Immersive video, namely 180-degree and 360-degree video designed to be viewed through head-mounted displays, constitutes a boundary case between interactive VR and conventional two-dimensional video for reconsidering self-experience in XR. It can generate a sense of being there without providing a corresponding body, while allowing only limited sensorimotor contingency through head rotation. From a phenomenological standpoint, this paper reinterprets presence in immersive video not as bodily extension or ownership of an avatar, but as a form of self-experience in which self-location becomes relatively dominant under conditions of reduced body schema availability. This paper calls this condition a self-location-dominant state. In immersive video, the user cannot actively intervene in the recorded environment, and stable agency or ownership is difficult to establish. Nevertheless, events such as viewpoint motion, impact, and direct address are not experienced merely as changes within an image, but as events concerning the position of the self. The minimal self in immersive video is therefore redescribed not primarily as a subject of agency or ownership, but as a self spatially located at a viewpoint while the body schema remains backgrounded. This perspective connects research on presence, the sense of embodiment, and the minimal self, and proposes self-location as a central analytic axis for theorising self-experience in immersive video.

翻译：沉浸式视频（即设计用于头戴式显示器观看的180度和360度视频）构成了交互式虚拟现实与传统二维视频之间的边界案例，为重新思考扩展现实中的自我体验提供了可能。它能够在不提供相应身体的情况下产生在场感，同时仅通过头部旋转允许有限的传感器运动偶发性。从现象学视角出发，本文重新诠释了沉浸式视频中的在场，不将其视为身体延伸或化身所有权，而是作为一种自我体验形式，其中在身体图式可用性降低的条件下，自我定位变得相对主导。本文将这种状态称为"自我定位主导状态"。在沉浸式视频中，用户无法主动干预录制环境，稳定的施动性或所有权也难以建立。然而，视点运动、冲击和直接注视等事件并非仅作为图像内的变化被体验，而是作为关乎自我定位的事件被感知。因此，沉浸式视频中的最小自我被重新描述，不再主要作为施动性或所有权的主体，而是在身体图式保持背景化的情况下，作为一个空间定位于视点的自我。这一视角连接了在场感、具身感与最小自我的研究，并将自我定位作为理论化沉浸式视频中自我体验的核心分析轴线。
