Abstract : The work of this thesis aims at contributing to the field of the engineering of interactive critical systems. We aim at easing the introduction of new input and output devices (such as touch screens, mid-air gesture recognition ...) allowing multi-user and multimodal interactions in next generation of aircraft’s cockpits. Currently, development process in the aeronautical filed is not compatible with the complexity of multimodal interaction. On the other side development process of wide spread systems cannot meet the requirements of critical systems. We introduce a generic software and hardware architecture model called MIODMIT (Multiple Input Output devices Multiple Interaction Techniques) which aim the introduction of dynamically instantiated devices, allowing multimodal interaction in critical systems. It describes the organization of information flux with a complete and non-ambiguous way. It covers the entire spectrum of multimodal interactive systems, from input devices and their drivers, to the specification of interaction techniques and the core of the application. It also covers the rendering of every software components, dealing with fission and fusion of information. Furthermore, this architecture model ensure the system configuration modifiability (i.e. add or suppress a device in design or operation phase). Furthermore, moralizing a system reveals that an important part of the interactive part is autonomous (i.e. not driven by the user). This kind of behavior is very difficult to understand and to foresee for the users, causing errors called automation surprises. We introduce a model-based process of evaluation of the interaction techniques which decrease significantly this kind of error. Lastly, we exploited ICO (Interactive Cooperative Objects) formalism , to describe completely and unambiguously each of the software components of MIODMIT. This language is available in an IDE (integrated development environment) called Petshop, which can execute globally the interactive application (from input/output devices to the application core). We completed this IDE with an execution platform named ARISSIM (ARINC 653 Standard SIMulator), adding safety mechanisms. More precisely, ARRISIM allows spatial segregation of processes (memory allocution to each executing partition to ensure the confinement of potential errors) and temporal segregation (sequential use of processor). Those adding increase significantly the system reliability during execution. Our work is a base for multidisciplinary teams (more specifically ergonoms, HMI specialist and developers) which will conceive future human machine interaction in the next generation of aircraft cockpits.
