Domestiquer l’information énergétique : Confronter les choix de conception de dispositifs de feedback et les pratiques des usagers pour proposer une démarche de design

Abstract : Feedback systems have been produced over the past 20 years with the goal of engaging users to consume less electricity. However, many studies point out their limitations in the domestic context.In this thesis, we argue that taking into account the actual practices of users could generate new leads on energy feedback devices.We create a Design Space to describe the designers' point of view. We analyze their choices, such as the data used, the ways to represent and disseminate it, as well as the tasks assigned to the users.As a counterpoint, we conduct an empirical study with 10 participants. Through interviews and in situ observations, we describe and analyse how they perceive electricity, estimate their consumption and adopt strategies for accessing energy information.Important differences between these two points of view are identified. We use these findings to propose perspectives for future designs.The second part of this thesis explores one of these perspectives. At the crossroads of industrial and academic challenges, the definition of a device, called "Interstices Informationnels", is proposed.To explore this concept, we design a creative workshop where 15 proposals are generated by a group of design students. The "Interstices Informationnels" will be reworked with the designers of the EDF Design Lab. Four demonstrators are created and patented.
