L’expérience utilisateur : Relations entre utilisabilité et esthétique, affects et comportements dans une tâche de recherche d’information sur tablettes numériques

While the study of human-machine interactions is fairly well established regarding usability dimensions, the approach of the user experience, more recent, incorporates new dimensions in order to bring to light on these interactions. This work takes part in this approach and aims to clarify the relationship between a non-functional quality and a functional quality of a system, the main effect of these qualities on the affects experienced during the interaction with the system and finally the effect of the system qualities on behaviours. A research information task on 4 Websites corresponding to both crossed variables, aesthetics (high vs low) and usability (high vs low), should allow us to explore these questions through self-reports measures and behavioural recording. In addition, we attempt to identify relevant indicators which have not been used much yet. This study is run on touch tablet computers on Windows systems.
