Demo Abstract: MoodMagician- A Pervasive and Unobtrusive Emotion Sensing System using Mobile Phones for Improving Human Mental Health

In this demo, we present MoodMagician, a pervasive and unobtrusive mobile phone system for inferring human emo-tions through the recording, processing, and analysis of the real-time streaming Galvanic Skin Response (GSR) signal from human bodies. Being different from traditional mul-timodal emotion sensing systems which rely on data from multiple sensing sources and may hence interfere with peo-ple’s daily life, our proposed system is able to detect vari-ous categories of human emotions using single GSR signal, which is captured by compact and wearable mobile sens-ing devices in an unobtrusive fashion. The proposed system has been evaluated by well-designed practical experiments to recognize human emotions. The recognition accuracy of each emotion can be up to 70 % through the development of effective preprocessing algorithms and the extraction of rep-resentative features from the GSR signals.
