VR作為一種新的敘事媒體，其特有的沉浸感可以讓觀者走進故事的世界「體驗」故事的發生，而不僅僅在「看」故事角色的演出。也因為其無景框及觀者主動參與的特性，許多導演紛紛嘗試並摸索全新的VR媒體敘事方式。本研究透過分析現有之VR敘事影片，從中歸納VR之特有敘事創作技巧與傳統影像敘事技巧在VR中的使用情形。並以此製作出VR短篇敘事動畫「女子」與搭配使用之觸覺回饋裝置，內容講述一名少年對自身性別認同的探索與他所面臨家庭與社會帶來的困境，敘事手法嘗試運用VR的優勢，巧妙利用360的空間安排劇情、讓觀眾與劇情互動以強調故事劇情以及核心價值觀，透過適當的引導讓觀眾在保有完整觀看自由度下也不會錯過導演精心安排的劇情畫面，並利用角色扮演及觸覺回饋裝置加強觀眾的沉浸感與對角色的同理。本作在最後依照分析的敘事技巧重新檢視其在VR動畫「女子」中的應用情形，並討論了實際製作時所遇到的問題，以提供給未來想以VR說故事的導演參考並運用。

Virtual reality as a new medium allows viewers to immerse into a virtual world, letting them directly "experience" a story instead of only "watching" a performance of characters. Unlike traditional 2D films with frames, viewers can freely explore a virtual world and actively participate in VR stories. These unique features have become the main challenge for directors, and many directors start exploring new storytelling methods in VR. This paper investigated VR storytelling methods and classified the unique storytelling techniques, including the traditional film techniques used in VR. Based on these techniques, we created a VR animation "She" and a tailored haptic wearing device. The story is about a boy facing gender identity and the challenges of his family and society. To enhance the experience of the core concept, we let viewers become part of the story and interact with it. Viewers have the freedom to explore the scenes, but in the meanwhile, they will be guided appropriately through the story without getting lost. In addition, we include haptic feedback to enhance the viewers' immersion and allow viewers to empathize with the character. Finally, we examined the storytelling techniques in VR animation "She" and discussed the problems encountered during the development. The paper will benefit VR directors who try to use VR as a medium to tell stories.
