虛擬片場中錄製演員演戲之輔助系統

電影在現今社會中是許多人在選擇休閒娛樂活動時不可或缺的角色之一，其中，演員們精湛的演技更是人們欣賞的重點。然而，一般大眾若是想要嘗試體驗演戲的話，通常必須透過演戲的社團或者俱樂部，甚至戲劇班等才能有機會參與戲劇的創作。本研究的目的在於設計一套虛擬實境中的電腦輔助系統，在前人已經建立好的導演、攝影師、剪輯師體驗功能之基礎上，我們將建立演員的體驗功能，讓一般人能夠輕易地體驗演戲，並且一個人能創作屬於自己的虛擬電影。透過虛擬實境與運動捕捉裝置，我們的系統讓體驗者進入虛擬拍攝片場內，從選擇自己想要扮演的角色開始，到完成戲劇的演出與角色動畫的錄製，以及最後透過操作介面來檢視自己演出的成果。除了扮演單一角色之外，體驗者也能選擇演出與錄製多個角色，如此將能夠達成整部虛擬電影都是由體驗者一人完成的目的。體驗過程中，我們的系統能夠在每個階段適當的提示體驗者當下所應該做的任務。並且在體驗者演出時，利用Time Warping與Motion Warping等動畫編輯技術，來動態調整與體驗者對戲的電腦演員們之速度與動作。透過整體系統簡易的互動介面，體驗者能輕鬆地體驗演戲並產出屬於自己的演出內容。最後，我們透過一系列的實驗與使用者調查來探討系統的實用性，其中包括各種情況下的提示與輔助介面是否夠清楚且容易瞭解、以及系統的娛樂性是否符合體驗者的期待等等，以此來評估本系統是否達到設計的目標。

Today, movies play an indispensable role in entertainment for many people, and some people appreciate the superb acting skills of the actors. However, if people want to ex-perience acting, they usually have to go through acting clubs or drama classes to have the opportunity to participate in drama creation. Based on the existing functions of di-rectors, photographers, and editors in a virtual studio that have been established in pre-vious work, this research aims to design a computer-assisted systems in virtual reality with actor functions allowing people to easily experience acting and create their own virtual movie. Through virtual reality and motion capture devices, our system allows the user to enter the virtual studio as an actor. The user starts by choosing the character they want to play, and then completing the drama performance. The motion of the actor will be recorded and replayed with the animations of other characters for further inspection. In addition to playing a single role, the user can also choose to perform and record mul-tiple roles, such that the entire virtual movie can be completed by the user alone. Finally, we will evaluate whether the system has achieved the design goals through a series of experiments and user surveys.
