Visualizations represent a means to communicate data and analysis results. Our research at the Chair for Data Analysis and Visualization is driven by real-world problems and intends to bring the human capabilities and perception together with computer algorithms, using visualization. Thereby, we face the key challenge of how to visually communicate data to the human. A common assumption of visualization researchers is: the more abstract a representation is, the harder it is to interpret for the human, in particular if not trained in reading visualizations.
In cooperation with the “GI-Fachgruppe Be-Greifbare Interaktion”, the HCI group at the University of Stuttgart organized the annual Inventors-workshop with the topic: Using Physiological Sensing for Embodied Interaction. In the workshop, we introduced the basic concepts for sensing of human muscle activity accompanied by a refreshing Keynote from Leonardo Gizzi. We provided a basic explanation of how physiological sensing works, introduced how it can be technically realized, and showed different applications and usage scenarios.
Together with the Human-Computer-Interaction Group of the University of Stuttgart, the SFB-TRR 161 organized a Winter School in February at Söllerhaus (Kleinwalsertal, Austria). During this three days seminar several visual computing scientists from the University of Stuttgart and the University of Konstanz could intensify their scientific cooperation, exchange their knowledge and talk about their new findings in their projects work. All of the PhD students gave talks and did some demonstrations.
During this winter, I spent the last three months at the Data Analysis and Visualization Group led by Prof. Dr. Daniel Keim at the University of Konstanz. During this stay I had the opportunity to meet many researchers who work in visualization and visual analytics in multiple domains and pursue my research work.
Since October 2015 I have been in contact with Prof. Oliver Deussen, who since 2010 has been developing the e-David, a robotic Drawing Apparatus for Vivid Interactive Display, at the University of Konstanz. Subsequent to the first encounter at the Massachusetts Institute of Technology (MIT), I visited Prof. Deussen and his team at their lab in Konstanz, to continue to discuss and re-evaluate the potential use of the robot from an artistic and creative perspective.
Kuno Kurzhals is a visualization scientist at the Visualization Research Center of the University of Stuttgart (VISUS) with special focus on video visualization and evaluation methods in combination with eye tracking. His research is associated with the SFB-TRR 161 where scientists whant to establish quantification as a key ingredient of visual computing research. In this video interview he talks about the challenges and aims of his activities and explains some of his visualization results.
At the end of last month, Michael Klein from 7reasons, Vienna, visited the Visualization Research Center of the University of Stuttgart (VISUS). Within the Lecture Series “Visual Computing“ carried out by the Universities of Stuttgart and Konstanz within the research project SFB-TRR 161, he gave an enlightening talk about the application of computer graphics for cultural heritage preservations.
Franz Hahn is a PhD student in the Multimedia Signal Processing Group of Prof. Dietmar Saupe at the University of Konstanz. During his project activities in the SFB-TRR 161 he is concerned with the topic of image and video quality assessment. Using Eye Tracking he aims to develop a predictive model that improves the quality of images by keeping the data size the same.
For SIGGRAPH Asia 2016 more than six thousand people from all over the world came to Macao. For four days, the attendees of the largest annual conference in computer graphics and interactive techniques in Asia, exchanged their latest and current results in research, projects and developments in various related areas.
“What we aim for in the end is some sort of mechanism, that tells us, whether the users understood, what they were looking at.”
Jakob Karolus is a researcher at the Institute for Visualization and Interactive Systems at the University of Stuttgart working in the field of Human-Computer Interaction. Within the project SFB-TRR 161 “Quantitative Methods for Visual Computing” he wants to find out how different visualizations influence the eyemovement patterns of people.
