The human hand is used to express characters by its posure. Pygmy is an anthropomorphic device that magnifies the finger expressions. It is based on the concept of hand anthropomorphism and uses finger movements to create the anthropomorphic effect. Wearing the device is similar to having eyes and a mouth on the hand; the wearer's hand spontaneously expresses a presence of living thing with the emotions conveyed by the eyes and mouth. Interactive manipulation by controllers and sensors make the hand look animated. We developed small parts of robotic eye and mouth with electromagnetic motor. We observed that the character animated with the device provided user collaboration and interaction as though there were a living thing on the user's hand.
