A Concept Design for a Positive Mood Supporting Application

Mood and emotion are considered distinct phenomena, yet there is a general lack of consensus within the scientific community concerning their definition. Leveraging on a physiology-based definition of these phenomena and their relation, we propose a concept design to define a real-time realworld positive mood supporting application. In particular, the application will be provided through wearable and portable devices, and comprise different blocks related to the user profiling, the identification of proper mood stimuli based on the users' responses, and a mood detection system. Therefore, multiple data will be exploited to provide an effective and efficient positive mood support, starting from user demographics, moving to an ecological momentary assessment of mood, and integrating physiological signal analyses.
