<p>Two projects are introduced: a cooperative game aimed at fostering behavioral, cognitive and meta-cognitive skills within organizations (Holo-Transportation), and a technical procedure aimed at saving lives (Holo-Defibrillation). e-REAL was the educational setting: an environment where physical and digital objects co-exist and interact in real time.Both the two projects were self-instruction learning simulation programs developed to maximize learning results, reducing instructor intervention and cost. Cascading and growing technical know-how about defibrillation was the main target of Holo-Defibrillation, while Holo-Transportation was aimed at empowering teamwork by fostering cognitive flexibility, emotional intelligence and self-awareness, as well as at honing the epistemic acumen related to reviewing ongoing processes and procedures, errors and alternative options.</p>

Objective Augmented reality (AR) is a rapidly developing technology. The aim of this systematic review was to (1) identify and evaluate applications of AR in otolaryngology and (2) examine trends in publication over time. Data Sources PubMed and EMBASE. Review Methods A systematic review was performed according to PRISMA guidelines without temporal limits. Studies were included if they reported otolaryngology-related applications of AR. Exclusion criteria included non-English articles, abstracts, letters/commentaries, and reviews. A linear regression model was used to compare publication trends over time. Results Twenty-three articles representing 18 AR platforms were included. Publications increased between 1997 and 2018 ( P < .05). Twelve studies were level 5 evidence; 9 studies, level 4; 1 study, level 2; and 1 study, level 1. There was no trend toward increased level of evidence over time. The most common subspecialties represented were rhinology (52.2%), head and neck (30.4%), and neurotology (26%). The most common purpose of AR was intraoperative guidance (54.5%), followed by surgical planning (24.2%) and procedural simulations (9.1%). The most common source of visual inputs was endoscopes (50%), followed by eyewear (22.2%) and microscopes (4.5%). Computed tomography was the most common virtual input (83.3%). Optical trackers and fiducial markers were the most common forms of tracking and registration, respectively (38.9% and 44.4%). Mean registration error was 2.48 mm. Conclusion AR holds promise in simulation, surgical planning, and perioperative navigation. Although level of evidence remains modest, the role of AR in otolaryngology has grown rapidly and continues to expand.

Obtaining adequate and precise anatomical information is mandatory to prevent vascular access–related complications in dialysis patients. For this purpose, we underwent Doppler ultrasound, vascular access angiogram, and plain computer-assisted tomography scan of the arm with vascular access. With the use of computer graphics software, the anatomical structure of the vascular access can be visualized three dimensionally which is shared among the staffs for precise and better recognition. Furthermore, created object is applicable for virtual reality and/or augmented reality presentation that provides useful means for education and practical procedures in the management of vascular access.

The use of augmented reality (AR) and virtual reality (VR) for life support training is increasing. These technologies provide an immersive experience that supports learning in a safe and controlled environment. This review focuses on the use of AR and VR for emergency care training for health care providers, medical students, and nonprofessionals. In particular, we analyzed (1) serious games, nonimmersive games, both single-player and multiplayer; (2) VR tools ranging from semi-immersive to immersive virtual and mixed reality; and (3) AR applications. All the toolkits have been investigated in terms of application goals (training, assessment, or both), simulated procedures, and skills. The main goal of this work is to summarize and organize the findings of studies coming from multiple research areas in order to make them accessible to all the professionals involved in medical simulation. The analysis of the state-of-the-art technologies reveals that tools and studies related to the multiplayer experience, haptic feedback, and evaluation of user’s manual skills in the foregoing health care-related environments are still limited and require further investigation. Also, there is an additional need to conduct studies aimed at assessing whether AR/VR-based systems are superior or, at the minimum, comparable to traditional training methods.

Virtual Reality (VR) is becoming a mature technology field. To understand its origins and foresee strategies, a study on the last decade of papers published in the Brazilians´ most prominent symposium (the SVR – Symposium on Virtual and Augmented Reality) has been carried out. Papers were classified according to subject of study (including application domains, sub-areas and technologies, among others) as well asresearch structure (including authorship counts and geographical distribution, research approaches, among others). The study shows that health related applications have received most of the attention although techniques and tools proposal have raised the most recently which could be related to the lowlevel programming languages and frameworks preferences found to this community. The number of Augmented Reality (AR) papers has grown steadily and a great variety of underlying knowledge fields (such as 3D interaction and real-time simulation) is a persistent aspect of SVR. Data also show that expected shift from VRML to other 3D Web technologies have already happened. Although oversees participation has been not constant, papers published in English has proven stable in SVR editions. Few institutions from Southeast have dominated the research area but another few from Northeast have just surpassed them. Regarding the research, a lack of higher-level maturity research approaches has been noticed. In addition, it was found difficult to assess the relevance of papers to other researches due to poor abstracts and no centralized database of papers. The analysis of 262 papers suggest that (i) by improving the research budget to the area could impact productivity; (ii) a centralized database would facilitate recovering past contributions and; (iii) that enforcing more scientifically rigorous papers with better abstracts and written in English could raise the visibility of Brazilians´ research in VR/AR.

Full textAbstract:
Augmented reality (AR) is an emerging technology that allows users to interact with simulated environments, including those emulating scenes in the real world. Most current AR technologies involve the placement of virtual objects within these scenes. However, difficulties in modeling real-world objects greatly limit the scope of the simulation, and thus the depth of the user experience. In this study, we developed a process by which to realize virtual environments that are based entirely on scenes in the real world. In modeling the real world, the proposed scheme divides scenes into discrete objects, which are then replaced with virtual objects. This enables users to interact in and with virtual environments without limitations. An RGB-D camera is used in conjunction with simultaneous localization and mapping (SLAM) to obtain the movement trajectory of the user and derive information related to the real environment. In modeling the environment, graph-based segmentation is used to segment point clouds and perform object segmentation to enable the subsequent replacement of objects with equivalent virtual entities. Superquadrics are used to derive shape parameters and location information from the segmentation results in order to ensure that the scale of the virtual objects matches the original objects in the real world. Only after the objects have been replaced with their virtual counterparts in the real environment converted into a virtual scene. Experiments involving the emulation of real-world locations demonstrated the feasibility of the proposed rendering scheme. A rock-climbing application scenario is finally presented to illustrate the potential use of the proposed system in AR applications.

Full textAbstract:
Augmented reality is well known for extending the real world by adding computer-generated perceptual information and overlaid sensory information. In contrast, simulation worlds are commonly closed and rely on artificial sensory information generated by the simulator program or using data collected off-line. In this work, a new simulation paradigm is introduced, providing augmented virtuality by integrating crowd sensing and social data mining in simulation worlds by using mobile agents. The simulation world interacts with real world environments, humans, machines, and other virtual worlds in real-time. Mobile agents are closely related to bots that can interact with humans via chat blogs. Among the mining of physical sensors (temperature, motion, position, light, …), mobile agents can perform Crowd Sensing by participating in question–answer dialogs via a chat blog provided by a WEB App that can be used by the masses. Additionally, mobile agents can act as virtual sensors (offering data exchanged with other agents). Virtual sensors are sensor aggregators performing sensor fusion in a spatially region.

Full textAbstract:
The article is tasked with studying the modern possibilities and effectiveness of the application of virtual and augmented reality technologies in the field of managing human recourses (HRs) and basic operational corporate business processes. Using examples of successful use of AR (augmented reality)/VR (virtual reality) in the labor market by the largest companies in the USA, China, and Europe, the most relevant areas and forms of using these technologies in the work of HR specialists were considered. The study examined issues related to improving the performance of the main modern vectors of corporate development in the field of operational technological improvements, and, as the main result, a model of the company (organization) development was proposed based on improved management of business and HR processes using VR and AR tools. The developed model demonstrates the advantages of using it, and presents the reasons for the economic expediency of using these technologies at all stages of personnel management, including recruiting, staff selection, demonstration of the employer’s brand, testing candidates’ skills, improving internal communications, creating a positive corporate culture for employees, imitating the workflow, VR and AR-simulations as a tool for passing the input testing for recruitment, selection and management of remote employees, training, assessment, and adaptation of staff. The possibilities of using VR/AR as tools for operational improvements (lean management), for example, for organizing virtual business meetings and meetings, creating virtual presentations, online controlling in the manufacturing sector, automating operational processes, and using VR technologies, are also separately disclosed in the management of logistics, distribution, marketing, and advertising. The results of the analysis of theoretical and statistical sources of information showed the promise of using the possibilities of virtual reality in corporate management, which shifts the emphasis from the traditional understanding and perception of these technologies exclusively in the entertainment field. The obtained developments within the framework of the conducted research are universal in nature and can be applicable both in the study of modern methods of personnel management and in corporate lean management of modern business companies at various levels.

The use of virtual worlds in health-related education is increasingly popular, but an overview of their use in physiotherapy education is still needed. The aim of this review was to analyse the use of virtual and augmented reality (VR/AR) compared to traditional methods for teaching physiotherapy. A systematic review was performed up to October 2022 in PubMed, Web of Science, Scopus, CINAHL, and PsycInfo. The quality appraisal and risk of bias were assessed by the Joana Briggs Institute checklist and the Cochrane Collaboration’s RoB Tool 2.0, respectively. A total of seven randomised and non-randomised controlled studies were included, involving 737 students. VR/AR-based teaching approaches included simulation and virtual worlds, and were conducted through immersive head-mounted displays, AR-based applications, and 3D visualisations. Three studies were focused on teaching anatomy content, two on clinical decision making skills, and the rest were focused on pathology, physiotherapy tasks or exercise performance, and movement analysis of lower limbs. Inconclusive results were found in terms of learning satisfaction and academic performance, showing VR/AR-based teaching models to be equally effective as traditional methods for teaching physiotherapy. We encourage researchers and teachers to include games in their VR/AR-based teaching approaches to enhance interaction and active learning in physiotherapy education.

Full textAbstract:
Schizophrenia is a chronic mental disease that usually manifests psychotic symptoms and affects an individual’s functionality. The stigma related to this disease is a serious obstacle for an adequate approach to its treatment. Stigma can, for example, delay the start of treatment, and it creates difficulties in interpersonal and professional relationships. This work proposes a new tool based on augmented reality to reduce the stigma related to schizophrenia. The tool is capable of simulating the psychotic symptoms typical of schizophrenia and simulates sense perception changes in order to create an immersive experience capable of generating pathological experiences of a patient with schizophrenia. The integration into the proposed environment occurs through immersion glasses and an embedded camera. Audio and visual effects can also be applied in real time. To validate the proposed environment, medical students experienced the virtual environment and then answered three questionnaires to assess (i) stigmas related to schizophrenia, (ii) the efficiency and effectiveness of the tool, and, finally (iii) stigma after simulation. The analysis of the questionnaires showed that the proposed model is a robust tool and quite realistic and, thus, very promising in reducing stigma associated with schizophrenia by instilling in the observer a greater comprehension of any person during an schizophrenic outbreak, whether a patient or a family member.

Full textAbstract:
Purpose: This study aimed to investigate the effects of virtual reality used in maternal-child nursing clinical practicums on nursing students’ competencies through a systematic review.Methods: The inclusion criteria were peer-reviewed papers in English or Korean presenting analytic studies of maternal-child nursing practicums using virtual reality. An electronic literature search of the Cochrane Library, CINAHL, EMBASE, ERIC, PubMed, and Research Information Sharing System databases was performed using combinations of the keywords “nursing student,” “virtual reality,” “augmented reality,” “mixed reality,” and “virtual simulation” from February 4 to 15, 2022. Quality appraisal was performed using the RoB 2 and ROBINS-I tools for randomized controlled trials (RCTs) and non-RCTs, respectively.Results: Of the seven articles identified, the RCT study (n=1) was deemed to have a high risk of bias, with some items indeterminable due to a lack of reported details. Most of the non-RCT studies (n=6) had a moderate or serious risk of bias related to selection and measurement issues. Clinical education using virtual reality had positive effects on knowledge, skills, satisfaction, self-efficacy, and needs improvement; however, it did not affect critical thinking or self-directed learning.Conclusion: This study demonstrated that using virtual reality for maternal-child nursing clinical practicums had educational effects on a variety of students’ competencies. Considering the challenges of providing direct care in clinical practicums, virtual reality can be a viable tool that supplements maternal-child nursing experience. Greater rigor and fuller reporting of study details are required for future research.

This study explores the complexity of the connection between Pokémon Go play experience and players’ affection toward their physical surroundings from the environmental psychology and the media entertainment perspectives. The survey results of a stratified sample of 1,088 respondents showed that four dimensions of perceived realism—simulational realism, freedom of choice, integrated presence, and perceptual pervasiveness—positively influenced game enjoyment. Co-presence positively predicted game enjoyment while perceived crowding was negatively related to game enjoyment. Game involvement partially mediated the relationship between co-presence and game enjoyment, and game involvement also mediated the relationship between game enjoyment and place attachment. Theoretical implications on linking human behaviors and their affectional connections to physical places via the virtual gaming world are also discussed.

Background Shortages in qualified supervision and other resources prevent education personnel from rehearsing effective practices. Interactive simulations, although increasingly used in education, frequently require instructor management. Automated simulations rarely engage trainees in skills related to practice (eg, speech). Objective We evaluated the capability of delivering behavioral skills training through an automated virtual reality (VR) simulation using artificial intelligence to improve the implementation of a nondirective mathematical questioning strategy. Methods We recruited and randomly assigned 30 college-aged participants to equivalent treatment (ie, lecture, modeling, and VR; 15/30, 50%) and control groups (ie, lecture and modeling only; 15/30, 50%). The participants were blind to treatment conditions. Sessions and assessments were conducted face to face and involved the use of VR for assessment regardless of the condition. Lessons concerned the use of a nondirective mathematical questioning strategy in instances where a simulated student provided correct or incorrect answers to word problems. The measures included observed and automated assessments of participant performance and subjective assessments of participant confidence. The participants completed the pretest, posttest, and maintenance probes each week over the course of 3 weeks. Results A mixed ANOVA revealed significant main effects of time (F2,27=124.154; P<.001; ηp2=0.816) and treatment (F1,28=19.281; P<.001; ηp2=0.408) as well as an interaction effect (F2,28=8.429; P<.001; ηp2=0.231) for the average percentage of steps in the questioning procedure. Posttest scores for the intervention group (mean 88%, SD 22.62%) exceeded those of the control group (mean 63.33%, SD 22.64%), with t28=3.653, P<.001, and Cohen d=1.334. Maintenance scores indicated a positive effect of the intervention (mean 83.33%, SD 24.40%) relative to the control (mean 54.67%, SD 15.98%), t28=3.807, P<.001, Cohen d=1.39. A Mann-Whitney U test indicated that the treatment groups’ self-ratings of confidence (mean 2.41, SD 0.51) were higher than those of the control group (mean 2.04, SD 0.52), U=64, P=.04, r=0.137. Conclusions The results demonstrate the potential of artificial intelligence-augmented VR to deliver effective, evidence-based training with limited instructor management. Additional work is needed to demonstrate the cascading effect of training on authentic practice and to encompass a wider range of skills.

Abstract The developments of the fourth industrial revolution have caused changes in all areas of society, including production. The changes in production caused by the fourth industrial revolution have also resulted in fundamental changes in the supply chain and have converted it to supply chain 4.0. Organisations must be receptive to supply chain 4.0 to maintain their competitive advantage. Therefore, this study aimed to investigate the relationships among supply chain 4.0 technologies so that, by learning and understanding these connections, industries can pave the way for the implementation of these technologies in their supply chains and use them in problem-solving. The literature review was used to identify the supply chain 4.0 technologies, and the Delphi technique was applied to extract them, including the Internet of Things (IoT), cyber-physical systems, cloud computing, big data, blockchain, artificial intelligence, Radio-frequency Identification (RFID), augmented reality, virtual reality, and simulation. The relationships of supply chain 4.0 technologies were examined using the DEMATEL technique and based on interpretive structural modelling (ISM), their deployment map was drawn. The type of technologies was determined using the MICMAC method. The MICMAC analysis found that the artificial intelligence technology is independent and, based on the findings through the DEMATEL technique, this technology is related to simulation, which belongs to the first level of the interpretive structural modelling technique, and IoT, cloud computing, big data, and blockchain technologies, which are at the second level. Based on the ISM method, RFID, virtual reality, augmented reality and simulation technologies are located at the first level; IoT, cyber-physical systems, cloud computing, big data and blockchain technologies are situated in the second level; and artificial intelligence technology belongs to the third level. According to the related literature, few studies have been conducted on the issues of supply chain 4.0 and the technologies that affect it.

Full textAbstract:
Currently, the System of Rice Intensification (SRI) is one method that can be applied and used to produce seeds of local rice species in highland areas. However, it can currently be seen that the traditional methods to transfer knowledge about SRI from the experts still have limitations in many aspects due to the number of farmers that have experienced success still being low. Some farmers do not have their own fields and it takes a period for farmers to test the rice growing. Currently, mobile devices are widely used in peoples’ lives. Many scholars focus on the application of mobile devices and the augmented reality (AR) technology for the simulation games in many issues while the use of AR-based mobile applications as the learning tools is not widespread. There-fore, in this study, we propose the development of an application on mobile devices with augmented reality technology in order to use it as media in sharing knowledge related to the methods of the System of Rice Intensification by virtual farms simulation. To examine the efficiency of this developed application. A total amount of participants were 512 farmers from 5 regions of Thailand. The experimental results demonstrated that the newly developed AR-based mobile application is effective for improved knowledge on the participants who used the developed application and it can help them to practice their SRI farming skill in the virtual farm simulation. This indicates that the developed AR-based mobile application is the benefits tool for the new knowledge transferring meth-od in the system of rice intensification. For future work, it is necessary to evaluate the farmer success after learning from this AR-based mobile application in order to study the impact of the new method of SRI knowledge transferring.
Keywords—augmented reality, knowledge transferring, system of rice intensification.

Full textAbstract:
PURPOSE Limited access to adequate cancer surgery training is one of the driving forces behind global inequities in surgical cancer care. Affordable virtual reality (VR) surgical training could enhance surgical skills in low- and middle-income settings, but most VR and augmented reality systems are too expensive and do not teach open surgical techniques commonly practiced in these contexts. New low-cost VR can offer skill development simulations relevant to these settings, but little is known about how knowledge is gained and applied by surgeons training and working in specific resource-constrained settings. This study addresses this gap, exploring gynecologic oncology trainee learning and user experience using a low-cost VR simulator to learn to perform an open radical abdominal hysterectomy in Lusaka, Zambia. METHODS Eleven surgical trainees rotating through the gynecologic oncology service were sequentially recruited from the University Teaching Hospital in Lusaka to participate in a study evaluating a VR radical abdominal hysterectomy training designed to replicate the experience in a Zambian hospital. Six participated in semi-structured interviews following the training. Interviews were analyzed using open and axial coding, informed by grounded theory. RESULTS Simulator participation increased participants' perception of their surgical knowledge, confidence, and skills. Participants believed their skills transferred to other related surgical procedures. Having clear goals and motivation to improve were described as factors that influenced success. CONCLUSION For cancer surgery trainees in lower-resourced settings learning medical and surgical skills, even for those with limited VR experience, low-cost VR simulators may enhance anatomical knowledge and confidence. The VR simulator reinforced anatomical and clinical knowledge acquired through other modalities. VR-enhanced learning may be particularly valuable when mentored learning opportunities are limited.

Objective Extended reality technologies (e.g. virtual reality (VR), augmented reality (AR) and mixed reality (MR)) are gaining popularity in sports owing to their unique advantages. This study aims to analyse the progress of the application of extended reality technology in sports and reveal its cooperative features, research hotspots and development trends. Methods We searched the literature in the Web of Science Core Collection (WoSCC) database within the period 2000 to 2021 and conducted a bibliometric analysis. The analysis methods included statistical, co-occurrence, hierarchical clustering and social network analyses. Results A total of 340 articles were gathered. The literature related to its research showed an increasing trend over time. The paper collaboration rate was 90.88% (309/340 papers), and the degree of author collaboration was 3.96 (1345/340). VR was found to be the most productive journal, and Queen's University Belfast was the most productive institution. The United States, China and the United Kingdom were the three main contributors to the field. The foundational themes in sports extended reality research were (i) sports games and extended reality systems, (ii) virtual simulation devices and artificial intelligence, (iii) sports training and performance and (iv) age-appropriate physical activity, sports rehabilitation and physical education. Conclusion The level of author collaboration was low, but the degree of author collaboration is largely on the rise. The closeness of the collaboration between institutions and countries was also low. In addition, the subject of sport extended reality is relatively fragmented. Therefore, more research is needed to strengthen it in the future.

Full textAbstract:
Data and services are available anywhere at any time thanks to the Internet and mobile devices. Nowadays, there are new ways of representing data through trendy technologies such as augmented reality (AR), which extends our perception of reality through the addition of a virtual layer on top of real-time images. The great potential of unmanned aerial vehicles (UAVs) for carrying out routine and professional tasks has encouraged their use in the creation of several services, such as package delivery or industrial maintenance. Unfortunately, drone piloting is difficult to learn and requires specific training. Since regular training is performed with virtual simulations, we decided to propose a multiplatform cloud-hosted solution based in Web AR for drone training and usability testing. This solution defines a configurable trajectory through virtual elements represented over barcode markers placed on a real environment. The main goal is to provide an inclusive and accessible training solution which could be used by anyone who wants to learn how to pilot or test research related to UAV control. For this paper, we reviewed drones, AR, and human–drone interaction (HDI) to propose an architecture and implement a prototype, which was built using a Raspberry Pi 3, a camera, and barcode markers. The validation was conducted using several test scenarios. The results show that a real-time AR experience for drone pilot training and usability testing is achievable through web technologies. Some of the advantages of this approach, compared to traditional methods, are its high availability by using the web and other ubiquitous devices; the minimization of technophobia related to crashes; and the development of cost-effective alternatives to train pilots and make the testing phase easier for drone researchers and developers through trendy technologies.

Students in the twenty-first century are accustomed to using technology in all aspects of their lives and have never known a world without it; the classroom is no exception. Augmented reality (AR) is a technology that bridges the virtual and physical worlds to make learning more engaging and enjoyable. In this paper, we present a mobile application aimed at novice learners that makes use of technology for the teaching and learning of computer system engineering concepts. Currently, students typically learn about finite-state machine (FSM) concepts from lectures, tutorials, and practical hands-on experience combined with commercial timing simulation tools. We aimed to enhance these traditional, lecture-based instruction and information delivery methods. We developed an AR-based FSM visualization tool called AR4FSM to help students more easily grasp concepts through immersion and natural interaction with an FSM. We used a blend of multimedia information, such as text, images, sound, and animations superimposed on real-world-state machine diagrams, presenting the information in an interactive and compelling way. An experiment with 60 students showed that the app was perceived positively by the students and helped to deliver FSM-related concepts in a way that was easier to understand than traditional, lecture-based teaching methods. This instruction methodology not only engaged the students but also motivated them to learn the material. The findings of this study have inspired us to use this application to teach FSM topics in the classroom.

Holographic near-eye displays promise unprecedented capabilities for virtual and augmented reality (VR/AR) systems. The image quality achieved by current holographic displays, however, is limited by the wave propagation models used to simulate the physical optics. We propose a neural network-parameterized plane-to-multiplane wave propagation model that closes the gap between physics and simulation. Our model is automatically trained using camera feedback and it outperforms related techniques in 2D plane-to-plane settings by a large margin. Moreover, it is the first network-parameterized model to naturally extend to 3D settings, enabling high-quality 3D computer-generated holography using a novel phase regularization strategy of the complex-valued wave field. The efficacy of our approach is demonstrated through extensive experimental evaluation with both VR and optical see-through AR display prototypes.

Full textAbstract:
Attention Deficit Hyperactivity Disorder is one of the most common neurodevelopmental disorders in which patients have difficulties related to inattention, hyperactivity, and impulsivity. Those patients are in need of a psychological therapy use Cognitive Behavioral Therapy (CBT) to enhance the way they think and behave. This type of therapy is mostly common in treating patients with anxiety and depression but also is useful in treating autism, obsessive compulsive disorder and post-traumatic stress disorder. A major limitation of traditional CBT is that therapists may face difficulty in optimizing patients’ neuropsychological stimulus following a specified treatment plan. Other limitations include availability, accessibility and level-of-experience of the therapists. Hence, this paper aims to design and simulate a generic cognitive model that can be used as an appropriate alternative treatment to traditional CBT, we term as “AR-Therapist.” This model takes advantage of the current developments of augmented reality to engage patients in both real and virtual game-based environments.

Full textAbstract:
Purpose This study aims to discern emerging trends and provide a longitudinal perspective on merchandising research by identifying relationships between merchandising-related subdomains/themes. Design/methodology/approach This study sourced 657 merchandising-related articles published since 1960, from the Scopus database and 425 from Web of Science. After processing and normalizing the data, this study performed co-word and thematic network analyses. Taking a text mining approach, this study used topic modeling to identify a set of coherent topics characterized by the keywords of the articles. Findings This study identified the following merchandising-related themes: branding, retail, consumer, behavior, modeling, textile and clothing industry and visual merchandising. Although visual merchandising was the first type of merchandising to be used in-store, only recently has it become an emerging topic in the academic literature. There has been a further trend over the past decade to understand the adoption of simulation technology, such as computer-aided design, particularly in supply chain management in the clothing industry. These and other findings contribute to the discussion of the merchandising concept, approached from an evolutionary perspective. Research limitations/implications The conclusions of this study hold implications at the intersection of merchandising, sectors, new technologies, research methodologies and merchandising-practitioner education. Research trends suggest that, in the future, virtual reality and augmented reality using neuroscientific methods will be applied to the e-merchandising context. Practical implications The different dimensions of merchandising can be used to leverage store managers’ decision-making process toward an integrated store-management strategy. In particular, by adopting loyalty merchandising tactics, the store can generate emotional attachment among consumers, who will perceive its value and services as unique, thanks to merchandising items designed specifically with that aim in mind. The stimulation of unplanned purchases, the strategic location of products and duration of each merchandising activity in the store, the digitalization of merchandising and the application of findings from neuroscience studies are some of the most relevant practical applications. Originality/value This study provides the first-ever longitudinal review of the state of the art in merchandising research, taking a holistic perspective of this field of knowledge spanning a 60-year period. The work makes a valuable contribution to the development of the marketing discipline.

Full textAbstract:
Virtual, Augmented and Mixed Reality (XR) technologies are becoming increasingly pervasive. However, the contextual nature of XR, and its tight coupling of the digital and physical environments, brings real propensity for loss and harm. This means that auditability---the ability to inspect how a system operates---will be crucial for dealing with incidents as they occur, by providing the information enabling rectification, repair and recourse. However, supporting audit in XR brings considerations, as the process of capturing audit data itself has implications and challenges, both for the application (e.g., overheads) and more broadly. This paper explores the practicalities of auditing XR systems, characterises the tensions between audit and other considerations, and argues the need for flexible tools enabling the management of such. In doing so, we introduce Droiditor, a configurable open-source Android toolkit that enables the runtime capture of audit-relevant data from mobile applications. We use Droiditor as a means to indicate some potential implications of audit data capture, demonstrate how greater configurability can assist in managing audit-related concerns, and discuss the potential considerations that result. Given the societal demands for more transparent and accountable systems, our broader aim is to draw attention to auditability, highlighting tangible ways forward and areas for future work.

In principle, in the Polish nomenclature, the term is so new that it is often confused, incomprehensible. This, in turn, translates into misunderstanding and the lack of the use of this communication channel. The article is a review of literature. In the first part concepts such as augmented reality, augmented virtuality, mixed reality, virtual reality, and immersion will be explained. A short historical outline of the virtual reality will also be shown. Then - in the next part of the article - the author compares this communication channel with well-known, such as the Internet, television, radio. Next the author will determine what are the fields of application of this communication channel and its condition.

Therefore, technologies related to Augmented Reality (AR) and Virtual Reality (VR) are rapidly and prominently positioning themselves in the medical sector, and the field of ophthalmology is growing exponentially both in terms of the training of professionals and in the assistance and recovery of patients. At the same time, it is necessary to highlight and analyze the developments that have made use of game technologies for the teaching of ophthalmology and the results that have been obtained. This systematic review aims to investigate software and hardware applications developed exclusively for educational environments related to ophthalmology and provide an analysis of other related tools.

Full textAbstract:
Older adults face significant loss and limitations in terms of mobility, cognitive ability, and socialization. By using augmented reality and virtual reality technologies they have the potential to overcome such loss and limitations, and to eventually improve their quality of life. However, this group is often excluded in augmented reality and virtual reality deployment. Further, limited studies address their challenges when using augmented reality and virtual reality. Therefore, for a critical review of augmented reality and virtual reality for older adults, we developed a framework to evaluate related factors, including physical, social, and psychological wellbeing. Through the critical review, we identified that most augmented reality and virtual reality studies focus on physical wellbeing of older adults but also make substantial efforts to increase their psychological wellbeing. Fun factors that would motivate them are also extensively considered. Further, social isolation continues to be a significant issue for older adults, but the appropriate content to increase their social wellbeing is insufficient, although many commercial products have been developed. The contribution of the present study is to provide a contextual framework and an evaluation framework for the critical review of augmented reality and virtual reality technologies to promote wellbeing in older adults. This study also suggests the augmented reality and virtual reality research direction for studies on this group by identifying the research gap through the critical review process. Lastly, this study investigates design directions of augmented reality and virtual reality for older adults by introducing challenges and design issues that emerged through the critical review.

Abstract Background and Purpose. Recent evidence indicates that intensive massed practice may be necessary to modify neural organization and effect recovery of motor skills in patients following stroke. Virtual reality (VR) technology has the capability of creating an interactive, motivating environment in which practice intensity and feedback can be manipulated to create individualized treatments to retrain movement. Case Description. Three patients (ML, LE, and DK), who were in the chronic phase following stroke, participated in a 2-week training program (3½ hours a day) including dexterity tasks on real objects and VR exercises. The VR simulations were targeted for range of motion, movement speed, fractionation, and force production. Outcomes. ML's function was the most impaired at the beginning of the intervention, but showed improvement in the thumb and fingers in range of motion and speed of movement. LE improved in fractionation and range of motion of his thumb and fingers. DK made the greatest gains, showing improvement in range of motion and strength of the thumb, velocity of the thumb and fingers, and fractionation. Two of the 3 patients improved on the Jebsen Test of Hand Function. Discussion. The outcomes suggest that VR may be useful to augment rehabilitation of the upper limb in patients in the chronic phase following stroke.

One of the strategies to create this interaction is related to the application of virtual and augmented reality in the teaching-learning processes. Through a systematic literature review, this work aims to describe the approaches used to measure the impacts on student learning who used virtual reality (VR) and augmented reality (AR) in the teaching-learning processes of engineering courses, the impacts on learning, and student satisfaction. The surveys showed that 70% of research analyzed, students who used virtual reality or augmented reality learned more, and 90% of the research described that students who used virtual or augmented reality were more satisfied with the new approach than the traditional teaching approach. The conclusion is that there are positive impacts, in the vast majority of cases, on learning and the satisfaction of students who use virtual or augmented reality in the teaching-learning processes applied in engineering courses.

VR and AR technology have gradually developed to the extent that they could help operators in the surgical field. In this study, we present a case of VR simulation for preoperative planning and AR navigation applied to orthognathic surgery. The average difference between the preplanned data and the post-operative results was 3.00 mm, on average, and the standard deviation was 1.44 mm. VR simulation could provide great advantages for 3D medical simulations, with accurate manipulation and immersiveness. AR navigation has great potential in medical application; its advantages include displaying real time augmented 3D models of patients. Moreover, it is easily applied in the surgical field, without complicated 3D simulations or 3D-printed surgical guides.

Use of a physics engine to drive a virtual scene is becoming more common. Physics simulations aim to model the behaviors of objects in space so as to provide realistic motions in computer animation, thereby enriching the interaction and user experience in augmented reality. In this paper, we present a cross-platform environment in which handheld and desktop-computer users can collaborate with each other in a shared scene to accomplish physically realistic experiences during the course of interaction. In realizing the system, we explore and exploit several novel techniques, including bare-hand manipulation, a client/server computing framework, a tangible mobile phone interface, and a distributed scene graph structure. To demonstrate the effectiveness of the system, we developed JengAR, a simulation of the well-known tower building game

The idea of virtuality is not new, as research on visualization and simulation dates back to the early use of ink and paper sketches for alternative design comparisons. As technology has advanced so the way of visualizing simulations as well, but the progress is slow due to difficulties in creating workable simulations models and effectively providing them to the users. Augmented Reality and Virtual Reality, the evolving technologies that have been haunting the tech industry, receiving excessive attention from the media and colossal growing are redefining the way we interact, communicate and work together. From consumer application to manufacturers these technologies are used in different sectors providing huge benefits through several applications. In this work, we demonstrate the potentials of Augmented Reality techniques in a Smart City (Smart Campus) context. A multiplatform mobile app featuring Augmented Reality capabilities connected to GIS services are developed to evaluate different features such as performance, usability, effectiveness and satisfaction of the Augmented Reality technology in the context of a Smart Campus.

Master lectures of history are usually quite boring for the students, and to keep their attention requires a great effort from teachers. Virtual and Augmented Reality have a clear potential in education and can solve this problem. Serious games that use immersive technologies allow students to visit and interact with environments dated in different ages. Taking this in mind, this article presents a playful virtual reality experience set in Ancient Rome that allows the user to learn concepts from that age. The virtual experience reproduces as accurately as possible the different buildings and civil constructions of the time, making it possible for the player to create Roman cities in a simple way. Once built, the user can visit them, accessing the buildings and being able to interact with the objects and characters that appear. Moreover, in order to learn more information about every building, users can visualize them using Augmented Reality using marker-based techniques. Different information has been included related to every building, such as their main uses, characteristics, or even some images that represent them. In order to evaluate the effectiveness of the developed experience, several experiments have been carried out, taking as sample Secondary School students. Initially, the game’s quality and playability has been evaluated and, subsequently, the motivation of the virtual learning experience in history. The results obtained support on the one hand its gameplay and attractiveness, and on the other, the student’s increased interest in studying history, as well as the greater fixation of different concepts treated in a playful experience.

Objectives The purpose of this study is to examine research trends on VR/AR-based CPR training to provide key information on VR/AR-based CPR training, to explore utilization methods of VR/AR in CPR training in South Korea and directions for future research. Methods Cochrane Library, EMBASE, Medline, and PubMed were searched using keywords from ‘Virtual reality (VR)’, ‘Augmented reality (AR)’, ‘Cardiopulmonary Resuscitation (CPR)’, and ‘Basic Life Support (BLS)’. Among 1,065 academic articles obtained, 29 papers meeting the criteria were selected by reading the titles and abstracts and excluding papers unrelated to the topic and duplicates. The research design, method, and main results of each literature were scrutinized. Results Research related to CPR training using VR/AR technology has recently increased rapidly, mainly in the United States and European countries. Many are to check the usability of equipment/devices used VR/AR technology or to explore the user's perspectives, and some to see the effects of training for health care workers and college students in related areas. The use of VR/AR in CPR training appeared in various ways regarding the method of platform and feedback. VR/AR based CPR training is an attractive approach, and positive training outcomes are reported but some are not. Conclusions The advantages of VR/AR based CPR training are clear, but the training method is not standardized and remains in the stage of dissemination, thus it should be careful in interpreting it as effective enough to replace traditional CPR training. In South Korea, it is needed to use VR/AR technology as an auxiliary in CPR training to take advantage of its benefits and to increase in research with high level of evidence.

Augmented reality (AR) and virtual reality (VR) are expanding into various fields of education. Thanks to AR and VR, teachers can bring a whole new dimension to the realm of language education, resulting in enhanced learning and increased motivation and engagement. With smartphones and inexpensive VR headsets, teachers are able to take a step forward in blurring the boundaries between the real and virtual worlds, giving their students immersive learning experiences. However, many ELT practitioners are not familiar with or keen on integrating AR/VR-related learning tools and resources into their classes (Bonner & Reinders, 2018; Santos et al., 2016). To get readers more acquainted with AR/VR uses in language education, the author first outlines the basic concepts within this area of research and practice. An AR/VR application is introduced in detail, followed by discussion on the use of this app in language learning. 拡張現実（AR）および仮想現実（VR）は絶えず様々な教育分野に拡大している。ARとVRによって、学習の強化やモチベーションとエンゲージメントの向上が可能となり、言語教育の領域に全く新しい次元をもたらすことができる。スマートフォンや安価なVRヘッドセットの使用によって、現実世界と仮想世界の境界を曖昧にすることで、学生は没入型の学習体験を得られる。しかし、ELT実務家の多くは、AR・VR関連の学習ツールとリソースを教育実践に統合する方法に馴染みがなかったり、統合自体に関心がない現状がある（Bonner & Reinders, 2018; Santos et al., 2016）。読者の言語教育におけるAR・VRの使用法に関する詳細な理解を深めるために、まずこの分野の研究と実践の基本的な概念を概説する。また、AR及びVRアプリケーションについて詳しく説明した上で、このアプリケーションを言語学習に使用する方法について説明する。

Adding virtual information that is indistinguishable from reality has been a long-awaited goal in Augmented Reality (AR). While already demonstrated in the 1960s, only recently have Optical See-Through Head-Mounted Displays (OST-HMDs) seen a reemergence, partially thanks to large investments from industry, and are now considered to be the ultimate hardware for augmenting our visual perception. In this article, we provide a thorough review of state-of-the-art OST-HMD-related techniques that are relevant to realize the aim of an AR interface almost indistinguishable from reality. In this work, we have an initial look at human perception to define requirements and goals for implementing such an interface. We follow up by identifying three key challenges for building an OST-HMD-based AR interface that is indistinguishable from reality: spatial realism, temporal realism, and visual realism. We discuss existing works that aim to overcome these challenges while also reflecting against the goal set by human perception. Finally, we give an outlook into promising research directions and expectations for the years to come.
