目的 旨在以XR体验为背景进行跨现实交互与协同感知研究综述，分析并提出增强观众体验的方法与设计建议。方法 采用文献综述与案例分析方法，重点分析了XR空间的弥合与跨越、沉浸式媒介下的观众行为交互与情绪感知，提出相关交互框架与设计原型并应用于具体案例。结果 XR技术显著增强了观众与虚拟环境的互动体验，同时生物反馈技术的融入为观众情绪的协同感知提供了新的手段。结论 跨现实交互与多人情绪感知反馈在沉浸式体验中的应用前景广阔，但仍需持续优化交互设计、提升观众体验，以促进沉浸式媒介体验的社会性可持续发展，从而推动数字创意产业的革新。

The work aims to review the research on cross-reality interaction and synergetic perception in the context of XR experience, and to analyze and propose methods and design suggestions to enhance audience experience. Based on literature review and case study methodology, the bridging and crossing of XR space, audience interaction and emotional perception in immersive media were mainly analyzed, and relevant interaction frameworks and design prototypes for application in specific cases were proposed. The results showed that XR technology significantly enhanced the interaction experience between the audience and the virtual environment, while the integration of biofeedback technology provided a new means for the collaborative perception of the audience's emotions. Cross-reality interaction and multi-person emotion perception feedback in immersive experiences is promising, but it is still necessary to continuously optimize the interaction design and enhance the audience experience, so as to promote the social sustainable development of immersive media experiences, and thus to promote the innovation of the digital creative industry.
