Importance of Well-Motivated Characters in Interactive Narratives: An Empirical Evaluation

In order for the author to create his/her intended effects using interactive narratives, the user has to be able to understand his/her experience as designed by the author. In this paper, we argue that a key desideratum for interactive narrative frameworks is to model the characters’ motivational consistency during the interaction. This work reports an empirical study for evaluating the importance of using well-motivated characters in interactive narratives. The results demonstrate that inconsistency in the characters’ motivations can confuse the user and affect the user’s expectations and interpretations of the events in the story.
