The impact of different transitions between two virtual reality (VR) environments is still an open research question, and related work often serves only an isolated view on different techniques, i.e., with low ecological validity. The purpose of this study was to start closing this gap and evaluate the impact of six transitions while the user is solving a task that keeps them engaged. Therefore, we first propose a suitable and reproducible task design. Then we evaluate the six transitions in a user study. The results show that in contrast to prior work, the users preferred a short and efficient transition against a transition that was designed to achieve higher interactivity and continuity but was perceived as more cumbersome to use. © 2023 Owner/Author.

virtual reality (VR) is often used in small physical environments, requiring users to remain aware of their environment to avoid injury or damage. However, this can reduce their spatial presence in VR. Previous work and theory lack an account of how the physical environment (PE) affects spatial presence. To address this gap, we investigated the effect on spatial presence of (1) the degree of spatial knowledge of the PE and (2) knowledge of and (3) collisions with obstacles in the PE. Estimates from Bayesian regression models suggest that limiting spatial knowledge of the PE increases spatial presence initially but amplifies the detrimental effect of obstacle collisions. Repeatedly avoiding obstacles further decreases spatial presence, but removing them from the user's path yields a partial recovery. Our work contributes empirical evidence to theories of spatial presence formation and highlights the need to consider the physical environment when designing for presence in VR. © 2025 Copyright held by the owner/author(s).

While virtual reality (VR) games offer immersive experiences, prolonged improper head posture during VR gaming sessions can cause neck discomfort and injuries. To address this issue, we prototyped a framework to detect instances of improper head posture and apply various visual interventions to correct them. After assessing the prototype's usability in a co-design workshop with participants experienced in VR design and kinesiology, we refined the interventions in two main directions - using explicit visual indicators or employing implicit background changes. The refined interventions were subsequently tested in a controlled experiment involving a target selection task. The study results demonstrate that the interventions effectively helped participants maintain better head posture during VR gameplay compared to the control condition. © 2025 Copyright held by the owner/author(s).

Fluid human social interaction demands a complex exchange of verbal and non-verbal signals. Effectively interpreting and responding to these signals requires timely visual attention to relevant stimuli and coordination of appropriate motor responses. Differences in social interaction are a key part of the criteria for autism, but such differences are also frequently found in conjunction with differences in gaze and gross motor behavior, as well as physiological arousal. This finding suggests these basic functions may contribute to atypical social interactions, especially in highly dynamic situations. Our study uses a virtual reality pattern completion video game with solo and cooperative conditions to measure gaze, motor, and physiological responses to social and non-social stimuli within the virtual environment. In a population of 11 autistic and 16 non-autistic young adults, we measured gaze behavior and pupil diameter as an index of physiological arousal and two different perception-action sequences that occur in the pattern completion task. Compared to non-autistic players, the autistic players had longer fixation duration times in cooperative condition during looks to the most socially dynamic region of the virtual environment. We also observed differences across group and condition in a perception action sequence that demanded visually localizing a block and placing it onto a specific location to complete the sequence. Pupil arousal responses were triggered on the same block placement event and revealed significantly larger arousal changes for autistic players in the cooperative condition. These findings demonstrate specific effects of social presence on fundamental behaviors that comprise social interaction and can be measured, and eventually manipulated, in virtual reality. © 2023 IEEE.

People with health anxiety often experience feelings of nervousness or panic while in high-stress environments. While various techniques such as aromatherapy, and therapeutic video games have been shown to be effective in reducing anxiety, few studies have explored the use of a combination of these techniques in a multisensory approach. In this paper, we propose "Lullaland", a therapeutic virtual reality game that incorporates a wireless diffuser to provide an immersive, multisensory experience designed to help reduce anxiety in medical waiting rooms. © 2023 Owner/Author.

Integrating novel technologies in education, namely technology-enhanced learning (TEL), is broadly discussed in educational and technology development areas. It is understood that educators can improve their comprehension of each student's learning processes using gathered data and provide more personalized content using technology. This work proposes a novel solution to automating getting data from interactions executed in virtual reality. This system offers a user-friendly interface allowing educators to create and share multimedia content in the game, collect data to provide insights about the users' behavior based on his interactions with the system, and provide an analytic tool for feedback and future analysis. The system's design discusses the main lessons learned by analyzing the theoretical concepts, functional and non-functional requirements, and the architecture proposal. © 2023 ACM.

This article describes a pilot project studying the use of virtual reality (VR) in visualization of cruise ship interiors. The research was conducted as part of a research project targeting at sustainable shipbuilding methods. It was directly connected to an ongoing cruise ship project, so the applicability of the proposed technologies to the actual production process could be verified. The goal was to use VR reviews instead of or in addition to constructing physical mock-up sections of the ship interiors, and to gain improvements in sustainability and stakeholder communication. Four enterprises participated in the pilot, in which number of virtual 3D models were created, and presented to customers in VR. Results from both the construction companies and customers indicate that in the VR environment helps reviewers evaluate the designs better than using traditional methods, and that material savings are possible. However, it was also discovered that the rendering capabilities of the software environment used in the study do not enable such realism that would be required in certain types of reviews. The results suggest that VR can be an efficient tool for design reviews, and the stakeholder groups are willing to take it into regular use. © 2024, The Authors. All rights reserved.

Due to the pandemic, we have become more reliant on digital technologies in every aspect of our lives. This has led to an increasing interest in teaching and training students and employees using immersive technologies and increasing multicultural learning and digital literacies in schools. This research-creation Ph.D. study aims to advance the understanding of the impact of interactive virtual reality non-fiction (VRNF) narratives as experiential learning tools to promote global citizenship education and to counter radicalization among high school and university students. The researcher will explore the effect of interactive VRNF narratives on open-mindedness trait and intercultural communication competence as moderators for multicultural learning in VR. This study also seeks to design and evaluate a VRNF narrative based on educators'/creators' feedback and contribution. This narrative will reflect a personal journey of multicultural learning in the Canadian context. A mixed method approach will be used: Delphi interview method and quasi-experimental study to examine the effects of interactivity and immersion on narrative transportation and user engagement. Results and recommendations will then be reported for further research and implementation. © 2023 IEEE.

Personal lifelog data collections are becoming more common as a memory aid, as well as for analytical tasks, such as health and fitness analysis. Due to the multimodal and personal nature of lifelog data, interactive multimedia retrieval approaches are required to facilitate flexible and iterative query formulation and result exploration for retrieval and analysis. In recent years, novel user interface modalities have emerged, that allow new ways for users to interact with a retrieval system. virtual reality, one such new modality, provides advantages as well as challenges for interactive multimedia retrieval in comparison to conventional desktop-based interfaces. This paper describes a novel desktop-virtual reality hybrid system participating in the Lifelog Search Challenge 2023. The system, which is based on the components of the vitrivr stack, is described with a focus on query formulation in the web-based desktop user interface vitrivr-ng, and result exploration in the virtual reality-based vitrivr-VR. © 2023 Owner/Author.

Augmented reality (AR) technology gives real and computerized elements that appear to coexist in real space. It makes users feel all three senses: smelling, hearing, and touch of the human body. virtual reality (VR) is technology comprising interactive computer simulations that create the impression of being completely or partially immersed. It is a strong human-computer interface that merges computer animation, image analysis, pattern identification, artificial intelligence, networking, and other technologies. This paper provides an overview of VR and AR technologies. It highlights tracking, interaction techniques, and display technology as key AR technologies, whereas immersive, semi-immersive, and non-immersive are the leading technologies of VR. It discusses the various use cases of VR and AR. © 2023 IEEE.
