近年來互動數位敘事(Interactive Digital Storytelling, IDS)的發展日漸被重視，有部分研究針對互動數位敘事開發故事腳本編輯工具，雖然這些編輯工具考慮了沒有互動數位敘事腳本編劇經驗的作者，但仍缺乏創作豐富度、工具易用性及共同創作功能。本研究目標為建立互動數位敘事之智慧型共同創作平台( Intelligent Collaborative Authoring Platform, iCAP )，透過將故事元素視覺化，故事內容設定參數化等，加上智慧型檢驗運算，讓故事編劇們能夠透過此平台編修互動故事腳本，並在舞台環境中呈現新的故事內容。我們以現有的互動數位敘事系統The Theater[1]為舞台呈現，透過iCAP整合其故事腳本及環境建置設定。我們建立了簡單易懂的操作介面、規劃故事腳本可修改範圍的限制、將故事動畫腳本設定參數化、建立的故事腳本的共同創作機制以及輔助創作的智慧型提示與結果運算，並設計一系列的任務式實驗以及評估問卷來評估系統，透過實驗結果驗證了本研究的智慧型共同創作平台的價值，能讓不同的腳本編劇在此平台上方便、快速的工作，而使得互動數位敘事之腳本編輯變得較簡易，修正演出效果時將更加有效率，故事內容也更豐富。 / Interactive Digital Storytelling (IDS) has become more popular these days. Some of the pre-vious researches about IDS have considered the design of story editor. Although they have designed the authoring tools for authors who may not have the editing experience of IDS sto-ries, they usually lack the features of enabling rich contents, easy-to-use, and collaboration among multiple users for IDS story editing. Our system, named iCAP, is an Intelligent Col-laborative Authoring Platform for IDS, using "The Theater" as the IDS animation platform. The iCAP system contains a graphical user interface for making the story editing process eas-ier and the storyline more readable. The iCAP system includes the collaborative features such as the settings of access rights, the parameterization of the scenario settings, the authoring logs of the collaborative process, and the intelligent error detecting tool that is used to detect the errors occurring in a story structure. We have conducted an experiment to verify the usa-bility and the collaborative features of iCAP. In addition, we have obtained feedbacks from the users about the advantages and disadvantages of iCAP and verified the value of the plat-form for IDS.
