面向色盲人群的导视系统色彩无障碍设计研究

Color Barrier-free Design of Guide System for the Color Blind

目的从提高色盲人群色彩识别能力的角度,探讨导视系统色彩无障碍设计的具体方法。方法采用色觉模拟器,将正常色觉人群与色盲人群的色彩识别效果对比分析。结论采用色盲人群眼中色相变化较小的黄色和蓝色,采用明度对比强烈的色彩组合,注重色彩与图形的搭配,不以颜色作为唯一的识别编码,为色盲人群构建了能与正常人共享导视色彩信息的途径。

The work aims to discuss the specific method for the color barrier-free design of guide system from the perspective of improving the color recognition ability of the color blindness group. Chromatic vision simulator was used to compare and analyze the effect of color recognition between normal color vision group and color blindness group. The yellow and blue of small hue change in the eyes of color blindness group are used. The color combinations of sharp lightness contrast are applied. The attention paid to the collocation of color and graphics and the color not as the only recognition code construct the path to sharing guide color information with normal people for color blindness group.
