The Construction of Smart Space is an inevitable trend in the development of libraries,and the research on the related issues is of great significance to transformation of smart libraries.The research used content analysis to code and analyze 11 cases of construction of library smart space.First of all,the successful experience of smart space construction is sorted out:perception of users'needs oriented at data,promotion of user experience by intelligent service and optimizing management by space shaping.Secondly,the obstacles to the construction of smart space are excavated:the weak leadership of the library,uneven spatial layout,weak integration and linkage between virtual and real spaces,incomplete and insufficient smart space system.Finally,it is proposed that smart space can be improved by enhancing the main construction capacity of the library,bridging the gap with a decentralized approach,optimizing the technology iteration and service presentation of virtual and real integration,and building a user-centered smart space,aiming at providing inspiration for future smart space construction.
