Exploring information visualization

Margit Pohl, Sylvia Wiltner, Silvia Miksch
2010 Proceedings of the 3rd BELIV'10 Workshop on BEyond time and errors: novel evaLuation methods for Information Visualization - BELIV '10  
Interactive Information Visualization methods engage users in exploratory behavior. Detailed information about such processes can help developers to improve the design of such methods.  ...  More research is necessary to show whether similar interaction patterns can be found for the usage of other InfoVis methodologies as well.  ...  The exploratory nature of searching for information with the aid of InfoVis methods makes this evaluation process especially difficult.  ...

The Value of Information Visualization [chapter]

Jean-Daniel Fekete, Jarke J. van Wijk, John T. Stasko, Chris North
2008 Lecture Notes in Computer Science  
In this paper we consider information visualization from different points of view, and gather arguments to explain the value of our field.  ...  To convince broader audiences, and also, to understand the intrinsic qualities of visualization is more difficult, however.  ...  For these reasons and others, InfoVis is fundamentally challenging to evaluate [17] .  ...

Workshop Report: Information Visualization–Human-Centered Issues in Visual Representation, Interaction, and Evaluation

Andreas Kerren, John T. Stasko, Jean-Daniel Fekete, Chris North
2007 Information Visualization  
Last but not least, the seminar would not have been possible without the great help of the staff of Dagstuhl Castle. We would like to acknowledge all of them for their assistance.  ...  Acknowledgements We thank all participants at the seminar for the lively discussions as well as the scientific directorate of Dagstuhl Castle for giving us the opportunity to organize this event.  ...  An important issue is that some reviewers might not have expertise in all evaluation methods, and so the InfoVis Conference reviewer database should have more subcategories for evaluation expertise.  ...

Analysing Interactivity in Information Visualisation

Margit Pohl, Sylvia Wiltner, Silvia Miksch, Wolfgang Aigner, Alexander Rind
2012 Künstliche Intelligenz  
These patterns are an indication of strategies users adopt to find solutions. Identifying such patterns may help in improving the design of future information visualisation systems.  ...  Modern information visualisation systems do not only support interactivity but also increasingly complex problem solving.  ...  Furthermore, this work was supported by the Bridge program of the Austrian Research Promotion Agency (project no. 814316) and conducted in cooperation with Danube University Krems, Vienna University of  ...

Casual Information Visualization: Depictions of Data in Everyday Life

Zachary Pousman, John Stasko, Michael Mateas
2007 IEEE Transactions on Visualization and Computer Graphics  
Traditional infovis systems, techniques, and methods do not easily lend themselves to the broad range of user populations, from expert to novices, or from work tasks to more everyday situations.  ...  First, we demonstrate how blurry the boundary of infovis is by examining systems that exhibit many of the putative properties of infovis systems, but perhaps would not be considered so.  ...  ACKNOWLEDGEMENTS The authors wish to thank J. Clawson, C. Plaue, R. Amar, and K. Boehner for their comments on drafts of this paper.  ...
