随着交互技术的发展，叙事学也逐渐与新的技术融合，探索出了交互式叙事学这一新的领域，并且该领域的研究方式不断创新，呈现出多元化的研究势头，为研究者们提供了丰富研究空间。交互式应用研究重点关注人机交互（HCI），探索用户行为会如何影响应用环境的变化。在交互式叙事的研究中，故事的受众是观众也是用户，所以探索空间中用户与故事之间的关系，是人机交互也是交互式叙事的研究范畴，并且用户与技术介入下的叙事形态必然会面临着升级。本文拟从交互式叙事的编排、用户与叙事空间的映射关系以及交互技术的输入与输出三个角度阐述叙事空间与实体空间融合能为交互式叙事带来的新形态。本研究以实体空间中的用户自然行为为切入点，探索如何利用用户的行为与故事产生合理交互关系，进一步总结设计实体空间中的交互式叙事影像装置的方法，并以实体影像交互装置为实践，阐述设计方法可用性。

With the development of interactive technologies, narratology has gradually merged with new technologies, explored a new area of interactive narratology, and the research methods in this field are continuously innovating, providing researchers with rich research space. Interactive application research focuses on human-computer interaction（HCI）.And explores how user behavior affects the application environment. In the interactive narrative, People have dual identities：audience and user. Exploring the relationship between user and story in the physical space is a research area which belongs to HCI and is also part of the interactive narrative. The narrative form under the influence of user behavior and technology will face an upgrade.This paper intends to explain the new forms of interactive narrative by arrangement of the narrative, the mapping relationship between physical space and narrative space, and input and output of interactive technology. In this study, natural user behavior as a starting point to explore how to produce a reasonable story by using the user's behavior and interactions. This paper takes the interactive video installation as a practice, summarizes the method of designing the interactive narrative video installation in the physical space, and verifies the usability of the design method.
