项目摘要

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

万维网的迅速传播增加了网页可见性研究的重要性。前景色和背景色的组合是提供足够可见性的重要因素，在开发无障碍网站时应考虑颜色组合可见性的评级。配对比较视觉刺激为18种彩色和3种无色网络安全颜色。受试者的年龄从21岁到75岁不等，所有人都有正常的色觉。受试者同时看两个不同颜色的字符，并被指示识别他们可以更清楚地看到。为了研究颜色组合的心理排名和视觉感觉之间的关系，每种颜色组合的能见度方面的Thurstone的配对比较技术。视觉感受 ...更多信息通过将韦伯-费希纳定律应用于前景颜色的亮度来推导。结果表明，前景色的亮度影响网络安全颜色的可见性，但是，单独的亮度是不足以使可见性评级。色度和色度饱和度也是评价彩色网页安全颜色可见性的必要条件。其次，提出了一种基于个人用户可见性的自动颜色校正（调色板改变）的Web浏览方法。由于调查所有可能的颜色组合是非常困难的，需要一个模型来估计颜色组合的可见性。在我们的研究中，SOM（自组织映射）是用来解决这个问题。我们提出了一种预测方法与SOM的个人可见性的Web浏览。该方法在因特网的HTTP服务器上作为CGI（公共网关接口）软件实现。我们发现CGI对于Web浏览的自动颜色校正是有用的。这表明SOM可用于提高可见性和个人可用性。少
