However, questions remain about the optimal metrics for real-time data capture and the applicability of these solutions for enhancing user experiences. The present research examined a novel form of adaptive XR, called \"prediction-based attention computing\" (PbAC), which tailors simulations based on computational models of the brain and, thus, the dynamic sensorimotor processes theorised to underpin human perception and learning. Specifically, this study aimed to demonstrate whether PbAC can adaptively capture users' internal state predictions and modulate associated neuropsychological responses. To test this, we used an XR-based racquetball paradigm, in which participants were tasked with intercepting virtual balls that emerged from different starting locations. For PbAC conditions, in-situ eye tracking data assessments were utilised to index participant's prior beliefs and manipulate levels of expectedness (i.e., prediction error) on each trial. Various measures of predictive sensorimotor behaviour were then extracted and compared with data from probability-controlled and matched-order control conditions. Results showed that sensorimotor responses were affected by the expectedness of XR stimuli, and that clear, prediction-related biases emerged within PbAC conditions. The novel computing software also provoked marked surprisal responses on trials designed to elicit high levels of prediction error, and these surprisal effects were similar, or even greater than, those in our comparison conditions. Together, the findings provide proof of concept for PbAC and support its development within future research and technology innovations.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10055-025-01307-w.</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":"30 1","pages":"44"},"PeriodicalIF":5.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12855329/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146107489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Included were 22 children with cerebral palsy (CP) (age range 8-16 years; male/female: 13/9) and 24 children with typical development (TD) (age range 8-18 years; male/female: 10/14). Participants were instructed to stand still for 40s on two force plates while wearing a head-mounted display, which delivered the virtual environment. Postural balance was quantified via (1) the 95% prediction ellipse area, (2) the average centre of pressure (CoP) velocity, and (3) the CoP amplitude in anteroposterior and mediolateral direction. Additionally, self-reported instability and fear of falling was assessed using a 11-point numeric rating scale. Children with CP tended to exhibit increased median ellipse area, median anteroposterior amplitude, and median velocity from VR0 to VR10 and compared to children with TD, although differences were not statistically significant. Furthermore, median values of self-reported instability and fear of falling increased from VR0 to VR10 in both groups.

The aim of the study was to examine the effects of virtual reality on experimentally-induced pain (using cuff pressure algometry), as well as affective and perceptual responses, to moderate-intensity cycle ergometer exercise. A counterbalanced within-subjects design was employed and 19 healthy, pain-free adults completed 20-min exercise bouts at ventilatory threshold under two conditions: virtual reality and control. A one-way repeated measures ANOVA indicated a significant main effect of assessment for pressure detection threshold (<i>p</i> = .038), with higher pain thresholds observed immediately following each exercise bout when compared to baseline.

This study evaluates whether MR-based serious games with an integrated manikin can achieve learning outcomes comparable to the blended use of VR-based serious games and manikin-based training. Thirty-two fourth-semester students from Acıbadem Mehmet Ali Aydınlar University voluntarily participated and were randomly assigned to two groups: the VR + M Group (n = 16), trained with the blend of VR-based serious games and manikin-based simulation, and the MR Group (n = 16), trained with MR-based serious games. All participants completed a pretest before training. The VR + M Group underwent VR training and an exam, followed by manikin-based skills training and a hands-on exam. Their overall performance score was the average of the VR and manikin-based exam scores. The MR Group completed MR training and an MR-based exam. Both groups completed a posttest after training. Post-test scores improved significantly in both groups. A statistically significant difference was observed between the overall exam scores of the two groups, with the MR Group scoring higher on average. MR-based serious gaming, when integrated with manikin interaction, shows strong potential as an alternative training method for simulation-based Basic Life Support training.","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rest Frame (RF) is a set of virtual objects independent of the virtual environment (VE) that serve as fixed visual elements. Previous research has shown that using RF can reduce VR sickness. However, a constantly visible RF in the user’s field of view may obstruct objects in the VE and cause a decrease in the field of view, thereby impairing user presence. This study consists of two experiments aimed at exploring configurations of RF that minimize a decrease in presence while maximizing the reduction of VR sickness. In the first experiment, RF configurations with varying levels of opacity and density were tested during virtual travel. Eighteen VR users provide real-time responses regarding their level of VR sickness. After each of the three sessions, participants completed a Simulator Sickness Questionnaire (SSQ) to assess VR sickness and the Witmer & Singer Presence Questionnaire (WS) to evaluate presence. Results indicated that changes in RF density did not significantly affect either VR sickness or presence. The second experiment, planned based on the findings of the first, compared the most effective RF (opacity 0.4, density 0.4) identified in the initial experiment to a no-RF condition with twelve participants. Results confirmed that the most effective RF reduced VR sickness compared to the absence of RF. These findings highlight the importance of appropriate RF design in improving user comfort and suggest practical guidelines for developing immersive virtual environments.","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10055-025-01116-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147917005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared obstacle avoidance of physical objects with obstacle avoidance of closely matched 2D and 3D images of the physical objects. Participants were asked to reach towards a target position without colliding with obstacles of varying height that were placed in the movement path. Using a pre-test post-test design, we tested obstacle avoidance for 2D and 3D images of obstacles both before and after exposure to the physical obstacles. Consistent with previous findings, we found that participants initially underestimated the magnitude differences between the obstacles, but after exposure to the physical obstacles avoidance performance for the 3D images became similar to performance for the physical obstacles. No such change was found for 2D images. Our findings highlight the importance of disparity cues for naturalistic motor actions in personal space.

An alternative approach that helps to address these problems is VR-by-proxy, where teaching takes place within a VR environment that is controlled by one lecturer and broadcast to students online. This allows the content to be accessed without specialist equipment while still offering an immersive and interactive experience. Taking advantage of the enforced move to online learning during the COVID-19 pandemic, this study evaluates the implementation of a novel VR-by-proxy disease diagnostic laboratory VR simulation within an undergraduate life sciences course in a higher education setting. Student participants were randomly allocated into two groups: the test group, who took part in a VR-by-proxy lesson; and a control group, who worked with interactive online lab manual material. We assessed improvement in learning and enjoyment through questionnaires before and after these tasks and collected qualitative data on student attitudes towards VR through focus groups. Our results indicate that although there is no observable difference in learning outcomes between the two groups, students in the test group reported an improved learning experience, confidence and enjoyment of learning. In our focus groups, confidence was understood in two ways by participants: firstly, as 'understanding' of the various steps involved in conducting a quantitative polymerase chain reaction experiment and secondly as a more general 'familiarity' with the laboratory setting.
