Abstract :
The paper mentions that although direct manipulation for figure animation has long been possible using inverse kinematics, there has been no similar "inverse kinematics" approach for blendshape models. In both problems the system must infer unknown degrees of freedom during each edit. We solve this problem by minimizing changes in facial expression.
