Editor's Notes
- #3 Switch to social model of disability critical in so many ways, but I want to suggest one that you may not have thought of: If disability is a medical condition, then design will always be a bandaid. But if disability is the outcome of an interaction, then it can be designed. And there are thousands of people around the world who want their work to change the world, to make better interactions. It seems to me that if we can recast accessibility into an aspect of innovation, we will have changed the dynamic, and given the people who create products a way to think about their work as making the world better for even more people.
- #4 Because we both do usability testing, including people with disabilities, we have been thinking about what this relationship means when we are working with a project on the usabiity of the site. We want to report on both accessibility problems as well as usability problems.
- #5 Another way to look at the pace of change and you can see that rapid, accellerating loopy journey of tecnology. But there's also the social impact of new technology and how it fits into our habits, attitudes and culture. Glenda W-H and that change that unobtrusive (and affordable) technology can bring to how we see the problem.
- #6 But here’s the thing. Even with that disclaimer, there are still enough voters to worry about. In 2000 Brennan Adds up to 47M for the first 2, and 105M if we count hearing and language – a type of disability covered by the Voting Rights Act.
- #7 The list of people with disabilities leaves out a lot of voters Older adults – 47.8 the number of people with 2 or more disabilities grows to 26.3% by age 75 and 55% by age 85 Literacy – the secret disability Low-propensity - more likely to be marginalized or minorities
- #8 Scrolling on a computer screen vs scrolling on an ipad In 2005, when we wrote the voting system standards, we banned scrolling. For good reasons. Scroll bars are impossibly difficult, no matter how ubiquituous they are: far from the main visual field small control couinterintuitive motion requires dexterity control requires understanding that there can be more on the page than you can see But in ipads, it all changes.
- #10 Review briefly.. And map UX principles to the standards.
- #11 Ask a different question
- #12 The first way is to find more ways to bring people with disabilities into the creative process. For me, this builds on an increasing emphasis on ethnographic methods of user research – seeing people in context – rather than bringing them in at the end of the process. The images reflect three different ways of doing this: - Innovation workshops as part of the AVTI research project 64 people in 2 workshops, included wide range of abilities - Going out into the community – testing forms at a school and at a library By the way the woman in the wheelchair is not a participant, but our Vietnamese and Chinese interpreter.
- #13 Design for mobile first because... Mobile forces you to focus (November 2009) The idea of mobile first and responsive design sweeping the web design world. Like plain language, this is an opportunity for accessibility to meet forces at work in the general technology design space. It's not only a moment we can capitalize on, but one we can learn from. So when I talk about designing for extremes, I mean that the diversity of devices can also reflect the diversity of assistive technology – and of people
- #14 Instead of designing specialized AT, or thinking of what we do as creating tools only for people with specific disabilities, it's perhaps more interesting to think about what we can learn from extreme needs that exposes solutions for everyone.
