A Decision-Making Process for Digital Storytelling

Abstract

The method proposed here to determine, in a simplified but still plausible way, the behaviour of the characters participating in a story is based on rules that associate a given situation with a list of different goals. In view of the rules whose situation holds at the current state, each character engages in a decision-making process along three steps: goal selection, plan selection, and commitment. The selection criteria reflect individual preferences originating, respectively, from drives, attitudes and emotions. Four kinds of inter-character relations are considered, which may lead to goal and plan interferences. A prototype logic programming tool was developed to run experiments.
