory AR (PAAR)” system. This system directly affects the unconscious level of reflexes for maintaining a standing position and can generate very subtle body motion disturbance. Using this system, we can modulate the standing posture and observe the autonomic nerve system’s ability to subliminally compensate for the disturbance, using a stabilometer that measures body sways by center of pressure (COP). We observed a significant difference in the declination of COP only when using the PAAR, which is combined with array speakers and the auditory AR headphone, compared using a conventional closed-type and a bone-conduction headphone. By analyzing such big data of physical movement through machine learning, we expect to realize new systems for diagnosis, rehabilitation, function maintenance, and fall prevention.

Chemistry as a whole is divided into three levels. The macroscopic level describes real, observable phenomena of the material world. The submicroscopic level focuses on particles. The representative level includes pictorial and symbolic representations to visualize substance in its nature. Students often have problems separating these levels and conceptually transfer each of the three levels to the other. Therefore, teachers need to use chemical terminology correctly when teaching the substance-particle concept. Augmented Reality (AR) connects real and virtual world. The observer physically moves in a real environment that integrates virtual elements. The AR technology has great potential for learning in the subject chemistry, especially when it comes to making the "invisible" visible and illustrating scientific phenomena at particle level. The simultaneous presentation should avoid split-attention and offers new possibilities to interactively deal with (M)ER. The question arises whether AR has a positive effect on the use of technical language and the associated understanding of the concept of dealing with (M)ER at the substance and particle levels. With an AR app on the tablet and the AR glasses, the chemical processes of a real experiment are represented by AR visualizations. Therefore, the AR app was piloted. This study captured the chemistry handling with (M)ER of chemistry teachers (N = 30) using a pre-post survey. The participating preservice teachers are described below. Each test includes five tasks elaborated by thinking aloud. The thinking-aloud protocols to acquire the use of the chemical terminology are evaluated in MAXQDA. [ABSTRACT FROM AUTHOR]

Engineering drawing is valuable in capturing geometric features, conveying engineering ideas, and creating a blueprint of the intended product. Engineering students usually perform orthographic projections, imagining a 3D situation and sketching its 2D representation. That requires imagination and mental visualization, determined by the learner's spatial ability. This study proposes the infusion of an AR stereogram mobile application into an engineering drawing course to establish how it influences learning outcomes among students with different spatial abilities. The quantitative experimental study involved two mechanical engineering classes in northern Taiwan, N = 69 first-year vocational high schoolers. Statistical analysis revealed that the experimental group with high spatial ability recorded better results and excellent drawing skills. Bloom's taxonomy categorization reported that spatial ability influenced "understanding" and "applying" levels, with the strongest effect on "understanding." Although no significant interaction existed, learning outcomes were highly affected by spatial ability in "understanding" and "applying" levels and AR in the overall performance. The findings and discussions show AR holds great potential to enhance students' spatial ability for real-time visualization and enables better concept comprehension by improving their understanding of engineering topics. Future studies should consider these implications in creating effective and immersive learning environments for different courses in engineering education. [ABSTRACT FROM AUTHOR]

This study investigates the use of virtual and augmented reality (VAR) in higher education on students' self-efficacy in science and engineering, and academic performance. An innovative VAR classroom is set up as an immersive and interactive learning environment at Nanyang Technological University for curriculum-based learning. This classroom is equipped with 6 individual VR displays and headsets, where high-end computers are connected to each display providing the computational power required for VAR technology. 46 undergraduate engineering students experience the VAR lessons over the course of 5 weeks. The self-efficacy and academic performance of the students are measured for quantitative analysis with surveys and regular (pre-/post-) tests as they participated in the lessons. Post-lesson focus-group discussions and interviews are conducted for qualitative analysis. The data analysis shows a significant increase in students' self-efficacy levels and academic performance after 5 weeks of VAR lessons. It is found that the collaborative, interactive and immersive nature of the VAR learning environment enriches students' learning experiences and thus contributes to their learning effectiveness. The study provides insights into how the VAR learning environment affects undergraduate students' learning, and how the VAR system can be deployed for effective STEM education [ABSTRACT FROM AUTHOR]

In the global context, advancements in technology and science have rendered virtual, augmented, and mixed-reality technologies capable of transforming clinical care and medical environments by offering enhanced features and improved healthcare services. This paper aims to present a mixed reality-based system to control a robotic wheelchair for people with limited mobility. The test group comprised 11 healthy subjects (six male, five female, mean age 35.2 ± 11.7 years). A novel platform that integrates a smart wheelchair and an eye-tracking-enabled head-mounted display was proposed to reduce the cognitive requirements needed for wheelchair movement and control. The approach's effectiveness was demonstrated by evaluating our system in realistic scenarios. The demonstration of the proposed AR head-mounted display user interface for controlling a smart wheelchair and the results provided in this paper could highlight the potential of the HoloLens 2-based innovative solutions and bring focus to emerging research topics, such as remote control, cognitive rehabilitation, the implementation of patient autonomy with severe disabilities, and telemedicine.

The advent and progression of AR (augmented reality) technology, coupled with the emergence of AR hearing aid glasses, offer a novel opportunity for people with hearing impairments (PHI). This study aims to explore the intention of this population to employ AR hearing aid glasses as their choice of hearing aid device and the specific factors influencing their preference. This study utilized the partial least squares SEM (PLS-SEM) analytical method to create structural equation model for intentions of PHI to use AR glasses as hearing aids. Data were gathered from on-site experiences across multiple locations; a total of 189 valid questionnaires from individuals with varying degrees of hearing disabilities were used for statistical analysis. According to the data analysis results, we discovered that functionality quality, perceived interaction speed, and perceived usability significantly influence communication effectiveness. Further, communication effectiveness positively influences confidence and societal perception, and the latter has a positive impact on information. Both of these factors positively influence behavioral intention. Based on these findings, this study offers design recommendations for AR hearing aid glasses to cater to the specific needs of PHI, aiming to enhance their quality of life. Furthermore, this study provides pivotal insights for the prospective growth of this emerging industry. [ABSTRACT FROM AUTHOR]

Background: To date, the benefit of image guidance during robot-assisted surgery (IGS) is an object of debate. The current study aims to address the quality of the contemporary body of literature concerning IGS in robotic surgery throughout different surgical specialties. Methods: A systematic review of all English-language articles on IGS, from January 2013 to March 2023, was conducted using PubMed, Cochrane library's Central, EMBASE, MEDLINE, and Scopus databases. Comparative studies that tested performance of IGS vs control were included for the quantitative synthesis, which addressed outcomes analyzed in at least three studies: operative time, length of stay, blood loss, surgical margins, complications, number of nodal retrievals, metastatic nodes, ischemia time, and renal function loss. Bias-corrected ratio of means (ROM) and bias-corrected odds ratio (OR) compared continuous and dichotomous variables, respectively. Subgroup analyses according to guidance type (i.e., 3D virtual reality vs ultrasound vs near-infrared fluoresce) were performed. Results: Twenty-nine studies, based on 11 surgical procedures of three specialties (general surgery, gynecology, urology), were included in the quantitative synthesis. IGS was associated with 12% reduction in length of stay (ROM 0.88; p = 0.03) and 13% reduction in blood loss (ROM 0.87; p = 0.03) but did not affect operative time (ROM 1.00; p = 0.9), or complications (OR 0.93; p = 0.4). IGS was associated with an estimated 44% increase in mean number of removed nodes (ROM 1.44; p < 0.001), and a significantly higher rate of metastatic nodal disease (OR 1.82; p < 0.001), as well as a significantly lower rate of positive surgical margins (OR 0.62; p < 0.001). In nephron sparing surgery, IGS significantly decreased renal function loss (ROM 0.37; p = 0.002). Conclusions: Robot-assisted surgery benefits from image guidance, especially in terms of pathologic outcomes, namely higher detection of metastatic nodes and lower surgical margins. Moreover, IGS enhances renal function preservation and lowers surgical blood loss. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this systematic review is to assess the clinical implications of employing various Extended Reality (XR) tools for image guidance in urological surgery. Methods: In June 2023, a systematic electronic literature search was conducted using the Medline database (via PubMed), Embase (via Ovid), Scopus, and Web of Science. The search strategy was designed based on the PICO (Patients, Intervention, Comparison, Outcome) criteria. Study protocol was registered on PROSPERO (registry number CRD42023449025). We incorporated retrospective and prospective comparative studies, along with single-arm studies, which provided information on the use of XR, Mixed Reality (MR), Augmented Reality (AR), and Virtual Reality (VR) in urological surgical procedures. Studies that were not written in English, non-original investigations, and those involving experimental research on animals or cadavers were excluded from our analysis. The quality assessment of comparative and cohort studies was conducted utilizing the Newcastle-Ottawa scale, whilst for randomized controlled trials (RCTs), the Jadad scale was adopted. The level of evidence for each study was determined based on the guidelines provided by the Oxford Centre for Evidence-Based Medicine. Results: The initial electronic search yielded 1,803 papers after removing duplicates. Among these, 58 publications underwent a comprehensive review, leading to the inclusion of 40 studies that met the specified criteria for analysis. 11, 20 and 9 studies tested XR on prostate cancer, kidney cancer and miscellaneous, including bladder cancer and lithiasis surgeries, respectively. Focusing on the different technologies 20, 15 and 5 explored the potential of VR, AR and MR. The majority of the included studies (i.e., 22) were prospective non-randomized, whilst 7 and 11 were RCT and retrospective studies respectively. The included studies that revealed how these new tools can be useful both in preoperative and intraoperative setting for a tailored surgical approach. Conclusions: AR, VR and MR techniques have emerged as highly effective new tools for image-guided surgery, especially for urologic oncology. Nevertheless, the complete clinical advantages of these innovations are still in the process of evaluation. [ABSTRACT FROM AUTHOR]

Spatial computing – that is, a form of human–computer interaction that retains or manipulates referents of real object and spaces – is an increasingly intense focus for Meta. In 2018, Meta launched 'Reality Labs' (RL), a research and development division to oversee the company's production of spatial computing technologies. Drawing on a media historiographical approach from platform studies, this article charts the development of the company's spatial computing ambitions through RL from 2018 to 2022. In so doing, we find that Meta attempts to consolidate complementors through acquisitions, capture policymakers and academics, convene third-party businesses and developers, and expand its ecosystem through enhancing platform programmability. We argue that RL's efforts to grow the platform from within, and through drawing in third-parties, signals an ambition to grow their spatial computing offerings such that they take on a central, infrastructural role in society.

This study introduces an innovative surgical approach for total knee arthroplasty (TKA) that combines kinematic alignment (KA) principles with real-time elongation of the knee ligaments through the range of motion, using augmented reality (AR). The novelty of the surgical technique lies in the possibility of enhancing the decision-making process to perform the cut on the tibia as for the KA caliper technique developed by Dr. Stephen Howell. The NextAR is a CT-based AR system that offers the possibility of performing three-dimensional surgical preoperative planning and an accurate execution in the surgical room through single-use infrared sensors, smart glasses, and a control unit. During the preoperative planning, the soft tissue is not considered and only the alignment based on bony reference is ensured. Thanks to the possibility of measuring in real time the elongation of the knee collateral lateral ligaments, the system assists the surgeon in optimizing the cut on the tibia after an accurate resurfacing of the femur as described in the KA surgical technique. The implant used in this novel approach is a medial pivot design (Medacta GMK Sphere) that allows the restoration of the physiological behavior of the software tissue and natural knee kinematics. In conclusion, this novel technique offers a promising approach to TKA, allowing personalized treatment tailored to each patient's unique anatomy and soft tissue characteristics. The integration of KA and real-time soft tissue analysis provided by NextAR enhances surgical precision and outcomes, potentially improving patient satisfaction and functional results.

Purpose: To compare two cohorts of patients submitted to robot-assisted partial nephrectomy (RAPN) for highly-complex renal masses (PADUA ⩾ 10) with versus without the use of 3DVMs. Materials and Methods: We screened a prospective consecutive cohort of 152 patients submitted to RAPN with 3DVM and 1264 patients submitted to RAPN without 3DVM between 2019 and 2022. Only PADUA ⩾ 10 cases were considered eligible for analysis. Propensity score matching (PSM) analysis was applied. Primary endpoint was to evaluate whereas RAPNs with 3DVM were superior in terms of functional outcomes at 12-month. Secondary outcomes were to compare perioperative and oncological outcomes. Multivariable logistic regression analyses (MVA) tested the associations of clinically significant eGFR drop and 3DVMs. Subgroups analysis was performed for PAUDA-risk categories. Results: Thirty seven patients for each group were analyzed after PSM. RAPN with 3DVM presented a higher rate of selective/no clamping procedure (32.5% vs 16.2%, p = 0.03) and a higher enucleation rate (43.2% vs 29.8%, p = 0.04). Twelve-month functional preservation performed better within 3DVM group in terms of creatinine serum level (median 1.2 [IQR 1.1–1.4] vs 1.6 [IQR 1.1–1.8], p = 0.03) and eGFR (median 64.6 [IQR 56.2–74.1] vs 52.3 [IQR 49.2–74.1], p = 0.03). MVA confirmed 3DVM as a protective factor for clinically significant eGFR drop in this subgroup of patients. Conclusions: RAPN performed with the use of 3DVM assistance for PADUA ⩾ 10 cases resulted in lower incidence of global ischemia and higher rate of enucleations. The positive impact of such technology was found at 12-month follow-up. [ABSTRACT FROM AUTHOR]

Focusing on three ludic journeys through an autoethnographic account of Wellington, New Zealand, this paper explores how the performance of playful movements can alter the meaning, practice, and feeling of urban spaces. Attention is drawn to becoming hybrid, how technology mediates and augments the power to transform the everyday and support playful engagement with the city. These three ludic stories focus on e-scootering, cycling, and playing an augmented reality game, and highlight how play orientates our bodies through a sense of 'with-ness', with our environment and others. It also looks at orientations of 'against-ness', a leaning away from the materiality of objects, spaces, and events through play. This paper concludes by drawing on how space feels, and how it may open up the design potentials that these mediated practices offer. [ABSTRACT FROM AUTHOR]

Surgical education demands extensive knowledge and skill acquisition within limited time frames, often limited by reduced training opportunities and high-pressure environments. This review evaluates the effectiveness of extended reality-based head-mounted display (ExR-HMD) technology in surgical education, examining its impact on educational outcomes and exploring its strengths and limitations. Data from PubMed, Cochrane Library, Web of Science, ScienceDirect, Scopus, ACM Digital Library, IEEE Xplore, WorldCat, and Google Scholar (Year: 2014–2024) were synthesized. After screening, 32 studies comparing ExR-HMD and traditional surgical training methods for medical students or residents were identified. Quality and bias were assessed using the Medical Education Research Study Quality Instrument, Newcastle–Ottawa Scale-Education, and Cochrane Risk of Bias Tools. Results indicate that ExR-HMD offers benefits such as increased immersion, spatial awareness, and interaction and supports motor skill acquisition theory and constructivist educational theories. However, challenges such as system fidelity, operational inconvenience, and physical discomfort were noted. Nearly half the studies reported outcomes comparable or superior to traditional methods, emphasizing the importance of social interaction. Limitations include study heterogeneity and English-only publications. ExR-HMD shows promise but needs educational theory integration and social interaction. Future research should address technical and economic barriers to global accessibility. [ABSTRACT FROM AUTHOR]

This article explores the use of arts-led approaches to augmented reality (AR) marker design through the presentation of four commissioned projects featuring AR markers created using traditional techniques including drawing, hand weaving, and tiling. The physical-to-digital process to convert artworks into AR markers produces opportunities for cocreation with diverse participants and for materiality to shape the AR experience. Reflecting on the materiality of the different techniques in relation to the temporal, spatial, and social settings of each project (arts festivals, a summer school, and workshops on heat wave-risk communication), the authors argue for a responsive approach to integrating multimodal dynamic markers.

Objective The aim of this work was the development of an augmented reality system including the functionality of conventional surgical navigation systems. Methods An application software for the Augmented Reality System HoloLens 2 from Microsoft was developed. It detects the position of the patient as well as position of surgical instruments in real time and displays it within the two-dimensional (2D) magnetic resonance imaging or computed tomography (CT) images. The surgical pointer instrument, including a pattern that is recognized by the HoloLens 2 sensors, was created with three-dimensional (3D) printing. The technical concept was demonstrated at a cadaver skull to identify anatomical landmarks. Results With the help of the HoloLens 2 and its sensors, the real-time position of the surgical pointer instrument could be shown. The position of the 3D-printed pointer with colored pattern could be recognized within 2D-CT images when stationary and in motion at a cadaver skull. Feasibility could be demonstrated for the clinical application of transsphenoidal pituitary surgery. Conclusion The HoloLens 2 has a high potential for use as a surgical navigation system. With subsequent studies, a further accuracy evaluation will be performed receiving valid data for comparison with conventional surgical navigation systems. In addition to transsphenoidal pituitary surgery, it could be also applied for other surgical disciplines. [ABSTRACT FROM AUTHOR]

In the expanding fields of mobile technology and augmented reality, there is a growing demand for compact, high‐fidelity spectral imaging systems. Traditional spectral imaging techniques face limitations due to their size and complexity. Diffractive optical elements (DOEs), although helpful in reducing size, primarily modulate the phase of light. Here, an end‐to‐end computational spectral imaging framework based on polarization‐multiplexed metalens is introduced. A distinguishing feature of this approach lies in its capacity to simultaneously modulate orthogonal polarization channels. When harnessed in conjunction with a neural network, it facilitates the attainment of high‐fidelity spectral reconstruction. Importantly, the framework is intrinsically fully differentiable, a feature that permits the joint optimization of both the metalens structure and the parameters governing the neural network. The experimental results presented herein validate the exceptional spatial‐spectral reconstruction performance, underscoring the efficacy of this system in practical, real‐world scenarios. This innovative approach transcends the traditional boundaries separating hardware and software in the realm of computational imaging and holds the promise of substantially propelling the miniaturization of spectral imaging systems.

Virtual reality (VR) and augmented reality (AR) technology hold potential across many disciplines in medicine to expand the delivery of education and healthcare. VR-AR applications in radiology, in particular, have gained prominence and have demonstrated advantages in many areas within the field. Recently, VR software has emerged to redesign the physical radiology workstation (ie, reading room) to expand the possibilities of diagnostic interpretation. Given the novelty of this technology, there is limited research investigating the potential applications of a simulated radiology workstation. In this review article, we explore VR-simulated reading room technology in its current form and illustrate the practical applications this technology will bring to future radiologists and learners. We also discuss the limitations and barriers to adopting this technology that must be overcome to truly understand its potential benefits. VR reading room technology offers great potential in radiology, but further research is needed to appreciate its benefits and identify areas for improvement. The findings and insights presented in this review contribute to the ongoing discourse on future technological advancements in radiology and healthcare, offering valuable recommendations for further research and practical implementation.

Objective: This experiment examined performance costs when processing two sources of information positioned at increasing distances using a flat panel display and an augmented reality head-mounted display (AR-HMD). Background: The AR-HMD enables positioning virtual information at various distances in space. However, the proximity compatibility principle suggests that closer separation when two sources of information require mental integration assists performance, whereas increased separation between two sources hurts integration performance more than when a single source requires focused attention. Previous studies have provided inconsistent findings regarding costs associated with increased separation. Few of these experiments have examined separation for both focused and integration tasks, compared vertical and lateral separation, or measured head movements. Method: Three experiments collectively examined these issues using a flat panel display and a virtual display presented with an HMD, where the separation of information varied laterally or vertically during a focused attention (digit reading) task and an information integration (mental subtraction) task. Results: There was no performance cost for either display when information was increasingly separated. However, head movements mitigated performance costs by preserving accuracy at larger separations without increasing response time. Conclusion: Head movements appear to mitigate performance costs associated with presenting information increasingly far apart on flat panel displays and HMDs. Both eye scanning and head movements appear to be less effortful than expected. Application: These findings have important implications for design guidelines regarding the placement of information presented on flat panel displays and, more specifically, HMDs, which can present information 360° around the user.

This article proposes that virtual renderings of speculative architectural projects provide a crucial entry point into the reimagination of sustainable urban life through the production of nature(s) within the city. Drawing on case studies of 'sustainable' building projects in and around Amsterdam, The Netherlands, I aim to trace the entanglement of virtual and real environments in imagining green futures. With the concept of the 'render ghost', James Bridle situates the people inhabiting virtual renderings 'in the liminal space between the present and the future, the real and the virtual, the physical and the digital' (2013). Similarly, the imaginations of nature within virtual renderings of sustainable buildings are situated at a point of in-between, a constant state of becoming. More than just visualizing their respective architectural design, the virtual renderings visualize these designs in a specific space, a specific environment – and how that environment could and would change through the spatial presence of these buildings. What makes these immaterial elements – ranging from computer-generated images to virtual renderings and augmented reality applications – particularly productive as research objects is the subjective nature of the atmosphere created in and through them, an atmospheric imagination of sustainable futures embedded in what Degen et al. call a 'field of negotiation, tension and ambivalence' (2017). Atmospheric in their imagination of urban environments, contingent in their temporality between the past, the present and the future, and ambiguous in their spatial grounding in simultaneously specific and generic surroundings, virtual renderings arguably allow for an engagement with the possibilities of alternative urban futures.

Augmented reality (AR) can benefit manual assembly operations by superimposing intuitive visual guidance on the workbench directly, alleviating the mental load to determine the next operation while improving assembly performance. Where the bare-hand gesture interface is considered a promising manner to manipulate the virtual assembly model, nevertheless, it usually suffers from unreliable recognition results and poor adaptability due to the unfamiliarity with gesture libraries in actual AR assembly tasks. In this paper, we try to establish a robust and easy-to-use natural bare-hand interactive AR assembly system, enabling the operator to interact against the ongoing virtual assembly models intuitively and resulting in a human-centric AR assembly performance. Firstly, a normalized feature information extraction for real-time bare-hand gestures is presented, which can establish a robust gesture model expression when encountering different sensing distances and varying operators. Followed by the definition of some typical bare-hand interaction functions related to manual assembly operations, and thus reliable interactions between hand gestures and virtual components are available. Then, a bare-hand-enabled interactive AR assembly system is established, where operators can explore and manipulate a large amount of assembly-related information with the help of real-time bare-hand interaction. Finally, extensive experiments are carried out to evaluate the proposed bare-hand interactive AR assembly system, and results demonstrate that it can alleviate the cognitive load for the operators while providing a human-centric assembly performance.

An invisible layer of knowledge is progressively growing with the emergence of situated visualizations and reality-based information retrieval systems. In essence, digital content will overlap with real-world entities, eventually providing insights into the surrounding environment and useful information for the user. The implementation of such a vision may appear close, but many subtle details separate us from its fulfillment. This kind of implementation, as the overlap between rendered virtual annotations and the camera's real-world view, requires different computer vision paradigms for object recognition and tracking which often require high computing power and large-scale datasets of images. Nevertheless, these resources are not always available, and in some specific domains, the lack of an appropriate reference dataset could be disruptive for a considered task. In this particular scenario, we here consider the problem of wine recognition to support an augmented reading of their labels. In fact, images of wine bottle labels may not be available as wineries periodically change their designs, product information regulations may vary, and specific bottles may be rare, making the label recognition process hard or even impossible. In this work, we present augmented wine recognition, an augmented reality system that exploits optical character recognition paradigms to interpret and exploit the text within a wine label, without requiring any reference image. Our experiments show that such a framework can overcome the limitations posed by image retrieval-based systems while exhibiting a comparable performance. [ABSTRACT FROM AUTHOR]

AbstractThe importance of physical activity (PA) for overall health and well-being cannot be overstated, especially in today’s fast-paced and sedentary society. Engaging in enjoyable activities like dancing can significantly enhance PA levels and positively affect one’s mood. Advances in technology have the potential to increase individuals’ engagement in more physical activities. This work explores the effectiveness of augmented reality-driven persuasive intervention in enhancing users’ physical activity and mood. To achieve our goal, we developed AR Dancee, a mobile-driven intervention combining Augmented Reality, Machine Learning, and persuasive technology to encourage adults to increase their PA through dancing, ultimately improving their mood. A 15-day user study with 104 participants showed that the intervention effectively increased PA levels, with equal effectiveness across genders and a stronger impact on younger adults. The results also show that the intervention improved participants’ mood while reducing anxiety levels, demonstrating its potential for stress management. Overall, the contribution of this work to the HCI fields is threefold: (1) the design and development of an AR-driven persuasive mobile app, (2) providing design recommendations, and (3) pinpointing limitations and providing suggestions for future work.

People with disorders of consciousness, either as a consequence of an acquired brain injury or a traumatic brain injury, may pose serious challenges to medical and/or rehabilitative centers with an increased burden on caregivers and families. The objectives of this study were as follows: to explore the use of extended reality as a critical means of rehabilitative support in people with disorders of consciousness and brain injuries; to evaluate its impact on recovery processes; to assess the improvements in the participants' quality of life, and to reduce the burden on families and caregivers by using extended reality and artificial-intelligence-based programs. A selective review of the newest empirical studies on the use of extended reality and artificial-intelligence-based interventions in patients with brain injuries and disorders of consciousness was conducted over the last decade. The potential for bias in this selective review is acknowledged. A conceptual framework was detailed. The data showed that extended reality and artificial-intelligence-based programs successfully enhanced the adaptive responding of the participants involved, and improved their quality of life. The burden on caregivers and families was reduced accordingly. Extended reality and artificial intelligence may be viewed as crucial means of recovery in people with disorders of consciousness and brain injuries. [ABSTRACT FROM AUTHOR]

The research aims to investigate the impact of augmented reality (AR) technologies developed within the framework of primary school students' on student achievement, attitudes towards the course, attitudes towards technology, and participation in classroom activities. The contents of AR-based learning materials have been developed by 4th-grade teachers and writers within the context of the existing curriculum. The study process was carried out based on the instructional design model. The research was performed in conjunction with the quasi-experimental design among the experimental designs of quantitative research methods. Using the cluster random sampling method, students in the experimental and control groups were selected among 11 primary schools. The findings indicate that contrary to the students in the control group, the students in the experimental group had higher academic achievement and participation in classroom activities, and also their attitudes to the course and applied technology were more positive. Moreover, concerning the experimental group students, a positive and significant correlation between their academic achievements, attitudes towards the course, attitudes towards technology, and their participation and participation in classroom activities have been observed.

Augmented Reality (AR) could improve maritime collaboration by facilitating human factors like situation awareness and decision-making. However, it is not clear in which ways AR can be beneficial and for which maritime operations. This paper addresses the need for a systematic literature review of state-of-the-art ways AR can facilitate maritime collaboration. Following the PRISMA statement, we searched for the constructs "AR," "maritime operation," and "collaboration" in the Web of Science and IEEE Xplore databases. Out of 691 search results, we retained 32 publications for analysis. Ten publications from other sources were included. Our results provide a review of AR applications for the maritime operations of ship navigation, personal navigation, maritime construction, maritime maintenance and inspection, and other. We suggest that research focuses on bringing promising AR applications to higher technology readiness levels, learning from other industries, applying robust evaluation methods, and grounding more on human factors like decision-making, situation awareness, and communication.

Augmented reality (AR) can bring a new interactive experience to the collaboration between users. When users are in the same place, there are two modes of joint operation for the same object: parallel-work (PW) and cross-work (CW). PW means two users perform their tasks, while CW means assisting each other. To investigate the difference that collaboration using PW and CW in an AR environment brings to users, we developed a two-person local collaboration system, LoCol. We designed and conducted user experiments by selecting the tasks of adjusting the virtual model of the assembly and adding missing boundaries in the model. The results showed that CW led to a higher sense of social coexistence while reducing workload. In terms of task completion time and accuracy, CW and PW each had advantages. We found that users generally want to reduce unnecessary repetitive operations and frequent movement by working with others. This is likely an important criterion for determining who is better suited for a particular job in either approach. [ABSTRACT FROM AUTHOR]

Background: Painting is the foundational expression across all art forms and is one of the key creative practices for fostering students' aesthetic ability and creativity within fine arts courses. Collaborative painting in the form of socially shared regulation of learning (SSRL) can be recognized as an effective strategy for enhancing creativity in both individual and group work. However, the absence of contextual experiences and collaborative spaces poses challenges for students in cultivating their creativity in painting. Objectives: The present study explores students' creativity, socially shared regulation (SSR) and positive painting behaviours using an SSRL‐based collaborative painting approach in the metaverse (Meta‐CP). Methods: Via a quasi‐experimental design, a total of 40 Chinese students in fifth grade were recruited and were randomly divided into an experimental group and a control group, with 20 students utilizing the Meta‐CP approach, while the remaining 20 students followed the conventional SSRL‐based paper‐and‐brush collaborative painting (C‐CP) approach. The Meta‐CP approach not only offers an authentic painting context and a collaborative space but also facilitates the collaborative process through the SSRL framework. The data collection included students' creative tendency, painting works and painting process. Results and Conclusions: The Meta‐CP approach effectively enhances students' creativity concerning adventure, curiosity and imagination, as well as results in the creation of more distinctive and logical artistic works. Furthermore, the approach significantly improved the quality of students' SSR. Additionally, students utilizing the Meta‐CP approach displayed more positive painting behaviours compared with those employing the C‐CP approach. Lay Description: What is already known about this topic:Collaborative painting is an effective strategy for enhancing creativity.Socially shared regulation of learning (SSRL) fosters collaborative learning.Students in collaborative painting may lack a contextual and synchronized painting space.The metaverse benefits in terms of contextual experiences and collaborative spaces. What this paper adds:Using an SSRL‐based collaborative painting approach in the metaverse (Meta‐CP) is effective in improving students' creativity.The Meta‐CP approach has the potential to improve students' quality of socially shared regulation (SSR), and positive painting behaviours. Implications for practice and/or policy:The metaverse provides an immersive synchronized painting space for art education to stimulate students' creative potential.The metaverse with proper learning strategies (e.g., SSRL) provides an effective collaborative learning environment for creation.
