色彩构成对图形符号视觉搜索效率的影响

摘要

在人机交互界面设计中，色彩编码是一种非常有效的信息呈现方式。为进一步提高图形符号的视觉搜索效率，通过一项视觉搜索实验，重点考察了色彩数量和干扰项色彩是否一致对图形符号搜索时间的影响。实验结果表明，增加构成图形符号的色彩数量会在一定程度上降低视觉搜索效率，而利用色彩增大图形符号之间的差异则会在更大程度上提升视觉搜索效率。%Color coding is a very efficient method for presenting information in the design of human-computer interaction interface. In order to further enhance the search efficiency of graphical symbols, a visual search ex-periment had been arranged to mainly investigate how the color quantity and the consistency of the distracters’ colors will affect the reaction time. The results show that the increase of color quantity in graphical symbols will reduce the visual search efficiency on some level. However, use color to enlarge the difference between graphical symbols will increase the visual search efficiency to a greater extent.
