Aide en ligne adaptative et assistants conversationnels animés : mise en oeuvre et évaluation ergonomique

Abstract : The goal of the thesis is to evaluate new forms of Human-Computer Interaction. More precisely, the general set of themes of this work, divided into two parts at aims implementing and evaluating the contribution of Embodied Conversational Agent (ECAs) and of adaptive interfaces for the use of software. Thus, behaviours and reactions of users are collected using ergonomic methods and eye-tracking technologies. An experimental approach was adopted in order to evaluate the contribution of each part. For that, participants (student of bachelor's degree) handled a software of animation's creation which was unknown for them (Flash) in order to carry out three scenarios. Throughout their exploration of the software, participants were accompanied by a help system. In the first experiment an ECA (provided by FT R & D) enunciate help messages; in the second one a adaptive system (detection of intention and evolution according to knowledge) was used. The various studies carried out show that the two innovations employed were perceived positively by the majority of the participants. They showed in addition that a ECA has a reassuring effect and that it can probably be used in first experiences with a software. For the adaptive system, the fact that the system evolves in an autonomous way did not disturb the participants, but hardly improves the performances.
