随着美国政府对可访问性的新要求，IBM等公司正在修改其销售产品和解决方案的方法，以确保合规性。信息传递机制必须对所有用户都是可访问的，包括视力、听力、运动或认知障碍的用户。用户从许多不同的来源消费信息。一种越来越流行的信息传播方法是使用计算机和互联网。网络上有大量的文档和图形，任何人都可以随时使用。互联网加上辅助科技，例如网页阅读器，使资讯可以轻易取得，否则这些资讯便会受到限制。然而，虽然互联网的资讯量庞大，可以轻易取得，但它也有其局限性。关于链条的一句老话，它只和它最薄弱的一环一样好，恰当地描述了互联网。除了可检索性和可搜索性的问题外，还有许多其他问题困扰着这一信息载体。无论HTML、DHTML、XHTML和XML如何复杂地呈现信息，从有视觉或认知障碍的用户的角度来看，正文文本中的图形是最薄弱的环节。本演示文稿分为两个部分，探讨了创建和导出图形的方法如何改善有视觉或认知障碍的用户在查看技术文档时的体验：清晰，简洁，结构良好的图表使患有阅读障碍和注意力缺陷/多动障碍（ADHD）的认知受损者能够更好地理解。可缩放矢量图形（SVG）解决方案解决了视障人士面临的许多挑战。
With the U.S. government's new requirement for accessibility, companies such as IBM, are revising their method of selling products and solutions to ensure compliance. The delivery mechanism for information must be accessible to all users, including users with vision, hearing, motor, or cognitive disabilities.Users consume information from many different sources. An increasingly popular method of distributing information is using computers and the Internet. The Web houses volumes of documents and graphics available to anyone at any time. Paired with assistive technology such as Home Page Reader, the Internet makes information that would otherwise be restrictive accessible.However, as approachable as the Internet may be with its sheer volume of information, it does have limitations. The old saying about a chain, that it is only as good as its weakest link, aptly describes the Internet. Beside problems with retrievability and searchability, many other issues plague this vehicle of information. No matter how sophisticated HTML, DHTML, XHTML, and XML present information, the graphics within the body text are the weakest link, from the viewpoint of users with visual or cognitive impairments.This presentation is divided into two sections and explores how a method of creating and exporting graphics can improve the experiences of users with visual or cognitive impairments when viewing technical documentation: Clear, concise, and well-structured diagrams enable better comprehension for the cognitively impaired suffering from dyslexia and Attention-Deficit/Hyperactive Disorder (ADHD). The Scalable Vector Graphics (SVG) solution addresses many challenges for visually impaired people.
