Derek Featherstone – Real World Accessibility For Real World People
A presentation given at Web Directions North, Vancouver Canada, January 30 2008.
When we follow the principles of web standards, we write valid HTML and CSS, unobtrusive JavaScript and follow WCAG and other accessibility guidelines. This simple act goes a long way to creating an accessible web site, application or service. At the same time, many sites that don’t utilize all that is good and wholesome about web standards perform surprisingly well when they are used by people with disabilities.
How can we get the best of both worlds to create standards-based solutions that are highly usable for real people (including those with disabilities) in the real world?
In this session, we’ll dissect several examples from real sites and apps to learn about accessibility problems that arise from design and development decisions and what we can do to create a more accessible user experience for all people, regardless of their ability.
When Version 2 of the Web Content Accessibility Guidelines is finally released, the status of Javascript will be quite different to that assigned to it in Version 1.0 back in 1999. Back then, Javascript was to “degrade gracefully”. Currently AJAX offers increased usability for visual users, but may detract from accessibility. In future, use of JavaScript will be encouraged but, of course, must enhance rather than detract from accessibility. During this presentation, Andrew and Grant will demonstrate how Javascript, when implemented well, offers enhanced accessibility. By way of balance, they will also present examples of scripting that causes problems. Importantly, they will provide corrections to the errant coding.
Web Usability is far more complex than User Testing and Interaction Design alone. And while interface design is an important consideration, there’s more to a usable site than what’s on the surface. We all know the importance of accessibility and web standards, so let’s take that knowledge one step further and into the realm of usability. In this session Lisa Herrod will redefine the common definition of usability by introducing a greater focus on accessibility and web standards. By taking a more holistic approach you will soon see why usability is more than skin deep.
