|Adapative Visual Computing|
Visual computing uses computer‐supported, interactive, visual representations of (abstract) data to amplify cognition. In recent years data complexity concerning volume, veracity, velocity, and variety has increased considerably. Several adaptive visual computing approaches are discussed in detail. Data‐sensitive navigation for user‐interface elements is presented. The approach normalizes user input according to visual change, and also visually communicates this normalization. In this way, output‐sensitive interactions can be realized. Quantitative and reproducible linking & brushing as integral part of visual analytics is approached through structured brushing, percentile brushes, linked statistics, and change visualization. Multiscale models, e.g., from structural biology, require multiscale dynamic color mapping with sometimes overlapping or contradicting colors. We present a technique, which adaptively, based on the current scale level, nonlinearly and seamlessly adjusts the color scheme to depict or distinguish the currently best visible structural information. Adaptive visual computing is addressing the amplified data complexity through increased scalability. Research challenges and directions are sketched at the end of the talk.
Eduard Gröller is professor at the Institute of Computer Graphics and Algorithms (ICGA), TU Wien, Austria, and adjunct professor of Computer Science at the University of Bergen, Norway. 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 in all areas of visualization He is a scientific proponent and key researcher of the VRVis research center (http://www.vrvis.at/). The center performs applied research in visualization, rendering, and visual analysis. Dr. Gröller has been chief editor of the Journal Computer Graphics Forum (http://wileyonlinelibrary.com/journal/cgf) in the period 2008‐2011. He became a fellow of the Eurographics association in 2009. He is the recipient of the Eurographics 2015 Outstanding Technical Contributions Award.
