An Emotion-Driven Interactive System

Emotion-based interactive music systems have great application potential, namely in entertainment and healthcare. This paper describes an installation that explores the interactive capabilities of EDME, an emotionbased music engine we are developing. At the core of the installation there is an affective computer system that selects appropriate music and images to express its emotional state. The installation allows people to experience and influence the emotional behavior of this system. We made two experiments where people were able to ascribe emotions to the system in a natural way, relating arousal with the amount of movement and valence with the number of presences, as expected. The system transmitted expected emotions and gains from using both media (music and images) to express its emotional state.
