Read the project description carefully. Questions and comments can be sent to

General information

The purpose of the project work is to get hands on experience and deeper understanding on one specific area of the course. At the same time you will be forced to think on some of the more general issues that are confronted every time a visualization method is developed or used.

To complete the project you will probably need information that has not been discussed on the lectures or in the exercises. Most of the time relevant information can be easily found on the web, course books or in some cases references to articles will be given. If you have problems finding information on the subject please contact the lecturer or the assistant for hints and guidance.

The project work will be valid for one year after the original deadline.

You should do the following

  1. Using your knowledge of human perception, give a summary on how much data you can pack to a certain area and how.

  2. Give a summary of methods of how you can make focus+context work, i.e. how you can see large scale features while ignoring the details, and vice versa.

  3. Visualize a selected data sets applying these methods.
