As part of the CS-Colloquium at University of Vienna, the Visualization and Data Analysis group invites Professor Eduard Gröller from Vienna University of Technology to talk about
"Visual Computing -- Quo Vadis”
When: 9. October 2013 at 15:00
Where: Hörsaal 3, Faculty of Computer Science, University of Vienna
Währinger Straße 29, 1090 Wien
Abstract: Data Visualization uses computer-supported, interactive, visual representations of (abstract) data to amplify cognition. Visualization is an essential part of Visual Computing which in turn is concerned with the acquisition, representation, processing, analysis, synthesis, and usage of visual information. The talk discusses various challenges in visual computing. In recent years data complexity and variability has increased considerably. This is due to new data sources as well as the availability of uncertainty, error and tolerance information. Visual steering supports decision making in the presence of alternative scenarios. Multiple, related simulation runs are explored through branching operations. To account for uncertain knowledge about the input parame ters, visual reasoning employs entire parameter distributions. This can lead to an uncertainty-aware exploration of (continuous) parameter spaces. Multivariate and heterogeneous data call for visual analysis and knowledge-assisted interaction. To cope with intensified scalability issues and distributed processing approaches, advanced strategies are required like comparative visualization, integrated views and inclusion of fuzzy sets in the visualization process. Examples concerning the aforementioned topics will be presented in the talk.
Short Biography: Eduard Gröller is professor at the Institute of Computer Graphics and Algorithms (ICGA), Vienna University of Technology. In 1993 he received his PhD from the same university. His research interests include computer graphics, visualization, and visual computing. He is heading the visualization group at ICGA. The group performs basic and applied research projects in all areas of visualization. Dr. Gröller has given lecture series on visualization at various other universities (Tübingen, Graz, Praha, Bahia Blanca, Magdeburg, Bergen). He is a scientific proponent and key researcher of the VRVis research center.
