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.
