Level Evaluation of Data Visualization Platform Construction for Digital Large Screen
Human processing speed of visual information is much higher than that of textual information.With the help of visual charts and models,data analysis results can be presented more concretely and accurately.This paper avoids the subjective presentation of specific business on large screens,and constructs three levels of data visualization from the per-spective of human-computer interaction:board level,speech level,and system level.From the perspective of the presenta-tion effect of the large screen,the Level-1 to Level-5 data visualization levels have been analyzed and defined,providing a new perspective and direction for the construction of large screen data visualization on how to evaluate their own construc-tion level,and also helping to shape industry standards.
