Much of what I’ve seen on supporting accessibility on the Web has to do with using the right standards: always providing
alt attributes for images, breast for example, or adding semantic ARIA metadata to one’s markup.
As a designer, however, I don’t have much interest in these standards because they don’t seem to address human factors. What’s more interesting to me is understanding how screen readers present the user interface to vision-impaired people and how usable that interface is to them. This would parallel my own experience of designing for non-impaired users, where I use my understanding of human-computer interaction to create interfaces from first principles.
I’ve been meaning to actually get a screen reader and try browsing the Web for a few days to get a better idea of how to build usable interfaces, but I haven’t gotten around to it yet, and I’m also not sure if it’s the best way to empathize with vision-impaired users. In any case, though, my general concern is that there seems to be a distinct lack of material on “how to build truly usable web applications for the vision impaired.” Instead, I only see articles on how to be ARIA standards-compliant, which tells me nothing about the actual human factors involved in designing for accessibility.
So, I’ll be spending some time looking for such resources, and trying to get a better idea of what it’s like to use the internet as someone who is vision-impaired. If you know of any good pointers, please feel free to tweet at me. Thanks!
