采用E-prime编排认知实验研究照明环境与TFT-LCD视觉显示终端界面背景饱和度的交互效应对视觉绩效的影响。依据字母视力表设计原理制作认知材料,以认知速度与准确率为视觉绩效评价指标。结果发现,照度与饱和度的交互效应对视觉绩效存在显著影响,色温与饱和度的交互效应仅对准确率存在显著影响,三因素交互作用对准确率存在显著影响。结果表明,不同照度、色温下,通过调节显示终端界面背景饱和度可改善视觉绩效。
E-prime choreography experiments were used to study the effect of the interaction between lighting environment and the background saturation of TFT-LCD visual display terminal on visual performance. According to the design principles of alphabetic visual acuity, cognitive material is made to evaluate the visual performance with cognitive speed and accuracy. The results show that the interaction effect of illumination and saturation has a significant effect on visual performance, and the interaction effect between color temperature and saturation only has a significant impact on the accuracy, and the three-factor interaction has a significant impact on the accuracy. The results show that under different illumination and color temperature, the visual performance can be improved by adjusting the background saturation of the display terminal interface.
