	  abstract     = {The study explored varied types of human smiles and
extracted most of the key factors affecting the smiles. These key
factors then were converted into a set of control points which could
serve to satisfy the needs for creation of facial expression for 3D
animators and be further applied to the face simulation for robots in the
future. First, hundreds of human smile pictures were collected and
analyzed to identify the key factors for face expression. Then, the
factors were converted into a set of control points and sizing
parameters calculated proportionally. Finally, two different faces
were constructed for validating the parameters via the process of
simulating smiles of the same type as the original one.},
