头盔瞄准数字显示界面的设计关系到飞行员的认知绩效。由于头盔瞄准界面透视显示的特殊性, 其实时变化的背景对于前景色的选取提出了新的要求。通过实验手段, 以游标敏锐度为测量方法, 通过反应时间和正确率的数值, 在典型天空背景样本中对比了前景字符在明度和饱和度两个维度上的相对较优值。实验发现, 头盔瞄准界面在白天和全天候使用状况下, 字符色彩HSB值(120° 33% 33%)和(120° 99% 33%)的色彩识别性较好; 在夜间使用情况下, 字符色彩HSB值(120° 33% 66%)的色彩被识别性较好, 为头盔瞄准界面色彩设计提供了科学的依据。

This paper focuses on the design of Helmet-Mounted Display(HMD)digital display interface, which is related to the recognition performance of the pilot. Due to the specificity of the HMD see-through display and the changing backgrounds, there are new demands for forecolor selection. Through experimental means, by taking vernier acuity as a measurement method, and the accuracy and reaction time as the indicators, we made comparison to the relatively optimal values of forecolor symbols under conditions of brightness and saturation of the typical sky background samples. Experimental results showed that: 1) The color HSB value(120° 33% 33%) and(120° 99% 33%) were better recognized under the daytime and all-weather condition;and 2) The color HSB value(120° 33% 66%) was better recognized during the night time. The conclusion provides a scientific reference for HMD aiming interface design.
