Active Virtual Reality Games: Comparing Energy Expenditure, Game Experience, and Cybersickness to Traditional Gaming and Exercise in Youth Aged 8-12.

Objective: The purpose of this study was to (1) quantify the oxygen consumption (VO2) and heart rate (HR) of virtual reality (VR) exergaming in youth, (2) compare the physical activity intensity of VR gaming to moderate-intensity thresholds, and (3) quantify the game experience and cybersickness of VR gaming, compared with traditional gaming. Material and Methods: Youth (N = 28; age, 9.4 ± 1.2 years) completed 10-minute conditions: seated rest, seated videogame Katamari Forever (SVG-KF), treadmill walking (TW) (5.6 km/h, 0% grade), and VR exergames Beat Saber (BS) and Thrill of the Fight (TOF) while VO2 and HR were collected. Game experience and Child Simulator Sickness Questionnaires were collected after gameplay. Results: VO2 and HR for BS (9.1 ± 3.0 mL/kg/min and 119 ± 15 bpm), TW (17.1 ± 2.4 mL/kg/min and 135 ± 15 bpm), and TOF (16.9 ± 5.4 mL/kg/min and 145 ± 19 bpm) were significantly higher than that at rest (4.2 ± 1.5 mL/kg/min and 94 ± 12 bpm) and for SVG-KF (4.3 ± 1.3 mL/kg/min and 94 ± 12 bpm). BS was light-to-moderate, whereas TW and TOF were of moderate intensity based on HR and metabolic equivalents (METs). For game experience, SVG-KF (1.6 ± 1.6) was less challenging than BS (3.3 ± 1.0) and TOF (3.1 ± 1.1). BS was more visually satisfying (3.5 ± 0.7 vs 2.7 ± 0.9) and required more concentration than SVG-KF (3.6 ± 0.7 vs 3.1 ± 1.1). TOF (3.4 ± 0.8) was more fun than SVG-KF (2.8 ± 0.7). Two youths (7%) experienced cybersickness symptoms, but neither requested to stop play. Oculomotor symptoms (0.6 ± 0.9), although minimal, were significantly greater than nausea (0.2 ± 0.5) and disorientation (0.3 ± 0.6) in both games. Conclusions: VR exergames provided light- to moderate-intensity exercise, challenge, visual stimulation, attention, and fun with minimal cybersickness symptoms, compared with conventional gameplay in youth.

The Diverse Development and Clinical Application of Game-Based Learning

The effectiveness of game-based learning strategies lies in the ability of these strategies to engage learners and enhance their motivation to learn. This is particularly important for today's younger generations, which are known to respond better to visual rather than textual information. Gamified education provides stimulating, realistic, and enjoyable learning experiences, helping students understand complex nursing knowledge and skills. The diversity of game-based learning tools, including based board games, escape room games, digital games, simulation games, mobile serious games, and virtual reality games, not only enhances students' learning effectiveness and skills but also improves their problem-solving abilities, communication skills, and ability to cope with various challenges in clinical care. In general, game-based learning is a strategy with great potential and importance. This strategy not only has profound implications for modern nursing education and clinical practice but also, through its promotion of innovative thinking and diversified applications, can effectively promote the learning motivation of nursing professionals, improve teaching effectiveness, and enhance professional abilities and self-directed learning capabilities. In an era in which medical knowledge is constantly evolving, game-based learning should be promoted and utilized to cultivate nursing professionals' capabilities effectively.

SceneFusion: Room-Scale Environmental Fusion for Efficient Traveling Between Separate Virtual Environments.

Traveling between scenes has become a major requirement for navigation in numerous virtual reality (VR) social platforms and game applications, allowing users to efficiently explore multiple virtual environments (VEs). To facilitate scene transition, prevalent techniques such as instant teleportation and virtual portals have been extensively adopted. However, these techniques exhibit limitations when there is a need for frequent travel between separate VEs, particularly within indoor environments, resulting in low efficiency. In this article, we first analyze the design rationale for a novel navigation method supporting efficient travel between virtual indoor scenes. Based on the analysis, we introduce the SceneFusion technique that fuses separate virtual rooms into an integrated environment. SceneFusion enables users to perceive rich visual information from both rooms simultaneously, achieving high visual continuity and spatial awareness. While existing teleportation techniques passively transport users, SceneFusion allows users to actively access the fused environment using short-range locomotion techniques. User experiments confirmed that SceneFusion outperforms instant teleportation and virtual portal techniques in terms of efficiency, workload, and preference for both single-user exploration and multi-user collaboration tasks in separate VEs. Thus, SceneFusion presents an effective solution for seamless traveling between virtual indoor scenes.

Application and Effectiveness of Virtual Reality in Teaching Basic Concepts to Children with Autism Spectrum Disorder

Background: This study compares traditional teaching methods with cutting-edge virtual reality (VR) technology to assess its effectiveness in teaching basic concepts to children with autism spectrum disorder (ASD). Methods: Thirty-two children with ASD were included in the study and randomly assigned to either the VR or the control group. For the VR group, a teaching material was developed as an easy-to-play VR game called Geometry Park to teach concepts of shapes and colors to children with ASD, by virtually traveling through a world filled with geometrical shapes in different colors and sizes. For the control group, similar teaching material was prepared using flashcards with shapes and colors similar to those in Geometry Park. Each subject underwent ten play-and-learn sessions. At the end of the sessions, the research assistant asked them to identify 23 shapes and colors using "test flash cards" and reported the scores for each item. Results: The result of the two-sample t-test did not show a statistically significant difference between the means of the two groups (P=0.45), which might be a false negative due to Type II error. However, a medium effect size was observed for the VR group compared to the control group (Cohen’s d=0.39). Conclusion: The results of this experiment did not demonstrate a statistically significant difference between the VR and the control groups. However, a medium effect size was found for the VR group, which is "clinically significant".

Analysis of asymmetric VR games – Steam platform case study

The paper presents research on the topic of asymmetric virtual reality (VR) games. These types of applications are in the development phase when it comes to their presence on the market, range, amount, and popularity. This research discusses the original topic, as it is still a niche compared to video games and even to VR applications on the market. The article presents a quantitative analysis of asymmetric VR applications available in the international market. One of the popular gaming platforms, Steam, was chosen as a subject for the case study in this investigation. The objectives of the conducted research include, first, a quantitative analysis and presentation of up-to-date data on asymmetric VR games available on Steam; then, providing and systematizing new knowledge about the asymmetric VR term, identifying the nature of asymmetric VR games, and finally, recognition of the current situation and the latest trends within the concept of asymmetric VR. Based on the results, it was concluded that the dominating genre of asymmetric VR was action (49.4 %), indie (46.0 %) and casual (45.4 %), followed by simulation (37.4 %). Most of the games were available in English (96.6 %), and far behind English, there were French and German languages (30.5 %), and then Spanish – Spain (28.2 %), Russian (27 %), Japanese (25.9 %), simplified Chinese (25.3 %) and others. The analysis of user re-views on Steam that asymmetric VR receive favorable feedback, with ‘very positive’ as the most prevalent label, representing 35.0 % of analyzed games. Notably, only four games achieved the ‘overwhelmingly positive’ label, including ‘Keep Talking and Nobody Explodes’ in the basic version and in the version with soundtrack (97 % positive reviews), ‘Rock Life: The Rock Simulator’ (95 % positive reviews), and ‘IronWolf VR’ (95 % positive reviews). Last but not least, the paper describes the features of the analyzed asymmetric VR application. The results of the research make a contribution to the field and provide new knowledge on the following: the new subarea of VR, the nature of asymmetric VR (author's concept), human behavior and interaction in asymmetric virtual gameplay, and communication in asymmetric VR.

A Study on the Effectiveness of VR Rehabilitation Training Content for Older Individuals with Total Knee Replacement: Pilot Study.

There is a paucity of research applying fully immersive virtual reality (VR) training to older adults with degenerative joint disease. This study investigated the effects of a training program utilizing fully immersive VR games on proprioception and gait ability in older patients with degenerative arthritis who had undergone total knee arthroplasty. This randomized controlled trial enrolled patients aged ≥65 years who were diagnosed with knee joint arthritis and had undergone knee arthroplasty followed by physical therapy. Participants were randomly assigned to an experimental group (receiving training using fully immersive VR games along with regular physical therapy) and a control group (receiving only regular physical therapy). The intervention was conducted five times a week for four weeks. Knee joint proprioception was measured using Biodex before and after the intervention. Spatial-temporal gait variables were collected using OptoGait for gait assessment. There was a significant decrease in the absolute error values of proprioception after the intervention in the experimental group, compared to before (p < 0.05), indicating improvement in proprioception. Gait speed, step count, and stride length improved significantly (p < 0.05, p < 0.01), demonstrating an enhancement in gait ability. The experimental group showed significantly greater improvements in gait speed, step count, and stride length than the control group (p < 0.01). Training using a fully immersive VR exercise program may have potential benefits for improving proprioception and gait parameters in patients who have undergone total knee arthroplasty. Fully immersive VR game-based training can be utilized as an effective rehabilitation intervention for patients undergoing knee arthroplasty in the future.

An Empirical Study of VR Head-Mounted Displays Based on VR Games Reviews

With the development of virtual reality (VR) technology, various VR devices are flooding the market. VR head-mounted displays (HMDs) sales are overgrowing as the primary medium for experiencing VR games. Therefore, exploring user concerns about HMDs is significant, enabling developers to design better VR devices and VR games. In this work, we conduct an empirical study of 7,413 VR games and 176,428 player reviews collected from three platforms (i.e., Oculus, Steam, and Viveport). First, we investigate the evolutionary trends of HMDs based on VR games. Subsequently, we extract nine topics (e.g., cybersickness, performance, and privacy) related to HMDs from game reviews that users are concerned about, analyze the emotional trends, and explore the voices of players. We find that users complain less about the cybersickness and immersion of HMDs and more about other topics (e.g., performance, tracking, and compatibility). In addition, more users have expressed concerns about privacy in recent years.

What Are the Points of Concern for Players about VR Games: An Empirical Study based on User Reviews in Different Languages

In recent years, the boom of Virtual Reality (VR) technology has signaled fruitful applications in various fields, such as education, industry, animation, entertainment, game, and so forth. The global VR games market is projected to grow to $53.44 billion in 2028 at a CAGR of 31.4% in the 2021-2028 period. Therefore, what players care about most about VR games is a topic worthy of research. In this paper, we conduct an in-depth study of 1362 VR games and 484070 reviews on the Steam platform. Unlike other literature focusing only on monolingual reviews (such as English), we apply the topic clustering model (BERTopic) to comprehensively analyze multilingual user reviews, including English, Simplified Chinese, and French. We find that the three features people praise the most are the music, the gaming experience, and the gameplay. Meanwhile, gamers’ most common complaints are bug issues, insufficient content, and excessive pricing.

Application of hybrid SSVEP + P300 brain computer interface to control avatar movement in mobile virtual reality gaming environment

IntroductionThis research evaluated the feasibility of a hybrid SSVEP + P300 brain computer interface (BCI) for controlling the movement of an avatar in a virtual reality (VR) gaming environment (VR + BCI). Existing VR + BCI gaming environments have limitations, such as visual fatigue, a lower communication rate, minimum accuracy, and poor system comfort. Hence, there is a need for an optimized hybrid BCI system that can simultaneously evoke the strongest P300 and SSVEP potentials in the cortex. MethodsA BCI headset was coupled with a VR headset to generate a VR + BCI environment. The author developed a VR game in which the avatar’s movement is controlled using the user's cortical responses with the help of a BCI headset. Specifically designed visual stimuli were used in the proposed system to elicit the strongest possible responses from the user's brain. The proposed system also includes an auditory feedback mechanism to facilitate precise avatar movement. Results and conclusionsConventional P300 BCI and SSVEP BCI were also used to control the movements of the avatar, and their performance metrics were compared to those of the proposed system. The results demonstrated that the hybrid SSVEP + P300 BCI system was superior to the other systems for controlling avatar movement.

Categorical Codebook Matching for Embodied Character Controllers

Translating motions from a real user onto a virtual embodied avatar is a key challenge for character animation in the metaverse. In this work, we present a novel generative framework that enables mapping from a set of sparse sensor signals to a full body avatar motion in real-time while faithfully preserving the motion context of the user. In contrast to existing techniques that require training a motion prior and its mapping from control to motion separately, our framework is able to learn the motion manifold as well as how to sample from it at the same time in an end-to-end manner. To achieve that, we introduce a technique called codebook matching which matches the probability distribution between two categorical codebooks for the inputs and outputs for synthesizing the character motions. We demonstrate this technique can successfully handle ambiguity in motion generation and produce high quality character controllers from unstructured motion capture data. Our method is especially useful for interactive applications like virtual reality or video games where high accuracy and responsiveness are needed.

Effect of Elastic Resistance on Exercise Intensity and User Satisfaction While Playing the Active Video Game BoxVR in Immersive Virtual Reality: Empirical Study.

One of the main contemporary forms of physical activity (PA) involves exercises and games in an immersive virtual reality (VR) environment, which allows the user to practice various forms of PA in a small space. Unfortunately, most of the currently available VR games and workout applications are mostly based on upper body movements, especially the arms, which do not guarantee sufficiently high exercise intensity and health benefits. Therefore, it is worth seeking solutions to help increase the exercise load during PA in VR. The main aim of this study was to evaluate the effect of elastic arm resistance in the form of latex resistance bands of different elasticity levels on the intensity of students' PA while playing the BoxVR game. We further assessed the satisfaction of this form of exercise and its associations with PA intensity. A total of 21 healthy and physically fit men (mean age 22.5, SD 2.0 years) were included in the study. The tests consisted of 3 10-minute games. One game was run with no load and the other two were run with 1.5-meter latex resistance bands (low and high resistance). The order of the tests was randomized and the participants rested for 20 minutes after each exercise. Exercise intensity was estimated using objective (heart rate monitoring) and subjective (Borg scale) methods. The Physical Activity Enjoyment Scale was used to assess satisfaction with the PA. The effect of elastic resistance on exercise intensity and user enjoyment was estimated using ANOVA for repeated measures. The ANOVA results indicated that incorporation of elastic resistance caused a significant change (F2,40=20.235, P<.001; η²p=0.503) in the intensity of PA in VR, which was low while playing without resistance and then increased to a moderate level with additional resistance. The use of elastic bands also changed participants' perceptions of the enjoyment of exercise in VR (F2,40=9.259, P<.001; η²p=0.316). The students rated their satisfaction with PA in VR on a 7-point scale highly and similarly when exercising without an upper limb load (mean 6.19, SD 0.61) and with slight elastic resistance (mean 6.17, SD 0.66), whereas their satisfaction declined significantly (mean 5.66, SD 0.94) when incorporating a higher load. The intensity of PA among students playing the BoxVR game is at a relatively low level. With the added resistance of elastic bands attached to the upper limbs, the intensity of the exercise increased to a moderate level, as recommended for obtaining health benefits. Participants rated the enjoyment of PA in VR highly. The use of slight elastic resistance did not negatively affect satisfaction with the BoxVR game, although user satisfaction declined with a higher load. Further research should be undertaken to increase the effectiveness of exercise in VR so that regular users can enjoy the health benefits.

Eliciting guilt in virtual reality games: interplay of self-attribution, presence, and morality.

This study investigates the psychological mechanisms in virtual reality (VR) games, focusing on the interplay between character morality, self-attribution, presence, guilt, and their collective impact on player enjoyment. Based on Affective Disposition Theory, it hypothesizes that players' moral judgments of characters significantly affect their engagement and enjoyment of VR narratives. A post-test between-subjects experiment was conducted with 97 participants to examine the influence of character morality on guilt through the mediation of self-attribution, and how these factors affect players' sense of presence and overall enjoyment in VR games. The findings indicate that self-attribution significantly mediates the relationship between character morality and guilt. Additionally, the sense of presence enhances enjoyment, with a stronger sense of 'being there' amplifying the emotional impact of players' moral decisions. This study highlights the full mediating effect of self-attribution in the context of VR gaming, intensifying players' emotional responses to moral dilemmas. The results suggest that VR game designers should consider the moral implications of game narratives and character actions to create more emotionally engaging and ethically reflective gaming experiences. These insights have significant implications for VR game design and ethics, promoting greater ethical sensitivity among players.

Using Digital Twin Technology to Conduct Dynamic Simulation of Industry-Education Integration

The high accident rate in the construction industry has a major impact on how well projects turn out. Despite substantial investments in safety planning and supervision, there has been a marked increase in the construction industry's accident rate compared to other sectors. Serious games based on VR have recently been used in the study, suggesting that workers are now more safety conscious. However, these situations need many resources to create and are not always realistic. Hence this paper, Digital Twin-based Construction Safety Training Framework (DT-CSTF) with Artificial Intelligence (AI), has been proposed to monitor employees' emotional, mental, and physical well-being in real-time. The report sheds light on the significance of DT technology and its function in Industry 5.0. Using the Unity game engine, the proposed DT-CSTF creates a virtual reality-based training environment (VRTE) prototype that incorporates BIM, construction timetables, and safety requirements. Following this, the suggested structure enables gathering user data about risks and providing tailored feedback. Automated virtual reality game training scenarios are created using data given by digital twins on project intent, project status, safety requirements, and history. Both improved digital twins and periodic construction safety monitoring are anticipated to reap the benefits of dynamic virtual reality training. The proposed management system offers effectiveness of VR-based security training, cost-benefit analysis, monitoring,employee behaviour, safety education values are obtained by the ratio of 96,90 %, 98,33 %, 99,25 %, 95,91 %, 98,66 % respectively

The Wonder and the Terror of Getting Lost in “The Room”

This paper deals explicitly with two competing definitions of wonder. On the one hand, we have something like Mary-Jane Rubenstein’s strange wonder where the very ground on which we stand is shaken and aporias determine our interaction with the world via wonder. We lose the very foundation on which we understand reality and thereby call into question our epistemological grasp of the world. On the other hand, we have Jan B.W. Pedersen’s epistemological wonder where wonder is a kind of surprise or presentation of reality where we are struck by an epistemological lack. Wonder urges us forward in hopes of strengthening and broadening our understanding of the world. Both definitions seem to coalesce in the project of unveiling the reality of the world. Pedersen’s project is explicitly epistemological in that wonder, be it an emotion or some kind of noetic faculty, reveals the world to us in a way that we didn’t know before. Rubenstein, on the other hand, moves beyond epistemology by attempting a kind of strange ontology that opens new possibilities that were not previously accessible. In both versions, we end up peeling away a filmy layer of the world to find some other reality. In this paper, I will argue that there is a tension between wonder and terror that shows up in between Rubenstein’s and Pedersen’s definitions; a kind of wonder that attends to, at least partially, the filmy veil of reality. To do this, I will appeal to Weird fictions, including the virtual reality (VR) game, The Room, to pull at this tension and demonstrate its generativity for thinking through experiences of wonder and terror, including how they frame the meaning of our world(s).

Non-Perceptual Representational Immersion in Video Games: a Response to David Chalmers’ Reality+

This article criticises David Chalmers’ ‘Reality+’ by interrogating its distinction of virtual reality (VR) from 2D, non-VR video games, a distinction made on the grounds that VR is immersive and these types of video games are not because immersion is a distinct characteristic of 3D perceptually represented VR. Building on the Balcerak Jacksons’ account of ‘representational immersion’, which they acknowledge has ‘perceptual’ and ‘non-perceptual’ elements, I develop an account of ‘non-perceptual representational immersion’ and use it to critique Chalmers’ treatment of VR, immersion, and video games, indirectly problematizing his central ontological claim that ‘virtual reality is genuine reality’ and the reflections he makes about future society which rest upon it. I argue that video games are rich in non-perceptual representational immersion, which includes the representation of non-perceptual information about the structure and behaviour of a virtual world and its systems, the non-perceptual cognitive states that are generated in the player by the virtual world, and the immersion which comes from the constitutively cognitive nature of the player’s engagement with the virtual world, a cognitive engagement construed in an enactive sense. These are just as crucial to the phenomenon of digital immersion as perception. Immersion generally is a much more complicated phenomenon than Chalmers allows for, and it is better conceived as taking place on a spectrum which includes both 3D and 2D experiences of virtual worlds, not as hinging on 3D perceptual representation. I use ‘immersive simulation’ games as a case study.

Undergraduates’ process safety knowledge development with virtual reality game

ABSTRACT Despite the movement to improve process safety, incidents in chemical-related industries are still occurring around the world. Personnel process safety lack of knowledge is a typical cause of these events. Process safety is an integral part of a chemical engineer’s work. Employees’ discontent with chemical engineering graduates’ process safety understanding revealed deficiencies in undergraduate courses. Inadequate accident investigation and prevention training has also hampered graduates’ knowledge and preparation for high-risk jobs. To address the gaps, an online game platform was suggested and tested with 450 undergraduate students at different levels and disciplines. Virtual reality process safety game proven to improve chemical engineering graduates’ process safety competency while delivering industry experience. The approach is also believed to improve students’ problem-solving and decision-making skills and motivate engagement to study process safety. The main features of the game are desired to be online web-based with serious role-play integrated into real-life simulation activities.

Pericles VR: towards pedagogical innovation through gamified adaptation of classic literature

ABSTRACT Our paper seeks to investigate how mediation using emerging technologies can increase student engagement within the context of teaching English Literature in Singapore. Through a discussion of our ongoing project to create an adaptation of Shakespeare’s Pericles, Prince of Tyre as an animated game in virtual reality, we focus upon the interdependencies between narrative content, style of visualization and interactive engagement to demonstrate the potential of fully immersive media in an educational context. Pericles is one of Shakespeare’s lesser-known plays: in five acts, it tells the dramatic story of a family separated at sea and reunited by fate. Our findings will highlight the opportunities that works of Shakespeare that fall outside the group of texts commonly studied offer for innovation within the classroom, as well as the benefits of taking a practice-led approach to research that draws together Shakespeare scholars, artists, researchers, and technical developers to adopt a playful yet meaningful approach towards educating secondary-level students. Most importantly, however, we will focus on demonstrating how our adaptation facilitates conclusions regarding employing animated immersive media for novel ways of teaching “boring”, complex, canonical literary texts. We suggest our adaptation prompts a reconsideration of means of student engagement for classical literature in general, and Shakespeare’s work in particular.

Prior exposure to a sensorimotor game in virtual reality does not enhance stress reactivity toward the OpenTSST VR

Compared to the in-person Trier Social Stress Test (TSST), virtual reality (VR) variants reduce resource-intensity and improve standardization but induce stress with smaller effect sizes. However, higher cortisol reactivity is given for more immersive TSST-VRs. Immersivity depends on the VR-system, but perceived immersion may be targeted by exposure to, or interaction with the VR. We investigated whether stress reactivity towards the openly accessible OpenTSST VR can be enhanced by prior exposure to a sensorimotor game completed in VR as mediated by increased immersion. Therefore, N = 58 healthy participants underwent the OpenTSST VR or its inbuilt control condition (placebo TSST-VR, pTSST-VR). Beforehand, participants completed a sensorimotor game either in VR or in real life. Stress was measured by means of self-reports, salivary cortisol concentrations, and salivary alpha-amylase (sAA) activity. Perceived immersion was assessed with the Igroup Presence Questionnaire (IPQ). The TSST-VR-group showed higher subjective stress than the pTSST-VR-group. Even though area under the curve measures indicated significant differences in cortisol levels between TSST-VR and pTSST-VR, this effect was not replicated in omnibus-analyses. Likewise, sAA was not responsive to stress. Our data suggests the OpenTSST VR does not reliably trigger physiological stress reactivity. Likewise, participants playing the VR-game before exposure to the TSST-VR did not show enhanced stress reactivity. Importantly, playing the VR-game did not lead to increased immersion (indicated by the IPQ), either. The key question resulting from our study is which manipulation may be fruitful to obtain a comparable stress response toward the TSST-VR compared to the in-person TSST.

Nursing Students' Experiences of Empathy in a Virtual Reality Simulation Game: A Descriptive Qualitative Study.

Empathy is significant in nursing, and showing empathy toward a patient positively impacts a patient's health. Learning empathy through immersive simulations is effective. Immersion is an essential factor in virtual reality. This study aimed to describe nursing students' experiences of empathy in a virtual reality simulation game. Data were collected from nursing students (n = 20) from May 2021 to January 2022. Data collection included individual semistructured interviews; before the interviews, the virtual reality gaming procedure was conducted. Inductive content analysis was used. Nursing students experienced compassion and a feeling of concern in the virtual reality simulation game. Students were willing to help the virtual patient, and they recognized the virtual patient's emotions using methods such as listening and imagining. Students felt the need to improve the patient's condition, and they responded to the virtual patient's emotions with the help of nonverbal and verbal communication and helping methods. Empathy is possible to experience by playing virtual reality simulation games, but it demands technique practicing before entering the virtual reality simulation game.
