Detecting Thermal Emotional Profile

Yang Fu, Claude Frasson


Human can react emotionally to specific situations provoking some physiological changes that can be detected using a variety of devices, facial expression, electrodermal activity, and EEG systems are among the efficient devices which can assess the emotional reactions. However, emotions can trigger some small changes in blood flow with an impact on skin temperature. In the present research we use EEG and a thermal camera to determine the emotional profile of a user submitted to a set of emotional pictures. Six experiments were performed to study the thermal reactions to emotions, and in each experiment, 80 selected standard stimuli pictures of 20 various emotional profiles from IAPS (a database of emotional images) were displayed to participants every three seconds. An infrared camera and EEG were used to capture both thermal pictures of participants and their electrical brain activities. We used several area of the face to train a classifier for emotion recognition using Machine Learning models. Results indicate that some specific areas are more significant than others to show a change in temperature. These changes are also slower than with the EEG signal. Two methods were used to train the HMM, one is training classifier per the participant self data (participant-independent), another is training classifier based on all participants` thermal data (participant-dependent). The result showed the later method brings more accuracy emotion recognition.
