Plan • Qu’est-ce qu’une histoire interactive? • Le « paradoxe »… • Le point de vue Drame Interactif • Les approches • Une approche! • La fin du paradoxe... • Le début d’une nouvelle écriture! LINC - Equipe "Technologies & Communications"
histoire vs récit Définition histoire interactive = le lecteur modifie l’histoire LINC - Equipe "Technologies & Communications"
Le « paradoxe » • Narration = suite d’événements arrangés par un auteur • Interaction = événements décidés par le lecteur • Qui fait quoi?? LINC - Equipe "Technologies & Communications"
Le drame interactif • Drame = le récepteur perçoit directement les événements de l’histoire • Exemples: théâtre, cinéma, drame radiophonique, BD, jeu vidéo • Drame interactif: le récepteur est un personnage (sur ordinateur...) LINC - Equipe "Technologies & Communications"
Les approches • Personnages intelligents • Jeux Vidéos (Creatures, B&W, Sims, etc.) • « Narrative characters » (Univ. Teesside) • Emergence... • (multi)linéarité générique • « Plot points » (CMU, Inesc) • Succession de scènes (B. Majerko, Facade) • Modèle de Propp (Darmstadt) • Simulation • Planification (Liquid Narrative, N. Sgouros) • Description structurale (U. Aalborg, IDtension) LINC - Equipe "Technologies & Communications"
