Abstract

本稿では、人間が自然な表情した場合 : 自発表出と典型的な表情を演じる際の顔表情 : 演技表出を撮影し、顔の各部位に設定した特徴点の変位量に基づき顔の動きの定量的な測定を高速度カメラを用いて分析した。また測定結果からCGによって構築した顔モデルのアニメーション生成を行った。自発表出条件、演技表出条件ともに顔の各部位の動き出しの差は微細であり高速度カメラを用いたことの有効性が示された。また情動ごとおよび表出条件ごとに顔の動き量や速さに特徴的な違いが認められたが、動きの変化そのものの様相には興味深い共通性が認められた。顔モデルのアニメーションに関しても、線形補間によるキーフレームアニメーションと比べより自然な顔表情表出が可能となった。

The present study investigated the dynamic aspects of facial movements in spontaneously elicited and posed facial expressions of emotion. We also simulated facial sunthesis by using results from an analysis, the animations that we produced confirmed differences in the intensity of the facial expressiveness. We recorded participants' facial movements when they were shown a set of emotional eliciting films, and when they posed typical facial expressions. We measured facial movements frame by frame in terms of displacements of facial feature points. Such micro-temporal analysis showed that, although it was very subtle, there exits the characteristic onset asynchrony of each part's movement. Furthermore, it was found the commonality of each part's movement in temporal change although the speed and the amount of each movement varied along with expressional conditions and emotions.
