In the paper we present two novel interactive tools, Emotion Disc and Emotion Squares, to explore the facial expression space. They map navigation in a two-dimensional circle, by the first tool, or in two two-dimensional squares, by the second tool, to the high-dimensional parameter space of facial expressions, by using a small number of predefined reference expressions. They can be used as exploration tools by researchers, or as control devices by end-users to put expressions on the face of embodied agents or avatars in applications like games, telepresence and education.
