accessibility elderly general WCAG 2.0

  • 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.”

  • 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.
