Interactive drama is more than just a new breed of entertainment software. As different
research projects have shown these systems can also be used for pedagogical and therapeutic
purposes. The goal of these systems is to teach sophisticated problem solving skills by
allowing the user to interact with compelling stories that have didactic purpose.One of the
main attractions of narratives independent of the medium in which they are presented is that
they elicit emotional response in their audiences. They have an affective impact and only
engineers and authors who understand how the emotion system works can create an engaging story
world. This work proposes that an interactive drama based on a model of the user s affective
state should be able to provide a truly immersive user experience.It becomes evident that
research on interactive drama technology especially with emphasis on affective modelling is a
highly interdisciplinary endeavour that draws - and has to draw - from many different
disciplines.
