Therefore, it is necessary to find solutions to this limitation. A possible solution could be to reuse this workspace by overlapping different parts of the virtual space. This can be achieved through the use of imperceptible portals that connect different points in the virtual environment. Thanks to these portals it is possible to create a momentary break in the conventional Euclidean geometry displaying parts of the virtual world that are farther away than usual. Although this kind of effect has been seen in conventional games, its application to virtual environments has some technical implications. One of the most important technical characteristics to be evaluated is the presence, which could be affected by this type of visual effect. For this reason, a validation of the effect has been carried out by quantitatively analyzing the perceptual presence and conducting qualitative interviews with users. The results did not show an overall impact on presence, and users were excited to experience this type of visual effect inside the virtual world. Finally, this article shows everything learned in this development and is discussed from a perceptual design point of view, opening the possibility of new studies associated with this visual effect applied to the virtual world.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"98 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140371163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it becomes important to understand the performance of human hand-reaching movement in MR. Studies have shown that different virtual environment visualization modalities can affect point-to-point reaching performance using a stylus, but it is not yet known if these effects translate to direct human-hand interactions in mixed reality. This paper focuses on evaluating human point-to-point motor performance in MR and VR for both finger-pointing and cup-placement tasks. Six performance measures relevant to haptic interface design were measured for both tasks under several different visualization conditions (“MR with indicator”, “MR without indicator”, and “VR”) to determine what factors contribute to hand-reaching performance. A key finding was evidence of a trade-off between reaching motion confidence” measures (indicated by throughput, number of corrective movements, and peak velocity) and “accuracy” measures (indicated by end-point error and initial movement error). Specifically, we observed that participants tended to be more confident in the “MR without Indicator” condition for finger-pointing tasks. These results contribute critical knowledge to inform the design of VR/MR interfaces based on the application's user performance requirements.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"125 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140369931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing upon the Proteus effect, avatars can positively and negatively affect health behaviors, depending on whether the avatar appearance is aligned with stereotypes about healthy or unhealthy behavior. Investigating avatar appearances is essential to understand potential negative health effects. Three experiments in a non-immersive virtual supermarket examined whether controlling an overweight avatar negatively affected 1) intentions to eat healthy and 2) food choice healthiness in the virtual supermarket, thereby investigating avatar allocation type (Study 1) and visual perspective (Study 2) as moderators. 2 (Avatar body size: overweight vs. healthy weight) by 2 (Avatar allocation type: self-assigned vs. experimenter-assigned [Study 1]; Visual perspective: first-person vs. third-person [Studies 2 and 3]) between-subjects designs were employed. None of the studies demonstrated the Proteus effect and no moderating role of avatar allocation type was found (Study 1). Unexpectedly, controlling an overweight avatar resulted in stronger intentions to eat healthy from a third-person perspective only (Study 2), which led to the hypothesis that the overweight avatar functioned as a fear stimulus. To test this, a health message was added that highlighted obesity as a health risk (Study 3). The addition of this message did not affect intentions to eat healthy and food choice healthiness. The combination of fear appeal and self-perception theory as explanatory frameworks for behavioral responses to avatars opens avenues for new research, such as exploring specific conditions that trigger each effect.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140248605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This trend is accompanied with an increase in studies aimed at scientifically examining the characteristics and principles of immersive visual storytelling. This paper intends to contribute to this growing field by offering a comprehensive review on the current research development in Cinematic Virtual Reality (CVR), which employs VR technology to produce immersive, cinematic experiences for audiences. While extant research has focused on the content generation techniques and human performance implicated in virtual environments, such investigations may not fully explain the medium adaptation differences or emotional dimensions of narrated immersive experiences. These aspects are especially crucial in the context of visual storytelling through VR film, 360-degree video production, or other narrated experiences. The proposed study systematically categorizes CVR-related research, revealing the field's current state by narrowing the focus to specific topics and themes within CVR literature, and highlighting key sub-domains of interest centered on viewers' experience measurement techniques. The findings of this review are expected to establish formal categories for implementing visual CVR to achieve immersive visual storytelling and provide a comprehensive analysis of current viewer experience measurements.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"117 39","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140079134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have shown that demographic and basic personality traits are associated with game behaviors in massively multiplayer online role-playing games. However, little is known about the roles of trait aggression and game motivations, especially in multiplayer online battle arena games. Thus, the aim of this study was to investigate how demographic, trait aggression, and game motivations affect multiplayer online battle arena game behaviors. A total of 1,316 Chinese adolescent gamers who play Honor of Kings responded to questions related to demographic information, trait aggression, game motivations (socializer, competitor, escapist, story-driven, completionist, and smarty-pants), and game behaviors (aggressing, winning, creating, and helping). The multiple linear regression model results showed that males, socializers, completionists, and smarty-pants were more likely to exhibit aggressing, winning, creating, and helping behaviors. Trait aggression predicted aggressing, winning, and creating behaviors. Moreover, age and competitor scale positively predicted aggressing and winning behaviors. Meanwhile, escapists tended to engage in aggressing and creating behaviors, and story-driven players exhibited creating and helping behaviors. These results may be useful in explaining individual differences in game behaviors and the relationships between video game and real-life behaviors for gamers.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"235 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140448614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the purpose of implementing more dexterous and complex tasks, we proposed a novel framework with dual-hand master teleoperation systems under time varied delays. In this paper, we emphasized studying the bilateral grasping teleoperation control as the time delay caused a communication outage. Combing a wave-variable structure with a four-channel framework, an event-trigger-based bilateral sliding mode teleoperation control and an adaptive neural network are designed to effectively achieve master-slave trajectory tracking. In the virtual 3D environment, we created an mixed reality interface based on dual-hand master teleoperation control that effectively responded to the two Omni manipulators' position transformation of the virtual manipulator. The time delay between the real slave force feedback and the virtual interface is addressed by designed event-trigger-based control so as to efficiently reduce the impact of time communication outage. The system's stability is analyzed and robot experiments are performed. From the experimental results, the telepresence platform innovatively applied virtual force feedback to reveal the soft target grasping and to accurately estimate the interactive force, enabling sensorless force feedback control.","PeriodicalId":501553,"journal":{"name":"PRESENCE: Virtual and Augmented Reality","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139386342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
