Information Visualization
In the area of Information Visualization (InfoVis), we research novel visualizations techniques and develop new tools for different domain user groups. On this web page, we provide an overview regarding visualization techniques (together with their effectivity and usefulness) as well as regarding specific solutions for several application areas.Information Visualization for Specific Applications
Specific application areas require special visualization solutions. Typically, the development process of a visualization tool for specific domains is an interdisciplinary task: visualization experts and the future users should work closely together in order to guarantee useful and applicable results. These should also be carefully evaluated.Projects
| Visual Analysis of Wine Tasting Notes and Wine Attributes Project partner is Carita Paradis from the School of Language and Literature at LNU, Sweden (partly funded by Innovationsbron under grant 800255). Describing sensory perceptions, such as taste, is a challenging task. A suitable visualization tool for such sensory descriptions would help several groups of users. On the one hand for a customer, the visualization of the taste or flavor of a specific wine would help him/her to choose the right one according to own individual preferences. On the other hand for a language researcher, it could be interesting to understand how people talk about such sensory perceptions, what types of metaphorizations or lexical resources exist, etc. This is usually done in so-called wine tasting notes written by wine expers. We are developing novel visualization approaches for both groups of users. [research in progress] |

Visualization of GeoAudio Notes Research partner is the CeLeKT group at LNU, Sweden. The aim of this research is to explore novel techniques and methods to visualize the content of voice notes that will be placed in maps using GPS coordinates, and visualizing the semantical, temporal, and spatial relations between the notes.

| Visualization of Particle Interactions Project partner is the International Research Training Group on the Visualization of Large and Unstructured Data Sets at the University of Kaiserslautern, Germany. Interaction between particles in so-called granular media, such as soil and sand, plays an important role in the context of geomechanical phenomena and numerous industrial applications. In this research projects, we develop a novel 2D approach for the visualization of simulation data. Our visualization approach supports visualization on the micro scale level, based on a discrete element method, as well as visualization on the macro scale level, discretized by finite elements.

Visualization for Analyzing Geographic Information Part of the GEOGRAPH project at TU Vienna, Austria (funded by the FWF under grant P14462). Aim of this project was the exploration of methods in order to collect, to analyze, and to visualize geographic information with the help of hierarchies of plane graphs. Such graph hierarchies are called graph pyramids and are suited as a structure for storing and retrieving geographic information. [completed project | performed at the TU Vienna, Austria] |
Information Visualization Techniques and Evaluation
The development of new visualization techniques is the backbone of scientific progress. Thus, it is very important to work on basic and/or challenging problems, for example, to improve the exploration of complex network or to show complex hierarchies. Especially in Information Visualization, the development of novel interaction techniques is of great importance.Projects
| Visualization of Network Graphs We have several research partners for this topic, e.g. the Network Analysis Group at the IPK Gatersleben, Germany. The visualization of large networks plays an important role in many application areas, such as in bioinformatics, social network analysis, or software engineering. Our general aims are more related to the interacive exploration of huge networks and to the integration of additional information into networks. Thus, our research outreaches the pure drawing of graphs. [research in progress] |

Collaborative Information Visualization Project partner is the Research Group on HCI and Visualization at the University of Kaiserslautern, Germany. There is only little research in collaborative InfoVis. Collaboration can take place asynchronous (Asynchronous Collaborative Information Visualization - ACIV) or synchronous (Synchronous Collaborative Information Visualization - SCIV) as well as distributed or undistributed (local). Our intention is the development of an undistributed or distributed SCIV solution. In case of local SCIV, tiled high-resolution display technology should be used and appears to be the ideal platform for local collaboration of domain experts. Both directions require individual research and the development of effective interaction techniques. [research in progress] |
Visual Analytics
Visual Analytics is an emerging new research discipline developing technology to make the best possible use of huge information loads in a wide variety of applications. The main idea is to appropriately combine the strengths of automatic data analysis with the visual perception and analysis capabilities of the human user. More information and interesting discussions within this new field can be found on the VA Community website.Projects
| VisMaster The VisMaster project consists of different research groups from nine different countries. With VisMaster, we want to push the limits of today's Visual Analytics. To achieve this goal, we formed a Coordination Action to join European academic and industrial R&D excellence from several individual disciplines, forming a strong Visual Analytics research community. The project is divided into an array of thematic working groups that focus on advancing the state of the art in Visual Analytics. Specifically, the working groups will join excellence in the fields of data management, data analysis, spatial-temporal data, and human visual perception research with the wider visualisation research community.
