Quantitative analysis of color search performance for designing proper color information

颜色被广泛地用作视觉任务的辅助，例如各种标志、颜色分类、颜色显示。为了改善我们的生活环境质量，创造一个合适的人与环境的界面，重要的是要利用颜色信息的基础上，人类的视觉和行为功能。本研究探讨了不同光照条件下人的颜色搜索和颜色感知，为颜色信息的评价和设计提供了科学依据。实验1：对实际颜色符号视觉搜索的定量分析。首先，检查实际颜色标志的搜索效率。为了分析标志的搜索效率，引入了颜色多样性指数来表征背景颜色的复杂性，并建立了一个颜色搜索的定量评价模型。实验二：中间视觉照明环境下的颜色识别-颜色刺激大小的影响。要正确使用颜色，必须了解在各种照明条件下如何识别颜色。然后，我测量了颜色识别在明视到中间视觉照明与几个主题。研究结果为色彩信息的设计提供了有用的数据。实验3：基于颜色识别数据的视觉搜索绩效评估。最后，在明视觉到中间视觉的照明条件下，颜色搜索任务的性能进行了检查。使用在实验2中获得的颜色识别数据来分析结果。

Colors are widely used as an aid of visual task such as various signs, color classification, color displays. To improve quality of our living environment and make a proper human-environment interface, it is important to utilize color information properly based on human visual and behavioral functions. In this study, I examined human color search and color perception under various lighting conditions and provided a scientific basis for evaluation and design of color information. Experiment 1 : Quantitative analysis of visual searching for actual color signs. First, searching efficiency of the actual color sign was examined. To analyze the searching efficiency of the sign, I introduced the color diversity index to represent complexity of colors in the background and examined a quantitative evaluation model for color searching. Experiment 2 : Color identification under mesopic lighting environment-effect of color stimulus size. To use colors properly, it is essential to understand how colors are identified under various lighting conditions. Then, I measured color identification at the photopic to mesopic illuminances with several subjects. The results provided useful data for the design of color information. Experiment 3 : Assessment of visual search performance based on color identification data. Finally, performance of color search task under photopic to mesopic lighting conditions were examined. The results were analyzed using color identification data obtained in the experiment 2.
