臺灣博碩士論文加值系統

隨著虛擬實境等互動媒體裝置日益精進，互動數位敘事(Interactive Digital Storytelling, IDS)的發展也逐漸受到重視。但目前對於互動敘事的沉浸感較無整體性的研究，對於故事體驗者的互動裝置的輸入自由度也有較多限制，故事體驗者能改變的場景、故事，非玩家控制之動畫角色(Non-Player Character, NPC)反應等皆還有改進的空間。而這些限制，皆可能會影響故事體驗者對於互動敘事的沉浸感。本論文將探討在互動敘事中，不同層次的人物動畫產生方式、以及如何根據故事體驗者的體驗歷程而產生不同的故事發展。我們將使用虛擬實境及語音辨識等互動方式來增加故事體驗者的自由度，分析其在互動敘事中對沉浸感所造成之影響。我們透過一個範例故事，包含完整的敘事及動畫，在我們所設計的互動敘事系統中，根據使用者行為紀錄及問卷調查，評估本系統之設計對使用者體驗的影響。

With the development of interactive media devices such as virtual reality, Interactive Digital Storytelling (IDS) has become more popular these days. But there is not yet a holistic study on the immersion of interactive narratives, and there is also a limit on the degrees of free-dom that a user can use to experience interactive storytelling. In addition, there is still much room for further development such as scene and story variation, non-player character (NPC) responsive animation, etc. We think these factors all may affect the sense of immersion that a user experiences in interactive storytelling. In this thesis, we will focus on exploring two different aspects of these factors to analyze their impacts on immersion experience. The first aspect is to look into how the different levels of character animation and the progression of the interactive story can be used to create different animation responses for immersion enhancement. In the other aspect, we attempt to use Virtual Reality and other natural input devices in our storytelling to increase the degrees of freedom and naturalness of user input in experiencing the story. We have implemented such a VR-based interactive storytelling system with dynamic animation generation. We have also created an example to demonstrate and evaluate various features of the system. We will report and analyze the users’ feedbacks on the design through quantitative survey and behavior recording.
