Urban public cultural space interactive design is an effective medium for human-city surroundings interplay and influence. Space is step by step turning into an object of verbal exchange and interaction with people, rather than just being seen as space. This learn about comprehensively reviews and analyzes the concept of urban public cultural interactive design. Based on the literature, this find out about makes use of the grounded theory method to explore the characteristics, methods, and effects required for urban public cultural space interaction, and constructs a set of urban public cultural space interactive plan method models. The mannequin was once examined via empirical evidence of urban public cultural space interactive design. Based on the textual content facts of 50 cases of public cultural space interactive layout gathered from layout internet site platforms, semi-structured interviews had been performed with teachers from home sketch schools and enterprise designers to construct a theoretical mannequin the usage of grounded theory. The consequences confirmed that through the coding steps of grounded theory, 41 initial concepts, 21 initial categories, 6 main categories, and 1 core class had been obtained. The following two conclusions were drawn from the research: (1) Urban public cultural space interactive design has certain strategies: features (multimodal interaction., full-sensory interaction, experiential interaction), methods (user experience design, multimedia interactive technolog), and effects (gamification interaction, contextualised interaction interaction.). Therefore, the strategy has a certain stage process: guiding use and producing effects. (2) Currently, the interactive design of urban public cultural space has gone through the improvement procedure of beginning and preliminary deepening. In the future, the interactivity of urban public cultural area need to focal point on person wants as the guide, think about the integration from function to form to content, and deliver higher non secular enjoyment and pleasure to the audience. This research has certain theoretical significance for the interactive design of urban public cultural space.
