Authoring Interactive Fictional Stories in Object-Based Media (OBM)

This paper introduces a generic framework for OBM storytelling. Aiming to function as a complete end-to-end reference for authoring OBM narrative content - from conception to realization - it proposes an integrated model that includes the three essential levels: conceptual, technological and aesthetic. At the conceptual level, we introduce a set of abstractions which provide a unified reference for thinking, describing and analysing interactive narrative structures of OBM content. Their recursive nature make our model stand out in terms of its power of expression. These abstractions have direct one-to-one operational counterparts implemented in our production-independent authoring toolkit – Cutting Room. This ensures that any specific story designs conceived within the proposed conceptual model are directly realisable as OBM productions. This isomorphic relationship between the abstract concepts and their operationalisation is another distinguishing aspect of our overall proposition. We have validated the model at the aesthetic level through the production of the interactive film What is Love?, experienced by over 900 people at the media art festival Mediale 2018 in York, UK, and evaluated through a dedicated questionnaire by 94 of them. As the foundations of OBM storytelling have not yet been established, we trust this paper constitutes a significant milestone in its development.
