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?
