  • Teaching evaluation (Online Lehrevaluation) now open, please fill it under:

  • The selection period for talks has concluded and all papers have been now assigned.
  • Each student needs to give a short scientific presentation of 14 minutes (+ 3 minutes for questions) on the assigned paper. The presentations should be in English, and can use any desired template. For your convinience, we offer the ICG slides template (but its use is not compulsory).
  • For a more interesting discussion, the students should take a look at the papers that will be presented in each session (see the Agenda section).

Photos, drawings, maps, diagrams, pictograms, cartoons, text, formulas, PowerPoint presentations...: Our sense of sight is the most important information input channel into our consciousness. Whether representational or abstract information, a suitable form of visualization enables us to grasp the meaning of information faster and more fundamentally than, for example, when we just hear the information.

The lecture will explore the background of information visualization from the perspective of computer science, psychology, neuroscience, and art. We will deal with questions like

  • What is information?
  • What forms of information exist?
  • How does visual information enter our consciousness?
  • How can information be visualized?
  • What forms of visualization are there?
  • What is attention?
  • How is attention aroused visually?
  • How is visual information stored in the brain?

The course is explicitly aimed at students of ALL disciplines and is also offered as a key qualification in the lecture pool "interdisciplinary qualification".

Additionally, the participants of this lecture will be given the opportunity to obtain a certificate for their acquisition of skills in the areas of media, information and digital transformation: the Digital Literacy Certificate (Digital Literacy Zertifikat).
