A Sketch-Based Tool for Authoring and Analyzing Emergent Narratives.

We present a real-time tool for authoring and analyzing emergent narratives (EN) built using a possible worlds EN framework. The tool works by reducing the emergent narrative into a discrete tension space (TS), based on possible conflicts between characters, and actions treated as movements in the space. The shape and structure of the TS enables an analysis of higher-level narrative and character properties. Likewise, TS can be constructed through a sketch-based interface, that enables the creation of context-free emergent narrative systems.
