Abstract: Recently some studies have shown that the major influential factor of our health is not only physical activities, but the states of our emotion that we experience through our daily life, which continuously build our behavior and affect our physical health significantly. Therefore, emotion recognition draws more and more attention for many researchers in recent years. In this paper, we propose a system that uses off the-shelf wearable sensors, including heart-rate, galvanic skin response, and body temperature sensors, to read physiological signals from the user and apply machine learning techniques to recognize emotional states of the user. These states are key steps, toward improving not only the physical health but also emotional intelligence in advance human-machine interaction. In this work, we consider three types of emotional states and conducted experiments on real-life scenarios, achieving highest recognition accuracy of 97.31%.
