Étude de l'effet de synchronie pour la conception d'IHM adaptatives : Effet sur la vigilance, la charge mentale, la conscience de la situation et les performances

Abstract : The field of Human-Machine Interaction (HMI) has been interested in interindividual differences and its effect on performance since the beginning. To address the challenges posed by these variabilities in the design process, 3 types of HMI have been categorized:User-adapted HMIs, adaptable HMIs, and adaptive HMIs taking into account the current user’s characteristics. The implementation of this last category needs the support of several disciplines in order to determine the factors to take into consideration in relation to the current task and activity and products user models of the operator’s state so as to adjust the HMI accordingly. In this thesis, we were interested in interindividual and intraindividual variabilities via the study of synchrony effects (optimal or suboptimal time of day according to the considered individual’s chronotype (morning type/intermediary type/evening type)) and the level of alertness on performances. The synchrony effects have been studied in other fields such as marketing but are very under-studied in the HMI field. An experiment has been conducted with 62 participants in order to study the effect of time-of-day, chronotype and task difficulty on performances during a navigational simulation task. The results show significative effect of these factors on performance and operator’s functional state with different sensibilities depending on the indicator used, which allows possible recommendations on the consideration of those factors in adaptive HMI design.
