Abstract: [Purpose/Significance] To address the trend of transformation in the library service ecosystem, this study constructs a new service model from the perspective of embodied cognition, taking the spatial intelligence service ecosystem as the carrier and emphasizing user physical participation and situational interaction. It seeks to solve the problems of technological fragmentation and user cognitive gap existing in traditional service models, and to enhance the intelligence level of library services and user experience. [Design/Methodology] Based on the theory of spatial topology, integrating cutting-edge technologies such as UWB high-precision positioning, VR/AR virtual-real fusion, and digital human interaction, this research aims to construct a spatial intelligence service ecosystem model for libraries that integrates physical, virtual, and cognitive elements. It also delves into the potential privacy data risks under this ecosystem model and proposes a corresponding protection framework. [Findings/Conclusion] The spatial intelligence service ecosystem for libraries provides a practical and feasible path for the intelligent transformation of libraries, achieving transformations such as three-dimensional enhanced navigation, virtual resource visualization, real-time digital human interaction, and personalized library services, significantly improving service efficiency and user experience. Future research needs to further explore the integration potential of human-intelligence symbiosis, with a particular emphasis on addressing data privacy and ethical risks, thereby fostering the development of the human-intelligence symbiosis models toward a safer and more inclusive direction. [Originality/Value] This article explores and enumerates the application scenarios of the spatial intelligence service ecosystem for libraries from the perspective of embodied cognition, providing inspiration for the transformation of library services from a unidirectional resource provision model to a dynamic symbiotic paradigm of technology integration.
