Abstract
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.IEEE Visualization 2007 Tutorial Page: http://vis.computer.org/vis2007/session/tutorials.html#t7
