Using virtual and augmented reality to study architectural lighting

This paper presents industry stakeholder insights from the implementation of a dual modality intervention using virtual and augmented reality simulation to study complex lighting theory in architecture design. Using a design based research method the aim is to evaluate these insights and inform a pilot study to educate first year architectural design students on the complexities of lighting the built environment and methods to improve architectural workflow. The aim is to enable learners to experience natural and artificial lighting methods comparatively in real-time through multiple comparative visualisation methods. This is important to make informed evaluations regarding architectural designs in terms of spatial quality, character, performance, and user-comfort levels. This in turn allows architects to rapidly modify their designs to accommodate or mitigate the environmental effects. Outcomes from the initial usability test highlight the ability to switch back and forth between the virtual and augmented reality simulation technology, and between lighting visualisation modes as a huge step forward by the industry stakeholders. Additionally, the idea of representing the physical building where the simulation took place virtually using a detailed mapping gave a real-world anchor that made the simulations easy to navigate, leading to improved satisfaction and engagement. However, the study also highlighted improvements in the delivery of the simulation is required to improve simulation learnability and efficiency.

Application of virtual reality and haptics system Simodont in Chinese dental education: A scoping review.

Virtual reality (VR) and haptic simulation technology have been increasingly implemented in dental training. Since the first haptic VR dental simulator (Simodont) was introduced 10 years ago, it has been applied in more than 40 universities in mainland China. This scoping review aimed to review literature, showcasing the teaching reform of dental virtual simulation in mainland China to global dental education peers. This scoping review was conducted using the PRISMA extension for scoping review guidelines. Seven electronic databases were searched, and two reviewers independently performed the selection and characterization of the studies. The final scoping review included 12 studies. Four studies focused on the G. V. Black class II cavity, three on manual dexterity skills training, two on full metal crown preparation, one on pulpal access and coronal cavity preparation, one on flipped classroom teaching, and one on 'doctor-patient communication' skills. The most critical scenarios, self-assessment, working posture, curriculum setting, training and cost are analysed and discussed. Haptic simulation technology is a valuable complementary tool to the phantom head in dental education. The combined utilization of these two training devices has been superior to either in isolation. However, there is a lack of research on the sequencing of the two systems, as well as the appropriate distribution of curriculum between them. It is necessary for educators to organize or engage in experience sharing, collaboration and knowledge dissemination. These actions are essential for promoting effective teaching within dental educational institutions.

Teaching Practices of a Warehousing Management Curriculum based on Virtual Reality Simulation Technology

&#x0D; Warehousing management is a specialized core curriculum in the logistics management major. The curriculum not only teaches strong theoretical concepts, but also practical skills. Traditional teaching mode emphasizes on theoretical teaching due to the lack of sufficient practical conditions; hence, students’ practical abilities cannot be developed comprehensively. Therefore, this study proposed teaching reform measures, such as reconstructing the curriculum content, implementing modularized teaching, and creating a build-task-exercise-evaluation teaching mode by introducing virtual reality (VR) simulation technology and improving the teaching method. With these measures, students could finish their tasks and realize their learning objectives in the virtual intelligent warehouse environment by combining the knowledge and skills they have learned. Moreover, students were asked to design a warehouse layout by using the simulation software according to enterprise case data. Results show that the task-driven teaching reform for warehousing management curriculum based on VR technology improves the efficiency and quality of students’ skill training.&#x0D;

Virtual Reality Simulation for Disaster Preparedness Training in Hospitals: Integrated Review.

BackgroundA critical component of disaster preparedness in hospitals is experiential education and training of health care professionals. A live drill is a well-established, effective training approach, but cost restraints and logistic constraints make clinical implementation challenging, and training opportunities with live drills may be severely limited. Virtual reality simulation (VRS) technology may offer a viable training alternative with its inherent features of reproducibility, just-in-time training, and repeatability.ObjectiveThis integrated review examines the scientific evidence pertaining to the effectiveness of VRS and its practical usefulness in training health care professionals for in-hospital disaster preparedness.MethodsA well-known 4-stage methodology was used for the integrated review process. It consisted of problem identification, a literature search and inclusion criteria determination, 2-stage validation and analysis of searched studies, and presentation of findings. A search of diverse publication repositories was performed. They included Web of Science (WOS), PubMed (PMD), and Embase (EMB).ResultsThe integrated review process resulted in 12 studies being included. Principle findings identified 3 major capabilities of VRS: (1) to realistically simulate the clinical environment and medical practices related to different disaster scenarios, (2) to develop learning effects on increased confidence and enhanced knowledge acquisition, and (3) to enable cost-effective implementation of training programs.ConclusionsThe findings from the integrated review suggested that VRS could be a competitive, cost-effective adjunct to existing training approaches. Although the findings demonstrated the applicability of VRS to different training scenarios, these do not entirely cover all disaster scenarios that could happen in hospitals. This integrated review expects that the recent advances of VR technologies can be 1 of the catalysts to enable the wider adoption of VRS training on challenging clinical scenarios that require sophisticated modeling and environment depiction.

Virtual Prototyping: Evaluating the Digital Twin Based Virtual Factory for New Product Introduction

Shortening lifecycles and increasing complexity make product and production lifecycle processes more challenging than ever for manufacturing enterprises. Virtual Prototyping (VP) technologies promise a viable solution to handle such challenges in reducing time and physical builds as well as increasing quality. In previous studies, the Digital Twin (DT) based Virtual Factory (VF) concept showed significant potential to handle co-evolution by integrating 3D factory and product models with immersive and interactive 3D Virtual Reality (VR) simulation technology as well as real-time bidirectional data synchronisation between virtual and physical production systems. In this article, we present an extension to the paper “Demonstrating and Evaluating the Digital Twin Based Virtual Factory for Virtual Prototyping” presented at CARV2021. The study presents an evaluation by industry experts of the DT based VF concept for VP in the context of New Product Introduction (NPI) processes. The concept is demonstrated in two cases: wind turbine blade manufacturing and nacelle assembly operations at Vestas Wind Systems A/S. The study shows that the VF provides an immersive virtual environment, which allows the users to reduce the time needed for prototyping. The industry experts propose several business cases for the introduced solution and find that the phases that would have the most gain are the later ones (production) where the product design is more mature.

Past, present, and future of surgical simulation and perspective of a developing country: A narrative review.

Healthcare systems around the globe have been revolutionised in the last few decades, resulting in a greater need and demand for surgical education outside the operation theatres. Surgical education through simulations started around 2,500 years ago when they were first used in the planning of unique and innovative surgeries while ensuring the safety of the subjects. Currently, simulations include animal models, cadaveric models, benchtop models and complex robotic models. In a programme involving surgical simulators, four requirements are followed to optimise their effectiveness, including mandatory involvement, skill-based instruction, standardised training plan, and overtraining. We can make a reasonable estimation that the future is technology-based. The speed with which we anticipate the fusion of these virtual reality and robotics-based simulation technology with medical educations and practices largely depends on the affordability and economics of these tools. The current narrative review was planned to highlight the historical aspects of simulations, their role in surgical education, and their importance in the future as an essential adjunct to surgical education.

Application of Wireless Virtual Reality Perception and Simulation Technology in Film and Television Animation

Wireless virtual reality integrated multidisciplinary technology, combined with related industries and fields, has changed the way of human-computer interaction and opened up a new field of user experience. In recent years, with the rapid improvement of computer technology and hardware conditions, interactive technology has developed rapidly. The existing wireless virtual reality interactive system is too single and cannot be used in multiple environments. The original system requires a large number of sensor equipment, the cost is high, and the traditional perception technology is too restrictive and cannot realize human-computer interaction more naturally. This paper proposes a dual intention perception algorithm based on the fusion of touch (obtained by experimental simulation equipment), hearing, and vision. The algorithm can perceive the user’s operation intention through the user’s natural behavior and can identify the user’s two intentions at the same time. This paper proposes a navigational interactive mode, which provides users with multimodal intelligent navigation through intelligent perception of user intent and experimental progress. We determine the impact model of the interactive system effect evaluation and analyze its effect evaluation strategy in depth and then further quantify the indicators under the four effect dimensions of information perception, artistic reflection, social entertainment, and aesthetic experience. A combination of qualitative and quantitative methods was used to carry out relevant research on effect evaluation, usability test, and questionnaire interview. The experimental results show that this interactive system has better entertainment effects than other forms of film and television animation, but still needs to pay attention to and strengthen the construction and embodiment of film and television animation content, as well as the optimization and perfection of the fault-tolerant mechanism in the design process.

Virtual Reality Technology and Simulation Technology to Development of Smart Travelling in the Time of Industrial Revolution 4.0

The push of levers of digital boom technology in the era of industrial revolution 4.0 has created great impetus for economic development, especially in maintaining and revitalizing the smokeless tourism industry. That makes even more sense in the context of the current covid 19 pandemic and increasing social distancing. It can be said that the appearance of the COVID-19 epidemic has adversely affected the economy, fundamentally changing people's living and consumption behavior. Meanwhile, business sectors are facing the risk of production shutdown because of capital flow downturn, idle operation or bankruptcy because of covid19. The reason for social distancing forces people to not be able to travel freely to carry out travel and shopping behaviors like before. Previously normal activities were restricted from being concentrated in large places, leading to a business industry that was supposed to be super-profitable and a major contributor to a high GDP structure such as tourism, which is facing a dilemma. The tourist season is coming, but the number of tourists suddenly drops because of social distancing. That risk poses a big obstacle to the tourism industry, but it will be an opportunity if we know how to take advantage of the 4.0 technology revolution. That will help make use of smart digital technology applications to exploit and develop different types of tourism. Research and propose ideas to apply VR technology to develop smart tourism industry, helping tourists from all over the world can use and experience famous tourist attractions of Vietnam. VR virtual reality technology allows to maintain and develop tourism activities in the context of the current pandemic.

Is clinical virtual reality ready for primetime?

Since the mid-1990s, a significant scientific literature has evolved regarding the outcomes from the use of what we now refer to as clinical virtual reality (VR). This use of VR simulation technology has produced encouraging results when applied to address cognitive, psychological, motor, and functional impairments across a wide range of clinical health conditions. This article addresses the question, "Is clinical VR ready for primetime?" After a brief description of the various forms of VR technology, we discuss the trajectory of clinical VR over the last 20 years and summarize the basic assets that VR offers for creating clinical applications. The discussion then addresses the question of readiness in terms of the theoretical basis for clinical VR assets, the research to date, the pragmatic factors regarding availability, usability, and costs of clinical VR content/systems, and the ethical issues for the safe use of VR with clinical populations. Our review of the theoretical underpinnings and research findings to date leads to the prediction that clinical VR will have a significant impact on future research and practice. Pragmatic issues that can influence adoption across many areas of psychology also appear favorable, but professional guidelines will be needed to promote its safe and ethical use. Although there is still much research needed to advance the science in this area, we strongly believe that clinical VR applications will become indispensable tools in the toolbox of psychological researchers and practitioners and will only grow in relevance and popularity in the future.

Simulation and curriculum design: a global survey in dental education.

Curriculum reforms are being driven by globalization and international standardization. Although new information technologies such as dental haptic virtual reality (VR) simulation systems have provided potential new possibilities for clinical learning in dental curricula, infusion into curricula requires careful planning. This study aimed to identify current patterns in the role and integration of simulation in dental degree curricula internationally. An original internet survey was distributed by invitation to clinical curriculum leaders in dental schools in Asia, Europe, North America, and Oceania (Australia and New Zealand). The results (N=62) showed Asia, Europe and Oceania tended towards integrated curriculum designs with North America having a higher proportion of traditional curricula. North America had limited implementation of haptic VR simulation technology but reported the highest number of scheduled simulation hours. Australia and New Zealand were the most likely regions to incorporate haptic VR simulation technology. This survey indicated considerable variation in curriculum structure with regionally-specific preferences being evident in terms of curriculum structure, teaching philosophies and motivation for incorporation of VR haptic simulation into curricula. This study illustrates the need for an improved evidence base on dental simulations to inform curriculum designs and psychomotor skill learning in dentistry.
