Sex differences in vocal behavior in virtual rooms compared to real rooms.

This study investigates speech production under various room acoustic conditions in virtual environments, by comparing vocal behavior and the subjective experience of speaking in four real rooms and their audio-visual virtual replicas. Sex differences were explored. Males and females (N = 13) adjusted their voice levels similarly to room acoustic changes in the real rooms, but only males did so in the virtual rooms. Females, however, rated the visual virtual environment as more realistic compared to males. This suggests a discrepancy between sexes regarding the experience of realism in a virtual environment and changes in objective behavioral measures such as voice level.

Oscillatory correlates of threat imminence during virtual navigation.

The Predatory Imminence Continuum Theory proposes that defensive behaviors depend on the proximity of a threat. While the neural mechanisms underlying this proposal are well studied in animal models, it remains poorly understood in humans. To address this issue, we recorded EEG from 24 (15 female) young adults engaged in a first-person virtual reality Risk-Reward interaction task. On each trial, participants were placed in a virtual room and presented with either a threat or reward conditioned stimulus (CS) in the same room location (proximal) or different room location (distal). Behaviorally, all participants learned to avoid the threat-CS, with most using the optimal behavior to actively avoid the proximal threat-CS (88% accuracy) and passively avoid the distal threat-CS (69% accuracy). Similarly, participants learned to actively approach the distal reward-CS (82% accuracy) and to remain passive to the proximal reward-CS (72% accuracy). At an electrophysiological level, we observed a general increase in theta power (4-8 Hz) over the right posterior channel P8 across all conditions, with the proximal threat-CS evoking the largest theta response. By contrast, distal cues induced two bursts of gamma (30-60 Hz) power over midline-parietal channel Pz (200 msec post-cue) and right frontal channel Fp2 (300 msec post-cue). Interestingly, the first burst of gamma power was sensitive to the distal threat-CS and the second burst at channel Fp2 was sensitive to the distal reward-CS. Together, these findings demonstrate that oscillatory processes differentiate between the spatial proximity information during threat and reward encoding, likely optimizing the selection of the appropriate behavioral response.

Stylish virtual tour: exploring fashion’s influence on attitude and satisfaction in VR tourism

PurposeThis study aims to investigate the influence of different virtual fashion styles on attitude and satisfaction within virtual reality (VR) tourism experiences. The investigation considers the mediating effect of perceived attractiveness, popularity, novelty and weirdness, as well as the moderating role of self-congruence with avatar clothing and the desire for unique products.Design/methodology/approachThis research uses a quantitative experimental approach. Initially, a three-step pilot study (N = 201) was conducted to select avatar fashion styles for the main investigation. In the primary study, participants (N = 326) engaged with one out of four fashion style conditions to select attire for their avatars and then completed a self-administered survey. Data analysis involved paired-sample t-tests, multivariate analysis of variance and Hayes’ PROCESS Models.FindingsThe results show that presenting fantasy avatar fashion styles leads to a decrease in perceived attractiveness and popularity, while concurrently increasing perceptions of novelty and weirdness which in turn exert a negative influence on attitude and satisfaction with the virtual fitting room (VFR). However, these relationships change when considering the moderating role of self-congruence with avatar clothing and the desire for unique products.Practical implicationsVR tourism experience providers and designers can use research findings to bolster positive attitude and enhance satisfaction with VFR; an important first step that strongly affects the rest of the VR tourist journey.Originality/valueThis study contributes to tourism research by exploring the intersection of immersive technologies and virtual fashion. It emphasizes the enhancement of critical touchpoints like the VFR, moving beyond a sole focus on VR adoption, to improve the overall virtual tourist experience.

Changes in spatial self-consciousness elicit grid cell–like representation in the entorhinal cortex

Grid cells in the entorhinal cortex (EC) encode an individual's location in space, integrating both environmental and multisensory bodily cues. Notably, body-derived signals are also primary signals for the sense of self. While studies have demonstrated that continuous application of visuo-tactile bodily stimuli can induce perceptual shifts in self-location, it remains unexplored whether these illusory changes suffice to trigger grid cell-like representation (GCLR) within the EC, and how this compares to GCLR during conventional virtual navigation. To address this, we systematically induced illusory drifts in self-location toward controlled directions using visuo-tactile bodily stimulation, while maintaining the subjects' visual viewpoint fixed (absent conventional virtual navigation). Subsequently, we evaluated the corresponding GCLR in the EC through functional MRI analysis. Our results reveal that illusory changes in perceived self-location (independent of changes in environmental navigation cues) can indeed evoke entorhinal GCLR, correlating in strength with the magnitude of perceived self-location, and characterized by similar grid orientation as during conventional virtual navigation in the same virtual room. These data demonstrate that the same grid-like representation is recruited when navigating based on environmental, mainly visual cues, or when experiencing illusory forward drifts in self-location, driven by perceptual multisensory bodily cues.

Exploration and practice of multi-school co-construction of regional virtual teaching and research room for building electrical and intelligent specialty

To meet the needs of professional development promotion through cross-university collaborative construction in the era of Internet+, a new model of cross-university teaching and research organization is proposed by constructing a regional virtual teaching and research room for remote teaching and research activities among grassroots teaching organizations of different universities, utilizing modern information technology. Led by the national first-class specialty construction site of Building Electrical and Intelligent Specialty at Zhengzhou University of Light Industry, a cross-university regional virtual teaching and research room for this specialty is established in collaboration with other universities offering the same specialty in Henan province. This paper outlines the efficient and stable operation mechanism for the regional virtual teaching and research room’s multi-university collaborative construction and explores the co-construction path for cross-university regional virtual teaching and research rooms. A high-quality resource sharing platform for multi-university collaborative construction is built within the regional virtual teaching and research room, enabling intercollegiate high-quality resource and outstanding teaching team interconnection, co-construction, and sharing. This approach aims to fully leverage the distinctive features and advantages of the Building Electrical and Intelligent Specialty in each university in the region, promote cooperative development and interdisciplinary integration among partnering universities, and improve the quality of talent cultivation.

Enhancing Well-Being: A Comparative Study of Virtual Reality Chromotherapy Rooms with Static, Dynamic, and Empty Environments.

Chromotherapy rooms (CRs) are physical spaces with colored lights able to enhance an individual's mood, well-being, and, in the long term, their health. Virtual reality technology can be used to implement CR (VRCRs) and provide higher flexibility at lower costs. However, existing VRCRs are limited to a few use cases, and they do not fully explore the potential and pitfalls of the technology. This work contributes by comparing three VRCR designs: empty, static, and dynamic. Empty is just a void but a blue-colored environment. Static adds static abstract graphics (flowers and sea texture), and dynamic adds dynamic elements (animated star particle systems, fractals, and ocean flow). All conditions include relaxing low-beta and ocean sounds. We conducted a between-subject experiment (n = 30) with the three conditions. Subjects compiled a self-perceived questionnaire and a mathematical stress test before and after the VRCR experience. The results demonstrated that the dynamic condition provided a higher sense of presence, while the self-perceived stress level was insignificant. Dynamic VR conditions are perceived as having a shorter duration, and participants declared that they felt more involved and engaged than in the other conditions. Overall, the study demonstrated that VRCRs have a non-trivial behavior and need further study of their design, especially considering their role in a future where VR will be an everyday working interface.

Software development metrics: to VR or not to VR

ContextCurrent data visualization interfaces predominantly rely on 2-D screens. However, the emergence of virtual reality (VR) devices capable of immersive data visualization has sparked interest in exploring their suitability for visualizing software development data. Despite this, there is a lack of detailed investigation into the effectiveness of VR devices specifically for interacting with software development data visualizations.ObjectiveOur objective is to investigate the following question: “How do VR devices compare to traditional screens in visualizing data about software development?” Specifically, we aim to assess the accuracy of conclusions derived from exploring visualizations for understanding the software development process, as well as the time required to reach these conclusions.MethodIn our controlled experiment, we recruited N=32 volunteers with diverse backgrounds. Participants interacted with similar data visualizations in both VR and traditional screen environments. For the traditional screen setup, we utilized a commercially available set of interactive dashboards based on Kibana, commonly used by Bitergia customers for data insights. In the VR environment, we designed a set of visualizations, tailored to provide an equivalent dataset within a virtual room. Participants answered questions related to software evolution processes, specifically code review and issue tracking, in both VR and traditional screen environments, for two projects. We conducted statistical analyses to compare the correctness of their answers and the time taken for each question.ResultsOur findings indicate that the correctness of answers in both environments is comparable. Regarding time spent, we observed similar durations, except for complex questions that required examining multiple interconnected visualizations. In such cases, participants in the VR environment were able to answer questions more quickly.ConclusionBased on our results, we conclude that VR immersion can be equally effective as traditional screen setups for understanding software development processes through visualization of relevant metrics in most scenarios. Moreover, VR may offer advantages in comprehending complex tasks that require navigating through multiple interconnected visualizations. However, further experimentation is necessary to validate and reinforce these conclusions.
