In this field, while many researchers have focused on the proper balance between plot-based narratives (how classical narrative structures from literature can be transferred to shape interactive stories) and character-based narratives (how autonomous characters coordinate to create emerging stories), there has been little concern on the integration of proper temporal structures in narratives and their validation in terms of story legibility. The temporal structure in a narrative (the order in which the narrative units of a story are presented) obviously has a considerable impact on the conveyance and understanding of a sequence of events. Storytellers (and cinematographers) build sequences of story primitives to manipulate the mental and emotional state of a viewer [Branigan92, Bordwell85]. Therefore offering the ability for authors to easily manipulate the temporal structures and generate variations of arrangements opens great perspectives in terms of creativity. However the straightforward formalization of temporal structures from narratives does not guarantee the proper comprehension for viewers, and requires a validation. The Event-Indexing Situation cognitive model seems to offer the proper framework to establish relevant metrics of comprehension (as shown in [Cassel12]). The objective of this PhD is propose computational temporal structures for authors to model complex interactive stories in a real-time 3D environment. The work is decomposed in : (i) analyzing temporal discourses in movies to extract narrative structures and models following the line of multimodal film analysis techniques [Bateman12] (ii) proposing a formalization of temporal structures in a computational framework to generate temporal variations of a same story, and designing metrics for their validation using cognitive theories [Cassel12] (iii) integrating these structures in a 3D interactive framework for narratives, performing a proper integration of cinematographic aspects. Recent advances in autonomous character control and automated cinematography techniques offer reliable and high-level means to orchestrate and convey complex behaviors involving many virtual characters [Cavazza10]. This considerably reduces the process of linking logical story units to their 3D animation counterparts and camera settings [Christie09]. The work will rely on existing frameworks for 3D interactive storytelling developed in our Mimetic research team. For this research topic, the IRISA Mimetic team searches for an excellent PhD candidate which a strong interest in virtual 3D environments (interaction, computer animation, virtual characters), good programming skills, the ability to easily manipulate narrative concepts and a good knowledge in cinematographic techniques and discourse.
