彩色背景下的颜色突显研究

Color Highlighting Research in Colorful Background

颜色突显是指在与视觉搜索任务有关的视觉显示中,采用颜色突出显示多个项目中的目标项目,从而提高视觉搜索效率的一种方法或技术。本文采用视觉搜索任务,以正确率和反应时为指标对单彩色和复杂彩色背景下不同颜色突显的视觉搜索绩效进行了研究。结果表明:(1)在单彩色背景和复杂彩色背景下,颜色突显条件视觉搜索绩效显著优于非突显条件;(2)在浅蓝或浅绿的单彩色背景下,四种颜色突显绩效中,红色突显绩效最好,紫色最差,而在随机彩色背景和复杂彩色背景下,颜色突显绩效差异并不显著;(3)在彩色背景下的颜色突显绩效会受到干扰数字的颜色的影响,其中在单色和随机彩色背景下,干扰目标颜色为黑色时的视觉搜索绩效优于干扰目标颜色为白色时的情景,而在自然彩色背景下,这种视觉搜索优势并不存在。

Color highlighting is a kind of method or technique to improve efficiency of visual search in visual search task. The purpose of this study was to investigate the effect of color highlighting on visual search perform- ance in monochrome colorful background and compli- cated colorful background. The main results of this study included： （ 1 ） According to the monochrome colorful and complicated colorful background, the performances of four types of colors highlighting were significantly better than the non-highlighted condi- tion;（2） According to the light blue background and light green monochrome background ,the performanceof red colors highlighting was significantly better than the performances of other three colors. However, to complicated colorful background, the difference was not significant; （3） According to monochrome colorful background and randomized colorful background, the performance of color highlighting with the interfer- ence color in black was significantly better than the interference color in white. However, to the natural colorful background, this superiority effect did not exist.
