The research purpose is to study the impact’s use of connected devices on cardiovascular diseases. One of our objective is stress recognition during daily routine life. To achieve that a long term experimentation have been conducted. This longitudinal empirical research study aided by connected devices enabling psycho-physiological monitoring to study the correlation between emotional states including stress levels and prognosis of cardiovascular disease. In this paper, we will present the main participant’s feedback concerning the conducted experimentation using wearables sensors. This manuscript explains participant selection. It will not treat data conducted from this experiment or show numerical results. It is a statistical feedback concerning the experimentation protocol. We will clarify the protocol strengths and weaknesses. Our main motivation is to give an opinion to other research and to inspire them if they want to conduct a similar experimentation.
