As a means of getting over the linguistic barrier between different languages, a sign-language communication system using CG animation techniques has been studied. In order to generate a kind of sign-language animation in the system, the joint angles of the arms and the hands corresponding to the gesture have to be determined Up to date, however, the values of joint angles have been decided by trial-and-error methods based on the animator's experiences To overcome the drawback, m this paper, we design an integrated keyframe editor of the arms and the hands for 3D sign-language animation with which we can easily and quickly generate the keyframes of the sign-language animation required to build up In the Implemented keyframe editor, the values of joint angles are calculated by using mverse kinematics, and the same transformation matrix is applied to the joints of two arms and twenty fingers Experimental results show a possibility that the editor could be used efficiently for making up the sign-language communication dictionaries needed for inter-communication between different languages
