Group leader: J.J. van Wijk

Jarke J. van Wijk received a MSc degree in industrial design in 1982 and a PhD degree in computer science in 1986, both from Delft University of Technology, both with honours.

He worked at a software company and at the Netherlands Energy Research Foundation ECN before he joined the Eindhoven University of Technology in 1998, where he became a full professor of visualization in 2001.

He is cofounder of MagnaView BV, a company that aims at providing visual tools for large datasets, and is since 2005 vice-president scientific affairs.

His main research interests are information visualization, visual analytics, flow visualization, and mathematical visualization. He has (co-)authored more than 100 papers, including many papers in prestigious venues such as ACM SIGGRAPH and IEEE Visualization. 

He has been paper co-chair for many international conferences in the area of visualization (including IEEE Visualization and IEEE InfoVis, and IEEE PacificVis 2010).

In 2007 he received the IEEE Visualization Technical Achievement Award for his work on flow visualization, and he received the Henry Johns Award 2009.

The research

The mission of the Visualization (VIS) chair is the development of methods, techniques and tools that enable people to obtain insight in data via interactive computer graphics. Data Visualization exploits the unique capabilities of the human visual system to detect patterns and trends in imagery.

The central research question is how data should be presented such that this process is most efficient and effective. Our approach in this area is characterized by the application of know-how from 3D computer graphics and geometric modelling and by an experimental approach involving fast prototyping, close cooperation with end users, and validation in practice. Scalability of methods is a key issue.


Within the large field of Visualization we currently specialize in the following areas:

Information visualization
We study how large amounts of abstract data, such as trees and networks, can be visualized. Typical use cases are the visualization of the contents of a computer hard disk and the visualization of the structure of a large software system.

3D interaction and virtual reality
Visualization requires often interaction with 3D data and objects for interrogation and navigation. In cooperation with CWI we study how affordable desktop Virtual Reality systems (hard- and software) can be designed to simplify these tasks.

Scientific visualization
Scientific visualization concerns data from simulations and measurements, defined over geometric spaces. Within this area we study the visualization of fluid flow and architectures for flexible visualization.

Thesis projects

Thesis projects are possible in each of these areas. The exact topic of the thesis project is defined depending on the interest and skills of the students.

Sequoia View

Ever wondered why your hard disk is full? Or what directory is taking up most of the space? When using conventional disk browsing tools, such as Windows Explorer, these questions may be hard to answer. With SequoiaView however, they can be answered almost immediately. SequoiaView uses a visualization technique called cushion treemaps to provide you with a single picture of the entire contents of your hard drive. You can use it to locate those large files that you haven't accessed in one year, or to quickly locate the largest picture files on your drive.
