  • Expect the new WCAG standards to emphasize a mobile experience that matches what users might expect from a traditional browsing session. This will likely include making your site’s touch screen functions more compatible with assistive technology. 
  • The new standards are expected to raise that level to 400% to help users with low vision navigate sites more smoothly.
  • WCAG 2.1 will likely seek to place limits on where and when pop-ups and similar advertising can appear.

  • For users with motor skill issues, clicking on incorrect links and buttons is a common problem. WCAG 2.1 will likely require improvements in navigation technology that makes it easier both to find the right link and to correct actions if the wrong link is clicked.

    Considering how massively the online landscape has changed in the past decade, it's amazing that international standards for web accessibility haven't been updated since December of 2008. That's about to change. After soliciting and assessing recommendations from the public, the international Web Accessibility Initiative is set to announce version 2.1 of its Web Content Accessibility Guidelines in the middle of this year. As that update draws nearer, there are a few key changes website owners may want to start planning for. (Keep in mind that all WCAG 2.1 changes are tentative.)

    HTML_CodeSniffer is a client-side script that checks HTML source code and detects violations of a defined coding standard. HTML_CodeSniffer is written entirely in JavaScript, does not require any server-side processing and can be extended by developers to enforce custom coding standards by creating your own "sniffs". To get you started, HTML_CodeSniffer comes with standards that enforce the three conformance levels of the Web Content Accessibility Guidelines (WCAG) 2.0, and the web-related components of the U.S. "Section 508" legislation. An auditor interface is provided by a bookmarklet to let you try out these accessibility checks on any web page.

  • One major new piece of work undertaken by WAI is the EC-funded WAI-AGE Project (http://www.w3.org/WAI/WAI-AGE/), a look at the implications of an ageing population for web access, given the older people are more likely to have disabilities and may also be less familiar with new technologies. “Demographics worldwide are dramatically changing at the moment,” says Andrew Arch, who works with Abou-Zahra on WAI-AGE. “The proportions of older to younger people are changing as well as the numbers. We’re living longer, and we haven’t got the support behind us. “Lots of things have got to change in governments and organisations - with an ageing workforce, you have to keep learning to stay accessible.”
  • The WAI-AGE project is partly aimed at finding out whether there are any significant new pieces of work needed to ensure web accessibility for an older population, Arch says. “We’ve looked at what research and user observation has gone on over the decade. There is a pretty big overlap between older people and others with disabilities - sight starts to decline, motor dexterity - and individually these overlap. But with older people there is often a lack of recognition that there is a disability there. For example some people might just say they can’t remember so well, rather than that they have a cognitive impairment. Or people won’t see failing eye-sight as a disability, it’s just ‘part of growing old’. But they are disabilities, and often multiple disabilities.”
  • Having gained a grasp of current research the project returned to guidelines such as WCAG 2.0 to see if any changes might be needed. “A large proportion of the needs of older people are met by the new guidelines, but other things might need to feed into the guidance we will issue on implementing the guidelines, for example guidance on how people prepare content for older people.,” said Arch. “Many older people have not grown up with computers, and may not realise their capabilities, for example that you can magnify text in your browser.”
  • ...4 more annotations...
  • This argument is a development of the age-old mantra from the accessibility sector that people with disabilities want to use the web in the same way as everybody else - “it is a human right recognised by the UN,” says Abou-Zahra. But he recognizes that businesses in particular will also  be interested in the additional business benefits, especially in the current financial climate.
  • “With commercial organisations the return on investment is often an important argument. Well, a few years ago, companies might have said ‘how many older people are online?’ but with demographics changing they know the answer. And with the current surge in mobile phone use there is another incentive, since accessible sites work better on mobile phones.”
  • Another change of style will be a greater separation between the core guidelines and references to specific technologies such as Javascript or browser types, Abou-Zahra says.
  • “WCAG 1.0 was too  technology-specific. Back then HTML was more dominant, and there was less use of multimedia, but today we have a flurry of technologies such as Ajax, so the first lesson we learned is don’t write for a specific technology. Also, in the days of WCAG 1.0 we had to exclude Javascript because it was not sufficiently standardised and  assistive technology could not handle it consistently, but now that has largely changed so you need to include it, to look at how any technology should be accessible. The requirements - such as tagging images with text - needs to apply to any technology you are using.

WCAG accessibility web content standards

shared by Vernon Fowler on 09 Mar 16 - No Cached
  • Perceivable - Information and user interface components must be presentable to users in ways they can perceive.This means that users must be able to perceive the information being presented (it can't be invisible to all of their senses)Operable - User interface components and navigation must be operable.This means that users must be able to operate the interface (the interface cannot require interaction that a user cannot perform)
  • users must be able to understand the information as well as the operation of the user interface
  • robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies

    "The guidelines and Success Criteria are organized around the following four principles, which lay the foundation necessary for anyone to access and use Web content."

  • The label element is not used for the following because labels for these elements are provided via the value attribute
  • This technique inserts new content into the DOM immediately following the element that was activated to trigger the script. The triggering element must be a link or a button, and the script must be called from its onclick event. These elements are natively focusable, and their onclick event is device independent. Focus remains on the activated element and the new content, inserted after it, becomes the next thing in both the tab order and screen-reader reading order. Note that this technique works for synchronous updates. For asynchronous updates (sometimes called AJAX), an additional technique is needed to inform the assistive technology that the asynchronous content has been inserted.
