生動豐富的動作是角色動畫不可或缺的要素。近年來，為了讓使用者方便產生富饒變化的肢體動作，已有學者採用運動學，融合具上層語意的拉邦動作分析，以此做為動作變化控制的機制。
由於拉邦動作分析中的力道元件和動力質地變化有直接的關聯，因此本論文採用基於動力學之動作合成機制，模擬力道質地變化；並提出一種基於動力學之「動作捕捉資料驅動」的力道模擬器模型。此模型利用動作捕捉資料驅動的技術，因而能保有原始動作的細微逼真資訊。此外，模型採用動力學的理論基礎，因此力道的動力質地所展現之行為與動力學參數間的關聯性能夠用自然直覺的方式建構出來。同時，我們也建立了動力學參數和力道質地變化的關係表，有助於使用者能以具上層語意的力道質地參數做為調整依據，而後使用者指定的力道質地便能按照此關係表轉換成下層的動力學參數進行動作的合成。
本論文提出的力道模擬器不僅能夠有效地模擬原始動作範本，更能夠根據使用者下達的力道質地參數來變化動作範本之動作質地。最後，我們實際合成並討論不同力道質地產生的動畫結果，以此驗證我們所提出的方法。

Expressiveness is an essential ingredient of character animation. The Effort component of Laban Movement Analysis (LMA) has been studied for providing users with expressive motion control of articulated figures.
As the Effort component is directly related to the dynamic qualities of a movement, this thesis tries to explore the dynamic computation aspects of the Effort component. A dynamic-based and motion capture-driven computation model for motion simulator is proposed. Since it is motion capture-driven, it is able to retain realistic details of the given example. Moreover, since it is dynamic-based, the relationship between dynamic behaviors of the Effort qualities and dynamic parameters of low-level controller can be investigated in a more natural way. The correspondences between controller's parameters and Effort qualities are established so that the specified Effort quality can be realized by varying their corresponding dynamic parameters.

In other words, the proposed motion simulator not only can mimic the given example effectively, but also provides control capability for varying motion qualities according to specified Effort qualities. In order to demonstrate the effectiveness of the proposed simulator, several experimental examples are presented and their results are discussed.
