Topic

Information Visualization

Information Visualization (InfoVis) covers the development of tools for better understanding and analyses of abstract information using the human visual system. Abstract information can normally not be transferred into the physical world. This course gives you an overview of the most important techniques of this research area as well as applications. Covered topics are among others: interaction techniques, visulization techniques (e.g., level of detail, navigation, focus and context, focussing, 2D/2.5D/3D, ...), graph drawing (networks), visualization of hierarchical data.

Assignments

Assignments consists of a brief presentation and an implementation. Each student or student group (consisting of maximal two (2) students) choose a research paper from the list below. Then, the main idea of the paper should be implemented in any programming language. However, you have to implement a working GUI. Each presentation should take around 10 minutes + 3-5 minutes of discussion. This talk should give an overview about the choosen paper at first, and then, you should present your implementation in form of a software demo. The date for this presentation will be at the end of the course (see below).

You should choose a list of three papers in descending order you are interested to implement and email this list to me. I will distribute the papers with the help of your lists and using the "First come, first serve"-principle.
