Remote research on locomotion interfaces for virtual reality: Replication of a lab-based study on teleporting interfaces.

The wide availability of consumer-oriented virtual reality (VR) equipment has enabled researchers to recruit existing VR owners to participate remotely using their own equipment. Yet, there are many differences between lab environments and home environments, as well as differences between participant samples recruited for lab studies and remote studies. This paper replicates a lab-based experiment on VR locomotion interfaces using a remote sample. Participants completed a triangle-completion task (travel two path legs, then point to the path origin) using their own VR equipment in a remote, unsupervised setting. Locomotion was accomplished using two versions of the teleporting interface varying in availability of rotational self-motion cues. The size of the traveled path and the size of the surrounding virtual environment were also manipulated. Results from remote participants largely mirrored lab results, with overall better performance when rotational self-motion cues were available. Some differences also occurred, including a tendency for remote participants to rely less on nearby landmarks, perhaps due to increased competence with using the teleporting interface to update self-location. This replication study provides insight for VR researchers on aspects of lab studies that may or may not replicate remotely.

Personalizing Virtual Reality for the Research and Treatment of Fear-Related Disorders: A Mini Review

This mini review presents the current state of the art in studies on the personalization of virtual reality for basic research and treatment of fear-related disorders. Of particular interest to the review are the choice of self-report measures and manipulations of contextual factors that researchers are using in their virtual reality procedures. As this mini review will show, work is starting to emerge on the area of the interaction between context and individual differences, yet this topic remains a current gap in the literature on fear learning mechanisms and therapies for fear-related disorders. Studies in this review conclude that virtual reality environments offer many advantages, as they can be adjusted to model different contexts with great precision and control of the experimental context. Virtual reality is also seen by researchers as an opportunity to decrease the translational gap that exists between the research laboratories and the practical use for therapy treatments in clinics. However, the heterogeneity of methodological approaches that have created replicability as well as comparability issues in the field of fear learning is also a concern in studies using virtual reality. Thus, another, albeit secondary, aim of this mini review will be to point out some of the methodological challenges that should be addressed in future research aimed at the personalization of virtual reality for the research and treatment of fear-related disorders. Factors that will be addressed are 1) the use of self-report measures, and 2) interactivity aspects of contextual factor design in the virtual reality environment.

A survey of challenges and methods for Quality of Experience assessment of interactive VR applications

User acceptance of virtual reality (VR) applications is dependent on multiple aspects, such as usability, enjoyment, and cybersickness. To fully realize the disruptive potential of VR technology in light of recent technological advancements (e.g., advanced headsets, immersive graphics), gaining a deeper understanding of underlying factors and dimensions impacting and contributing to the overall end-user experience is of great benefit to hardware manufacturers, software and content developers, and service providers. To provide insight into user behaviour and preferences, researchers conduct user studies exploring the influence of various user-, system-, and context-related factors on the overall Quality of Experience (QoE) and its dimensions. When planning and executing such studies, researchers are faced with numerous methodological challenges related to study design aspects, such as specification of dependant and independent variables, subjective and objective assessment methods, preparation of test materials, test environment, and participant recruitment. Approaching these challenges from a multidisciplinary perspective, this paper reviews different aspects of performing perception-based QoE assessment for interactive VR applications and presents options and recommendations for research methodology design. We provide an overview of different influence factors and dimensions that may affect the overall QoE, with a focus on presence, immersion, and discomfort. Furthermore, we address ethical and practical issues regarding participant choice and test material, present different assessment methods and measures commonly used in VR research, and discuss approaches to choosing study duration and location. Lastly, we provide a concise analysis of key challenges that need to be addressed in future studies centered around VR QoE.

Perspectives of 360-Degree Cinematic Virtual Reality: Interview Study Among Health Care Professionals.

BackgroundThe global market for medical education is projected to increase exponentially over the next 5 years. A mode of delivery expected to drive the growth of this market is virtual reality (VR). VR simulates real-world objects, events, locations, and interactions in 3D multimedia sensory environments. It has been used successfully in medical education for surgical training, learning anatomy, and advancing drug discovery. New VR research has been used to simulate role-playing and clinical encounters; however, most of this research has been conducted with health professions students and not current health care professionals. Thus, more research is needed to explore how health care professionals experience VR with role-playing and clinical encounters.ObjectiveThe aim of this study was to explore health care professionals’ experiences with a cinematic VR (cine-VR) training program focused on role-playing and clinical encounters addressing social determinants of health, Appalachian culture, and diabetes. Cine-VR leverages 360-degree video with the narrative storytelling of cinema to create an engaging educational experience.MethodsWe conducted in-depth telephone interviews with health care professionals who participated in the cine-VR training. The interviews were audio recorded and transcribed verbatim. A multidisciplinary team coded and analyzed the data using content and thematic analyses with NVivo software.ResultsWe conducted 24 in-depth interviews with health care professionals (age=45.3, SD 11.3, years; n=16, 67%, women; n=22, 92%, White; and n=4, 17%, physicians) to explore their experiences with the cine-VR training. Qualitative analysis revealed five themes: immersed in the virtual world: seeing a 360-degree sphere allowed participants to immerse themselves in the virtual world; facilitated knowledge acquisition: all the participants accurately recalled the culture of Appalachia and listed the social determinants of health presented in the training; empathized with multiple perspectives: the cine-VR provided a glimpse into the real life of the main character, and participants described thinking about, feeling, and empathizing with the character’s frustrations and disappointments; perceived ease of use of cine-VR: 96% (23/24) of the participants described the cine-VR as easy to use, and they liked the 360-degree movement, image resolution, and sound quality but noted limitations with the buttons on the headsets and risk for motion sickness; and perceived utility of cine-VR as a teaching tool: participants described cine-VR as an effective teaching tool because it activated visual and affective learning for them.ConclusionsParticipants emphasized the realism of the cine-VR training program. They attributed the utility of the cine-VR to visual learning in conjunction with the emotional connection to the VR characters. Furthermore, participants reported that the cine-VR increased their empathy for people. More research is needed to confirm an association between the level of immersion and empathy in cine-VR training for health care professionals.

VESPA project generations are then presented in detail, including specific session/task battery characteristics, 2.5D, 3D and 5D typologies, system usability and architecture and pathological domain-based dynamics and features. The discussion about VESPA will highlight the current advantages along with limitations and future directions.

Immersive netnography: a novel method for service experience research in virtual reality, augmented reality and metaverse contexts

PurposeAs immersive technologies gain wider adoption, contemporary service researchers are tasked with studying their service experiences in ways that preserve and attend to their holistic and human characteristics. The purpose of this paper is to provide service researchers with a new qualitative approach to studying immersive technologies.Design/methodology/approachUsing logic and following established methodological rules, this article develops the scope, definition and set of procedures for a novel form of netnography specifically adapted for the study of immersive technologies: immersive netnography. The research question is “How might netnography be adapted to research service experiences in virtual and augmented environments, which include and overlap with the notion of a Metaverse?”FindingsImmersive netnography should be at the vanguard of phenomenological service experience studies of augmented reality, virtual reality and the Metaverse. A set of data collection, analysis, ethical and representational research practices, immersive netnography is adapted to digital media phenomena (customer and employee) that include immersive technology experiences. Developed through logical argumentation after analyzing key differences between social media and immersive technology, immersive netnography is procedurally customized for experience research in immersive technology environments.Research limitations/implicationsThree of the most significant practical limitations to producing high-quality netnography are rapidly changing contexts, scarce time resources and narrow researcher skillsets.Practical implicationsIndustries and organizations may benefit from a new, holistically focused, ethically robust and culturally attuned market research method for understanding service experience in immersive technology contexts.Originality/valueThere have been no prior studies that develop netnography for the service research opportunities presented by immersive technologies. By applying the rigorous methodological guidance provided in this paper, future service researchers may find value in using specifically adapted qualitative research methods to study immersive technology experiences.

Implementation Barriers to Using Virtual Reality to Administer Mindfulness Therapy: Lessons from the Field.

<h3>Introduction</h3> Virtual Reality (VR)-based meditation has shown to help increase relaxation and decrease anxiety, sadness, and anger in younger adults. However, this has not been extensively studied in older adults (Navarro-Haro et al, 2017). Furthermore, there are no standard guidelines on how VR mindfulness interventions should be implemented to ensure successful adoption and outcomes. The availability of affordable hardware and rapidly growing content that can be freely accessed in the public domain raises the possibility of VR being used in a very broad range of clinical and in-home settings. The goal of this study is to describe and highlight some key considerations and challenges when implementing VR mindfulness interventions in older adults. <h3>Methods</h3> We set up VR mindfulness interventions in two different settings (outpatient and inpatient) and used two different headsets. Each setting was a site for an IRB-approved pilot trial of VR-based mindfulness. In setting 1, we set up a twice weekly VR guided meditation outpatient program using Oculus Quest 2 VR Headsets for older adults over a 4-week period. In setting 2, we set-up VR, a guided mindfulness inpatient group intervention, using Destek V5 headset for older adults over the course of 3 consecutive days. While the studies themselves have not formally commenced at the time of submission, researchers encountered and had to negotiate several challenges and barriers to implementing VR. Based on consensus and review over 6 months of study pre-launch, the research teams documented a broad set of practical challenges that impact scalability of VR in research and care. <h3>Results</h3> We identified multiple barriers that needed to be considered and overcome to design and pragmatic and scalable VR interventions. Primary challenges are enumerated below: (1) A major challenge is the scarcity of mindfulness-compatible virtual reality videos (360 videos) available for Oculus Quest 2 VR and DESTEK V5 VR Headset on platforms like YouTube. (2) It is also challenging to standardize the quality and content of the video (e.g. embedding a standardized narration to guide the mindfulness practice in public-domain video content given the limited options to create and alter content. Additionally, using headphones to separately play a narration adds complexity and takes away from the immersive nature of VR). (3) While nature videos and apps were an intuitive fit, we found that majority of the available content is meant for recreational virtual reality and are not suitable for mindfulness. (4) There are commercial interruptions on several platforms, which are disruptive for a mindfulness intervention. A potential solution is selecting nature scenes on Google Earth. Although the images are static and thus less dynamic, we circumvent many of the obstacles encountered on YouTube. Finally, when using the DESTEK V5 VR we were required to use a smartphone, and there were privacy issues that we had to consider. If the participant uses their personal phone, they would agree to the privacy terms and conditions of the apps being used to do VR, for example, Google Earth and YouTube. <h3>Conclusions</h3> Mindfulness intervention using virtual reality might be an effective way to address stress in older adults. However, there are many details that must be accounted for before applying these interventions. This study is a first step to establishing best practices and standardizing VR mindfulness interventions in older adults. <h3>This research was funded by</h3> This project was supported in part by an FRQS grant awared to Dr. Soham Rej and an unrestricted philanthropic gift to the McLean Technology and Aging Lab by Eric Warren Goldman.

EmteqPRO—Fully Integrated Biometric Sensing Array for Non-Invasive Biomedical Research in Virtual Reality

Virtual Reality (VR) enables the simulation of ecologically validated scenarios, which are ideal for studying behaviour in controllable conditions. Physiological measures captured in these studies provide a deeper insight into how an individual responds to a given scenario. However, the combination of the various biosensing devices presents several challenges, such as efficient time synchronisation between multiple devices, replication between participants and settings, as well as managing cumbersome setups. Additionally, important salient facial information is typically covered by the VR headset, requiring a different approach to facial muscle measurement. These challenges can restrict the use of these devices in laboratory settings. This paper describes a solution to this problem. More specifically, we introduce the emteqPRO system which provides an all-in-one solution for the collection of physiological data through a multi-sensor array built into the VR headset. EmteqPRO is a ready to use, flexible sensor platform enabling convenient, heterogenous, and multimodal emotional research in VR. It enables the capture of facial muscle activations, heart rate features, skin impedance, and movement data—important factors for the study of emotion and behaviour. The platform provides researchers with the ability to monitor data from users in real-time, in co-located and remote set-ups, and to detect activations in physiology that are linked to arousal and valence changes. The SDK (Software Development Kit), developed specifically for the Unity game engine enables easy integration of the emteqPRO features into VR environments.Code available at: (https://github.com/emteqlabs/emteqvr-unity/releases)

VR and AR virtual welding for psychomotor skills: a systematic review.

Virtual reality (VR) and augmented reality (AR) continue to play an important role in vocational training in the current pandemic and Industrial Revolution 4.0 era. Welding is one of the highly demanded vocational skills for various manufacturing and construction industries. Students need to undergo many practical sessions to become skilful welders. However, conventional training is very costly in terms of material, time, and infrastructure. Hence, we explore the intervention of VR and AR in welding training, which includes the research purposes, VR and AR technologies, and welding concepts and activities. We performed a comprehensive search of articles from the year 2000 to 2021. After filtering through inclusion criteria and full-text assessment, a total of 42 articles were coded and evaluated. While there has been growth in VR and AR welding training research, there is little discussion in their effectiveness for supporting distance learning, and most studies targeted entry-level students. Our main contributions are classifying primary functions in the virtual welding workshops and their adaptation to the psychomotor domain. We hope these results can empower the research community to develop and improve the VR and AR system and evaluation instruments to support vocational training, especially during this pandemic.

Older Adults’ Concurrent and Retrospective Think-Aloud Verbalizations for Identifying User Experience Problems of VR Games

AbstractWhile virtual reality (VR) games are beneficial for older adults to improve their physical functions and cognitive abilities, VR research often does not include older adults. Our review of the proceedings of major HCI conferences (i.e. ASSETS, CHI, CHI PLAY, CSCW and DIS) between 2016 and 2020 shows that only three out of 352 VR-related papers involved older adults. Consequently, older adults tend to encounter user experience (UX) problems with VR. One common way to identify UX problems is to conduct usability testing with think-aloud (TA) protocols. As VR games tend to be perceptually and physically demanding, older adults might need to allocate more resources to VR content and interaction and thus have fewer resources for thinking aloud. This raises the question of whether TA protocols are still a viable approach to detecting UX problems of VR games for older adult participants. To answer this question, we conducted usability testing with older adults who played two common types of VR games (i.e. the exergame and experience game) using concurrent and retrospective TA protocols (i.e. CTA and RTA), which are widely used in the industry. We analyzed participants’ TA verbalizations and uncovered how different categories of verbalizations indicate UX problems. We further show how older adults perceived the effects of thinking aloud on their game experiences in two TA protocols and offer design implications.

Virtual Reality Aided Therapy towards Health 4.0: A Two-Decade Bibliometric Analysis.

Health 4.0 aligns with Industry 4.0 and encourages the application of the latest technologies to healthcare. Virtual reality (VR) is a potentially significant component of the Health 4.0 vision. Though VR in health care is a popular topic, there is little knowledge of VR-aided therapy from a macro perspective. Therefore, this paper was aimed to explore the research of VR in aiding therapy, thus providing a potential guideline for futures application of therapeutic VR in healthcare towards Health 4.0. A mixed research method was adopted for this research, which comprised the use of a bibliometric analysis (a quantitative method) to conduct a macro overview of VR-aided therapy, the identification of significant research structures and topics, and a qualitative review of the literature to reveal deeper insights. Four major research areas of VR-aided therapy were identified and investigated, i.e., post-traumatic stress disorder (PTSD), anxiety and fear related disorder (A&F), diseases of the nervous system (DNS), and pain management, including related medical conditions, therapies, methods, and outcomes. This study is the first to use VOSviewer, a commonly used software tool for constructing and visualizing bibliometric networks and developed by Center for Science and Technology Studies, Leiden University, the Netherlands, to conduct bibliometric analyses on VR-aided therapy from the perspective of Web of Science core collection (WoSc), which objectively and visually shows research structures and topics, therefore offering instructive insights for health care stakeholders (particularly researchers and service providers) such as including integrating more innovative therapies, emphasizing psychological benefits, using game elements, and introducing design research. The results of this paper facilitate with achieving the vision of Health 4.0 and illustrating a two-decade (2000 to year 2020) map of pre-life of the Health Metaverse.

A study of how immersion and interactivity drive VR learning

Even though learning refers to both a process and a product, the former tends to be overlooked in educational virtual reality (VR) research. This study examines the process of learning with VR technology using the Cognitive Affective Model of Immersive Learning (CAMIL) as its framework. The CAMIL theorizes that two technological features of VR, interactivity and immersion, influence a number of cognitive and affective variables that may facilitate or hinder learning. In addition, VR studies often involve media comparisons that make it difficult to disentangle the relative effects of technological features on learning. Therefore, this study also aims to provide insights concerning the unique and combined effects of interactivity and immersion on the cognitive and affective variables specified by CAMIL. We employed a 2 × 2 between-subjects design (N = 153) and manipulated the degree of interactivity and immersion during a virtual lesson on the topic of viral diseases. Analyses of variance (ANOVAs) were used to examine the effects of interactivity and immersion on our variables of interest, and structural equation modeling (SEM) was used to assess the process of learning as predicted by the CAMIL. The results indicated that the process of learning involves situational interest and embodied learning. Main effects of interactivity and/or immersion on cognitive load, situational interest, and physical presence are also reported in addition to interaction effects between immersion and interactivity on agency and embodied learning. The findings provide evidence for the CAMIL and suggest important additions to the model. These findings can be used to provide a better understanding of the process of learning in immersive VR and guide future immersive learning research.

Changing social attitudes with virtual reality: a systematic review and meta-analysis

ABSTRACT Although it has been shown that Virtual Reality (VR) can positively impact political, civic and environmental views, the question of whether and how VR influences social attitudes more effectively than less immersive conditions has been a subject of debate. To address this question, this article provides a systematic review with meta-analysis of social attitude research in VR by examining 50 separate findings from 39 studies. We find that VR influences social attitudes significantly more than non-immersive interventions, while embodiment has no moderation effect. Further, outgroup VR perspective-taking fosters positive social attitudes more effectively than ingroup VR perspective-taking. Findings are categorized according to social attitude object and discussed in the light of emerging challenges and opportunities for VR attitude research.

VR in chemistry, a review of scientific research on advanced atomic/molecular visualization

Atomic/molecular visualization for human sight is usually generated by a software that reproduces a 3D reality on a 2D screen. Although Virtual Reality (VR) software was originally developed for the gaming industry, now it is used in academia for chemistry teaching. This work reviews the scientific literature on 3D visualization in stereoscopic vision, the VR. VR has the capability to simulate reality since we do not observe these real particles, but it reproduces their shapes and movements digitally. The aim of this study is to present the applications of this technology and to show the function of VR in the field of chemistry and the potential for implementation of VR in research and educational settings. The review is based on 219 articles and meeting papers, between 2018 and 2020, obtained from Web of Science (WoS). A series of registers from the WoS repository was analyzed and assigned to three groups, an analysis of 2D support software, analysis of research on Virtual Reality (VR), and research on Virtual Laboratories (VL). The research on advanced atomic/molecular simulation reveals discrepancies regarding the VR effectiveness of Chemistry teaching. Novel Virtual Reality Laboratory (VRL) methodologies are emerging that have a high impact on educational and research scenarios. VL and VRL entail several advantages and drawbacks, such as the implementation of new methodologies, the increase in the students’ motivation, the growth of new spaces for collaborative online interaction, and the interaction with physical structure of any impossible, dangerous, or not feasible elements. Finally, the article compares the main features and the learning outcomes of the VRL and the traditional laboratory.

Effectiveness of education for prospective medical personnel using VR (Virtual Reality)－Review Literature as Topic (2011∼2021)

Accordingly, it attempted to analyze and organize prospective medical personnel education research using VR within the last 10 years as a subject range literature review method to confirm the overall trend of the study, and to use it as basic data for developing education programs using VR. Method : This study was based on a review of subject-related literature published in domestic journals to understand the research trend of papers on prospective medical personnel education using VR (Virtual Reality), and was conducted in six stages as a study using scope research methodology. Results : As a result of the study, a total of 11 papers were analyzed, and there were 5 nursing papers, 5 dentistry papers, and 1 oriental medicine paper, respectively. There were 10 studies from 2019 to 2021, and it was contributed not only to professional societies in one field but also to the convergence society. Ten studies were quantitative studies. The research field was mainly conducted in fields that were difficult to be conducted on actual subjects such as clinical technology and anatomical practice. Conclusion : VR research for prospective medical personnel can be trained in a reality-like environment, and for this, programs through environmental provision and practical level of visual and sensory interaction must be developed and operated.

A Comparative Study of Colour Effects on Cognitive Performance in Real-World and VR Environments.

This research explores the influence of colour on cognitive performance and intellectual abilities (i.e., logical and lateral thinking abilities and people’s attention to detail) in a conventional laboratory setting and an approximately identical virtual reality (VR) environment. Comparative experiments using psychological methods were carried out in both settings to explore the impact of immersive colour experience. This work builds on earlier studies that suggest that the VR environment enhances user experiences, with results evidencing that a considered approach to colour design can trigger a positive impact on user engagement. The experiments further evaluated the positive effects of immersive colour stimuli in VR by evaluating participants’ logical and lateral thinking abilities, as well as their attention to detail. Their response time and error rate when completing each psychometric test were recorded with different hue backgrounds in both environments. The data collected from participants reveal the differential impacts of colour between the reality setting using standard colour imaging displays and in an approximately identical VR environment. Analysis of the psychometric tests shows the differential influence of colours on logical and lateral thinking abilities and people’s attention to detail between the physical environment and the VR environment. Our findings add to the data demonstrating that a well-designed immersive colour experience in VR can trigger positive user engagement and, as explored in this study, improve cognitive performance. This again positions immersive colour experience as an important design tool to be fully considered in the creation of effective VR research and applications.

A cybersickness review: causes, strategies, and classification methods

Virtual reality (VR) and head-­mounted displays are continually gaining popularity in various fields such as education, military, entertainment, and health. Although such technologies provide a high sense of immersion, they can also trigger symptoms of discomfort. This condition is called cybersickness (CS) and is quite popular in recent virtual reality research. In this work we first present a review of the literature on theories of discomfort manifestations usually attributed to virtual reality environments. Following, we reviewed existing strategies aimed at minimizing CS problems and discussed how the CS measurement has been conducted based on subjective, bio­signal (or objective), and users profile data. We also describe and discuss related works that are aiming to mitigate cybersickness problems using deep and symbolic machine learning approaches. Although some works used methods to make deep learning explainable, they are not strongly affirmed by literature. For this reason in this work we argue that symbolic classifiers can be a good way to identify CS causes, once they possibilities human-­readability which is crucial for analyze the machine learning decision paths. In summary, from a total of 157 observed studies, 24 were excluded. Moreover, we believe that this work facilitates researchers to identify the leading causes for most discomfort situations in virtual reality environments, associate the most recommended strategies to minimize such discomfort, and explore different ways to conduct experiments involving machine learning to overcome cybersickness.

Virtual Reality Research: Design Virtual Education System for Epidemic (COVID-19) Knowledge to Public

Advances in information and communication technologies have created a range of new products and services for the well-being of society. Virtual Reality (VR) technology has shown enormous potential in educational, commercial, and medical fields. The recent COVID-19 outbreak highlights a poor global performance in communicating epidemic knowledge to the public. Considering the potential of VR, the research starts from analyzing how to use VR technology to improve public education in COVID-19. The research uses Virtual Storytelling Technology (VST) to promote enthusiasm in user participation. A Plot-based VR education system is proposed in order to provide an immersive, explorative, educational experiences. The system includes three primary modules: the Tutorial Module, the Preparation Module, and the Investigation Module. To remove any potential confusion in the user, the research aims to avoid extremely complicated medical professional content and uses interactive, entertainment methods to improve user participation. In order to evaluate the performance efficiency of the system, we conducted performance evaluations and a user study with 80 participants. Compared with traditional education, the experimental results show that the VR education system can used as an effective educational tool for epidemic (COVID-19) fundamental knowledge. The VR technology can assist government agencies and public organizations to increase public understanding of the spread the epidemic (COVID-19).

DiVRsify: Break the Cycle and Develop VR for Everyone

Virtual reality technology is biased. It excludes approximately 95% of the world’s population by being primarily designed for male, western, educated, industrial, rich, and democratic populations. This bias may be due to the lack of diversity in virtual reality researchers, research participants, developers, and end users, fueling a noninclusive research, development, and usability cycle. The objective of this article is to highlight the minimal virtual reality research involving understudied populations with respect to dimensions of diversity, such as gender, race, culture, ethnicity, age, disability, and neurodivergence. Specifically, we highlight numerous differences in virtual reality usability between underrepresented groups compared to commonly studied populations. These differences illustrate the lack of generalizability of prior virtual reality research. Lastly, we present a call to action with the aim that, over time, will break the cycle and enable virtual reality for everyone.
