Immersive engineering instruction: Using Virtual Reality to enhance students’ experience in the classroom

Extended-Reality Technologies: An Overview of Emerging Applications in Medical Education and Clinical Care.

In order to improve the efficiency of information acquisition and task selection in Virtual Reality (VR) systems, enhance the interactive experience, and reduce cognitive load for users, it is crucial to effectively organize and leverage user cognitive psychology and design elements during the VR scene design phase. This paper focuses on analyzing the low cognitive load requirements of users and the need for a satisfactory user perceptual experience based on the cognitive resource theory. We propose a method for optimizing the design of VR system scenario tasks under low cognitive load requirements. By utilizing human-computer hybrid intelligent assistance for predicting user cognitive load and incorporating intelligent optimization genetic algorithms into the optimization of VR system design elements, we aim to minimize cognitive load as the objective function based on the principle of low cognitive load. Important knowledge granularity nodes are used as fitness functions in the optimization process of VR system design resource elements. An application study is conducted, combining the multi-channel cognition in a smart city VR system task information interface, to optimize the system resource features. The study validates and compares the solutions obtained through traditional design processes and the solutions optimized by the method proposed in this paper, using virtual reality eye-tracking experiments for the same design task requirements in VR systems. The results demonstrate that users experience lower cognitive load and better task operation experience when interacting with the optimized solutions proposed in this paper. Therefore, the optimization method studied in this paper can serve as a reference for the construction of virtual reality systems.

This paper describes a study aimed at developing and applying a method for comparing the user experience (UX) of virtual reality (VR) systems, in order to identify aspects that differentiate VR systems from a user perspective as well as aspects that users consider important when selecting a VR system. A within-subjects study was conducted, in which twelve participants played a VR game using four different VR systems (i.e., VR headsets and hand controllers). The UX was evaluated through semi-structured interviews and questionnaires. Headset comfort, fit, and perceived image quality as well as unrestricted mobility (i.e., untethered headsets) were identified as important aspects for the UX. Hand controllers that allowed more natural interaction were generally preferred. Image sharpness and headset comfort were considered the most important aspects for selecting a VR system. The study demonstrated that the method can be applied and generate insights into the UX of VR systems.

The integration of virtual reality (VR) and the metaverse into education, particularly competency-based fields such as medical science education, has introduced a transformative approach to teaching and learning. Traditional medical training often faces challenges such as resource limitations, ethical concerns, and restricted access to specialized facilities. VR and metaverse technologies address these issues by providing immersive, interactive, and scalable learning environments that enhance both conceptual understanding and practical skills. This chapter explores the applications of VR in medical laboratories, surgical training, patient treatment, and interdisciplinary education, highlighting its impact on engagement, skill acquisition, and knowledge retention. An empirical study on VR-based polymerase chain reaction (PCR) training is presented, demonstrating its effectiveness in laboratory instruction. Findings reveal that while VR significantly benefits novice learners by increasing confidence and comprehension, expert users may require more advanced features, such as haptic feedback, to maintain engagement. The discussion also addresses challenges such as cognitive load, usability, and accessibility, emphasizing the need for further refinement and institutional support. As technology continues to evolve, the metaverse holds immense potential to revolutionize medical education by making high-quality training more accessible, adaptable, and interactive, ultimately shaping the future of healthcare education and professional development.

Virtual Reality (VR) technology has emerged as a promising tool to revolutionize skill-based training programs by providing immersive and interactive learning environments. This study explores the impact of VR on enhancing training effectiveness within Vietnam’s workforce development initiatives. Through a mixed-methods approach combining quantitative performance data and qualitative feedback from 300 trainees across manufacturing, healthcare, and vocational education sectors, the research evaluates VR’s role in improving skill acquisition, learner engagement, and retention compared to traditional training methods. The findings indicate that VR-based training significantly increases post-training proficiency scores by an average of 25%, while reducing the time required to achieve competency by approximately 30%. In manufacturing, VR simulations enable trainees to safely practice assembly line operations and error management, resulting in fewer workplace mistakes. In healthcare, VR modules focused on surgical and procedural training improve procedural confidence and adherence to clinical protocols. User surveys reveal high satisfaction levels, particularly appreciating the realistic, risk-free practice environment. However, challenges such as high initial investment costs, limited localized VR content, and technical infrastructure gaps—especially in rural areas—limit widespread adoption. Addressing these barriers requires targeted strategies including content localization, government support, and infrastructure development. This study underscores VR’s potential to enhance skill-based training effectiveness and accelerate workforce readiness in emerging economies like Vietnam. It provides critical insights for policymakers, educators, and industry leaders aiming to integrate advanced technologies into training programs to meet evolving labor market demands.

Low latency is a fundamental requirement for Virtual Reality (VR) systems to reduce the potential risks of cybersickness and to increase effectiveness, efficiency and user experience. In contrast to the effects of uniform latency degradation, the influence of latency jitter on user experience in VR is not well researched, although today's consumer VR systems are vulnerable in this respect. In this work we report on the impact of latency jitter on cybersickness in HMD-based VR environments. Test subjects are given a search task in Virtual Reality, provoking both head rotation and translation. One group experienced artificially added latency jitter in the tracking data of their head-mounted display. The introduced jitter pattern was a replication of a real-world latency behavior extracted and analyzed from an existing example VR-system. The effects of the introduced latency jitter were measured based on self-reports simulator sickness questionnaire (SSQ) and by taking physiological measurements. We found a significant increase in self-reported simulator sickness. We therefore argue that measure and control of latency based on average values taken at a few time intervals is not enough to assure a required timeliness behavior but that latency jitter needs to be considered when designing experiences for Virtual Reality.

The Reality of Virtual Reality in Echocardiography Education?

Leveraging virtual reality for advanced scrub nurse education: A non-randomized comparative study of training effectiveness

Background and Purpose: Repetitive practice improves function and facilitates cortical plasticity after stroke. Virtual reality (VR) systems have the potential to provide motivating and safe repetitive practice with minimal supervision. The purpose of this case study is to look at the effect of a VR system, activated by surface electromyography of dorsiflexors and plantarflexors, on gait velocity, function, and kinematics. Method: The first person randomized to the treatment group of a larger study was chosen for this case. She was 51 years old and 9 months poststroke. She received treatment 3 times per week for 8 weeks. Each 60-minute session consisted of both structured lower extremity exercise and VR ankle activities. Results: After intervention, the subject demonstrated increased gait speed and decreased time to perform the modified Emory Functional Ambulation Profile. Gait kinematics demonstrated improved ankle motion and plantarflexion moments at push off. Discussion: The improved gait speed, possibly due to increased ankle plantarflexion motion and moments, resulted in a more normalized trailing limb posture. This case study suggests that ankle to computer VR systems may help stroke patients improve gait function. This VR system has potential as an adjunctive therapy or home program requiring minimal supervision.

PurposeEmerging technologies, such as virtual reality (VR), have been influencing both the tourism supply side and tourists alike. The purpose of this study is to analyse VR research in tourism and to provide a comprehensive state-of-the-art review. As the technological connotation of the term VR has been changing and encompasses various VR systems with different capabilities, this paper aims to provide a systematic and structured overview. The overall objective of this paper is to contribute to a thorough understanding of VR research in tourism.Design/methodology/approachThis paper comprehensively reviews and analyses existing literature on VR in tourism, published from 1994 to February 2018. Using a wide variety of sources, these papers were examined so as to give a state-of-the-art literature review and to deepen one’s understanding of the diverse applications of VR in a tourism context. This paper also presents a novel classification of different VR systems according to the level of immersion and depicts their respective technological capabilities.FindingsThe advent of new VR hardware necessitates a distinction for different VR systems applied in the tourism sector. Research conducted during the past three years has been focussing on the application of head-mounted displays, which reflects the temporal development of VR technology. Regardless of the VR system, most studies examine VR as a marketing tool for promotion and communication purposes during the pre-travel phase, focussing on behavioural aspects. Advances in technology will yield new opportunities and application possibilities for the tourism industry.Originality/valueThe key contribution of this paper lies in its structural approach, which differentiates between non-, semi- and fully immersive VR systems in tourism, as well as the proposition of respective definitions. The concluding part of the paper proposes practical implications for tourism businesses together with directions for future studies.

Virtual reality (VR) technology is commonly used in entertainment applications; however, it has also been deployed in practical applications in more serious aspects of our lives, such as safety. To support people working in dangerous industries, VR can ensure operators manipulate standardized tasks and work collaboratively to deal with potential risks. Surprisingly, little research has focused on how people can collaboratively work in VR environments. Few studies have paid attention to the cognitive load of operators in their collaborative tasks. Once task demands become complex, many researchers focus on optimizing the design of the interaction interfaces to reduce the cognitive load on the operator. That approach could be of merit; however, it can actually subject operators to a more significant cognitive load and potentially more errors and a failure of collaboration. In this paper, we propose a new collaborative VR system to support two teleoperators working in the VR environment to remote control an uncrewed ground vehicle. We use a compared experiment to evaluate the collaborative VR systems, focusing on the time spent on tasks and the total number of operations. Our results show that the total number of processes and the cognitive load during operations were significantly lower in the two-person group than in the single-person group. Our study sheds light on designing VR systems to support collaborative work with respect to the flow of work of teleoperators instead of simply optimizing the design outcomes.

Lower body tracking and user experience analysis are ongoing challenges in immersive technologies and biomechanics research, respectively. Particularly, in immersive technologies like mixed reality, there are limited research applications in user comfort and experience, and locomotion. In this paper, we aimed to conduct a cross-disciplinary research (by combining the elements of Biomechanics and human–computer interaction) in understanding the impact of user experience and immersive technologies induced symptoms in virtual and mixed reality environments for obstacle clearance tasks. For this, we created obstacle clearance applications for Oculus Quest and Microsoft HoloLens. Also, we conducted a user study with 12 participants under two conditions (virtual reality and mixed reality) in obstacle clearance behavior of varying heights. The results from our study indicated that the levels of immersion and enjoyment were significantly higher in virtual reality compared to mixed reality. In terms of virtual reality-induced symptoms, the participants found the mixed reality environment to be slightly more comfortable than virtual reality.

The fast growth of virtual reality (VR) and augmented reality (AR) head-mounted displays provides a new medium for interactive visualisations and visual analytics. Presence is the experience of consciousness within extended reality, and it has the potential to increase task performance. This project studies the impact that a sense of presence has on data visualisation performance and user experience under AR and VR conditions. A within-subjects design recruited 38 participants to complete interactive visualisation tasks within the novel immersive data analytics system for genomic data in AR and VR, and measured speed, accuracy, preference, presence, and user satisfaction. Open-ended user experience responses were also collected. The results implied that VR was more conducive to efficiency, effectiveness, and user experience as well as offering insight into possible cognitive load benefits for VR users.

With the rapid development of science and technology, virtual reality (VR) systems have developed rapidly. VR systems can be applied in many fields such as education, medical, military, and probing. According to the survey, the VR system will have a delay in the process of acquisition, transmission and processing, and more than 40% of the human body will have motion sickness after experiencing VR. The cause of motion sickness is delay. Accurate measurement of delays therefore helps to resolve motion sickness in the virtual world and provides guidance for the upgrade of these systems. In response to the existing problems, our research team designed a low-cost, high-performance experimental equipment that uses a single-chip microcomputer and a PIN photodiode as the hardware core of the delay detection device. The light intensity changes are used to determine the start and end of the detection. The algorithm calculates the delay time of the VR device.

The author investigated the interaction effect of immersive virtual reality (VR) in the classroom. The objective of the project was to develop and provide a low-cost, scalable, and portable VR system containing purposely designed and developed immersive virtual learning environments for the US Army. The purpose of the mixed design experiment was to compare lecture-based and immersive VR-based multimedia instruction, in terms of declarative knowledge acquisition (i.e. learning) of basic corrosion prevention and control with military personnel. Participants were randomly assigned to the control group (N = 115) or investigational group (N = 25) and tested immediately before and after training. The author accessed learning outcomes from the pre-exam and post-exam scores and VR system usability from exit questionnaires. Results indicate that both forms of instruction will increase learning. VR-based did produce higher gain scores and there was a statistically significant interaction between instruction type and time.
