Développement de méthodes et outils basés sur la réalité augmentée et virtuelle pour l'assistance ou l'apprentissage d'opérations dans un contexte industriel

Abstract : The adoption of digital technologies within industries and the evolution of technologies are opening new perspectives for using augmented reality (AR) and virtual reality (VR). Therefore, those technologies can facilitate the operators’ tasks working on complex industrial systems, either by bringing them some contextualised information in AR or by helping them with VR trainings. Thus they would improve their efficiency. However, integrating these new tools into existing processes of the company remains complex, due to the technologies and the data continuum needed, through the identification of use cases and the associated gains and by the diversity of actors and business experts involved in this process: the expert of the industrial system, the operator, the designer and the computer scientist.In order to develop those different industrial problematics, we first study the state of the art of scientific publications and existing technologies. Then, our research work has proposed a data modelling facilitating content authoring of augmented reality operations on industrial system. This work has also allowed to set up an experimental environment based on an educational production line and an augmented reality application developed thanks to that model.In a second part of this work, and in order to evaluate the efficiency of this technology, we have proposed a methodology allowing to evaluate augmented reality usage for maintenance, repair and operations on industrial systems according to performance, satisfaction and behavioural criteria. We analyse two case studies. They shows that contextualisation of information with augmented reality allows the operator to faster understand the task he needs to carry out than with paper instructions while reducing some kind of errors. Moreover we are proposing some guidelines in order to improve the augmented reality information efficiency. Besides, we are identifying which types of operation are improved with augmented reality. The work is also describing the rendering device influence on the use of augmented reality.Finally, and based on the augmented reality modelling, we are proposing an ontology allowing to unify content authoring of augmented and virtual reality so as to train or guide operator in their tasks. We are studying the use of this ontology for exploiting others data and company knowledge, as maintenance. This ontology is used for training scenarios in industrial environment and for guiding operator during their work.
