Behavioral Expression Design onto Manufactured Figures

Abstract

Natural language user interfaces, such as Apple Siri and Google Voice Search have been embedded in consumer devices; however, speaking to objects can feel awkward. Use of these interfaces should feel natural, like speaking to a real listener. This paper proposes a method for manufactured objects such as anime figures to exhibit highly realistic behavioral expressions to improve speech interaction between a user and an object. Using a projection mapping technique, an anime figure provides back-channel feedback to a user by appearing to nod or shake its head.
