Conception et réalisation d'un nouvel outil à réalité mixte et retour d'effort pour toucher et créer les nanomondes : NanoManipulateur Multisensoriel

Abstract : The recent introduction of virtual realities into scientific data processing tools inaugurates a major turning in the history of the man machine interfaces, by allowing a real-time interaction with virtual spaces. ln parallel, the emergence of nanosciences requires the installation of innovative tools which, beyond the measurement and classical data display, will allow action and understanding at a scale where physical phenomena are singular and typically intangible. This work aims to develop of a nanomanipulator, an instrumental interface of augmented reality based on the coupling of an Atomic Force Microscope, a simulator and a multisensory platform. This nanomanipulator conforms like a real tool allowing to interact naturally and directly with the environment of the nanoworld. The multisensoriality is allowed by the real-lime rebuilding of a mixed space (real and virtual), energetically and dynamically coherent, where the user can interact with force feedback, animated images and sounds. Reality is increased thanks to the insertion of virtual mass-point physical models, interacting conjointly with the user and nanoscene. The modularity and the opening of this instrument are presented, besides the issues induced by the scaling and by the technological and modeling systems. The teaching impact of such a device, for the formal training of intangible physical phenomena, within a practical teaching framework in nanophysic, constitutes a first evaluation of the tool. Its potential for research was highlighted through some applications of determination of real nanometric situations through recursive modeling and sensory comparisons with their virtual counterparts.
