In this paper, we propose a new method to concatenate two dynamic full-body motions such as punches, kicks, and flips by using the angular momentum as a cue. Through the observation of real humans, we have identified two patterns of angular momentum that make the transition of such motions efficient. Based on these observations, we propose a new method to concatenate two full-body motions in a natural manner. Our method is useful for applications where dynamic, full-body motions are required, such as 3D computer games and animations. Copyright © 2009 John Wiley & Sons, Ltd.
