2015年5月21日,W3C HTML工作组(HTML Working Group)发布了在HTML中使用ARIA(Notes on Using ARIA in HTML)的标准工作草案。该文档实际地指导了开发者如何向HTML文档中添加由WAI-ARIA 1.1规范(Accessible Rich Internet Applications specification, WAI-ARIA 1.1) 所规定的无障碍辅助信息,从而使残障人士更容易获得Web内容和访问Web应用。该文档展示了如何在HTML5.1中使用WAI-ARIA,尤其是如何无障碍的使用由Ajax, HTML, JavaScript及相关技术所开发的动态内容及用户界面。
We invite you to review the First Public Working Draft of Cognitive Accessibility User Research. This planned W3C Working Group Note describes the challenges of using web technologies for people with learning disabilities or cognitive disabilities. It provides a basis for subsequent work to develop strategies and techniques to improve accessibility for these user groups. More information is in the Call for Review: Cognitive Accessibility User Research e-mail. Please send comments by 13 February 2015. (2015-01-15)
2015年1月15日,W3C的独立用户界面工作组(IndieUI Working Group)发布了独立用户界面:事件(IndieUI: Events 1.0)的工作草案更新(updated Working Draft),该工作草案中包含新的事件(Events)以及新定义的技术方法。IndieUI:Events 定义了一组与用户输入方式无关的事件,将依赖于用户输入方式的事件翻译为不依赖于用户输入方式的“高层”简单事件,基于这些简单事件编程可以简化Web应用的设计。例如,如果用户希望向下滚动页面内容,他可以用手指在触摸屏上向下滑动,也可以用鼠标上的滚动球向下滚动,或者使用滚轮,甚至在有些应用中通过语音命令来操纵。在IndieUI中,我们可以定义一个简单的Scroll Down事件,并将上述可能的操作关联到这一简单事件上。这在编写需要面对各种输入设备的Web应用时,将极大简化Web应用的开发。
The IndieUI Working Group today published an updated Working Draft of IndieUI: Events 1.0 – Events for User Interface Independence. This draft includes new events and a refined technical model. IndieUI: Events defines a way for different user interactions to be translated into simple events and communicated to Web applications. (For example, if a user wants to scroll down a page, they might use their finger on a touch screen, or click a scroll bar with a mouse, or use a scroll wheel, or say ‘scroll down’ with a voice command. With IndieUI, these are all sent to the Web app as simply: scroll down.) IndieUI will make it easier for Web applications to work in a wide range of contexts — different devices (such as mobile phones and tablets), different assistive technologies (AT), different user needs. With IndieUI, Web application developers will have a uniform way to design applications that work for multiple devices and contexts. Comments on this Draft are encouraged by 13 February 2015. Learn more from the IndieUI Overview and the Updated Working Draft: IndieUI Events e-mail; and read about the Web Accessibility Initiative (WAI).
An updated version of the Web Accessibility Evaluation Tools List is now available. Web accessibility evaluation tools are software programs or online services that help determine if web content meets accessibility guidelines. Information about features of evaluation tools that help with evaluation is in Selecting Web Accessibility Evaluation Tools. Web accessibility evaluation tool vendors are encouraged to submit information about their tool to the list. Learn more about the Web Accessibility Initiative (WAI).
W3C has published a Candidate Recommendation of the HTML5 Image Description Extension, which defines the “longdesc” attribute that enables web authors to provide longer textual descriptions for complex images. This specification is part of W3C’s work to ensure that the Open Web Platform is accessible to people with disabilities. Please see details in the Call for Implementations: HTML5 Image Description Extension e-mail. Additional implementations are welcome through 26 August 2014.
