Vers une communication humain-machine naturelle : stratégies de dialogue et de présentation multimodales

Abstract : This thesis focuses on multimodal human-computer communication for public service systems. In this context, the naturalness of the communication relies on sensory-motor, cognitive and rhetorical accessibility of the interactive system by the user. Towards this goal of natural communication, we identify the key role of dialogic and presentation strategies : 1) A dialogic strategy of a cooperative information system defines the behavior of the system and the content to convey : Examples include relaxation, statement and restriction. 2) A presentation strategy defines a multimodal presentation specification, specifying the allocated modalities and how these modalities are combined. Highlighting the intertwined relation of content and presentation, we identify a new software component, namely the dialogic strategy component, as a mediator between the dialogue controller and the concrete presentation components within the reference Arch software architecture. The content selection and the presentation allocation managed by the dialogic strategy component are based on various constraints including the inherent characteristics of modalities, the availability of modalities as well as explicit choices or preferences of the user. In addition to the software development of this new component in two systems, we developed a design tool, which allows ergonomists and non-programmers to define and configure the dialogic strategies and to generate the dialogic strategy component of a particular system, as part of an iterative user-centered design process. Moreover this tool is integrated with a simulation framework for wizard of Oz experiments.
