Research on assistive software for the colorblind

色盲是一种表现型，8%的男性人口患有色盲。正常人很容易分辨的两种不同的颜色，对色盲来说却很难分辨。在现代社会，由于在我们的文档中颜色的使用越来越频繁，色盲正在成为信息差异的来源，将正常人认知的颜色传递给色盲是很困难的。我们认为，在传递信息时，在大多数情况下，发送作者的意图背后的方式组合使用的颜色是足够的，而发送物理属性的颜色是不够的。提出的SmartColor系统是一种重绘技术。它将彩色文档重新绘制，以便色盲者能够最佳地识别作者的着色意图。为此，SmartColor系统还将作者的意图作为一组期望函数的数学公式。在这种情况下，寻找最佳的重绘可以形式化为可取性函数的最大化问题。SmartColor技术已经通过许多例子进行了测试，包括石原的色盲测试图表、彩色网页、彩色文档和彩色图表。

Colorblindness is a phenotype that 8% of the male population is suffering for. Two different colors that are easily distinguished by the normal people can be difficult for the colorblind. In modern society, due to more frequent use of colors in our documents, colorblindness is getting to be a source of information differentials Transferring color cognized by a normal person to a colorblind person is difficult. We assume that in transferring information from one to another, in most cases, sending the author's intention behind the way combined use of colors suffices while sending physical attributes of the colors is not. The SmartColor system proposed is a repainting technology. It takes a colored document and repaints it so that the colorblind person can optimally recognize author's coloring intention. For this purpose, SmartColor system also takes author's intention as a mathematical formulated set of desirability function. In this setting, finding the best repainting can be formalized in terms of maximization problem of the desirability function. SmartColor technology has been tested with a number of example including Ishihara's colorblindness test charts, colored Web pages, colored documents, and colored charts and graphs.
