A Study on an expression pattern of character through the muscle movement

다국어 초록 (Multilingual Abstract)

We could see the fact that the muscles that have the most influence on facial expression were forehead muscle, occipital muscle and cheekbone muscle. Various expressions have been produced according to relaxation of these muscles, degree of contraction and the directions of exercise.
While the entire face muscle becomes relaxed for being cheerful, happy, comfortable and surprised showing positive facial expressions, it became relaxed as the cheekbone muscle at both ends of the mouth and forehead muscles performed the upward motion. In other words, various positive facial expressions have been expressed depending on the degree of upward motion at both ends of the mouth and size of mouth opening.
While there was a similarity of entire face muscle becoming contracted for being angry, sad, depressed and weary that are negative facial expressions, the downward motion of forehead muscles around the eye and cheekbone muscles around the mouth going down has been shown.
While 2D characters and 3D characters showed a delicate shade of difference in their method of expression, the 2D character which has excessive distortion and exaggeration for the most part has shown some difference from realistic based 3D Character in that its expression exaggerates and overstates the actual muscle movement of a human being.
