    Abstract: 3D 虛擬環境中互動敘事的設計是近年來具潛力的數位內容發展形式。互動敘事的目 的是在讓使用者能透過系統所提供的即時互動方式，參與故事的發展，進而影響故事的體 驗與結局。使用者參與故事發展可以提高敘事的趣味性，但如何確保互動過程的合理性及 內容產生的適切性，是亟具挑戰的研究議題。本計畫提議以兩年的時間，進行 3D 虛擬環 境中互動敘事相關核心技術的研究，以數位虛擬動畫演員相關技術為基礎，分析 3D 虛擬 環境平台於互動敘事上的特性，嘗試產生客製化的 3D 內容，提供使用者新的互動敘事體 驗。第一年計畫已獲通過並執行中，本計畫為兩年期的第二年。在第一年的計畫裡，我們 的研發重點在發展新的數位演員動畫產生技術，例如以運動計畫街圖法強化動作圖(Motion Graph)的連接性、以多層式動作圖方式增進運動擷取資料的重用性、以語意標記加速動作 搜尋效率等。另外，我們也將進行互動敘事趣味性與複雜度的探討，以定義一個互動敘事 劇本的適合性。在第二年的研究裡，我們將以敘事理論為基礎，設計一個多層次的互動敘 事系統架構，提供互動敘事者以物件導向方式設計內容，系統便能自動根據使用者偏好及 應用情境產生互動劇本，並整合第一年研究成果自動產生適合的角色動畫及拍攝方式。我 們相信本計畫預期的研究成果，能提升數位內容產業中 3D 即時動畫及數位敘事的技術， 並提供創新的設計發展方向。
    Interactive storytelling in 3D virtual environment is one of the most promising applications of 3D contents in recent years. The goal of interactive storytelling is to allow a user to par- ticipate in telling a story and determining the plot and result of the story. Although allowing user participation can potentially enhance the richness and enjoyment of narratives, it is also a challenging issue to ensure appropriateness of story contents and good user experience during the interaction. We have proposed to use two years to develop related technologies for realizing this kind of 3D interactive narrative system. In the undergoing first-year project, we focus on developing new real-time techniques for the generation of animations for digital actors. We are developing a hierarchical motion graph for human bodies to synthesize mo- tions by reusing partial motions in the hierarchy such that character motions can be smoothly generated on demand. We are also investigating how to use virtual cinematography to con- trol camera automatically according to the requirement of dynamic story scenario. In addi- tion, we are also studying the complexity and enjoyment of interactive narratives from the literature in order to derive a good definition of these indices. In the second year, we propose to design a hierarchical system architecture for interactive storytelling in a 3D virtual envi- ronment. This system shall allow an interactive script writer to design a set of stories with an object-oriented approach and generate a good interactive story plot in real time according to user preferences and application requirements. The modules developed in the first year will also be incorporated in this integrated system. We believe that the expected result of this re- search will shed some lights to a novel design direction for 3D entertainment.
