Abstract
A novel three-dimensional human motion synthesis based onjoints editing is proposed. Editing existing joint-trajectoriesto synthesize a new motion is a well-known 2D motion synthesismethod. In this study, we extend this notion to threedimensionalhuman motion synthesis and a prototype motionsynthesis system is implemented. By editing the projectedtrajectories of major joints through the user-interface, thesystem can synthesize the expected three-dimensional humanmotions automatically.Moreover, functions for synthesizing exaggerated 3D humanmotions are also studied and incorporated into the system toimprove its descriptive power. Finally, several empiricalexamples are given to demonstrate the effectiveness of theproposed approach.
