    Abstract: 近年來由於電腦軟硬體及人機介面介面技術的發展，互動數位敘事(Interactive Digital Storytelling, IDS)的應用也逐漸被重視，特別是在新型態電腦遊戲的設計，而這個趨勢也為即時虛擬攝影機的規劃帶來新的機會與挑戰。本研究旨在透過互動數位敘事腳本內容的分析，建置客製化攝影機運鏡實驗平台，即時自動產生符合情境情節、人物情緒的拍攝方式，並參考電影拍攝手法，結合攝影學的專業知識加入不同拍攝風格，讓同一段影片可以有不同的風格效果。我們希望能夠讓現有的互動敘事系統The Theater [1]中的運鏡技術有跡可循，不再只是以人工的方式憑藉直覺來設定攝影機的位置，而能使得虛擬攝影機的操控變得簡易，修正拍攝效果時將更加簡便，成功快速掌握運鏡的每一個細節。我們在The Theater的實驗平台之上，讓敘事者可以根據故事情境客製化虛擬攝影機的拍攝手法，並由電腦自動產生合宜的攝影機拍攝位置，快速完成攝影機規劃。我們以實例透過實驗的方式驗證此系統的有效性。
    The recent advances in computing technologies and human-computer interactions have attracted much attention in the development of interactive digital storytelling (IDS), especially in the application of novel computer game design. This trend does not only bring new opportunities but also new technological challenges to virtual camera planning. Our research in this work aims at building an experimental platform for customized virtual camera planning through the analysis of screen play in an in-teractive story. By adopting the domain knowledge of camera controls in existing films, we hope to design a computer-assisted system that allows an author to easily experiment with different styles of virtual cameras in a same story. We proposed to design an experimental platform based on “The Theater” IDS, which currently uses a pre-authored way to specify the camera position. In the proposed system, we allow an author to quickly customize virtual camera taking according to the context of a story fragment and let the computer generate appropriate camera configurations automati-cally. We use an example story to verify the effectiveness of the system through ex-periments.
