We introduce the overall paradigm for our multimodal system that aims at recognizing its users emotions and at responding to them accordingly depending upon the current context or application. We then describe the design of the emotion elicitation experiment we conducted by collecting via wearable computers physiological signals from the autonomic nervous system galvanic skin response heart rate temperature and mapping them to certain emotions sadness anger fear surprise frustration and amusement . We show the results of three different supervised learning algorithms that categorize these collected signals in terms of emotions and generalize their learning to recognize emotions from new collections of signals. We finally discuss possible broader impact and potential applications of emotion recognition for multimodal intelligent systems. Keywords and phrases multimodal human-computer interaction emotion recognition multimodal affective user interfaces. 1. INTRODUCTION The field of human-computer interaction HCI has recently witnessed an explosion of adaptive and customizable human-computer interfaces which use cognitive user modeling for example to extract and represent a student s knowledge skills and goals to help users find information in hypermedia applications or to tailor information presentation to the user.
