The area of illustrative visualization is concerned with developing methods to enhance the
depiction of scientific data based on principles founded in traditional illustration. The
illustration community has century-long experience in adapting their techniques to human
perceptual needs in order to generate an effective depiction which conveys the desired
message. Thus, their methods can provide us with important insights into visualization
problems.
In this tutorial, the concepts in illustrative visualization are reviewed. An important aspect here
is interaction: while traditional illustrations are commonly only presented as static images,
computer-assisted visualization enables interactive exploration and manipulation of complex
scientific data. Only by coupling illustrative visualization with effective interaction techniques
its full potential can be exploited.
The tutorial starts with a general introduction into the area of illustrative visualization. The
concept of importance-driven visualization and its applications are presented. Then we proceed with a discussion how traditional abstraction techniques can be applied in an
interactive context using importance-based methods. This ranges from low-level appearance
to smart viewpoint-dependent visibility techniques such as cutaways or exploded views.
Further advanced manipulation strategies are discussed in the third part. The use
deformations to enhance visibility of certain features while providing context or to abstract the
structure of a complex objects through direct interaction with the data is examined. As many
of the presented methods rely on a separation of focus and context, i.e., the important
structures in the data have been identified, the tutorial discusses approaches for selecting
objects of interest in a three-dimensional environment using intuitive sketch-based interfaces.
Since the effectiveness of a user-interface is heavily dependent on the previous knowledge of
the user, the last part of the tutorial examines the concept of layering interfaces based on
user expertise. Finally, the application of illustrative display and interaction techniques for
non-traditional modalities such as mobile devices concludes the tutorial.
