Psychological measures (i.e., EDI-2) were assessed at three points: pre-treatment, post-treatment, and at 1-month follow-up. Behavioral measures (i.e., BMI) were evaluated at 6 different time points, instead (i.e., pre-treatment, post-treatment, 3, 6, 9, and 12 months from the discharge date). The VR treatment was more effective in improving the EDI subscales EDI-DT (i.e., drive for thinness) and EDI-BU (i.e., binging-purging behaviors). In particular, patients in the VR condition showed a reduced EDI-BU score at 1-month follow-up and post-test in comparison to the pre-test, as well as a lower EDI-DT score at 1-month follow-up compared to the pre-test. Conversely, no significant changes were noted in the IP group for either subscale. Regarding the behavioral measures, the group undergoing the VR condition reported the maintenance of the BMI in the long term compared to the IP. Specifically, in the VR group BMI decreased from the pre- to post-test, and from the pre-test to the 12-month follow-up. In the IP group, BMI improved from the pre- to the post-test, and from the pre-test to the 12-month follow-up. However, a relapse pattern was observed in the IP condition during the follow-up period, with a significant BMI increase from the post-test to the 9-month follow-up, from the 3 to the 9-month follow-up, from the 6 to the 9-month follow-up, and a decrease of BMI between the 9 and the 12-month follow-up. In conclusion, these results suggest that integrating VR treatment into the care of individuals with BN could enhance both immediate and sustained treatment outcomes.

Particularly in educational settings, IVR holds the potential to augment accessibility and engagement in learning. However, one pivotal aspect lies in assessing the learners' acceptance of such environments to ensure optimal and effective utilization of these technologies. This paper delves into the Didascalia Virtual-ClassRoom usability testing —an immersive IVR environment tailored for pre-service secondary school teachers. The platform transports users into a simulated classroom, where they are invited to play the role of a teacher. During the simulation, three scenarios are recreated, reproducing disruptive behaviours commonly faced in real classrooms. 84 participants (28 teachers and 56 pre-service teachers) engaged in decision-making to manage the classroom climate influenced by the simulated situations. To collect data, we used a questionnaire based on the Technology Acceptance Model (TAM) to assess and gauge users' inclinations and attitudes towards embracing the technology in question. To gain deeper insights into the user experience, participants were further invited to participate in semi-structured interviews, offering reflections and suggestions for potential enhancements. The evaluation process encompassed the perceived usefulness of the Didascalia Virtual-ClassRoom, shedding light on factors that could either facilitate or impede the adoption of this platform to enhance classroom management competence. The participants' perspectives serve as a valuable foundation for refining the tool's functionality, and their feedback fuels recommendations for its seamless integration into initial teacher training programs.</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":"15 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140147235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the omnipresence of cyberattacks, victims can hardly distance themselves psychologically, thus experience an intrusion in almost all areas of life. The perpetrators, on the other hand, feel the consequences of their actions even less in cyberspace. However, there is a gap between the need and the existence of innovative prevention programs tied to the digital reality of the target group and the treatment of essential aspects of psychological distance. This article explores the design space, feasibility, and effectiveness of a unique VR-based cyberbullying prevention component in a human-centered iterative approach. The central idea is reflected in creating a virtual personal space invasion with virtual objects associated with cyberbullying making the everyday intrusion of victims tangible. A pre-study revealed that harmful speech texts in bright non-removable message boxes best transferred the psychological determinants associated with a personal space invasion to virtual objects contextualized in cyberbullying scenarios. Therefore, these objects were incorporated into a virtual prevention program that was then tested in a laboratory study with 41 participants. The results showed that the intervention could trigger cognitive dissonance and empathy. In the second step, the intervention was evaluated and improved in a focus group with the actual target group of children and adolescents. The improved application was then evaluated in a school workshop for 5 days with 100 children and adolescents. The children understood the metaphor of virtual space invasion by the harmful text boxes and reported the expected psychological effects. They also showed great interest in VR. In summary, this paper contributes to the innovative and effective prevention of cyberbullying by using the potential of VR. It provides empirical evidence from a laboratory experiment and a field study with a large sample from the target group of children and adolescents and discusses implications for future developments.</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":"1 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140147328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tridimensional aligment (registration) is particularly challenging on specific hardware configurations such as Head Mounted Displays (HMDs) that use Optical See-Through (OST) technology. In general, the calibration of HMDs uses deterministic optimization methods. However, non-deterministic methods have been proposed in the literature with promising results in distinct research areas. In this work, we developed a non-deterministic optimization method for the semi-automatic calibration of smartphone-based OST HMDs. We tested simulated annealing, evolutionary strategy, and particle swarm algorithms. We also developed a system for calibration and evaluated it through an application that aligned a virtual object in an AR environment. We evaluated our method using the Mean Squared Error (MSE) at each calibration step, considering the difference between the ideal/observed positions of a set of reference points and those estimated from the values determined for the calibration parameters. Our results show an accurate OST HMD calibration for the peripersonal space, with similar MSEs for the three tested algorithms.\u0000</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":"72 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140147331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was hypothesized that 1) neck vibrations would enhance vection and presence, and 2) CS to negatively relate to presence and vection, whereas presence and vection to positively relate to one another. Thirty-two participants were visually and audibly immersed in a virtual reality flight simulator and occasional neck muscle vibrations were presented. Vection onset and duration were reported through button presses. Turning angle estimations and ratings of vection quality, presence, and CS were obtained after completion of the flights. Results showed no influence of vibrations on turning angle estimation errors, but a medium positive effect of vibrations on vection quality was found.

This illusory model focuses on the dissociation of visual input and somatosensory feedback and tries to induce the sensation of virtual objects' loads in VR users by manipulating visual input. For that, modifications on the control-display ratio, i.e., between the real and virtual motions of the arm, can be used to produce a visual illusionary effect on the virtual objects' positions as well. Therefore, VR users perceive it as velocity variations in the objects' displacements, helping them achieve a better sensation of virtual weight. A primary contribution of this paper is the development of a novel, holistic assessment methodology that measures the sense of the presence in virtual reality contexts, particularly when participants are lifting virtual objects and experiencing their weight. Our study examined the effect of virtual object weight on the kinematic parameters and velocity profiles of participants' upward arm motions, along with a parallel experiment conducted using real weights. By comparing the lifting of real objects with that of virtual objects, it was possible to gain insight into the variations in kinematic features observed in participants' arm motions. Additionally, subjective measurements, utilizing the Borg CR10 questionnaire, were conducted to assess participants' perceptions of hand fatigue. The analysis of collected data, encompassing both subjective and objective measurements, concluded that participants experienced similar sensations of fatigue and changes in hand kinematics during both virtual object tasks, resulting from pseudo-haptic feedback, and real weight lifting tasks. This consistency in findings underscores the efficacy of pseudo-haptic feedback in simulating realistic weight sensations in virtual environments.</p>","PeriodicalId":23727,"journal":{"name":"Virtual Reality","volume":"4 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140073525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
