以數位人體模型進行產品初期的評估與應用越來越多，利用動作擷取系統產生逼真的人體動作與利用快速自動化的動作產生機制一直是數位人體模型動作產生的取捨議題。本研究著重作業導向的數位人體動作呈現，以現有工作站模擬與新工作站模擬作為系統應用範圍，盼建立快速、直覺與真實的動作產生機制，產生作業動作的模擬以作為工作站設計與評估之用。

本研究在3ds max動畫平台下，以Qualisys動作擷取系統為動作資料的來源之ㄧ，藉由本研究開發的數位人體模型可以完整、視覺化地呈現動作模擬；進一步開發動作編輯工具讓使用者可以基於不同目的和設計變更，將原始動作資料加以編輯、修改與儲存，使原本難以再利用的動作資料可以提升整體使用效率，達到相似動作的快速產生，且讓整體動作模擬更為真實。
另外，本研究建立在上述工具的開發基礎下，另開發以MTM為作業導向之動作產生的語意標準，讓使用者可以直接以MTM語意和作業環境資訊的輸入，即可快速、合理與自動化地產生作業導向的數位人體模型動作，包含上肢任務作業的模擬、下肢移動與轉向和全身性的姿勢修正。
「作業導向之數位人體動作產生」在3ds max環境下以maxscript程式撰寫介面，並自行開發能直接讀取動作擷取資料的數位人體模型，對於使用者能以最少的資訊與經驗即可快速模擬作業導向的動作，並可透過動作編輯等工具進行動作的修改以符合更多設計變更後的動作模擬，本研究產出的數位人體動作模擬資料具有空間與時間資訊，可以進行人因分析、動作研究、工作站設計、系統模擬等延伸應用與分析。

The evaluations and applications of using digital human model on the early stage of product design have played an important role. How to simulate a realistic human motion and automate the processes by simple steps are always the key issue in this topic. This study focused on the generations of operational motions by digital human model. The results of operational simulation can be useful for locomotion analysis, time analysis, and posture analysis.

The study builds a new digital human model on 3ds max software, using motion capture system (Qualisys) as one of motion data sources. The use of digital human model can visualize and present the realistic motion completely. Also, the users can modify and reuse the original motion data to fit new operational changes by motion editing tools. The methodology can enhance the efficiency of motion data use and improve the presentation of detailed motion simulation.

In addition, the study used MTM as the basis for semantic motion definition. Users can input MTM motion sequences and CAD objects to produce the operational simulation quickly and intuitively. The method of using MTM as motion command can produce the upper limbs motion, lower limbs movement, and posture modification. The module was built for new work station without physical mockups and real subject information.

Further, a user interface was constructed by maxscript, and a digital human model that can receive motion capture data or be controlled by MTM semantic commands. Users can spend less effort to generate operational simulation in an independent system. They also can modify and reuse an original motion data for a similar task. The main results of operational simulation can be extended to locomotion analysis, time analysis, and ergonomic evaluation.
