Directorial Control in a Decision-Theoretic Framework for Interactive Narrative

Computer aided interactive narrative has received increasing attention in recent years. Automated directorial control that manages the development of the story in the face of user interaction is an important aspect of interactive narrative design. Most existing approaches lack an explicit model of the user. This limits the approaches' ability of predicting the user's experience, and hence undermines the effectiveness of the approaches. Thespian is a multi-agent framework for authoring and simulating interactive narratives with explicit models of the user. This work extends Thespian with the ability to provide proactive directorial control using the user model. In this paper, we present the algorithms in detail, followed by examples.
