Research on Data Visualization Design for Police System

The increasingly complicated police work requires increasing information collection, analysis and transmission of the daily police system. From the design point of view, this paper intends to study how to improve the effectiveness and efficiency of data information transmission in police system. By analyzing the objectives and requirements of data information transmission in police system, from the perspective of user experience, the data visualization design model is optimized, the data visualization design principles are deduced, and the laws of human vision and cognition are combined to study the data visualization design strategy of police system to guide design practice. The verification results show that from the perspective of user experience, data visualization design practice can be effectively guided by the design scheme combining human vision and cognitive laws. The design practice process and results show that police data information can be efficiently conveyed, the user experience of police staff can be enhanced, and the efficiency of police work can be improved, based on the user's visual and cognitive laws of data visualization design.
