Special Issue Information

Dear Colleagues,

In recent years, VR and AR technology have seen remarkable progress. Their fundamental problems, such as tracking and registration, have been solved almost entirely, and their applications for education, medicine, architecture, automobiles, advertising, entertainment, art and culture, etc. that researchers could only dream of 20 years ago have been put to practical use today. As some basic research has come to fruition, expectations for VR and AR have increased, and opportunities for advanced studies have also expanded. What should remote communications be when real-time three-dimensional reconstruction is realized and 5G high-speed communication becomes widespread? What information should be selected and presented to the user when advanced situational awareness becomes possible? What kind of short- and long-term effects on our body and mind will be exhibited by augmented vision or body modification? VR and AR are not just high-level computing environments but are becoming the next generation of social infrastructure. Various technologies, such as artificial intelligence, human augmentation, and brain science, are progressing and merging with VR and AR to become a driving force that puts VR and AR to even higher levels.

This Special Issue calls for interesting studies that will open up new horizons of VR and AR. In addition to research that has steadily improved existing issues, we welcome research papers that present new possibilities of VR and AR. Topics of interest include but are not limited to the following:

  • 360 video;
  • VR/AR applications;
  • Artificial intelligence/machine learning for VR/AR;
  • Brain science for VR/AR;

In this paper, we investigate the impact of avatar personalization on perceived emotions. Avatar embodiment is a crucial aspect of collaborative and social virtual reality (VR) systems. Previous research found that avatar appearance impacts the acceptability of the virtual body and changes users’ behavior. While virtual embodiment has been extensively investigated, we know very little about how embodiment affects users’ experienced emotions. In a user study (N = 40), we applied an autobiographical recall method to evoke happiness and investigated the influence of different types of avatar embodiment (personalized same-gender, personalized opposite-gender, non-personalized same-gender, and non-personalized opposite-gender) on participants’ perceived emotion. We recorded both self-reported assessments and physiological data to observe participants’ emotional responses resulting from the emotions elicited by the use of different avatars. We found significant differences in happiness with the personalized same-gender avatar and the personalized opposite-gender avatar. We provide empirical evidence, demonstrating the influence of avatar personalization on emotions in VR. We conclude with recommendations for users and designers of virtual reality experiences.

In this paper, we conducted descriptive quantitative research on the assessment of virtual reality (VR) technologies in higher education in the countries of the Pacific Alliance (PA). Specifically, differences between PA countries in terms of the above perceptions were identified and the behavior of the gender and knowledge area gaps in each of them was analyzed. A validated quantitative questionnaire was used for this purpose. As a result, we found that PA professors express high ratings of VR but point out strong disadvantages regarding its use in lectures; in addition, they have low self-concept of their digital competence. In this regard, it was identified that there are notable differences among the PA countries. Mexico is the country with the most marked gender gaps, while Chile has strong gaps by areas of knowledge. We give some recommendations towards favoring a homogeneous process of integration of VR in higher education in the PA countries. Full article

The goal of the current study was to investigate the effects of a virtual reality (VR) simulation of Anne Frank’s hiding place on learning. In a 2 × 2 experiment, 132 middle school students learned about the living conditions of Anne Frank, a girl of Jewish heritage during the Second World War, through desktop VR (DVR) and head-mounted display VR (HMD-VR) (media conditions). Approximately half of each group engaged in an explorative vs. an expository learning approach (method condition). The exposition group received instructions on how to explore the hiding place stepwise, whereas the exploration group experienced it autonomously. Next to the main effects of media and methods, the mediating effects of the learning process variables of presence and flow and the moderating effects of contextual variables (e.g., prior technical knowledge) have been analyzed. The results revealed that the HMD-VR led to significantly improved evaluation, and—even if not statistically significant—perspective-taking in Anne, but less knowledge gain compared to DVR. Further results showed that adding instructions and segmentation within the exposition group led to significantly increased knowledge gain compared to the exploration group. For perspective-taking and evaluation, no differences were detected. A significant interaction between media and methods was not found. No moderating effects by contextual variables but mediating effects were observed: For example, the feeling of presence within VR can fully explain the relationships between media and learning. These results support the view that learning processes are crucial for learning in VR and that studies neglecting these learning processes may be confounded. Hence, the results pointed out that media comparison studies are limited because they do not consider the complex interaction structures of media, instructional methods, learning processes, and contextual variables.

A variety of evaluation methods for user interfaces (UI) exist such as usability testing, cognitive walkthrough, and heuristic evaluation. However, UIs such as guidance systems at transit hubs must be evaluated in their intended application field to allow the effective and valid identification of usability flaws. However, what if evaluations are not feasible in real environments, or laboratorial conditions cannot be ensured? Based on adapted heuristics, in the present study, the method of heuristic evaluation is combined with immersive Virtual Reality (VR) for the identification of usability flaws of dynamic guidance systems (DGS) at transit hubs. The study involved usability evaluations of nine DGS concepts using the newly proposed method. The results show that compared to computer-based heuristic evaluations, the use of immersive VR led to the identification of an increased amount of “severe” usability flaws as well as overall usability flaws. Within a qualitative assessment, immersive VR is validated as a suitable tool for conducting heuristic evaluations involving significant advantages such as the creation of realistic experiences in laboratorial conditions. Future work seeks to further prove the suitability of using immersive VR for heuristic evaluations and compare the proposed method to other evaluative methods. Full article

Rhythm games are known for their engaging gameplay and have gained renewed popularity with the adoption of virtual reality (VR) technology. While VR rhythm games have achieved commercial success, there is a lack of research on how and why they are engaging, and the connection between that engagement and immersion or presence. This study aims to understand how the design of two popular VR rhythm games, Beat Saber and Ragnarock, leverages presence to immerse players. Through a mixed-methods approach, utilising the Multimodal Presence Scale and a thematic analysis of open-ended questions, we discovered four mentalities which characterise user experiences: action, game, story and musical. We discuss how these mentalities can mediate presence and immersion, suggesting considerations for how designers can leverage this mapping for similar or related games. Full article

Virtual Reality (VR) provides great opportunities for police officers to train decision-making and acting (DMA) in cognitively demanding and stressful situations. This paper presents a summary of findings from a three-year project, including requirements collected from experienced police trainers and industry experts, and quantitative and qualitative results of human factor studies and field trials. Findings include advantages of VR training such as the possibility to safely train high-risk situations in controllable and reproducible training environments, include a variety of avatars that would be difficult to use in real-life training (e.g., vulnerable populations or animals) and handle dangerous equipment (e.g., explosives) but also highlight challenges such as tracking, locomotion and intelligent virtual agents. The importance of strong alignment between training didactics and technical possibilities is highlighted and potential solutions presented. Furthermore training outcomes are transferable to real-world police duties and may apply to other domains that would benefit from simulation-based training. Full article

Chemical phenomena are only observable on a macroscopic level, whereas they are explained by entities on a non-visible level. Students often demonstrate limited ability to link these different levels. Augmented reality (AR) offers the possibility to increase contiguity by embedding virtual models into hands-on experiments. Therefore, this paper presents a pre- and post-test study investigating how learning and cognitive load are influenced by AR during hands-on experiments. Three comparison groups (AR, animation and filmstrip), with a total of N = 104 German secondary school students, conducted and explained two hands-on experiments. Whereas the AR group was allowed to use an AR app showing virtual models of the processes on the submicroscopic level during the experiments, the two other groups were provided with the same dynamic or static models after experimenting. Results indicate no significant learning gain for the AR group in contrast to the two other groups. The perceived intrinsic cognitive load was higher for the AR group in both experiments as well as the extraneous load in the second experiment. It can be concluded that AR could not unleash its theoretically derived potential in the present study. Full article

Mid-air collision is one of the top safety risks in general aviation. This study addresses the description and experimental assessment of multimodal Augmented Reality (AR) applications for training of traffic procedures in accordance with Visual Flight Rules (VFR). AR has the potential to complement the conventional flight instruction by bridging the gap between theory and practice, and by releasing students’ time and performance pressure associated with a limited simulator time. However, it is critical to assess the impact of AR in the specific domain and to identify any potential negative learning transfer. Multimodal AR applications were developed to address various areas of training: guidance and feedback for the correct scanning pattern, estimation if an encountering traffic is on collision course and application of the relevant rules. The AR applications also provided performance feedback for collision detection, avoidance and priority decisions. The experimental assessment was conducted with 59 trainees (28 women, 31 men) assigned to an experimental group (AR training) and a control group (simulator training). The results of tests without AR in the flight simulator show that the group that trained with AR obtained similar levels of performance like the control group. There was no negative training effect of AR on trainees’ performance, workload, situational awareness, emotion nor motivation. After training the tasks were perceived as less challenging, the accuracy of collision detection has improved, and the trainees reported less intense negative emotions and fear of failure. Furthermore, a scanning pattern test in AR showed that the AR training group performed the scanning pattern significantly better than the control group. In addition, there was a significant gender effect on emotion, motivation and preferences for AR features, but not on performance. Women liked the voice interaction with AR and the compass hologram more than men. Men liked the traffic holograms and the AR projection field more than women. These results are important because they provide experimental evidence for the benefits of multimodal AR applications that could be used complementary to the flight simulator training. Full article

Teaching and learning theoretical subjects, such as History, although important, is considered by many students to be non-appealing. Alternative teaching approaches include the use of educational games and augmented reality (AR) applications, or more recently, AR educational games. Such games are considered to increase students’ interest for the subject and lead to better learning outcomes. However, studies about the use of AR educational games in the classroom are sparse and further research is necessary. In this article, we present an AR-enhanced educational game for teaching History (Greek Mythology) to 3rd grade Primary school students in Greece. The game, called “AR The Gods of Olympus” consists of three mini games: an AR game with the gods/goddesses of Olympus using narration; a memory game with cards depicting the gods and their symbols; and a quiz game. In order to study the effectiveness of the game and students’ experience and perceptions on it, a study was carried out with primary school students that used the game in classroom. The study utilized a pre-/post-test design, a brief questionnaire based on the MEEGA+ model for evaluating educational games, and observation of students during game playing. Students’ performance was improved after playing the game but the difference was not statistically significant, while the game was positively perceived by students. Especially the AR mini game raised students’ interest and as the students themselves stated helped them “learn while playing”. Full article

The following study addresses, from a design perspective, narrative visualization using augmented reality (AR) in real physical spaces, and specifically in spaces with no semantic relation with the represented data. We intend to identify the aspects augmented reality adds, as narrative possibilities, to data visualization. Particularly, we seek to identify the aspects augmented reality introduces regarding the three dimensions of narrative visualization—view, focus and sequence. For this purpose, we adopted a comparative analysis of a set of fifty case studies, specifically, narrative visualizations using augmented reality from a journalistic scope, where narrative is a key feature. Despite the strong explanatory character that characterizes the set of analyzed cases, which sometimes limits the user’s agency, there is a strong interactive factor. It was found that augmented reality can expand the narrative possibilities in the three dimensions mentioned—view, focus and sequence—but especially regarding visual strategies where simulation plays an essential role. As a visual strategy, simulation can provide the context for communication or be the object of communication itself, as a replica. Full article

Augmented Reality (AR) solutions are emerging in multiple scenarios of application as Industry 4.0 takes shape. In particular, for remote collaboration, flexible mechanisms such as authoring tools can be used to generate instructions and assist human operators as they experience increased complexity in their daily tasks. In addition to the traditional handicap of ensuring instructions can be intuitively created without having to understand complicated AR concepts, another relevant topic is the fact that the quality of said instructions is not properly analyzed prior to the tools being evaluated. This means that the characteristics of the visual content are not adequately assessed beforehand. Hence, it is essential to be aware of the cognitive workload associated with AR instructions to assert if they can be easily understood and accepted before being deployed in real-world scenarios. To address this, we focused on AR during sessions of remote guidance. Based on a participatory process with domain experts from the industry sector, a prototype for creating AR-based instructions was developed, and a user study with two parts was conducted: (1) first, a set of step-by-step instructions was produced, and their visual characteristics were evaluated by 129 participants based on a set of relevant dimensions; (2) afterward, these instructions were used by nine participants to understand if they could be used to assist on-site collaborators during real-life remote maintenance tasks. The results suggest that the AR instructions offer low visual complexity and considerable visual impact, clarity, and directed focus, thus improving situational understanding and promoting task resolution.

Background: Chemistry and biology students often have difficulty understanding molecular structures. Sonification (the rendition of data into non-speech sounds that convey information) can be used to support molecular understanding by complementing scientific visualization. A proper sonification design is important for its effective educational use. This paper describes a participatory design (PD) approach to designing and developing the sonification of a molecular structure model to be used in an educational setting. Methods: Biology, music, and computer science students and specialists designed a sonification of a model of an insulin molecule, following Spinuzzi’s PD methodology and involving evolutionary prototyping. The sonification was developed using open-source software tools used in digital music composition. Results and Conclusions: We tested our sonification played on a virtual reality headset with 15 computer science students. Questionnaire and observational results showed that multidisciplinary PD was useful and effective for developing an educational scientific sonification. PD allowed for speeding up and improving our sonification design and development. Making a usable (effective, efficient, and pleasant to use) sonification of molecular information requires the multidisciplinary participation of people with music, computer science, and molecular biology backgrounds.

Computational fluid dynamics (CFD) are being used more and more in the industry to understand and optimize processes such as fluid flows. At the same time, tools such as augmented reality (AR) are becoming increasingly important with the realization of Industry 5.0 to make data and processes more tangible. Placing the two together paves the way for a new method of active learning and also for an interesting and engaging way of presenting industry processes. It also enables students to reinforce their understanding of the fundamental concepts of fluid dynamics in an interactive way. However, this is not really being utilized yet. For this reason, in this paper, we aim to combine these two powerful tools. Furthermore, we present the framework of a modular open-source library for scientific visualization of fluid flow “OpenVisFlow” which simplifies the creation of such applications and enables seamless visualization without other software by allowing users to integrate the visualization step into the simulation code. Using this framework and the open-source extension AR-Core, we show how a new markerless visualization tool can be implemented. Full article

Researchers have proposed a wide range of categorization schemes in order to characterize the space of VR locomotion techniques. In a previous work, a typology of VR locomotion techniques was proposed, introducing motion-based, roomscale-based, controller-based, and teleportation-based types of VR locomotion. The fact that (i) the proposed typology is used widely and makes a significant research impact in the field and (ii) the VR locomotion field is a considerably active research field, creates the need for this typology to be up-to-date and valid. Therefore, the present study builds on this previous work, and the typology’s consistency is investigated through a systematic literature review. Altogether, 42 articles were included in this literature review, eliciting 80 instances of 10 VR locomotion techniques. The results indicated that current typology cannot cover teleportation-based techniques enabled by motion (e.g., gestures and gazes). Therefore, the typology was updated, and a new type was added: “motion-based teleporting.” Full article

Visual stimuli are frequently used to improve memory, language learning or perception, and understanding of metacognitive processes. However, in virtual reality (VR), there are few systematically and empirically derived databases. This paper proposes the first collection of virtual objects based on empirical evaluation for inter-and transcultural encounters between English- and German-speaking learners. We used explicit and implicit measurement methods to identify cultural associations and the degree of stereotypical perception for each virtual stimuli (n = 293) through two online studies, including native German and English-speaking participants. The analysis resulted in a final well-describable database of 128 objects (called InteractionSuitcase). In future applications, the objects can be used as a great interaction or conversation asset and behavioral measurement tool in social VR applications, especially in the field of foreign language education. For example, encounters can use the objects to describe their culture, or teachers can intuitively assess stereotyped attitudes of the encounters. Full article

Virtual reality (VR) is an emerging technology with a variety of potential benefits for vocational training. Therefore, this paper presents a VR training based on the highly validated 4C/ID model to train vocational competencies in the field of vehicle painting. The following 4C/ID components were designed using the associated 10 step approach: learning tasks, supportive information, procedural information, and part-task practice. The paper describes the instructional design process including an elaborated blueprint for a VR training application for aspiring vehicle painters. We explain the model’s principles and features and their suitability for designing a VR vocational training that fosters integrated competence acquisition. Following the methodology of design-based research, several research methods (e.g., a target group analysis) and the ongoing development of prototypes enabled agile process structures. Results indicate that the 4C/ID model and the 10 step approach promote the instructional design process using VR in vocational training. Implementation and methodological issues that arose during the design process (e.g., limited time within VR) are adequately discussed in the article. Full article

This paper presents quantitative research on the perception of the didactic use of virtual reality by university professors in Colombia, with special attention to the differences according to their area of knowledge, as the main variable, and gender and digital generation, as secondary variables. The study involved 204 professors from different Colombian universities. As an instrument, a survey designed for this purpose was used with four scales that were used to measure, on a Likert scale, different dimensions involving the participants’ perception of the use of virtual reality in the classroom. The answers were analyzed statistically and the differences in the perceptions have been identified by means of parametric statistical tests according to the following: (i) area of knowledge, (ii) gender, (iii) digital generation of the participants. The results showed that the participants expressed high valuations of virtual reality, despite having intermediate or low levels of digital competence. Gaps were identified in terms of area of knowledge, gender, and digital generation (digital natives or immigrants) with respect to opinions of virtual reality and digital competence. The highest valuations of virtual reality are given by professors of Humanities, and by digital natives. It is suggested that Colombian universities implement training plans on digital competence for professors and that these plans be aimed at strengthening knowledge of virtual reality. Full article

Immersive virtual reality (iVR) has gained considerable attention recently with increasing affordability and accessibility of the hardware. iVR applications for older adults present tremendous potential for diverse interventions and innovations. The iVR literature, however, provides a limited understanding of guiding design considerations and evaluations pertaining to user experience (UX). To address this gap, we present a state-of-the-art scoping review of literature on iVR applications developed for older adults over 65 years. We performed a search in ACM Digital Library, IEEE Xplore, Scopus, and PubMed (1 January 2010–15 December 2019) and found 36 out of 3874 papers met the inclusion criteria. We identified 10 distinct sets of design considerations that guided target users and physical configuration, hardware use, and software design. Most studies carried episodic UX where only 2 captured anticipated UX and 7 measured longitudinal experiences. We discuss the interplay between our findings and future directions to design effective, safe, and engaging iVR applications for older adults. Full article

Augmented reality (AR) head-mounted displays (HMDs) are an increasingly popular technology. For surgical applications, the use of AR HMDs to display medical images or models may reduce invasiveness and improve task performance by enhancing understanding of the underlying anatomy. This technology may be particularly beneficial in open surgeries and interventional procedures for which the use of endoscopes, microscopes, or other visualization tools is insufficient or infeasible. While the capabilities of AR HMDs are promising, their usability for surgery is not well-defined. This review identifies current trends in the literature, including device types, surgical specialties, and reporting of user demographics, and provides a description of usability assessments of AR HMDs for open surgeries and interventional procedures. Assessments applied to other extended reality technologies are included to identify additional usability assessments for consideration when assessing AR HMDs. The PubMed, Web of Science, and EMBASE databases were searched through September 2022 for relevant articles that described user studies. User assessments most often addressed task performance. However, objective measurements of cognitive, visual, and physical loads, known to affect task performance and the occurrence of adverse events, were limited. There was also incomplete reporting of user demographics. This review reveals knowledge and methodology gaps for usability of AR HMDs and demonstrates the potential impact of future usability research. Full article
