From Keyframing to Motion Capture

A survey is given for human motion synthesis techniques from the viewpoint of human computer interaction. The focus is on an overview based on the interaction of animation systems between human and computer. To design a good interactive system, we concern the underlying structure of such a system more than the concrete interface that the system will adopt. Therefore, we first analyze the tasks of animators for designing a human motion synthesis system. After reviewing the evolution of human motion synthesis, we try to reveal how such evolution improves interaction between human and computer. Finally, we demonstrate our motion synthesis system and give some suggestions for future research directions.
