摘　　要：针对人机显示界面中字符编码的工效设计问题,以封闭模拟驾驶舱为基础,采用32名被试开展静态模拟实验,选取反应时间和反应正确率为工效评价指标,得出不同光照水平、颜色匹配和字符高度下显示界面呈现的中文、英文、数字及符号的辨识绩效.实验结果表明:中/英文、数字和普通符号的辨识绩效差异显著;0～600lx范围内4个水平光照变化对字符编码辨识绩效影响较小;颜色匹配方式对字符编码辨识绩效影响显著,黄/白、绿/青的字符/背景色匹配方式辨识绩效较差,在字符编码设计中尽量避免使用.通过实验结论及对实验数据的深入分析,建立显示界面字符编码设计的数学模型,为飞机驾驶舱人机显示界面编码设计提供参考.Aiming at the problems of character design on the human-machine interface,lots of static simulation experiments were taken based on a closed simulated cockpit.32 subjects were participated in the experiments.Reaction time and correct rate were used as ergonomic evaluation indexes.The identification performances of Chinese,English,numbers,and symbols which were shown on the display interface under different illumination levels,color matching and character heights were obtained.Result indicates that the identification performances of the Chinese/English,numbers and normal symbols significantly different.Illumination between 0 to 600 lx has little effects on the character identification performances.Color matching has significantly effects on the characters identification performances.The identification performances of yellow/white and green/cyan are worse and should not be used in character coding design.On the basis of conclusions and deep analysis of the experiment date,a mathematical model of character coding design on the display interface is established,which will provide a reference for coding design of aircraft cockpit human-machine interface.
