This thesis presents the implementation of the AI model and the behaviors of the interactive art installation and guidance system Source.Code developed by Ars Electronica Futurelab. The AI model is built on a hybrid control system with a rule hierarchy tree describing the intelligent characters of the installation. This thesis describes the entire real time AI model implementation from the decision model down to the navigation system and the collision detection. The thesis also positions the AI part of Source.Code in an interactive storytelling context.
