Body motion editor for sign language avatar

Korean sign language is complex visual-spatial language most used in deaf society and is expressed by gestures using hands and other movements such as facial expression and body posture. In this paper, we present a body motion editor to control joint angles of whole body as well as facial expression of a sign avatar since deaf people express facial motion more often than hearing people to communicate easily with another signer. The body motion is represented by body motion symbols which construct a body motion database together with facial expression and complexion. The developed editor can help deaf people to communicate with hearing people using a sign avatar.
