Contextual information plays a crucial role in nearly every conversational setting. When people engage in conversations they rely on what has previously been uttered or done in various ways. Some nonverbal actions are ambiguous when viewed on their own. However, when viewed in their context of use their meaning is obvious. Autonomous virtual characters that perceive and react to events in conversations just like humans do also need a comprehensive representation of this contextual information. In this chapter we describe the design and implementation of a comprehensive context model for virtual characters.
