Stereoscopic objects affect reaching performance in virtual reality environments: influence of age on motor control

Although the stereoscopic effect in 3D virtual reality (VR) space has been studied, its influence on motor performance, specifically how stereoscopic objects affect behavioral outcomes like reaching, remains unclear. Previous research has primarily focused on perceptual aspects rather than on how stereoscopic visual input impacts motor control at the behavioral level. Thus, we investigated the effects of stereoscopic objects in a VR environment on reaching performance, examining whether the stereoscopic effect of objects is a significant aspect enough to affect performance at the behavioral level. While doing so, we investigated young and older adults separately, as age is a critical factor influencing motor performance. Fourteen young and 23 older participants performed a reaching task in the VR space. The target objects were 2D and 3D, deviating from the initial position by 10 and 20 cm. The movement attributed to feedforward control was analyzed using end-point error and smoothness of movement. Our results revealed that older participants had significantly worse predictive control than young participants in the 3D long task, suggesting that the positions of 3D objects were more difficult to predict than those of 2D objects. Young participants showed a significant difference in smoothness between 2D and 3D objects, which was not observed in older participants. This may reflect the floor effect in older participants. Under the short-distance condition, neither group showed a significant difference, suggesting the ceiling effect by distance. We confirmed that the effect of stereoscopic objects was not drastic but it did hamper the reaching performance.

Transforming the Patient-Provider Relationship Through Digitalized Peer Support in Japan

ABSTRACT The recent explosion in online dissemination of health-related information, and its availability to more and more people around the world, has led to a situation in which both healthcare providers and patients are accepting new roles. This paper examines the transformations toward new roles for healthcare professionals and patients, with a focus on Japan, based on the assumption that one of the driving forces accelerating these changes may be the digitalization of patient peer support. The methods used in this study were: 1) questionnaires and interviews with patients and healthcare providers asking about their participation in peer support and the effectiveness of its implementation; and 2) observations, questionnaires, and interviews with three patient groups about the experience of digitalizing peer support (via implementation of peer support in a virtual reality space). Analysis of the data showed that peer support by patient groups has both challenges and benefits, and that peer support in virtual spaces has certain positive effects. The empowerment of patients through digitalized peer support is transforming the relationship between healthcare providers and patients, changing it from a traditional asymmetrical relationship (in which the healthcare professionals are in a dominant position) to a cooperative relationship on a more equal footing.

A virtually-induced overview effect? How seeing the world from above through a simulated space tour is related to awe, global identity and pro-environmental behaviour

Global environmental crises require concerted action around the globe. Previous research has suggested that salient global identity (i.e. identification with and concern for people all over the world) might motivate such action, as it is positively related to pro-environmental behaviour. However, little is known about how to strengthen global identity. Inferred from astronauts' experiences when seeing our planet from space (i.e. the overview effect), we hypothesised that a virtual reality (VR) space tour elicits awe (i.e. an experience of extraordinary vastness associated with feeling moved, amazed and overwhelmed), makes global identity more salient and motivates pro-environmental behaviour. We compared the effect of the VR simulation to that of music, a stimulus unrelated to nature. In a preregistered laboratory experiment, participants of a convenience sample in Germany (N = 128) were randomly assigned to four groups, using a 2 (VR: yes vs. no) × 2 (music: yes vs. no) design, and answered a self-report questionnaire. We found that both the VR space tour and music elicited awe, but that the effects of VR were stronger. We found neither significant main nor interaction effects of VR and music on global identity. However, both the VR simulation and music indirectly predicted stronger global self-investment (i.e. one dimension of global identity reflecting solidarity and concern for people world-wide) through a stronger awe experience. Neither the VR simulation nor music impacted people's pro-environmental behaviour in terms of their willingness to sign a petition asking the government to prioritise the Paris climate agreement. However, they both indirectly predicted willingness to sign the petition through a stronger awe experience. We discuss the role of awe for global identity and pro-environmental behaviour, and elaborate on the idea that a greater portion of global identity may be a stable trait rather than a variable state. We also discuss how useful VR simulations are for encouraging pro-environmental behaviour.

SEEG4D: a tool for 4D visualization of stereoelectroencephalography data.

Epilepsy is a prevalent and serious neurological condition which impacts millions of people worldwide. Stereoelectroencephalography (sEEG) is used in cases of drug resistant epilepsy to aid in surgical resection planning due to its high spatial resolution and ability to visualize seizure onset zones. For accurate localization of the seizure focus, sEEG studies combine pre-implantation magnetic resonance imaging, post-implant computed tomography to visualize electrodes, and temporally recorded sEEG electrophysiological data. Many tools exist to assist in merging multimodal spatial information; however, few allow for an integrated spatiotemporal view of the electrical activity. In the current work, we present SEEG4D, an automated tool to merge spatial and temporal data into a complete, four-dimensional virtual reality (VR) object with temporal electrophysiology that enables the simultaneous viewing of anatomy and seizure activity for seizure localization and presurgical planning. We developed an automated, containerized pipeline to segment tissues and electrode contacts. Contacts are aligned with electrical activity and then animated based on relative power. SEEG4D generates models which can be loaded into VR platforms for viewing and planning with the surgical team. Automated contact segmentation locations are within 1 mm of trained raters and models generated show signal propagation along electrodes. Critically, spatial-temporal information communicated through our models in a VR space have potential to enhance sEEG pre-surgical planning.

A virtual-reality spatial matching algorithm and its application on equipment maintenance support: System design and user study

Equipment maintenance support is an important technical measure to maintain the equipment’s expected performance. However, the current maintenance supports are mainly completed by maintainers under the guidance of technical manual or additional experts, which may be insufficient for some advanced equipment with rapid update rate and complex inner structure. The rising technology of augmented reality (AR) provides a new solution for equipment maintenance support, while one of the key issues limiting the practical application of AR in maintenance field is the spatial matching issue between virtual space and reality space. In this paper, a virtual-reality spatial matching algorithm is designed to accurately superimpose the virtual information to the corresponding actual scene on the AR glasses. In this algorithm, two methods are proposed to help achieve the stable matching of virtual space and reality space. In detail, to obtain the saliency map with less background interference and improved saliency detection accuracy, a saliency detection method is designed based on the super-pixel segmentation. To deal with the problems of uneven distribution on the feature points and weak robustness to the light changes, a feature extraction and matching method is proposed for acquiring the feature point matching set with the utilization of the obtained saliency map. Finally, an immersive equipment maintenance support system (IEMSS) is developed based on this spatial matching algorithm, which provides the maintainers with immediate and immersive guidance to improve the efficiency and safety in the maintenance task, as well as offers maintenance training for inexperienced maintainers with expanded virtual information in case of limited experts. Several comparative experiments are implemented to verify the effectiveness of proposed methods, and a user study of real system application is carried out to further evaluate the superiority of these methods when applied in the IEMSS.

블랜디드 러닝 수업을 적용한 칼림바 합주 수업지도 방안 연구: 메타버스 플랫폼 ‘ZEP’을 중심으로

The purpose of this study is to design a Kalimba ensemble teaching plan based on the direction and digital application of the 2022 revised curriculum, and to suggest ways to effectively fulfill the goals of the 2022 revised curriculum in the school setting. The theoretical backgrounds of the Kalimba and the Metaverse were gathered through a review of academic papers and dissertations. The performance domain of the 2022 revised music curriculum was analyzed to design a teaching plan and explore practical methods for implementing a digital-instrument integrated class, as intended by the revised curriculum. The digital elements and music performance classes emphasized in the 2022 revised curriculum were fused so that students could experience the basics of new technologies. To create a student-led participatory class, a virtual reality space and study score were produced directly, enabling students to engage in creative and self-directed learning. To complement this, this study creates a virtual reality space using the Metaverse platform "ZEP" and provides online video and ensemble performance forms using the video link connection function of "ZEP" to foster basic digital literacy and improve music performance. It is hoped that research on instrumental teaching methods using digital media will be further expanded so that students can recognize the sensibility and value of music.

A novel mixed reality remote collaboration system with adaptive generation of instructions

Mixed Reality (MR) remote collaboration supports a shared workspace and various non-verbal communication cues that enable remote experts to express ideas in an immersive Virtual Reality (VR) space to guide local workers in industrial physical tasks by creating Augmented Reality (AR) instructions, such as remote assembly/disassembly guidance, emergency maintenance, and training. However, due to the information non-symmetrical caused by geographical distribution, it can be challenging and high-workload for remote experts to create clear and detailed AR instructions for local workers to match spatial relationships with the local workspace, while comprehensively considering the situation information (e.g., task-related objects and partner’s environment) in complex industrial physical tasks. Advances in ambient intelligence bring ideas for building a new remote collaboration framework that supports the adaptive generation of instructions. In the study, we developed a novel MR remote collaboration prototype system, which can automatically and adaptively generate clear, detailed, and standardized AR instructions based on remote experts’ simple and intuitive interactions and local contextual information to assist remote experts in guiding local workers to complete industrial physical tasks, especially industrial assembly tasks. The effect of two interfaces on industrial assembly tasks involving relatively complex process information and environments was explored in a user study: one was a baseline solution that uses a typical MR remote collaboration interface to support remote experts to create instructions (RECI) using popular non-verbal communication cues in the shared local 3D stereoscopic scene, and the other was our novel interface that additionally supported the adaptive generation of instructions via context awareness (AGICA) on top of the typical interface. The result of the user study showed that AGICA significantly improves collaboration performance, reduces errors and workload, and enhances usability and user experience compared to RECI. This demonstrates that supporting the adaptive generation of instructions is a feasible way to enhance MR remote collaboration in industrial assembly tasks with relatively complex process information and environments. Our research findings have a certain guiding significance for the design of MR remote collaboration systems in such tasks.

What Prevents Us From Learning Virtual Reality Space: A Study of Indoor Corridor Angle and Obstacle Transparency

People sometimes become disorientated and feel unnatural in virtual reality (VR) spaces created via devices such as head-mounted displays. The main problem is that multiple structures make it difficult to learn the VR space, particularly indoors. These structures segment the space and form boundaries for sightlines and activity areas. How obstacles in segmented space affect human behavior have been less discussed in studies related to navigation. This study sought to clarify the mechanism for the effect of spatial segmentation effect on human spatial cognition, in the context of indoor navigation. This study was conducted in a VR scenario with an omni-directional treadmill; a total of 76 college students participated, and 52 of them were included in the analysis. The study found that the cognitive distortion from spatial segmentation primarily operates by activity area rather than visual obstruction, and it can be inferred that the basis of human abstraction of spatial information may perhaps be the activity area. Regardless of obstacle transparency, non-rectangular spatial segmentation deteriorates navigational performance. The results suggest that, future metaverse communities should consider designing rectangular segmented activity areas to improve navigation performance and reduce disorientation.

A real-time virtual outing using virtual reality for a hospitalized terminal cancer patient who has difficulty going out: a case report

Objective: Even if hospitalized terminal cancer patients wish to go out, it is sometimes difficult for them to realize this because of various symptoms. We have been providing a virtual outing experience using virtual reality (VR) for terminal cancer patients who have difficulty going out, and have often received requests to “talk with people in the virtual outing,” but there is a problem that a large time lag occurs in conversation in a VR space under the general Internet environment. However, with the advent of systems that enable high-speed, low-latency communications, real-time communication is now possible even in VR spaces. Thus, we aimed to explore the feasibility of implementing the real-time virtual outing.Methods: The patient’s preferred virtual outing was to his daughter’s new home. The study operator used a 360° video real-time sharing system to broadcast the view of the daughter’s home. The patient experienced the images using a VR head-mounted display in his room. The patient’s wife, son, daughter, and grandson participated in this delivery using a laptop computer from a dayroom in the hospital, and his daughter’s husband participated using the 360° video real-time sharing system from the daughter’s home with the researcher. Before and after the virtual outing, changes in symptoms and emotions were assessed using the Edmonton Symptom Assessment System Revised Japanese version and the Numerical Rating Scale for headache, dizziness, pleasure, and satisfaction. In addition, we collected the patients’ impressions of the virtual outing.Results: The patient was a male in his early 70s. After approximately 30 min of real-time virtual outings, “tiredness, drowsiness, depression, and wellbeing” were improved and “pleasure, and satisfaction” were increased, while no side effects or worsening of symptoms were observed. In addition, it was observed from the patient’s comments that he felt a sense of presence, as if he were her home.Discussion: The patient and his family could enjoy smooth conversation without time lag even in the VR space. Therefore, it was suggested that real-time virtual outings using VR could help realize the wishes of hospitalized terminal cancer patients who have difficulty going out as a new approach.

Analysis of the Rendering of Deep and Short Art Effects Under the Multimedia Background Taking into Account the 3D Ink Rendering Algorithm

People's living standard is improving and the economy is developing rapidly, so the demand for spiritual culture is also increasing. Today, with the rapid development of information technology, 3D ink rendering technology has become an indispensable part of modern art. It is not only a visual expression and tool, but also has a great impact on people's daily life. It is based on computer language and multimedia software. Its main purpose is to express art through images, sound and text; it can also integrate various complex and creative elements to form a whole picture, thus giving the whole picture a certain sense of hierarchy. This will give people an intuitive and strong visual feeling, thus achieving the purpose of "visual communication". In 3D ink rendering technology, image processing and sound effects are the two most important aspects. Among them, there is a certain correlation between digital works and text and other multimedia contexts with strong and far-reaching art effects rendering; and the impact of color and sound effects on 3D scenes should not be ignored: from the overall perspective, the sense of picture and enhanced visual effects can enhance the virtual reality space atmosphere and enrich the visual experience; but from the specific content, this may reduce the efficiency of the rendering process. In this paper, we start from the principle of ink rendering algorithm and analyze its impact on the picture effect and color processing in combination with 3D ink rendering technology.

A seamless authentication for intra and inter metaverse platforms using blockchain

The metaverse is a concept that refers to a virtual reality space where people can interact with each other and their surroundings in a virtual world. It is a vital to prioritize security and adopt security measures in metaverse environment to protect users from potential risks and threats. By implementing strong mutual authentication and authorization controls, the metaverse can be a safer place where people can freely interact and engage without worrying about their security. In this paper, we aim to address the above challenges by integrating blockchain into the metaverse. Furthermore, the use of cryptography in blockchain ensures that each user’s identity and personal information remain safe and secure. Trust and confidence are ensured through a seamless mutual authentication algorithm between the server-avatar and the avatar–avatar in the intra and inter domains of the metaverse. Moreover, the proposed approach makes it possible to manage the personal information of avatars autonomously without resorting to a trusted authority. We prove that the proposed system can resist malicious security attacks and ensures privacy preservation by performing security analyses, using AVISPA tool and BAN logic. In addition, the results of computation cost, communication cost and round trip delay (RTD) prove that the performance of our proposal is better suited to the metaverse environment compared to competing systems.

Artificial intelligence powered Metaverse: analysis, challenges and future perspectives

The Metaverse, a virtual reality (VR) space where users can interact with each other and digital objects, is rapidly becoming a reality. As this new world evolves, Artificial Intelligence (AI) is playing an increasingly important role in shaping its development. Integrating AI with emerging technologies in the Metaverse creates new possibilities for immersive experiences that were previously impossible. This paper explores how AI is integrated with technologies such as the Internet of Things, blockchain, Natural Language Processing, virtual reality, Augmented Reality, Mixed Reality, and Extended Reality. One potential benefit of using AI in the Metaverse is the ability to create personalized experiences for individual users, based on their behavior and preferences. Another potential benefit of using AI in the Metaverse is the ability to automate repetitive tasks, freeing up time and resources for more complex and creative endeavors. However, there are also challenges associated with using AI in the Metaverse, such as ensuring user privacy and addressing issues of bias and discrimination. By examining the potential benefits and challenges of using AI in the Metaverse, including ethical considerations, we can better prepare for this exciting new era of VR. This paper presents a comprehensive survey of AI and its integration with other emerging technologies in the Metaverse, as the Metaverse continues to evolve and grow, it will be important for developers and researchers to stay up to date with the latest developments in AI and emerging technologies to fully leverage their potential.

A multimodal virtual vision platform as a next-generation vision system for a surgical robot

Robot-assisted surgery platforms are utilized globally thanks to their stereoscopic vision systems and enhanced functional assistance. However, the necessity of ergonomic improvement for their use by surgeons has been increased. In surgical robots, issues with chronic fatigue exist owing to the fixed posture of the conventional stereo viewer (SV) vision system. A head-mounted display was adopted to alleviate the inconvenience, and a virtual vision platform (VVP) is proposed in this study. The VVP can provide various critical data, including medical images, vital signs, and patient records, in three-dimensional virtual reality space so that users can access medical information simultaneously. An availability of the VVP was investigated based on various user evaluations by surgeons and novices, who executed the given tasks and answered questionnaires. The performances of the SV and VVP were not significantly different; however, the craniovertebral angle of the VVP was 16.35° higher on average than that of the SV. Survey results regarding the VVP were positive; participants indicated that the optimal number of displays was six, preferring the 2 × 3 array. Reflecting the tendencies, the VVP can be a neoconceptual candidate to be customized for medical use, which opens a new prospect in a next-generation surgical robot.Graphical

Improvement awareness of disaster management using virtual reality-based tsunami disaster drills

Virtual reality has the potential to be a unique tool to experience simulated disasters in a dynamic and immersive environment. Researchers thus developed an experience-based tsunami drill in a virtual reality space using a tsunami evacuation simulation on a head-mounted display. A 3D model of Mikuni-Minato area, Sakai City, Fukui Prefecture, Japan, was built based on data. Questionnaires survey were supplied to 28 participants who were residents of the Mikuni-Minato area. The questionnaire included items on the effectiveness of tsunami simulation, evacuation behavior, awareness of disaster management and possible future actions after the evacuation drill. The findings reveal that the evacuation drill effectively improved awareness of disaster management among local residents. In particular, 46.4% stated “I decided to improve the evacuation route,” 67.9% stated “I realized that disaster drills were important,” and 60.1% stated “Will prepare disaster goods.” While the study confirmed the effectiveness of VR-based drills using head-mounted devices, we suggest further improvements to make the simulations more realistic.

Reshaping the peripersonal space in virtual reality

Peripersonal space (PPS) is defined as the space that lies within reach. Previous research revealed that PPS can be dynamically reshaped with the use of tools extending the arm’s reach. Here we investigated whether PPS reshaping depends on the kind of selected tool and/or the motor routine associated with its use. Participants carried out a visuo-tactile detection task in an immersive VR environment that allowed to measure the PPS size before and after a short period of tools use. In Experiment 1, participants had to pull or push objects towards or away from themselves using a shovel. In Experiment 2, they were required to either hammer or shoot an avatar placed in the Extrapersonal space. We found, for the first time in a VR environment, that a period of pull training was effective in enlarging the PPS, a result that replicates and expands previous findings carried out in real life conditions. However, no significant change in PPS size was achieved for training with other tools and motor routines. Our results suggest that the reshaping of PPS is a complex phenomenon in which the kind of interaction between the agent, the targets and the exploited motor routines all play a critical role.

The Reality of a Head-Mounted Display (HMD) Environment Tested via Lightness Perception.

Head-mounted displays (HMDs) are becoming more and more popular as a device for displaying a virtual reality space, but how real are they? The present study attempted to quantitatively evaluate the degree of reality achieved with HMDs by using a perceptual phenomenon as a measure. Lightness constancy is an ability that is present in human visual perception, in which the perceived reflectance (i.e., the lightness) of objects appears to stay constant across illuminant changes. Studies on color/lightness constancy in humans have shown that the degree of constancy is high, in general, when real objects are used as stimuli. We asked participants to make lightness matches between two virtual environments with different illuminant intensities, as presented in an HMD. The participants' matches showed a high degree of lightness constancy in the HMD; our results marked no less than 74.2% (84.8% at the maximum) in terms of the constancy index, whereas the average score on the computer screen was around 65%. The effect of head-tracking ability was confirmed by disabling that function, and the result showed a significant drop in the constancy index but that it was equally effective when the virtual environment was generated by replay motions. HMDs yield a realistic environment, with the extension of the visual scene being accompanied by head motions.

Three‐dimensional mapping and immersive human–robot interfacing utilize Kinect‐style depth cameras and virtual reality for agricultural mobile robots

AbstractNavigation and autonomous operation in farmland or greenhouse environments present significant challenges for agricultural mobile robots on account of unstructured scene conditions and complex task requirements. The immersive interfaces based on human–robot interaction have been extensively developed, which bridge the high‐level decision of human beings and the precise sensing and high motion ability of robots. In this study, we propose a human–robot interaction framework based on three‐dimensional mapping and virtual reality (VR) visualization. On the construction client, dense three‐dimensional point‐cloud maps are created based on the simultaneous localization and mapping real‐time appearance‐based mapping algorithm with a Kinect‐style depth camera. Subsequently, point‐cloud filtering and mesh creation methods are introduced for postprocessing the map models. A data communication network is employed to transmit the optimized models to the VR‐based exploration client. Utilizing VR visualization, the operator can gain an intuitive and comprehensive understanding of the environments to be explored. The three‐dimensional agricultural scenes are mapped into VR models through the system, which can combine the physical worlds with the VR spaces in a better manner. Compared with the video streaming‐based method for three‐dimensional mapping, the map models with colors and textures are entirely displayed in the VR headset, thus providing robust and global human–robot interaction interfaces and enhancing the immersive exploration for human beings to a considerable extent. Experimental results indicate that the three‐dimensional map models exhibit relatively sufficient construction integrity and yield favorable optimization effects. Additionally, according to a user questionnaire survey, immersive VR‐based interfaces can be more effectively utilized for the three‐dimensional mapping of mobile robots. Research evidence and results demonstrate that our proposed system framework offers positive assistance and support for enhancing human–robot interaction and executing specific robotic tasks in unstructured field agricultural environments. Code implementation and related data sets are shared at the link https://github.com/WangDongBUAA/Mapping_Interfacing.

Comparison of the perception of space in virtual reality and in the real world

The subject of the study is investigation the accuracy and identify the features of spatial information perception in virtual reality. During the experiment, the subjects were asked to estimate the distances to objects and between objects in virtual environment in metric units without the presence of reference objects with known dimensions in the virtual environment. It was found that in the complete absence of metric support in the action space in the real world, subjects estimated metric distances with an error of about 2 meters at 8 meters, 3 meters at 13-15 meters, and 2 meters at 30 meters. In contrast, in a virtual environment, the subjects estimated a distance of 8 meters with an error of 4 meters, a distance of 13-15 meters with an error of 7-8 meters, and a distance of 30 meters with an error of 18 meters. Introducing metric support is likely to significantly improve the result, and abandoning the metric distance measurement scale, which is not natural for humans, will considerably increase the accuracy of spatial information perception. It should be noted that in the field of long-range vision (30 meters or more) in virtual reality, the accuracy of information perception is extremely low.

Analyzing muscle thickness changes in lateral abdominal muscles while exercising using virtual reality.

[Purpose] Virtual reality (VR) rehabilitation has become popular in the medical field. VR-guided exercises (VR-ge) have demonstrated positive effects on gait and trunk control. Trunk muscle activation, particularly that of the transversus abdominis (TrA), is responsible for these improvements. However, the difference in muscle activation between VR and real space remains unclear. Therefore, this study aimed to clarify the differences in trunk muscle activation during exercise therapy performed in VR and real space. [Participants and Methods] A total of 22 healthy male volunteers were divided into two equal groups: VR-ge and Control exercise (C-e) groups. Both groups performed reaching exercises in a seated position. Ultrasound imaging was used to measure the thicknesses of the right external oblique, internal oblique, and TrA muscles, both at rest and during the reaching exercises performed in six different directions. [Results] No significant differences were observed in TrA muscle thickness changes between the groups before the intervention. However, after the intervention, the VR-ge group showed significantly greater TrA muscle thickness changes during reaching compared to that of the C-e group. [Conclusion] VR-ge increased TrA activation during reaching compared to exercising in real space.

Students' Perception of Remote Extended Reality Simulation Systems Using Patient-specific Three-Dimensional-printed Models in Endodontic Education: A Pilot Study.

Extended reality (XR) technology using head-mounted devices enables the operator to visu-alise anatomical structures. We aimed to investigate student perceptions regarding applying XR simu-lation for transferring endodontic educational information between a lecturer in Japan and students in Saudi Arabia. In this study, the students engaged with an XR simulation system and viewed teeth in virtual reality (VR). Pictures of dental anatomy were shown in the VR space, allowing participants to manipulate them. Then, the participants viewed a patient-specific three-dimensional printed model and three-dimensional root canal access guide in a second VR area. Before the sessions, the students completed a questionnaire on demograph-ic data and information concerning their VR experience. After the sessions, they completed a questionnaire evaluating the XR simulation system. The questionnaire included questions on dental anatomy, root canal access, usability, emotional impression, and data transfer. Eleven 5th-year dental students, comprising six male and five female students, were enrolled; three of them had previous VR experience, whereas eight did not. The highest levels of satisfaction were noted in the tooth anatomy (4.6+-0.4) and emotional impression (4.5+-0.5) domains, whereas the lowest level was noted in the data transmission domain (3.5+-0.9). Female participants and those without previous VR experience reported higher satisfaction levels across questionnaire domains compared to male participants and those with previous VR experience. XR can be successfully used in dental education and integrated into online lectures. Restrictions on education caused by health crises can be averted by using XR. Further, fifth-generation networks can offer better data transmission than wireless fidelity.
