TopicInteractive Digital Storytelling: From Artificial Intelligence to Narrative Intelligence

 

Abstract:

The field of Interactive Digital Storytelling (IDS) has emerged since 15 years ago, when researchers and practitioners realized that in virtual environments, letting a user have a strong influence on events while preserving a good narrative experience was an interesting and difficult problem, which could not be solved by classical software approaches.

Two Artificial Intelligence (AI)-based approaches quickly became prominent to tackle the problem: autonomous agents and planning. The autonomous agents approach consists of developing rich story characters who, by interacting with each other, would produce a story. However, autonomous characters rarely produce a meaningful story because a story cannot be reduced to its characters. The planning approach consists of defining a story-end and letting the system calculate a path towards that end, while taking into account the user’s choices (via re-planning techniques). However, planning techniques seek the shortest path towards an end, which is different from the logic of stories: it is the path itself that is interesting and the path is rarely quick and easy. Both autonomous agents and planning lack something when it comes to describing a narrative.

Therefore, it was necessary to propose a third approach: the modeling of some key narrative properties to complement classical AI approaches. In this paper, we will review how various researchers have investigated narrative models for IDS. We will present our own approach in the domain. It will be demonstrated in a fully implemented IDS game. Finally, the role of narrative models in AI in general will be discussed.
