Telecommunication Using 3DCG Avatars Manipulated with Finger Plays and Hand Shadow

The authors propose a manipulation method of 3D avatars in telecommunication. The idea of the method came from finger plays and hand shadow. The avatar animates synchronously with the user’s finger play or hand shadow. The users can manipulate their avatars with the hands easily and intuitively. The authors implemented a telecommunication system and carried out an experiment. The participants were able to communicate with manipulating their avatar well. They felt the communication using the system comfortable and familiar.
