如今，与可访问性相关的法规和准则一直在加快Web可访问性的改善。加速因素之一是开发和部署可访问性评估工具，用于创作时间和维修时间。他们主要致力于通过分析页面的HTML语法来创建符合符合性的网站，并报告当没有语法错误时，页面是合规的。但是，这种合规的页面通常并不是盲人用户真正可用的。这是因为当前的评估工具仅检查HTML标签是否适当地符合法规和准则。如果此类工具更加关注实际的可用性，尤其是在以时为导向的可用性因素上，例如达到目标内容的速度，了解页面结构的易用性和可通道性，以帮助网络设计师来不仅创建符合符合条件的页面，还可以为盲人创建可用页面。因此，我们决定开发可访问性设计师（Adesigner），该设计师具有通过使用颜色和等级来可视化盲人用户的可用性的功能。可视化功能使Web设计人员可以掌握页面中的弱点，并认识到他们的页面的可访问或无法接近的内容。在回顾相关工作之后，我们描述了可视化盲人用户的可用性，然后概述可访问性设计师的方法。然后，我们使用可访问性设计人员报告对真实网站的评估。讨论结果后，我们总结了本文。
These days, accessibility-related regulations and guidelines have been accelerating the improvement of Web accessibility. One of the accelerating factors is the development and deployment of accessibility evaluation tools for authoring time and repair time. They mainly focus on creating compliant Web sites by analyzing the HTML syntax of pages, and report that pages are compliant when there are no syntactical errors. However, such compliant pages are often not truly usable by blind users. This is because current evaluation tools merely check if the HTML tags are appropriately used to be compliant with regulations and guidelines. It would be better if such tools paid more attention to real usability, especially on time-oriented usability factors, such as the speed to reach target content, the ease of understanding the page structure, and the navigability, in order to help Web designers to create not simply compliant pages but also usable pages for the blind. Therefore, we decided to develop Accessibility Designer (aDesigner), which has capabilities to visualize blind users' usability by using colors and gradations. The visualization function allows Web designers to grasp the weak points in their pages, and to recognize how accessible or inaccessible their pages are at a glance. In this paper, after reviewing the related work, we describe our approach to visualize blind users' usability followed by an overview of Accessibility Designer. We then report on our evaluations of real Web sites using Accessibility Designer. After discussing the results, we conclude the paper.
