Evaluating directorial control in a character-centric interactive narrative framework

Interactive narrative allows the user to play a role in a story and interact with other characters controlled by the system. Directorial control is a procedure for dynamically tuning the interaction towards the author's desired effects. Most existing approaches for directorial control are built within plot-centric frameworks for interactive narrative and do not have a systematic way to ensure that the characters are always well-motivated during the interaction. Thespian is a character-centric framework for interactive narrative. In our previous work on Thespian, we presented an approach for applying directorial control while not affecting the consistency of characters' motivations. This work evaluates the effectiveness of our directorial control approach. Given the priority of generating only well-motivated characters' behaviors, we empirically evaluate how often the author's desired effects are achieved.
