摘　　要：目的在考虑任务熟悉性的前提下,研究光照强度和背景颜色对VDT作业中人因可靠性的综合影响。方法设计VDT作业模拟实验,选取180名健康大学生分别在不同变量水平下进行测量,对人因可靠性中的反应时和正确率指标展开方差分析。结果反应时对照度和颜色的变化不敏感,但正确率指标下照度和颜色的主效应和交互效应均显著,且任务熟悉性可削弱其影响。结论 VDT背景呈绿色时,建议双眼周围的水平照度不超过200lx。而在红色背景中,照度不宜低于300lx,且此时忌用绿色和灰色。Objective Under the premise of task familiarity, research on the synthetic effect of illumination intensity and background color on human reliability in VDT operation has been made. Methods The simulated experiments of VDT operation designed were carried out on 180 healthy college students with different faetors＇ evel; then the reaction time and correct rate of human reliability were analyzed by analysis of variance. Results The main effects and interactive effects of illumination intensity and background color are significant on correct rate, but not significant on reaction time, and the familiarity can weaken these effects. Conclusion The horizontal illuminance in green background is recommended to be lower than 200lx. But when the horizontal illuminance is higher than 300lx, it＇s better to use red as background color, instead of green and gray.
