Color Coding Research Of Complex Information System Interface

With the development of display and control technology,the interactive mode of complex information system has entered the digital age.In this paper,the digital interface of complex information system is used as the research object to explore the interface color coding method suitable for real control requirements.The purpose of this paper is to make the interface color information meet the demand of actual task and the actual environment for information acquisition,reduce the conflict between human visual limitations and huge amounts of information,avoid mistakes and accidents caused by improper color coding.The research contents of this paper mainly include the following five aspects:Firstly,the operation and design requirements of interface based on complex information system are analyzed.In this part,firstly manipulations under actual control conditions are analyzed,then two kinds of typical information system and interface according to the information categories are studied.Finally,two kinds of typical control tasks are analyzed respectively according to the actual manipulation.Secondly,the development,category and relation of color model,color space and color difference formula are studied,derived from the basic theory of digital color.The interface color coding method for digital display control is selected.At the same time,color model,color space and color difference formula are used to select the color screening and quantization method.Thirdly,on the basis of the ACT-R cognitive model,the actual cognitive operation task flow of the operator is analyzed.Based on the ACT-R cognitive model,this paper decomposes and analyzes the actual operation task flow of operators according to the actual operation requirements and environment.Fourthly,based on the radar information system,the optimal color combinations of foreground and background color are explored.Cognitive researches are carried out under different ambient brightness conditions.By comparing the performance of cognitive performances under different brightness conditions,color difference between foreground and background colors should be greater than 20?E₀₀ in the bright environment,and should be kept between 20?E₀₀ to 80?E₀₀ in the dark environment.Finally,based on the control interface of geographic information system,the optimal color grouping mode between targets is explored.Cognitive researches are carried out under different task conditions.By comparing the performance of cognitive performances in different operation tasks,the range of color difference between the targets color should be between 15 and 50?E₀₀0 or more than 60?E₀₀.
