Making narrative interactive promises to add a new depth and richness to the act of storytelling. It will allow us to experience story at a new level, more profoundly affecting us than ever before. But to do this we need to understand how a viewer can participate in a drama in interesting and engaging ways without disrupting the plot-- which is the essential structure that transforms a mere sequence of events into a story. This thesis describes an approach to interactive narrative that-divides narrative into levels; the plot level which rep-resents the high level goals, intentions, and events of the story, and the presentation level representing the geometry, motion and camera which produces the images seen by the viewer. Today's immersive interface technology pro-vides a seamless and compelling link between the viewer and the presentation level. But the link between the plot level and the presentation level remains unexplored. This document describes techniques as well as a theory for seamless integration of transitions (the plot's influence on the camera) and the manipulation of staging (the plot's influence on the geometry and motion) into interactive, immersive narratives. By introducing these techniques while allowing the viewer to influence the presentation, a new method and vocab
