Abstract：[Purpose/significance] To solve the current dilemma of emphasizing form over knowledge in immersive
reading experience scenarios of public libraries, return to the core of knowledge transmission and cultural inheritance,and provide theoretical and practical guidance for the high-quality construction of immersive reading experience scenarios in libraries in the intelligent era. [Method/process] This paper analyzes the roots of the formalization dilemma of scenarios, defines the connotation and motivation of knowledge reconstruction, constructs a three-dimensional and two-step knowledge reconstruction model based on four core theories, and conducts practical verification with relevant excerpts from Tien-kung Kai-wu as a case. [Result/conclusion] Knowledge as the core is the core orientation to break the dilemma, and the constructed model can achieve accurate adaptation of knowledge to readers, technologies and scenarios; case verification shows that the model is operable, and knowledge reconstruction is the key path to promote the transformation of scenarios from sensory experience to cognitive improvement and highlight the core functions of libraries.
