[Show abstract][Hide abstract] ABSTRACT: Interactive storytelling systems are applications to generate and dramatize interactive stories. The main challenge to such systems is the generation of coherent stories while users are watching and interfering with what is happening. In an interactive TV environment, quality and diversity of narratives are crucially important objectives. In addition, new requirements related to comfort in user interaction, responsiveness and scalability have to be taken into account. In this paper, we present a model for interactive TV storytelling to cope with these requirements. The model was implemented in a new version of the planning-based interactive storytelling system Logtell.
[Show abstract][Hide abstract] ABSTRACT: Interactivity, coherence and diversity of the stories are key issues for the development of interactive storytelling systems. When stories are to be told via interactive TV, special interaction methods are also necessary in order to cope with high responsiveness requirements. In this paper, we describe the ex-tension of the interactive storytelling system Logtell we have developed to run in an interactive TV environment. Planning algorithms have been applied to provide coherence and diversity for the stories at levels of both plot composi-tion and dramatization. A new architecture was designed to combine these algo-rithms with special interaction methods incorporated to achieve high respon-siveness.
[Show abstract][Hide abstract] ABSTRACT: Interactive storytelling is a new form of digital entertainment that brings together techniques and tools for the creation, visualization and control of interactive stories through electronic means. One of the main challenges of interactive storytelling is the generation of stories that are both coherent and interesting, while providing means to allow the user to interact with the story. On the other hand, user's intervention should not violate the rules of the chosen genre, leading to unlikely developments. Another problem arises when storytelling environments require high responsiveness, as is the case in interactive TV. The fact that storytelling systems are usually very CPU intensive should not affect responsiveness. This paper describes a model to deal with these requirements, which has been implemented over a previous version of Logtell, a logic-based tool for interactive generation and dramatization of stories.
