Tuukka Ojala is a programmer working on the web. He’s also blind. Here are the tools of his trade.
The Government Digital Service have published the results of their assistive technology survey, which makes a nice companion piece to Heydon’s survey. It’s worth noting that the most common assistive technology isn’t screen readers; it’s screen magnifiers. See also this Guardian article on the prevalence of partial blindness:
Of all those registered blind or partially sighted, 93% retain some useful vision – often enough to read a book or watch a film. But this can lead to misunderstanding and confusion
Ire rounds up a bunch of tools you can use to test accessibility, from dev tools to Tenon.
I wrote a while back about how I switched from using a button to using a link for progressive disclosure patterns. That looks like it was a good move—if I use a button, I’d need to use
aria-controls and, as Heydon outlines here, the screen reader support is pants.
Hidden little details that make a big difference for screen readers.
A website is only as beautiful as the underlying markup.
This is such an incredibly useful resource by Steve and Léonie: documenting how multiple screen readers handle each and every element in HTML.
It’s a work in progress, but it’s definitely one to remember the next time you’re thinking “I wonder how screen readers treat this markup…”
Léonie gives a great, clear description of how screen readers switch modes as they traverse the DOM snapshot.
It’s great to see the changes that Facebook’s four-person accessibility team have managed to push through.
This is a great response to my recent post about semantics in HTML. Steve explores the accessibility implications. I heartily concur with his rallying cry at the end:
Derek runs some tests on how screenreaders behave when block-level elements are wrapped in links, which is now legal in HTML5.
Test results for screen readers navigating content that uses new HTML5 elements and ARIA roles.
The results of the second screen reader survey from WebAIM are, once again, required reading.
This list of screenreader survey results is required reading. Conclusion: "there is no typical screen reader user."
A guide to using ARIA roles from the mighty Steve Faulkner.
Steve Faulkner gives a rundown of the current state of play between screen readers and Ajax.
Excellent research into how screen readers respond to empty links (i.e. A elements with no text between the opening and closing tags).
