This is because all the virtual balls need to be synchronized with the motion of the character temporally and spatially as following the laws of physics. Moreover, a skillful actor is needed for capturing the motion. We introduce a simple but interesting method such that anyone can synthesize an animation of skillful ball-handling motion using interaction patterns without any actual ball. Interaction patterns involve regularly repeated human motions to control the virtual ball. We first capture the motion that mimics controlling a ball using various interaction patterns. Then we synthesize the trajectory of a virtual ball by analyzing the captured motion and correct the character motion to be fitted to the synthesized trajectory of a virtual ball. Experiments convincingly show the usefulness of proposed technique by synthesizing various ball-handling animations.
