The development of computer technology has created artifacts that have more complex and intelligent functions. Such artifacts need more sophisticated interfaces than primitive artifacts. In this paper, we discuss which characteristics are appropriate for interfaces with artifacts and propose a concept of active affordance. We describe an autonomous mobile chair that we built as a test bed for active affordance. We also describe a experiment that we performed with a real robot that show the validity of our proposed method.
