Over the last decade, technological and Internet innovations have increasingly invaded the consumer market (N’Goala, 2016). The Internet of Things (IoT) is becoming a common platform, and disrupts relationships between consumers and companies (Bohli et al., 2009); in essence, this is a timely research. The major goal of this thesis is to deepen the understanding of the acceptance and the adoption processes of the IoT and smart connected technologies, as well as the related consequences on perceived well-being. To do this, four contexts of study have been explored: smart connected objects, smart sleep applications, smart homes, and smart stores. First, we performed qualitative exploratory studies, and secondly we conducted quantitative studies to build conceptual models according to our qualitative findings and the literature. The results show that technology benefits are the first factors that enable technology acceptance through perceived usefulness and perceived ease of use; subsequently, self-improvement, through perceived social image and well-being benefits, are the main reasons to continue using the IoT and smart connected technologies. The acceptance and the adoption of these technologies also depend on users’ personality traits while perceived risks and fears on the use of the personal data are the main barriers. In turn, the IoT and smart connected technologies influence perceived well-being according to the experience of use, personality traits, and the technology.Le résumé en français n'a pas été communiqué par l'auteur
