Item Integrating Sonification and Visualization - But Why?(The Eurographics Association, 2024) Rind, Alexander; Enge, Kajetan; Iber, Michael; Rönnberg, Niklas; Lenzi, Sara; Elmquist, Elias; Caiola, Valentina; Lan, Fangfei; Höldrich, Robert; Aigner, Wolfgang; Schulz, Hans-Jörg; Isenberg, TobiasThe research communities studying visualization and sonification share exceptionally similar goals, essentially aiming to make data interpretable to humans. One community uses visual representations, while the other employs auditory (nonspeech) representations of data. Although the two communities have much in common, they developed mostly in parallel, with only comparatively few examples of integrated audiovisual data analysis idioms presented so far. This panel brings together researchers from both the fields of visualization and sonification to collectively discuss the question: 'Integrating Sonification and Visualization - but why?' In the panel discussion, we will tackle this question along two main hypotheses: Combining the modalities to (1) increase the ''bandwidth from data to brain,'' or (2) to increase a user's personal engagement during the data analysis process. On the one hand, designers might aim to communicate more data in less time or gain more and more complex insights from the data by using a multi-modal display. This argument follows an understanding that two senses should be capable of processing more information than ''just'' one. On the other hand, sometimes, a more engaged analysis of the represented data is desirable. Engagement with data visualization stands as a crucial topic in numerous contexts within our field, encouraging ''deeper'' thinking by expert analysts, readers of data journalism articles, and students in educational settings. We hypothesize that integrating visualization with sonification holds the potential to enhance user engagement during analysis. Through the panel discussion, we want to delve into the spectrum between aiming for bandwidth and engagement, seeking to understand the opportunities and challenges of integrating sonification and visualization.Item Open Your Ears and Take a Look: A State-of-the-Art Report on the Integration of Sonification and Visualization(The Eurographics Association and John Wiley & Sons Ltd., 2024) Enge, Kajetan; Elmquist, Elias; Caiola, Valentina; Rönnberg, Niklas; Rind, Alexander; Iber, Michael; Lenzi, Sara; Lan, Fangfei; Höldrich, Robert; Aigner, Wolfgang; Garth, Christoph; Kerren, Andreas; Raidou, RenataThe research communities studying visualization and sonification for data display and analysis share exceptionally similar goals, essentially making data of any kind interpretable to humans. One community does so by using visual representations of data, and the other community employs auditory (non-speech) representations of data. While the two communities have a lot in common, they developed mostly in parallel over the course of the last few decades. With this STAR, we discuss a collection of work that bridges the borders of the two communities, hence a collection of work that aims to integrate the two techniques into one form of audiovisual display, which we argue to be ''more than the sum of the two.'' We introduce and motivate a classification system applicable to such audiovisual displays and categorize a corpus of 57 academic publications that appeared between 2011 and 2023 in categories such as reading level, dataset type, or evaluation system, to mention a few. The corpus also enables a meta-analysis of the field, including regularly occurring design patterns such as type of visualization and sonification techniques, or the use of visual and auditory channels, showing an overall diverse field with different designs. An analysis of a co-author network of the field shows individual teams without many interconnections. The body of work covered in this STAR also relates to three adjacent topics: audiovisual monitoring, accessibility, and audiovisual data art. These three topics are discussed individually in addition to the systematically conducted part of this research. The findings of this report may be used by researchers from both fields to understand the potentials and challenges of such integrated designs while hopefully inspiring them to collaborate with experts from the respective other field.Item Mapping the Landscape of Data Visualizations in Schools and Educational Resources(The Eurographics Association, 2024) Boucher, Magdalena; Stoiber, Christina; Kejstova, Magdalena; Kandlhofer, Martin; Ertl, Alena; Kriglstein, Simone; Aigner, Wolfgang; Firat, Elif E.; Laramee, Robert S.; Andersen, Nicklas SindelvThis study explores the use of data visualizations in school education, examining how they are integrated into teaching practices and materials. By conducting semi-structured interviews with 15 teachers across Austria and Slovakia, coupled with a thorough classification of 5,655 data visualizations in 54 Austrian school textbooks, we gained insights into the landscape of visualization types used in educational settings. Despite the discovery of a wide array of visualization types, our analysis reveals a predominant reliance on simple business charts, highlighting a gap in the variety of methods and resources available for effectively teaching a wider range of visualizations. From our research, we derive lessons learned that pave the way for future development of educational methods and materials to enhance visualization literacy in schools.Item EuroVis 2024 CGF 43-3: Frontmatter(The Eurographics Association and John Wiley & Sons Ltd., 2024) Aigner, Wolfgang; Archambault, Daniel; Bujack, Roxana; Aigner, Wolfgang; Archambault, Daniel; Bujack, RoxanaItem The Past Is All Around You: Augmenting Cultural Heritage On-Site(The Eurographics Association, 2025) Passecker, Markus; Miksch, Silvia; Proksa, Franziska; Aigner, Wolfgang; Diehl, Alexandra; Kucher, Kostiantyn; Médoc, NicolasDigitized cultural heritage (CH) artifacts frequently lose their original immersive and historical context when presented through traditional digital means. Situated visualization, particularly through augmented reality (AR), offers a promising avenue to reconnect artifacts with their authentic physical environments. In this work, our objective is to explore methods for designing effective AR-based visualizations to enhance user engagement and understanding in cultural heritage contexts. We share initial insights derived from literature reviews, prototyping, and preliminary evaluations focusing on prominent Austrian CH sites.Item Instructional Comics for Self-Paced Learning of Data Visualization Tools and Concepts(The Eurographics Association and John Wiley & Sons Ltd., 2025) Boucher, Magdalena; AlKadi, Mashael; Bach, Benjamin; Aigner, Wolfgang; Aigner, Wolfgang; Andrienko, Natalia; Wang, BeiIn this paper, we introduce instructional comics to explain concepts and routines in data visualization tools. As tools for visual data exploration proliferate, there is a growing need for tailored training and onboarding demonstrating interfaces, concepts, and interactions. Building on recent research in visualization education, we detail our iterative process of designing instructional comics for four different types of instructional content. Through a mixed-method eye-tracking study involving 20 participants, we analyze how people engage with these comics when using a new visualization tool, and validate our design choices. We interpret observed behaviors as unique affordances of instructional comics, supporting their use during tasks and complementing traditional instructional methods like video tutorials and workshops, and formulate six guidelines to inform the design of future instructional comics for visualization.Item NODKANT: Exploring Constructive Network Physicalization(The Eurographics Association and John Wiley & Sons Ltd., 2025) Pahr, Daniel; Bartolomeo, Sara Di; Ehlers, Henry; Filipov, Velitchko Andreev; Stoiber, Christina; Aigner, Wolfgang; Wu, Hsiang-Yun; Raidou, Renata Georgia; Aigner, Wolfgang; Andrienko, Natalia; Wang, BeiPhysicalizations, which combine perceptual and sensorimotor interactions, offer an immersive way to comprehend complex data visualizations by stimulating active construction and manipulation. This study investigates the impact of personal construction on the comprehension of physicalized networks. We propose a physicalization toolkit-NODKANT-for constructing modular node-link diagrams consisting of a magnetic surface, 3D printable and stackable node labels, and edges of adjustable length. In a mixed-methods between-subject lab study with 27 participants, three groups of people used NODKANT to complete a series of low-level analysis tasks in the context of an animal contact network. The first group was tasked with freely constructing their network using a sorted edge list, the second group received step-by-step instructions to create a predefined layout, and the third group received a pre-constructed representation. While free construction proved on average more time-consuming, we show that users extract more insights from the data during construction and interact with their representation more frequently, compared to those presented with step-by-step instructions. Interestingly, the increased time demand cannot be measured in users' subjective task load. Finally, our findings indicate that participants who constructed their own representations were able to recall more detailed insights after a period of 10-14 days compared to those who were given a pre-constructed network physicalization. All materials, data, code for generating instructions, and 3D printable meshes are available on https://osf.io/tk3g5/.Item EuroVis 2025 CGF 44-3: Frontmatter(The Eurographics Association and John Wiley & Sons Ltd., 2025) Aigner, Wolfgang; Andrienko, Natalia; Wang, Bei; Aigner, Wolfgang; Andrienko, Natalia; Wang, Bei
