Part 4: Guided Navigation and Exploration (Stefan Bruckner)

Abstract

In particular in the context of applications targeted at users with a limited technical background, it can be beneficial to constrain the users' freedom and instead provide automated guidance and suggestions to simplify the interaction. This part of the tutorial will focus on guided navigation and exploration strategies which exploit additional information in order to fully or semi-automatically assist the user in specifying relevant visualization parameters. This includes common settings such as the viewpoint, clipping planes, transfer functions, but also extends to the choice of the visualization technique itself. Such approaches frequently rely on additional knowledge and we will discuss different strategies for obtaining the required information. Finally, we will review approaches for integrating such guidance into existing workflows with a particular focus on medical and biological applications.
