/ Résumé / The project presented in this paper is part of a broader research addressing in-between spaces and the designing of experiences taking place there. The project focuses on door frames, and inquires the way to improve social interactions taking place ‘at the door’. To do so, the approach is structured on an Experiential Design Landscape in order to create an in- between space with audio traces and to evaluate these traces impact on people’s behavior change. Our hypothesis is that sound traces triggers behavior changes. Evaluation is done quantitatively through the measurement of the door movements, and qualitatively based on laddering techniques mapped out in a mean-end chain. The results show no significant impact of the audio traces on people’s behavior change. However, emotional reactions could be observed. Although this first step revokes our hypothesis, it also has provided insight for further inquiry on in-between spaces.
