【摘要】：复杂系统数字界面中的颜色编码对界面设计有十分重要的影响,如何通过颜色编码降低视觉信息混乱、提高认知绩效是优化界面设计中有待研究的课题。针对视觉的层次化感知引导人的注意捕获和视觉行为,在色彩体系和注意捕获理论基础上,通过对视觉感知分层和注意捕获程度的关联分析,提出利用两颜色之间的相互干扰反应时间之差判断其注意捕获程度。采用蒙赛尔色立体中的颜色心理三属性在知觉上的等距离划分,设计颜色的注意捕获试验,结合色差对不同色相、明度和饱和度的视觉感知层次和注意捕获程度进行判定、整合,并对比不同色差大小对认知速度的影响,分析结果表明:黑色背景下,除红色外仅色相不同的颜色在视觉感知上处于同一层;随着明度和饱和度的减少,视觉感知层次降低;目标与干扰物的色差固定时,低明度颜色对比高明度颜色对有更好的识别绩效。以飞机辅助起飞系统弯道情境仿真界面设计为例,验证了距离高饱和的目标色相同色差时,低明度背景上的目标认知绩效优于高明度背景。
[Abstract]:Color coding in digital interface of complex system has a very important impact on interface design, how to reduce visual confusion through color coding. Improving cognitive performance is a subject to be studied in the optimization of interface design. Aiming at the hierarchical perception of vision to guide human attention capture and visual behavior, based on color system and attention capture theory. The correlation analysis of visual perception stratification and attention capture degree is carried out. It is proposed to judge the degree of attention capture by using the difference of the time of interaction between the two colors, and to design the color attention capture experiment by dividing the three attributes of color psychology in the color stereoscopic into the same distance in perception. Combined with color difference to determine the level of visual perception and the degree of attention acquisition of different color, brightness and saturation, and compare the effect of different color difference on cognitive speed. The analysis results show that: under the black background. Except red, the colors with different colors are in the same layer on the visual perception. With the decrease of brightness and saturation, the level of visual perception decreases. When the color difference between the target and the object is fixed, the low brightness color contrast with the high brightness color pair has better recognition performance. Take the aircraft auxiliary take-off system bend scene simulation interface design as an example. It is verified that the target cognitive performance of low brightness background is better than that of high brightness background when the target color is the same color difference with high saturation distance.
