Research On Multiple Visual Information Coding Of Situational Interface Based On Complex Network Theory

In a situational awareness system environment that is oriented to complex tasks,with large information carrying capacity and multi-dimensional presentation,whether the visual presentation of information is scientific and reasonable directly affects the efficiency of humancomputer information interaction.This paper takes the civil situation interface AIS information service platform as an example,and uses complex network theory as the research foundation to explore the optimization design method of multiple visual information coding suitable for general situation interface to improve the usability of the interface.The main research contents of this paper are as follows.Firstly,the implicit association representation method of situational interface information primitives is established.This paper analyzes the basic properties of complex networks,four static statistical characteristics,common network models,and communities.Based on this theoretical basis,the AIS information service platform interface information system is abstracted into a complex network.By analyzing the typical operation tasks of the interface,the explicit association between "task-information" is transformed into the intrinsic association between information graphic elements,and the interface information graphic element network is built on the basis of this data and output visually,so as to realize the explicit representation of the implicit association of interface information graphic elements.Then,an optimal design method of multiple visual information coding based on interface information hierarchy is proposed.Based on the research on the centrality index of the interface information element network,the evaluation model of node comprehensive importance degree is constructed and the pyramid interface information hierarchy structure is constructed.The color coding method based on perceptual hierarchy and the layout coding method based on perceptual order were used to optimize the information of different hierarchical structures of the interface,and the layout optimization and color optimization schemes were obtained.Finally,through eye-tracking experiments,the performance evaluation of the layout optimization plan and the color optimization plan were carried out.The analysis results of the fixation time,the number of fixation points,the hot zone map and other indicators obtained: the interface layout coding based on the comprehensive importance evaluation of the nodes and color coding optimization design can effectively improve interface usability and cognitive performance.The research results of this paper can provide reference for the optimal design of multiple visual information coding of situational interface based on complex network theory.
