I had bookmarked Knowability as something I ought to look at, and finally I did. The first thing that caught my eye was a piece complimenting Apple's iPad for its accessibility. Having caught the iPad off base with regard to a wimpy keyboard, unsuitable for those needing high contrast, I wondered about the writer's eyes. How did he miss this? If sighted, he should have spotted the tiny letters and thin outlines. If using a screen reader, of course he would miss it. In that case, shouldn't he have a disclaimer saying what he did not check for? Meeting all the guidelines may not be enough. Perhaps the industry needs a check list of what is done for each type of disability. For poor contrast perception, bold keyboards should head he list. For poor acuity, word wrap is needed for when we enlarge or need a narrow column. Attacking accessibility disability by disability brings out the accommodations needed. I have a pretty good idea of what can be done for eye readers, but no idea of what can be done for ear or finger readers. Where can I find that?
