本研究初探VR中可能身體的感知(Perception of Possible Body)，如何藉由電影中透視拍攝的概念，探索微縮世界的邊界與生活世界的邊界比例關係，反思在外部空間的結構變化下各種身體感知存在的可能性。實驗設計了4種場景與7組高度變化，將insta360所拍攝的空間素材透過VR進行身體感知體驗。以文字與圖像紀錄受試者當下陳述，再依據受試者陳述的內容進行身體模式分析，包含只改變身體意象(Body Image)、只改變身體圖式(Body Schema)、身體意象與身體圖式同時改變與身體不改變的四種身體模式進行編碼。研究反思若只以視覺作為身體感知的途徑，將能以身體裡存在的最小偏離原則進行身體感知的解釋。VR已被視為一種敘事文本世界的新體裁，進入文本世界已非仰賴平面閱讀與想像，VR作為重新理解文本世界的方式。在此，本研究貢獻可能世界的敘事理論——最小偏離原則(The minimal departure)轉向VR最小偏離原則，作為初步VR敘事中可能身體感知的理論探勘。

This study investigate how the perception of Possible Body in VR. Explores the relationship between the boundaries of the miniature world and the boundaries of the living world through the concept of perspective filming in film, and reflects on the possibility of various body perceptions in the context of structural changes in external space. The experiment was designed with four scenes and seven sets of height variations, and the spatial footage captured by insta360 was experienced through VR for bodily perception. Text and images were used to record participants' statements, and body schema analysis was conducted based on the participants' statements. Four body schemas were coded: Body Image only, Body Schema only, Body Image and Body Schema at the same time, and no body change. VR has been seen as a new genre of narrating textual worlds, where access to textual worlds no longer relies on flat reading and imagination, but VR as a way to re-understand textual worlds. Here, this study contributes to the minimal departure principle, a narrative theory of possible worlds, by turning to the principle of minimal departure in VR as a preliminary theoretical investigation of possible bodily perception in VR narratives.
