AI-based animation for interactive storytelling

چکیده
In this paper, we describe a method for implementing AI-based animation of artificial actors in the context of interactive storytelling. We have developed a fully implemented prototype based on the UnrealTM game engine and carried experiments with a simple sitcom-like scenario. We discuss the central role of artificial actors in interactive storytelling and how real-time generation of their behaviour participates to the creation of a dynamic storyline. We follow previous work describing the behaviour of artificial actors through AI planning formalisms, and adapt it to the context of narrative representation. The set of all possible behaviours, accounting for various instantiations of a basic plot, can be represented through an AND/OR graph. A real-time variant of the AO* algorithm can be used to interleave planning and action, thus allowing characters to interact between themselves and with the user. Finally, we present several examples of short plots and situations generated by the system from the dynamic interaction of artificial actors.

A Conversational Avatar Framework for Digital Interactive StoryTelling
Digital Interactive Storytelling (DIS) is a relatively novel area of computer entertainment which aims at investigating interactive applications capable of generating consistent, emergent and rich stories. To provide new solutions for DIS, we have proposed a novel multi-agent DIS framework, DIEGESIS, which includes agents' coordination and new planning and replanning solutions for DIS. A natura...

This thesis presents the Interactive Storyteller, a ‘story domain’-independent multi-user interface for AI-based interactive storytelling. Up until now, users of our storytelling framework, which uses the emergent narrative approach, had no influence on how the storyline developed. In the current research we aim to offer users a social setting for AI-based interactive storytelling. Existing AIb...
متن کاملAI Characters and Directors for Interactive Computer Games
We are creating an environment for investigating the role of advanced AI in interactive, story-based computer games. This environment is based on the Unreal Tournament (UT) game engine and the Soar AI engine. Unreal provides a 3D virtual environment, while Soar provides a flexible architecture for developing complex AI characters. This paper describes our progress to date, starting with our gam...
