These questions, which at first glance might seem dissociated, arise from a general problem that aims at defining the best strategy to inform people on the temporal evolutions of a dynamic system (here the vehicle or the writing gesture) within a specific cognitive context (in the situation of pedestrians, conductors or writers). The sound represents an incontestable sensory modality to address such questions. In fact, sounds are intrinsically linked to time and therefore perfectly adapted to the expression of dynamic characteristics. Moreover, sounds bring additional information about things that are outside our field of view in a natural way, hence revealing the invisible.

The “MetaSound” project proposes a genuine investigation of fundamental questions for an optimal use of sounds in the context of augmented reality by the means of two problems that are both rich and challenging because of the imposed constraints and the industrial and societal consequences that they induce:

The scientific milestones of the Metason project are based on three fundamental questions:
structure metason
To exhaustively treat these questions, a strong multi-disciplinary interaction is needed. The consortium gathered around the MetaSound project unites the necessary competences, hereby enabling a formal and original approach to the problem by taking into account human factors and by using a genuine language of sounds constructed thanks to the ductility of digital synthesis and the semiotics of sounds.
The project is divided in six strongly interacting tasks, which susceptibly will lead to theoretical, technical and applied advancements. In addition to the coordination task, two main tasks concern the applications of the project and will be validated by the realization of a sonified, rolling prototype (car application) and a prototype to assist dysgraphic persons.
Two more fundamental tasks will establish original models and methods to characterize the dynamic contents of the sound signals and their reproduction by synthesis. They will allow the construction of sound metaphors and the conception of high-level control processes that act on attributes linked to sensations.
The last task is strongly technological, since it concerns the realization of a real-time synthesis platform of spatialized sounds controlled by external variables and specific cognitive scenarios to the intended applications. It will constitute a very general tool disposed for dissemination in any community linked to augmented reality and applications to interactive sounds (cinema, video games, …).
