Co-Designing Visualizations for Information Seeking and Knowledge Management

— Open Information Science‚ 4(1), pages 217-235, 2020
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.

Die bibliografischen Daten der Deutschen Nationalbibliothek entfalten

— Dialog mit Bibliotheken, 2018

Wie sieht die Zukunft der Recherche in digitalen Bibliothekskatalogen aus? Wie können umfangreiche und heterogene Sammlungsbestände mit Hilfe von Datenvisualisierungen besser zugänglich gemacht werden? Kann man durch eine digitale Bibliothek flanieren und dabei den Bestand auf ganz neue Art entdecken? Diese Fragen standen im Zentrum eines Forschungsprojekts, das ein interdisziplinäres Team von Forscherinnen und Forschern des Urban Complexity Lab der FHP im vergangenen Jahr in Kooperation mit der DNB durchgeführt hat. Dieser Artikel stellt das Hauptergebnis des Projekts vor: DNBVIS, der Prototyp eines experimentellen Kataloginterfaces. Anschließend werden die Vorgehensweise und wichtigsten Erkenntnisse des Projekts zusammengefasst.
