空间计算驱动下扩展现实(XR)沉浸式叙事的技术重构与实现路径OA

This paper investigates XR immersive storytelling within the context of spatial computing,analyzing its technical mechanisms,diverse forms,and engineering pathways.Focusing on the Venice Immersive program at the 82nd Venice In-ternational Film Festival and drawing on technical analysis,case studies,and media theory,the study explores the roles of technologies such as simultaneous localization and mapping(SLAM),six degrees of freedom(6DoF),3D Gaussian Splat-ting(3DGS),eye tracking,gesture recognition,and physiological feedback in spatial generation,viewpoint organization,and interaction orchestration.The research reveals that the evolution of XR immersive works is not merely a linear en-hancement of immersion,but rather a simultaneous reconfiguration of viewing positions,narrative spaces,interactive inter-faces,and the boundaries of the work itself.Specifically,Face Jumping,Alien Perspective,and Best of Worlds exemplify three distinct pathways:gaze-triggered interaction,the spatialization of digital heritage,and platform-based virtual worlds.The findings suggest that XR immersive storytelling requires integrating low-latency rendering,spatial scripting,attention steering,platform compatibility,and digital preservation into a unified production system,thereby advancing the medium from a showcase of cutting-edge technology toward a form of cinema capable of sustainable evolution.
