This study focuses on the in-store experience in a smart retailing context, which is characterized by technological innovations. The in-store promotional and nutritional notifications are studied there, as well as their perception during a display and ultimately their effect on purchase intention, and on the feelings of brands intrusion via these notifications. In the field of Mobile In-Store Experience, more experiential data collection methods are called in the literature to deeply understand consumer behaviors. We choose a qualitative design with in-depth semidirective interviews including projective technics thanks to innovative dynamic and adaptative video. Our personalized video material simulates an immersive in-store shopping sequence. This methodology can reproduce conditions very close to reality to catch customer behavior. It seems to offer a new way to study the experience with a simple and inexpensive material. Moreover, our results highlight the importance of the choice process for customer, the relevance of message, and the perceived brand technology congruence.
