Development of visibility estimation model using colors and contrasts

万维网的迅速传播增加了网页可见性研究的重要性。前景和背景颜色的组合是提供足够可见性的重要因素，在开发可访问网站时应考虑颜色组合可见性的评级。本研究首先使用心理学方法，即配对比较，对几种网络安全颜色组合的可见性进行了检验。视觉刺激为18种彩色和3种消色差的网络安全色。研究对象的年龄从21岁到75岁不等，他们都有正常的色觉。实验对象同时看两种不同颜色的人物，并被要求辨认出哪一个他们看得更清楚。为了检验颜色组合的心理排名和视觉感觉之间的关系，每种颜色组合都通过瑟斯通的配对比较技术对可见性进行评分。更多是通过将韦伯-费希纳定律应用于前景颜色的亮度而推断出来的。结果表明，前景色的亮度影响网络安全色的可见性；然而，光靠亮度不足以做出能见度评级。色度和色度饱和度在彩色网页安全颜色可见性的评级中也是必要的。其次，针对个人用户的可视性，提出了一种带有自动色彩校正（调色板更改）的网页浏览方法。由于对所有可能的颜色组合进行调查是极其困难的，因此需要一个估计颜色组合可见性的模型。在我们的研究中，SOM（自组织地图）被用来解决这个问题。提出了一种基于SOM的网页浏览个人可见性预测方法。该方法以CGI （Common Gateway Interface）软件的形式在Internet的HTTP服务器上实现。我们发现CGI对网页浏览的自动色彩校正很有用。这表明SOM可用于提高可见性和个人可用性。少

The rapid dissemination of the World Wide Web has increased the importance of web page visibility research. The combination of foreground and background colors is an important factor in providing sufficient visibility, and the rating of color combination visibility should be considered when developing accessible websitesIn this research, firstly, the visibility of several web-safe color combinations was examined using psychological methodology, i.e., paired comparison. Visual stimuli were 18 chromatic and 3 achromatic web-safe colors. Subjects ranging in age from 21 to 75 years were recruited, and all had normal color sensation. Subjects looked at two different colored characters simultaneously and were instructed to identify which they could see more clearly. To examine the relationship between psychological rankings of the color combinations and visual sensations, each color combination was scored with regard to visibility by Thurstone's paired comparison technique. Visual sensation … More was deduced by applying Weber-Fechner's law to the luminance of the foreground colors. Results indicated that the luminance of a foreground color influenced visibility of web-safe colors ; however, luminance alone was not sufficient to make a visibility rating. Chromaticity and chroma saturation are also necessary in the rating of chromatic web-safe color visibility.Secondly, a Web browsing method with an automatic color correction (palette changing) for personal user's visibility was proposed. Since an investigation of all possible color combinations is extremely difficult to conduct, a model for estimating color combination visibility is needed. In our study, SOM (Self-Organizing Maps) was used to solve this problem. We proposed a prediction method with SOM for personal visibility on Web browsing. This method was implemented as CGI (Common Gateway Interface) software on a HTTP server of the Internet. We found that the CGI is useful for automatic color correction of Web browsing. This indicated that SOM was available for improving visibility and individual personal usability. Less
