Technologies logicielles de la modélisation, de la simulation et de l'interaction multisensorielles instrumentales pour la création

摘要

The presented works have firstly questioned the possible inter-relations between physics-based modelling and simulation on the one hand, and creation and creativity on the other. More specifically, the possibility and fundamental interests of rooting creative activities onto physics-based modelling have been considered.This theme was approached from a Computer Sciences perspective, through the invention and the design of a new family of software environments aimed at creation with masses-interactions physics-based networks. In particular: GENESIS for musical creation, and MIMESIS for movement and computer graphics animation.These software environments empower the artist with innovative and complete creation processes, centred on physical modelling activities.Each and all of these environments are characterized by a specific “software environment paradigm”: dedicated features, software architecture specificities, adequate and necessary human-computer interaction means (interfaces and languages), and particular usage protocols (in our case: modelling and creative processes).These elements have been situated in the scientific and technological history of computer creation tools, and in the state of the art of the various concerned scientific domains. This work has in particular led to analysing the properties of masses-interactions physical networks (modularity, generic potential, calculability, usability, …), in relation with other categories of algorithms, models and formalisms used nowadays to address human sensori-motor skills. It also accompanied the demonstration that the building of physical models by an artist can be deeply relevant. This relevance lies in the qualities of the phenomena that are finally generated, but also, which is more original, and probably more essential, in the modelling/creation processes themselves.Finally, the works have been extended to various other axes: contributions to synchronous real-time simulation architecture and software for multisensory interaction, including force-feedback, sound, and image, by means of physics-based simulation; experimental modelling works; contributions to the evolutions of the formal basis of the physics networks paradigm; contributions to graphical representation of punctual movements, etc.These past works and the achieved results altogether lead to introduce new research perspectives, which we name software technologies of multisensory instrumental interaction, with, as a far end view, the foundation of a new “science of the multisensory computer” and the possibility of a “multisensory art”.
