We conducted a 2x2 mixed design experiment involving 60 participants who interacted with either synchronously moving virtual humans or independently moving ones, each with self-similar or generic appearances, across two consecutive AR sessions. Participants evaluated their sense of embodiment, self-identification, and body weight perception of the virtual human. Our results show that self-similarity significantly enhanced sense of embodiment, self-identification, and the accuracy of body weight estimates with the virtual human. However, the effects of having motor control over the virtual human movements were notably weaker in these measures than in similar VR studies. Further analysis indicated that not only the virtual human itself but also the participants' body weight, self-esteem, and body shape concerns predict body weight estimates across all conditions. Our work advances the understanding of virtual human body weight perception in AR systems, emphasizing the importance of factors such as coherence with the real-world environment.","PeriodicalId":94035,"journal":{"name":"IEEE transactions on visualization and computer graphics","volume":"PP ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143652910","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 study explores redirection approaches in virtual reality (VR) to correct golfers' swing paths through strategic ball shifting. By initiating a forward ball shift just before impact, we aim to prompt golfers to react and modify their swing motion, thereby eliminating undesirable swing habits. Building on recent research, our VR-based methods incorporate a gradual transformation of visuomotor associations to enhance motor skill learning. In this study, we develop three ball shift patterns, including a novel pattern that employs gradual ball shifts with interspersed normal conditions, designed to retain learning effects post-training. A preliminary study, including expert interviews, assesses the feasibility of various ball-shifting directions. Subsequently, a comprehensive user study measures the learning effects across different ball shift modes. The results indicate that our proposed redirection mode effectively corrects swing paths and yields a sustained learning effect.","PeriodicalId":94035,"journal":{"name":"IEEE transactions on visualization and computer graphics","volume":"PP ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143652917","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}

Recent advances use an end-to-end neural network to learn the project-and-capture process. However, these neural network-based methods often implicitly encapsulate scene parameters, such as surface material, gamma, and white balance in the network parameters, and are less interpretable and hard for novel scene simulation. Moreover, neural networks usually learn the indirect illumination implicitly in an image-to-image translation way which leads to poor performance in simulating complex projection effects such as soft-shadow and interreflection. In this paper, we introduce a novel path tracing-based differentiable projector-camera systems (DPCS), offering a differentiable ProCams simulation method that explicitly integrates multi-bounce path tracing. Our DPCS models the physical project-and-capture process using differentiable physically-based rendering (PBR), enabling the scene parameters to be explicitly decoupled and learned using much fewer samples. Moreover, our physically-based method not only enables high-quality downstream ProCams tasks, such as ProCams relighting and projector compensation, but also allows novel scene simulation using the learned scene parameters. In experiments, DPCS demonstrates clear advantages over previous approaches in ProCams simulation, offering better interpretability, more efficient handling of complex interreflection and shadow, and requiring fewer training samples.

However, most of the previous techniques only consider the first-order dependencies among blocks, which is insufficient in describing complex flow patterns. In this work, we present FlowHON, an approach to construct higher-order networks (HONs) from flow fields. FlowHON captures the inherent higher-order dependencies in flow fields as nodes and estimates the transitions among them as edges. We formulate the HON construction as an optimization problem with three linear transformations. The first two layers correspond to the node generation and the third one corresponds to edge estimation. Our formulation allows the node generation and edge estimation to be solved in a unified framework. With FlowHON, the rich set of traditional graph algorithms can be applied without any modification to analyze flow fields, while leveraging the higher-order information to understand the inherent structure and manage flow data for efficiency. We demonstrate the effectiveness of FlowHON using a series of downstream tasks, including estimating the density of particles during tracing, partitioning flow fields for data management, and understanding flow fields using the node-link diagram representation of networks.","PeriodicalId":94035,"journal":{"name":"IEEE transactions on visualization and computer graphics","volume":"PP ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631140","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}

However, when visual information is presented, sound localization results from multimodal integration. Additionally, using headmounted displays leads to a distortion of visual egocentric distances. With two different paradigms, we investigated the extent to which different visual scenes influence auditory distance perception, and secondary presence and realism. To be more precise, different room models were displayed via HMD while participants had to localize sounds emanating from real loudspeakers. In the first paradigm, we manipulated whether a room was congruent or incongruent to the physical room. In a second paradigm, we manipulated room visibility - displaying either an audiovisual congruent room or a scene containing almost no spatial information- and localization task. Participants indicated distances either by placing a virtual loudspeaker, walking, or verbal report. While audiovisual room incongruence had a detrimental effect on distance perception, no main effect of room visibility was found but an interaction with the task. Overestimation of distances was higher using the placement task in the non-spatial scene. The results suggest an effect of visual scene on auditory perception in VR implying a need for consideration e.g., in virtual acoustics research.","PeriodicalId":94035,"journal":{"name":"IEEE transactions on visualization and computer graphics","volume":"PP ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631142","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 asymmetric tasks, users might need to access different resources (information, objects, tools) distributed throughout their room. Existing intersection methods do not support such interactions, because a large portion of the telepresence participants' rooms become inaccessible, along with the relevant task resources. We propose MRUnion, a Mixed Reality Telepresence pipeline for asymmetric task-aware 3D mutual scene generation. The key concept of our approach is to enable a user in an asymmetric telecollaboration scenario to access the entire room, while still being able to communicate with remote users in a shared space. For this purpose, we introduce a novel mutual room layout called Union. We evaluated 882 space combinations quantitatively involving two, three, and four combined remote spaces and compared it to a conventional Intersect room layout. The results show that our method outperforms existing intersection methods and enables a significant increase in space and accessibility to resources within the shared space. In an exploratory user study (N=24), we investigated the applicability of the synthetic mutual scene in both MR and VR setups, where users collaborated on an asymmetric remote assembly task. The study results showed that our method achieved comparable results to the intersect method but requires further investigation in terms of social presence, safety and support of collaboration. From this study, we derived design implications for synthetic mutual spaces.","PeriodicalId":94035,"journal":{"name":"IEEE transactions on visualization and computer graphics","volume":"PP ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631143","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}

Augmented reality (AR) is a promising tool to address this limitation by providing sensory substitution through visual or vibrotactile feedback. The implementation of visual force feedback requires consideration not only of feedback design but also of positioning. Therefore, we implemented two different visualization types at three different positions and investigated the effects of vibrotactile feedback on these approaches. Furthermore, we examined the effects of multimodal feedback compared to visual or vibrotactile output alone. Our results indicate that sensory substitution eases the interaction in contrast to a feedback-less baseline condition, with the presence of visual support reducing average force errors and being subjectively preferred by the participants. However, the more feedback was provided, the longer users needed to complete their tasks. Regarding visualization design, a 2D bar visualization reduced force errors compared to a 3D arrow concept. Additionally, the visualizations being displayed directly on the ultrasound screen were subjectively preferred. With findings regarding feedback modality and visualization design our work represents an important step toward sensory substitution for touchless human-robot interaction.","PeriodicalId":94035,"journal":{"name":"IEEE transactions on visualization and computer graphics","volume":"PP ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631133","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}

Body language, facial expressions, personal spaces, and social touch are multiple factors influencing how a stranger's approach is experienced. Furthermore, the rise of virtual social platforms raises concerns about virtual harassment and the perception of personal space in VR: harassment is felt much more strongly in virtual spaces, and the psychological effects can be just as severe. While most virtual platforms have a 'personal bubble' feature that keeps strangers at a distance, it does not seem to suffice: personal space violations seem influenced by more than simply distance. With this paper, we aim to further clarify the variability of personal spaces. We focus on haptic stimulation, elaborating our hypotheses on the relationship between social touch and the perception of personal spaces. Users wore a haptic compression belt and were immersed in a virtual dark alley. Virtual agents approached them while exhibiting either neutral or threatening body language. In half of all trials, as the agent advanced, the compression belt tightened around the users' torsos with three different pressures. Participants could press a response button when uncomfortable with the agent's proximity. Peripersonal space violations occurred 31% earlier on average when the agent was visibly angry and the compression belt activated. A greater tightening pressure also slightly increased the personal sphere radius by up to 13%. Overall, our results are consistent with previous works on peripersonal spaces. They help further define our relationship to personal space boundaries and encourage using haptic devices during simulated social interactions in VR.","PeriodicalId":94035,"journal":{"name":"IEEE transactions on visualization and computer graphics","volume":"PP ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627269","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}
