Interactive Visualization and Data Analysis Group (Former Research Group)

Vision and Research Strategy

The primary objective of this research group is the creation of novel algorithms, metaphors, and architectures for the interactive visualization and analysis of large and complex data sets. With today's simulations and experimental measurements generating enormous amounts of complex data, existing visualization techniques often overburden the scientist and do not scale well to current and upcoming hardware architectures. To overcome these limitations, our research focuses on three main principles:

  • Firstly, the development of novel primitives, methods, and metaphors to effectively map large and complex data to human-readable representations.
  • Secondly, the realization of efficient and scalable implementations that take full advantage of the massive parallelism available in current and upcoming systems to achieve interactive performance of the aforementioned novel techniques and existing approaches.
  • Thirdly, the extension of these systems to take advantage of all available computing and visualization resources on data centers with large high-resolution visualization systems, on the ubiquitous desktops, and on the smallest mobile hand held devices, to give experts and end users effective and efficient access to their data wherever they are.

To give a broad range of fellow researchers the ability to benefit from this group's developments, and to allow us to receive feedback on the practical use of our research, source code of all IVDA projects is released as open source. Good examples of this practice are the ImageVis3D and ImageVis3D Mobile applications. Both are being downloaded and used by thousands of users worldwide and have been shown to be effective in a number of areas.

Composition of Group

The Interactive Visualization and Data Analysis Group headed by Jens Krüger was founded in August 2009 in the Cluster of Excellence. At present, the group consists of two PhD students, Georg Tamm and Jürgen Grüninger. A third PhD position funded by the Intel Visual computing institute is currently being filled.
