Research On Visualization Design Of Government Affairs Big Data Supervision Platform Based On Situational Awareness

Along with the coming of the era of big data and the deepening of the global information,intelligence,wisdom,e-government and other city has become an important trend of the development of,is also a country is to promote the important strategic direction,this level put forward higher challenge to the electronic government affairs,and government regulation of big data platform as the government supervision and management of the effective means to society,the optimization and upgrading is imminent.The rapid development of computer and Internet technology,the constant maturity of visualization technology and the wide application of cognitive psychology provide good technical support and theoretical guidance for the improvement and optimization and upgrading of government big data supervision platform.This paper introduce the theory of situational awareness to the government regulation of big data platform of visual design,and set up based on the regulation of situational awareness of the big data platform visual perception model,and through to the situational awareness of the influence factors of three stages,and in-depth analysis and study of government regulation of big data platform,mining and its matching the visual elements,and the visual elements in different stages of the child elements in situational awareness assessment,analysis,summary for the corresponding design strategy,are in for the big data platform regulated situational awareness level to provide the reference and reference.Thesis first of all,from the perspective of the cognitive psychology,research to improve the user's decision-making theory of situational awareness,from the visual design into the government regulation of big data platform,study and demonstrated the relationship between the three,through the visual design support situational awareness process of three stages: perception,cognitive layer,policy makers,with the combination of government regulation of big data platform of visual design,based on situational awareness of government regulation of big data platform visual perception model.Secondly,through the investigation and analysis of the users of the government big data platform,the problems and demands of the platform are obtained and the user model is established.Then,through the analogy analysis of the government big data platform and combining with the influence factors of the three stages of situation awareness,the visual design elements matching the situation awareness are mined.Furthermore,the design elements are analyzed to obtain the visual design sub-elements,and appropriate evaluation indexes are selected in each stage according to the theory of situational awareness,and the visual layout and infographic pattern sub-elements are evaluated and analyzed at three levels in the process of situational awareness through experimental design.By sorting and analyzing the data,the design strategy of visualization design of government big data supervision platform based on situational awareness in three aspects of visualization layout,visualization information diagram and visualization view interaction was obtained,and the visualization model was effectively verified.Finally,the design strategy is used to guide the design practice of nanjing credit information supervision platform,and to analyze and evaluate it.It is hoped that government personnel can quickly and accurately perceive important or abnormal information through the government big data supervision platform,correctly understand and recognize the current situation,and make correct decisions through the judgment of the situation.
