Visualizations support the comprehensibility of data in all sectors. The goal is not only to produce images from data, but above all to provide new insights into this data. We focus our research on new interactive visualization methods that support experts from different fields in the exploration, analysis and presentation of complex data. In doing so, we focus on those problems that cannot be solved with purely automatic methods.
The data types we mainly work with are spatial 3D data derived from simulations or image acquisition techniques, large geographic data, abstract data and spatio-temporal data from tracking techniques.
In our research work we have successfully solved many problems related to the understanding of time series data, animal or human trajectories, flow data, GIS data, infrastructure data and much more. In particular, we focus on: quantitative visual analysis, visualization for heterogeneous simulation data and large-scale geovisualization.
In the field of quantitative visualization we are working on making purely qualitative analyses quantifiable through special extensions for existing visualization programs and concepts. In this way, we are responding to the needs of many areas, such as medical diagnostics, automotive simulations or general decision-making processes for which the analysis results must be made comprehensible and reproducible.
For the visualization of heterogeneous data, such as those frequently encountered in medicine or simulations, we create systems that reconcile, register and analyze data from different sources and in a wide range of resolutions. We also develop complex data models and corresponding analysis techniques that enable the analysis of large collections of time series or surface data.
For the visualization of enormous amounts of data, as they occur with geodata from large terrain models or 3D data from time-dependent simulations, we have developed interactive large-scale 3D visualizations, which are particularly suitable for use in complex infrastructure projects: The possibility of combining data sets from various planning disciplines in one system, as well as showing further simulation results in their actual context, makes planning projects and information understandable for experts as well as laymen.
In our first systematic audience study, "A Comparison of Radial and Linear Charts for Visualizing Daily Patterns", published in IEEE Transactions on Visualization and Computer Graphics and presented at IEEE VIS, we investigated the advantages and disadvantages of radial charts for visualizing periodic time-dependent data. Since there has been no systematic discussion of radial representation of periodic day patterns in the scientific literature, our research results were able to define visualization guidelines for the first time.
There are numerous scientific examples where the movement and behaviour patterns of people, animals or even vehicles are recorded. Together with the spatial and temporal context, the resulting trajectories represent a complex, heterogeneous set of data. In order to be able to present these data in interactive visualizations in a meaningful way, a hybrid approach combining automatic and interactive analyses is often required: Our innovative interactive visualization tools, combined with machine learning and deep learning techniques, enable efficient analysis in this case. Our expertise includes behavioural research in a number of contexts, for example in the context of T-Maze experiments.
GEARViewer is the result of many years of research on the visualization of complex infrastructure projects and is based on our high-performance visualization framework Aardvark. The tool, developed together with project partner Geoconsult Wien ZT GmbH, allows the interactive exploration of extensive geographical areas as well as the analysis, simulation and presentation of the effects of large-scale infrastructure buildings on urban and rural environments. For example, a dynamic information and guidance system on the main access roads to Munich Airport was planned and tested using GEARViewer.
