Research On Design Of Visual Narrative Structure Driven By Spatio-temporal Data

In recent years,big data visualization has become a research application hotspot in academia and industry,and it has also brought new challenges to technicians and designers in the field of data visualization.In recent years,a large number of research results have been obtained in the visualization academic and application industry,focusing on branch research such as visualization code technology,visualization performance calculation,and visualization representation mapping research.Unfortunately,the existing data visualization design research focuses on the field of data visualization representation.In recent years,although there have been researches around visualized data narratives,most of them are based on the form of representation,and there is a lack of research on the basis of narrative visualization that conforms to the user's cognitive structure logic as the main breakthrough point.Therefore,starting from user cognition,this article explores the optimal narrative visualization method of spatio-temporal data and the preference of users with different cognitive styles for narrative structure based on theory combined with behavioral experimental research,and comprehensively summarizes spatio-temporal data.The narrative structure construction design principles provide a certain reference for the visual narrative structure design of spatio-temporal data.First,based on the three perspectives of user information cognition,this article expounds the basic theories of user cognition at different levels based on visual channel acquisition from information behavior cognition,information visual cognition,and information brain cognition.Secondly,from the perspective of visualization designers,it sorts out the research and application of narrative theory in different visualization situations,and summarizes the theoretical basis of narrative visualization and the usability principle of narrative structure design.Thirdly,from the perspective of user behavior research,the user's cognitive behavior performance on time data and spatial data is evaluated through behavioral experimental measurement indicators.In this part,based on the composite representation of spatiotemporal data in different levels of visual narrative structure,experiment one explores the impact of spatiotemporal data visual narrative structure on user cognitive performance based on vision,and derives the optimal narrative presentation structure of spatiotemporal data method:Experiment two explored the matching relationship between cognitive style and visual narrative structure based on interaction,and obtained the correlation effect between user's field cognitive style and visual narrative structure through behavior experiments.Finally,from the perspective of design practice,based on the actual data visualization design requirements,the design support methods derived from the theory in this study combined with behavior experiments are comprehensively applied to the actual data narrative design,providing an interface design that combines spatio-temporal data visualization and interaction The design case reference.Through the combination of cognitive theory,narrative theory and behavioral performance experiment,this research progressively and comprehensively researches the data visualization narrative structure,which has certain reference value for the design of the spatio-temporal data narrative structure of the visualization interface.
