Reaching Cognitive Consensus with Improvisational Agents

A common approach to interactive narrative involves imbuing the computer with all of the potential story preauthored story experiences (e.g. as beats, plot points, planning operators, etc.). This has resulted in an accepted paradigm where stories are not created by or with the user; rather, the user is given piecemeal access to the story from the gatekeeper of story knowledge: the computer (e.g. as an AI drama manager). This article describes a formal process that provides for the equal co-creation of story-rich experiences, where neither the user nor computer is in a privileged position in an interactive narrative. It describes a new formal approach that acts as a first step for the realtime co-creation of narrative in games that rely on the negotiated shared mental model between a human actor and an AI improv agent.
