In contrast, the dynamic nature of virtual reality (VR) environments establishes virtual museums as a more potent space for both layout optimization and narrative construction, particularly when integrating visitors’ diverse preferences to optimize the virtual museum and convey narratives. Therefore, we first collaborated with experienced curators to conduct a formative study to understand the workflow of curation and summarize the museum narratives that weave exhibits, galleries, and museum architecture into a compelling story. We then proposed a museum spatial layout framework that clarified three narrative levels (exhibit level, gallery level, and architecture level) to support the controllable spatial layout of the museum’s elements. Based on that, we developed VirtuNarrator, a proof-of-concept prototype designed to assist visitors in choosing different narrative themes, filtering exhibits, creating and adjusting galleries, and freely connecting them. The evaluation results validated that visitors received a more systematic museum narrative experience and perceptions of multi-perspective narrative design in VirtuNarrator. We also provided insights into VR-based museum narrative enhancement beyond spatial layout design.</div></div>","PeriodicalId":36903,"journal":{"name":"Visual Informatics","volume":"9 3","pages":"Article 100257"},"PeriodicalIF":3.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145096888","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}

We propose a realistic, cartoon-like representation of the players and discuss its integration into a typical positional diagram. To overcome the cost of generating player representations depicting their pose, we propose a method to generate such representations from minimal user input. We conducted a user study to evaluate the effectiveness of our pose-aware diagrams. The tasks for the study were designed to encompass the main in-game scenarios in padel, which include the ballholder at the net with opponents defending, the reverse situation, and transitions between these two states.

The major drawback of SLTA-based visualizations is numerical diffusion caused by iterative texture interpolation. We focus on reducing numerical diffusion in techniques that use textures sparsely populated by solid blobs, such as typically in dye advection. A ReLU-based model architecture is the foundation of our ML-based approach. Multiple model configurations are trained to learn a performant interpolation model that reduces numerical diffusion. Our evaluation investigates the models’ ability to generalize concerning the flow and length of the advection process. The model with the best tradeoff between the computational effort to compute, quality of the result, and generality of application is found to be single-layer ReLU-based. This model is further analyzed and explained in-depth and improved using symmetry constraints. Additionally, a metamodel is fitted to predict single-layer ReLU model parameters for advection processes of any length. The metamodel removes the need for any prior training when applying our technique to a new scenario. Additionally, we show that our model is compatible with Back and Forth Error Compensation and Correction to improve the quality of the advection result further. We demonstrate that our model shows excellent diffusion reduction properties in typical examples of 3D steady and unsteady flow visualization. Finally, we utilize the strong diffusion reduction capabilities of our model to compute dye advection with exponential decay, a novel method that we introduce to visualize the extent and evolution of unsteadiness in both 2D and 3D unsteady flow.</div></div>","PeriodicalId":36903,"journal":{"name":"Visual Informatics","volume":"9 3","pages":"Article 100242"},"PeriodicalIF":3.8,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144933920","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}

However, existing works primarily rely on user-intensive manipulation of the camera, with little effort put into automating the process. To fill the gap, this paper proposes <em>CineFolio</em>, a semi-automated camera planning method to reduce manual effort and enhance user experience in immersive narrative visualization. <em>CineFolio</em> combines cinematic theories with graphics criteria, considering both information delivery and aesthetic enjoyment to ensure a comfortable and engaging experience. Specifically, we parametrize the considerations into optimizable camera properties and solve it as a constraint satisfaction problem (CSP) to realize common camera types for narrative visualization, namely <em>overview camera</em> for absorbing the scale, <em>focus camera</em> for detailed views, <em>moving camera</em> for animated transitions, and <em>user-controlled camera</em> allowing users to provide inputs to camera planning. We demonstrate the feasibility of our approach with cases of various data and chart types.
