Abstract

We present a Java-based framework for the easy and on-the-fly creation of algorithm animations. Animations are created by sketching both the objects that should be animated and operations that should be performed on them. The IDEA (Interactive Domain rEcognition and Animation) framework combines the recognition of drawn structures, the interaction with these structures and their animation in order to achieve an effortless and natural creation of animations. The framework itself supports the creation of animations in arbitrary domains through a dynamic plug-in architecture, where so-called domain modules encapsulate all domain-specific semantics. Its application and potential is outlined by the help of three prototypical domain modules for linear lists, Petri nets, and the game Connect-four.
