Sending 3D motions, receiver's terminal can produce signing avatar to increase readability of signs. This system consists of following components as shown in Fig. Sender obtains signs as geometric data and sends it. Motion measuring part measures hands, arms and upper body motions. Encoder encodes and compresses obtained data.
Receiver receives kinematic data of signs and displays avatar.
Decoder decodes given data into kinematic data. Avatar producing part produces avatar from given kinematic data and display it. This part makes use of reader's viewpoint information if needed. Produced avatar can be virtual CG avatar, robot, etc. SenderReceiver Figure 1.
