We focus on collaborative processes in augmented reality (AR) that play an essential role in on-site and remote teaching alike. From a teaching perspective, it is important in such scenarios to communicate content and tasks effectively, observe whether students understand the task, and help appropriately. In our setting, students work with head-mounted displays with eye-tracking support to collaborate in a co-located space. The supervisor can observe the scene and the students and interact with them in a hybrid setup using both AR and a desktop PC. Attention monitoring and guidance are facilitated via a bidirectional mapping between 2D structural formulas and 3D molecules. We showcase our approach with an interactive teaching scenario in which chemistry students learn aspects of stereochemistry by interacting with virtual 3D models of molecular structures.

In situated data visualization, the data are directly visualized near their data referent (i.e., the physical space, object, or person it refers to) (Bressa et al., 2022). Situated visualizations are often useful in contexts where the data referent or the viewer does not remain stationary but is in relative motion. For example, a runner looks at visualizations from their fitness band while running. Reading visualizations in such scenarios might be impacted by motion factors. As such, understanding how to best design visualizations with motion factors is important. We define visualizations in motion as visual data representations used in contexts that exhibit relative motion between a viewer and an entire visualization. We propose a research agenda to understand what research opportunities and challenges are under visualization in motion (Yao et al., 2022). Next, we investigate (a) how motion factors can affect the reading accuracy of visualizations (Yao et al., 2022), (b) how to design and embed visualizations in motion in a real application scenario (Yao et al., 2024), and (c) the user experience and design tradeoffs of visualization in motion through a case study (Yao et al., 2024).</p>","PeriodicalId":55026,"journal":{"name":"IEEE Computer Graphics and Applications","volume":"44 6","pages":"142-150"},"PeriodicalIF":1.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143544541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we present BRPVis, an interactive visual analytics system designed to assist bus route planners in exploring optimal solutions through multilevel visualization and rich interaction design.
