Examining the notions of scalability and elasticity in interactive visualizations, we introduce a visualization of personal reading traces such as marginalia or markings inside the reference library of German realist author Theodor Fontane. To explore such a rich and extensive collection, meaningful visual forms of abstraction and detail are as important as the transitions between those states. Following a growing research interest in the role of fluid interactivity and animations between views, we are particularly interested in the potential of carefully designed transitions and consistent representations across scales. The resulting prototype addresses humanistic research questions about the interplay of distant and close reading with visualization research on continuous navigation along several granularity levels, using scrolling as one of the main interaction mechanisms. In addition to presenting the design process and resulting prototype, we present findings from a qualitative evaluation of the tool, which suggest that bridging between distant and close views can enhance exploration, but that transitions between views need to be crafted very carefully to facilitate comprehension.}, subject = {Visualisierung}, language = {en} } @article{JungingerOsterdorfAvilaVissirinietal., author = {Junginger, Pauline and Osterdorf, Dennis and Avila Vissirini, Barbara and Voloshina, Anastasia and Hausmann, Timo and Kreiseler, Sarah and D{\"o}rk, Marian}, title = {The close-up cloud : visualizing details of image collections in dynamic overviews}, series = {International Journal for Digital Art History}, volume = {2020}, journal = {International Journal for Digital Art History}, number = {5}, address = {Heidelberg}, organization = {Heidelberg University Library}, issn = {2363-5401}, doi = {10.11588/dah.2020.5.72039}, pages = {6.02 -- 6.13}, abstract = {This paper introduces a visualization technique designed to uncover iconographic patterns prevalent within a collection while at the same time allowing close viewing of these particular details. Challenging an institutionalized understanding of overview and detail as inherently opposed, the intention of this research is to develop a visualization method that accounts for the iconographic abundance of a collection and encourages its casual exploration. Expanding digitization efforts have led to a growing number of rich cultural heritage datasets that are successively being published online. At the same time scholars are exploring the potential of computational methods to expand the scale and scope of art history. In this context, data visualization is often equated with a distanced perspective diminishing the intricate and intriguing details of individual artifacts. In collaboration with a museum of applied and decorative arts, we have devised a novel interface concept for the exploration of image collections such as historical glass plate negatives. Inspired by photographic plates on a light table, the resulting Close-up Cloud translates the art historical method of close viewing into the digital by combining it with a dynamic representation of quantitative iconographic patterns across an entire image collection.}, subject = {Visualisierung}, language = {en} } @article{DoerkMuellerStangeetal., author = {D{\"o}rk, Marian and M{\"u}ller, Boris and Stange, Jan-Erik and Herseni, Johannes and Dittrich, Katja}, title = {Co-Designing Visualizations for Information Seeking and Knowledge Management}, series = {Open Information Science}, volume = {4}, journal = {Open Information Science}, number = {1}, publisher = {De Gruyter Saur}, address = {Berlin}, issn = {2451-1781}, doi = {10.1515/opis-2020-0102}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:525-26188}, pages = {217 -- 235}, abstract = {Creativity is a crucial factor in finding novel and useful visualization and interaction techniques, but its emergence is contingent on the right conditions. The focus of visualization research has traditionally been on techniques, and to a lesser degree on the process of creating them with domain experts and end users. This paper focuses on the collaborative design of visualizations for information seeking and knowledge management. The difficult, yet common challenge in any visualization project is to find meaningful visual representations and useful interaction techniques to carry out complex analysis tasks. The unique difficulty for preparing co-design activities for visualization lies in the gap between the abstract nature of data and the concrete form of visual representations. To bridge this gap, our co-design framework for visualization places particular emphasis on actors, activities, and artifacts as categories that expand the focus of visualization design beyond the traditional triad of users, tasks, and data. Drawing from general co-design principles, the framework is developed and validated during the course of two case studies in the context of information management systems and library collection databases. Based on observed patterns during the case studies, practical tactics provide advice on carrying out co-design in information visualization.}, subject = {Methodologie}, language = {en} } @incollection{BrueggemannBludauDoerk, author = {Br{\"u}ggemann, Viktoria and Bludau, Mark-Jan and D{\"o}rk, Marian}, title = {Zwischen Distanz und N{\"a}he : Formen der Betrachtung und Bewegung in (digitalen) Sammlungen}, series = {Das digitale Objekt : Zwischen Depot und Internet}, booktitle = {Das digitale Objekt : Zwischen Depot und Internet}, publisher = {Deutsches Museum Verlag}, address = {M{\"u}nchen}, isbn = {978-3-948808-00-6}, issn = {2365-9149}, pages = {115 -- 123}, subject = {Digitalisierung}, language = {de} } @article{BrueggemannBludauDoerk, author = {Br{\"u}ggemann, Viktoria and Bludau, Mark-Jan and D{\"o}rk, Marian}, title = {The Fold}, series = {Digital humanities quarterly : DHQ}, volume = {14}, journal = {Digital humanities quarterly : DHQ}, number = {3}, address = {USA}, organization = {Association for Computers and the Humanities}, issn = {1938-4122}, pages = {1 -- 16}, abstract = {We propose the philosophical notion of the fold as an evocative vocabulary for the design and critique of interactive data visualizations. An expanding range of application areas, such as digital art history and literary studies, illustrates the potential of data visualization for research and education in the humanities. Coinciding with the increasing currency of data as evidence in the humanities, this research addresses a growing interest in data visualization for visual analysis and argumentation. For example, cultural collection visualizations promise a range of possibilities for visual and interactive representations of digital cultural heritage, used both for free exploration and focused research. Based on the concept of the fold, prominently advanced by Gilles Deleuze, this paper outlines a critical framework that draws attention towards the complexity of the underlying data. The fold offers a way to analyze and conceptualize visualizations through the lens of three integrated operations: explication, implication, and complication. It is an opportunity to think of interactive visualizations as portals into coherent, elastic, and ultimately infinite information spaces. Accordingly, it rejects the separation between interactivity and visual encoding and draws attention to the transitions between multiple states of a visualization. We identify design patterns of the fold in data visualizations, devise a framework for the critical interpretation of interactivity in data visualization, and demonstrate the implications for the digital humanities.}, subject = {Visualisierung}, language = {en} } @inproceedings{MenzelBludauLeitneretal., author = {Menzel, Sina and Bludau, Mark-Jan and Leitner, Elena and D{\"o}rk, Marian and Moreno-Schneider, Juli{\´a}n and Petras, Vivien and Rehm, Georg}, title = {Graph Technologies for the Analysis of Historical Social Networks Using Heterogeneous Data Sources}, series = {Graph Technologies in the Humanities}, booktitle = {Graph Technologies in the Humanities}, editor = {Andrews, Tara and Diehr, Franziska and Efer, Thomas and Kuczera, Andreas and van Zundert, Joris}, address = {Wien}, organization = {Universit{\"a}t Wien}, issn = {1613-0073}, pages = {124 -- 149}, abstract = {Over the last decades, cultural heritage institutions have provided extensive machine-readable data, such as bibliographic and archival metadata, full-text collections, and authority records containing multitudes of implicit and explicit statements about the social relations between various types of entities.

Emosaic is grounded in psychological research on the relationship between language, affect, and color perception. We capitalize on an established three-dimensional model of human emotion: valence (good, nice vs. bad, awful), arousal (calm, passive vs. exciting, active) and dominance (weak, controlled vs. strong, in control). Previously, multi-dimensional models of emotion have been used rarely in visualizations of textual data, due to the perceptual challenges involved. Furthermore, until recently most text visualizations remained at a high level, precluding closer engagement with the deep semantic content of the text. Informed by empirical studies, we introduce a color mapping that translates any point in three-dimensional affective space into a unique color. Emosaic uses affective dictionaries of words annotated with the three emotional parameters of the valence-arousal-dominance model to extract emotional meanings from texts and then assigns to them corresponding color parameters of the hue-saturation-brightness color space. This approach of mapping emotion to color is aimed at helping readers to more easily grasp the emotional tone of the text. Several features of Emosaic allow readers to interactively explore the affective content of the text in more detail; e.g., in aggregated form as histograms, in sequential form following the order of text, and in detail embedded into the text display itself. Interaction techniques have been included to allow for filtering and navigating of text and visualizations.}, subject = {Mensch-Maschine-Kommunikation}, language = {en} }
