Back-Leading through Character Status in Interactive Storytelling

A key challenge in computer-based interactive narrative is the conflict between user agency and authorial control of the story quality. Valuable lessons can be learned from improvisational and especially interactive theatre, where various narrative and interactive strategies have been developed to engage users in the process of co-creating the story. In this paper, we focus on the use of character status and status shifts. Specifically, we present and illustrate a computational model of status shifts based on the cognitive semantics theory of force dynamics.
