Der Workshop hinterfragt partizipativ die Visualisierungskultur und Wahrnehmungs- bzw. Nutzungspraktiken digitaler Kulturerbe-Daten am Beispiel musealer Sammlungen im Web. Im Zentrum steht dabei der Einsatz von Eyetracking-Verfahren sowie Methoden der heuristischen Usability-Evaluation. Ausgehend von den Webseiten "explorativ" gestalteter Online Sammlungen werden die graphischen Benutzeroberflächen als visuelle Schnittstelle zwischen interner Objektdatenbank und Rezipientenschaft kritisch beleuchtet. In engem Austausch mit den Teilnehmer*innen sollen die User Experience praktisch erforscht werden. Dazu gehören einerseits Fragen nach den Wahrnehmungsstrukturen und der intuitiven Nutzung der Seiten, ihrer Zeichen und Navigation. Andererseits wird explizit ein Augenmerk auf die angebotene Auswahl der Informationen von v.a. Einzelobjektseiten und das Vernetzungspotential verlinkter Daten als Möglichkeit der Kunstvermittlung gelegt.
Drag-and-drop cognition
(2015)
We present a newly developed graphical user interface, which allows researchers to create models of complex societal decision-making in a user-friendly manner without being required to program. The software tool is based on InnoMind, an agent-based model that implements theories of emotional cognition from cognitive science. We show the current work in progress and outline the near-term goals of the software development project.
Visual Filter
(2014)
Network log files often need to be investigated manually for suspicious activity. The huge amount of log lines complicates maintaining an overview, navigation and quick pattern identification. We propose a system that uses an interactive visualization, a visual filter, representing the whole log in an overview, allowing to navigate and make context-preserving subselections with the visualization and in this way reducing the time and effort for security experts needed to identify patterns in the log file. This explorative interactive visualization is combined with focused querying to search for known suspicious terms that are then highlighted in the visualization and the log file itself.
We created a pixel map for multivariate data based on an analysis of the needs of network security engineers. Parameters of a log record are shown as pixels and these pixels are stacked to represent a record. This allows a broad view of a data set on one screen while staying very close to the raw data and to expose common and rare patterns of user behavior through the visualization itself (the "Carpet"). Visualizations that immediately point to areas of suspicious activity without requiring extensive filtering, help network engineers investigating unknown computer security incidents. Most of them, however, have limited knowledge of advanced visualization techniques, while many designers and data scientists are unfamiliar with computer security topics. To bridge this gap, we developed visualizations together with engineers, following a co-creative process. We will show how we explored the scope of the engineers' tasks and how we jointly developed ideas and designs. Our expert evaluation indicates that this visualization helps to scan large parts of log files quickly and to define areas of interest for closer inspection.
Monadic Exploration
(2014)
Monadic exploration is a new approach to interacting with relational information spaces that challenges the distinction between the whole and its parts. Building on the work of sociologists Gabriel Tarde and Bruno Latour we turn to the concept of the monad as a useful lens on online communities and collections that expands the possibility for creating meaning in their navigation. While existing interfaces tend to emphasize either the structure of the whole or details of a part, monadic exploration brings these opposing perspectives closer together in continuous movements between partially overlapping points of view. We present a visualization that reflects a given node's relative position within a network using radial displacements and visual folding. To investigate the potential of monadic exploration we report on an iterative design process of a web-based visualization of a highly cross-referenced book and its six-month deployment.
We present a visualization of subject headings that typically accompany books as flat textual metadata. The purpose of the visualization is twofold: first to expose the implicit structure in subject headings as an overview of a library collection and second to present a visual web of keywords to invite exploration of books. Taking a tag cloud as a starting point, the visualization extends it to a networked tag cloud that respects the hierarchy that is implicit in subject headings. By allowing an information seeker to successively build a subject filter, while seeing the results at each step, we hope to improve the searcher’s orientation in a comprehensive book collection.
A photo archive contains diverse narratives that only get partially exposed in digital interfaces. In this paper we explore a potential framework for archivists and designers to create photo archive interfaces that are sensitive to the ethos and social context of its content. We outline our approach to engaging with archival projects and present the results of a pilot workshop, which raised a range of complex questions about the design of visual interfaces. Our aim is to practically and conceptually expand how a visual interface would let a visitor access, explore, and interpret the contents of an archive. To do this we are interested in the different associations that people weave between the artefacts of an archive.
Culturegraphy visualizes cultural information exchange over time. Treating cultural works as nodes and influences as directed edges, the visualization of these cultural networks can provide new insights into the rich interconnections of cultural development. The graphics represent complex relationships of movie references by combining macro views summarizing 100 years of movie influences with micro views providing a close-up look at the embedding of individual movies. The macro view shows the rise of the self-referential character of postmodern cinema, while the micro level illustrates differences between individual movies, when they were referenced and by whom. The visualizations provide views that are closer to the real complexity of the relationships than aggregated views or rankings could do.
WordWanderer
(2015)
Text visualisations provide visual representations of documents or small corpora with the primary aim of supporting language analysis. We are interested in developing a more playful approach to language that can be characterised by the notion of wandering as an open-ended movement. To support such a casual form of engagement with text, we designed the WordWanderer system: a visualisation technique that extends tag clouds into a navigational interface for text. The tool supports the gradual movement between word ‘context views’, which represent the words that co-occur in the vicinity of the selected word, and word-‘comparison views’, which arrange words based on their association strengths between two selected words. We report on the encouraging feedback from a ten-day deployment of the interface and present promising directions for future design and research.
