This study explores an innovative approach to enhance learning and accelerate comprehension among mining engineering students through the integration of virtual reality (VR) technologies alongside traditional teaching methods. It aims to enhance students' skills through VR applications and improve their understanding of subjects using visual aids. Therefore, this study intends to provide comprehensive knowledge about the operational principles of drill rigs, load-haul-dumps (LHD), and cart transportation systems in mines within field conditions simulated in a VR environment. The simulation includes the use of a VR headset, which immerses the users in the virtual environment and allows them to interact through information boxes. Visual models of the roadways, support, production area, transportation, and production systems of a virtual underground mine were designed using the Unity game engine for the user to navigate a sample mining area with the help of a VR headset. An application was conducted to measure the usability of the VR mine. According to the results of the questionnaire in this application, it shows that most of the participants rated the benefits of the VR training developed as 4.5 or above out of 5 points, while a small number of participants encountered difficulties in using the VR training, resulting in a score of 3.40 out of 5 points.

With the advancement of technology, the virtual reality (VR) industry is expanding rapidly. However, cybersickness continues to be a major concern. Therefore, the aim of this study is to develop a visualisation tool that comprehensively considers hardware, software, and user factors that can affect the VR experience, taking into account both objective and subjective measurements. To accomplish this, we primarily refer to the technical guidelines established by the IEEE std 3079 & TRADE;-2020, which focus on resolving VR sickness due to Head Mounted Display (HMD). Hardware and user factors are measured using tools developed in previous studies, while content factors are developed and integrated into the present study. Content evaluation tools are developed using the Delphi and Analytic Hierarchy Process (AHP) methods, which involve the opinions of 20 experts and weigh content cybersickness-causing factors based on four steps. Along with content evaluation tools, a visualisation tool is developed by combining hardware and user factor evaluation tools. The visualisation tool evaluates VR content based on the perceived excitement level (x-axis) and the sickness level (y-axis) in 16 categories.

Spatial design greatly influences fire evacuation in buildings. Although existing works have comprehensively assessed building spatial design in terms of building circulation, they overlooked how the building layout and emergency signage system affect occupants' attention allocation during fire emergencies. Therefore, this paper proposes a framework to investigate the effectiveness of building evacuation impacted by building spatial design by integrating building information model (BIM), fire simulation, and virtual reality (VR) technology. A case study was carried out to evaluate building spatial design in terms of building circulation and emergency signage. The results demonstrated that when the signage sizes were relatively small but the spacing and placement heights were reasonable, participants were able to recognize and follow the guide. However, insufficient continuity caused the participants to waste much effort searching for helpful information on evacuation-irrelevant objects, reducing fire evacuation efficiency. Moreover, the signage placed at a higher position has a positive effect on route choice.

With the increasing importance of indoor environment to people's quality of life, rational use of indoor thermal energy resources has become a key direction to improve space comfort and energy efficiency. This study aims to explore how indoor thermal energy resources can be effectively integrated into digital image super-resolution reconstruction to improve the performance and user experience of virtual reality space design. The present situation of utilization of thermal energy resources in interior building design and its influence on environmental comfort were studied and analyzed. Then, a digital image super-resolution reconstruction method based on thermal energy resource data is proposed. By collecting indoor thermal energy data such as temperature and humidity, combined with machine learning algorithm, visual quality and realism of virtual reality environment are improved. In this paper, deep learning model is used for image super-resolution reconstruction, and indoor heat resources are introduced as auxiliary information to enhance the detail richness and spatial expressiveness of the reconstructed images. The experimental results show that the reconstruction method using thermal energy resources can significantly improve the image clarity and realism compared with the traditional model. The combination of indoor thermal energy resources and digital image super-resolution reconstruction can not only optimize the design effect of virtual reality space, but also provide new ideas for green building and sustainable development.

Generative Artificial Intelligence (AI) models can propose solutions to scientific problems beyond human capability. To truly make conceptual contributions, researchers need to be capable of understanding the AI-generated structures and extracting the underlying concepts and ideas. When algorithms provide little explanatory reasoning alongside the output, scientists have to reverse-engineer the fundamental insights behind proposals based solely on examples. This task can be challenging as the output is often highly complex and thus not immediately accessible to humans. In this work we show how transferring part of the analysis process into an immersive virtual reality (VR) environment can assist researchers in developing an understanding of AI-generated solutions. We demonstrate the usefulness of VR in finding interpretable configurations of abstract graphs, representing Quantum Optics experiments. Thereby, we can manually discover new generalizations of AI-discoveries as well as new understanding in experimental quantum optics. Furthermore, it allows us to customize the search space in an informed way-as a human-in-the-loop-to achieve significantly faster subsequent discovery iterations. As concrete examples, with this technology, we discover a new resource-efficient 3-dimensional entanglement swapping scheme, as well as a 3-dimensional 4-particle Greenberger-Horne-Zeilinger-state analyzer. Our results show the potential of VR to enhance a researcher's ability to derive knowledge from graph-based generative AI. This type of AI is a widely used abstract data representation in various scientific fields.

This paper addresses the challenge of integrating optimized design solutions in Site Layout Planning (SLP) through virtual reality (VR), questioning how VR simulations can enhance their acceptance. The methodology involves a multi-objective optimization model that evaluates critical factors like earthwork volume, cost, and environmental impact, integrated into a VR framework for interactive participant evaluations. Results show a notable 48.3% increase in decision-making accuracy among participants using VR, highlighting VR's potential to significantly improve comprehension and application of complex data-driven designs in SLP. This underlines the transformative impact of VR on enhancing stakeholder engagement and optimizing design outcomes. Future research will broaden the participant base and further investigate the long-term effects of VR integration in professional environments.

Unsafe behaviour in the workplace and disaster events can lead to serious harm and damage. Safety training has been a widely studied topic over the past two decades. Its primary aim is to save lives and minimise damage but requires regular refreshers. New digital technologies are helping in the process of enhancing safety training for better knowledge acquisition and retention. Among them, virtual reality (VR) can provide an engaging and exciting training experience, and there is a need to evaluate its application and effectiveness in safety *** study aims to investigate VR safety training solutions applied to various industries (excluding medical and military applications), such as construction, fire, aviation, and mining. This was achieved by systematically reviewing 52 articles published between 2013 and 2021 to answer nine research questions. Fourteen domains were examined, with construction and fire safety training being the most prevalent since 2018. Findings reveal that only a small percentage (9.6 %) of the studies explicitly adopted theories while developing and testing VR applications. Additionally, this review highlights a critical need for long-term retention measurements, as only 36 % of studies provided such data. Finally, the two meta-analyses proposed in this work demonstrate that VR safety training outperforms traditional training in terms of knowledge acquisition and retention.

We present virtual reality Self Co-embodiment, a new method for post-stroke upper limb rehabilitation. It is inspired by mirror therapy, where the patient's healthy arm is involved in recovering the affected arm's motion. By tracking the user's head, wrists, and fingers' positions, our new approach allows the handicapped arm to control a digital avatar in order to pursue a reaching task. We apply the concept of virtual co-embodiment to use the information from the unaffected arm and complete the affected limb's impaired motion, which is our added unique feature. This requires users to mechanically involve the incapacitated area as much as possible, prioritizing actual movement rather than the sole imagination of it. As a result, subjects will see a seemingly normally functional virtual arm primarily controlled by their handicapped extremity, but with the constant support of their healthy limb's motion. Our experiment compares the task execution performance and embodiment perceived when interacting with both mirror therapy and our proposed technique. We found that our approach's provided sense of ownership is mildly impacted by users' motion planning response times, which mirror therapy does not exhibit. We also observed that mirror therapy's sense of ownership is moderately affected by the subject's proficiency while executing the assigned task, which our new method did not display. The results indicate that our proposed method provides similar embodiment and rehabilitation capabilities to those perceived from existing mirror therapy. This experiment was performed in healthy individuals to have an unbiased comparison of how mirror therapy's and VRSelfCo's task performance and degree of virtual embodiment compare, but future work explores the possibility of applying this new approach to actual post-stroke patients.

Molecular biology is a complex, abstract, subject that can be challenging for higher education students to comprehend. The current manuscript describes the design, implementation, and evaluation of two immersive VR simulations of a DNA lab and a crime scene investigation (CSI) for a forensic molecular biology course in the context of the "TESLA" Erasmus+ project. It illustrates the instructional design and technical aspects of the VR simulations' development. The experimental study employed a comparative quantitative research design. The guiding research questions examined how instructional modalities (online vs. face-to-face) affect learners' perceptions of VR-based training in higher education and the key factors influencing learners' intention for their adoption. Forty-six (n = 46) undergraduate students completed a 17-item questionnaire, which served as the main data collection instrument. Results demonstrate that both online and face-to-face VR-based instruction can effectively convey core concepts, thus challenging the traditional notion that face-to-face interaction is inherently superior. Its implications underscore the potential of VR simulations to supplement or even substitute traditional teaching methods, particularly for complex science subjects.

Although mathematical literacy skills have been emphasized in education, standardized test results show that students still struggle in this regard. Hypothesizing that both virtual and realistic mathematics education approaches may be useful, this article combines two approaches as virtual Realistic Mathematics Education (VRME) to enhance mathematical literacy. A one-group experimental research design was adopted with the participation of 20 6th-grade middle school students. The qualitative data were also used to explain the improvements in mathematical literacy. The results revealed that all of the dimensions of mathematical literacy skills;employ, interpret and formulate were improved while the improvements in interpret dimension was the lowest. The results also indicated the importance of knowledge co-construction through discussion for the development of mathematical literacy, especially for the interpret dimension. Finally, the study demonstrated that virtual tools can be used to improve mathematical literacy by expanding RME.
