Modelo de representação e orquestrador baseado em nuvem para a contação pervasiva de histórias

Abstract

Internet of Things (IoT) devices are becoming more affordable and part of people’s daily lives. This opens up great possibilities for innovative storytelling experiences, allowing for new forms of consumption, with new types of events and effects, going beyond conventional multimedia. Such narratives would be capable to adapt to the context in which the individual consumer (called interactor) is found, varying according to their own choices. Thus, each interactor would have their own history, as a result of their decisions, informed data, or experiences with other interactors, allowing for a personalized storytelling. In this context, the need for advances in the representation and orchestration of pervasive storytelling is noticeable, taking into account the uniqueness of each individual and their interaction with the physical and virtual environments. This work proposes a conceptual model called PST, which aims to represent stories to be told in a pervasive way, aimed at facilitating the creation of tools for authors and content providers. By modeling the specific domain of pervasive storytelling as a high-level abstractions, the model supports the typical variability of pervasive environments, such as changes in location, device connectivity, proximity between interactors, among others. The model is divided into two main groups: the Aura, with entities responsible for storing all the interactor’s data and history to be used for context awareness and storytelling personalization; and entities of the Narrative Course, responsible for structuring the narration and guiding its presentation. Due to PST’s high-level abstraction, the work proposes, as a proof of concept, a cloud-based presentation machine, capable of interpreting and orchestrating the storytelling as represented through the model, with cloud and edge execution experiments of stories developed by the Digital Media Laboratory (LMD) of the Faculty of Communication at UFJF. The work also points out contributions obtained in feedbacks by professionals in the field of communication, despite the restrictions imposed by the Covid-19 pandemic and the impossibility of fully conducting focus groups.
