Our tangible user interface consists of a large display showing projects on a map, and a polyhedral object to browse these data interactively by selecting and filtering various metadata facets. In this paper we describe a prototype employing new methods to communicate territorial data in visual and tangible ways. The object reduces the barrier between the physical world and virtual data, and eases the understanding of faceted geographical data, enabling urban planners and citizens alike to participate in the discovery and analysis of information referring to the physical world.}, subject = {Gegenst{\"a}ndliche Benutzeroberfl{\"a}che}, language = {en} } @inproceedings{Eichhorn, author = {Eichhorn, Elisabeth}, title = {Recording inner life}, series = {TEI '10 : Proceedings of the fourth international conference on Tangible, embedded, and embodied interaction}, booktitle = {TEI '10 : Proceedings of the fourth international conference on Tangible, embedded, and embodied interaction}, publisher = {Association for Computing Machinery}, address = {New York}, isbn = {978-1-60558-841-4}, doi = {10.1145/1709886.1709959}, pages = {313 -- 314}, abstract = {"Recording Inner Life" is the title of my master's thesis.

Traffic management controllers are tasked with routing repair and clean up crews to clear the incident and often have to do so under time pressure and with imperfect information. To aid their decision making and help them understand how past incidents affected traffic, we propose Traffic Origins, a simple method to visualize the impact road incidents have on congestion. Just before a traffic incident occurs, we mark the incident location with an expanding circle to uncover the underlying traffic flow map and when it ends, the circle recedes. This not only directs attention to upcoming events, but also allows us to observe the impact traffic incidents have on vehicle flow in the immediate vicinity and the cascading effect multiple incidents can have on a road network. We illustrate this technique using road incident and traffic flow data from Singapore.}, 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} } @article{MichelHeidmannLanger, author = {Michel, Antje and Heidmann, Frank and Langer, Constanze}, title = {Design trifft Informationswissenschaft}, series = {Information - Wissenschaft \& Praxis}, volume = {71}, journal = {Information - Wissenschaft \& Praxis}, number = {2-3}, publisher = {De Gruyter Saur}, address = {Berlin}, issn = {1619-4292}, doi = {10.1515/iwp-2020-2072}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:525-26157}, pages = {86 -- 94}, abstract = {Von Januar 2017 bis M{\"a}rz 2019 haben wir, Constanze Langer und Frank Hartmann aus dem Fachbereich Design und Antje Michel aus dem Fachbereich Informationswissenschaften im Rahmen des durch den Stifterverband und die Carl-Zeiss-Stiftung gef{\"o}rderten Curriculumentwicklungsprojekts „Design 0815" zusammengearbeitet.
