New issue 320: Accessibility problems with kallithea and screen readers

Michael Taboada:

Hi,
First off, I am blind, so use a screen reader to access my computer. On linux I 
use orca, on windows I use NVDA or Jaws for Windows (depending on the thing I'm 
doing), and on mac I use the built in voice over.
The problem is, kallithea has some (relatively major) accessibility problems. 
I'm going to provide some general problems, and then give some examples of 
specifics:

Generally, many items are clickable elements, instead of links, and screen 
readers do not do well with such elements. There are also links that are 
clickable links, meaning you can press enter on them, and they will load a 
page, but clicking them either opens a menu under them, or loads a different 
page. Also, there are some sections where clickables (which should turn into 
links as with the others) flash on the screen and disappear. This is most 
prominent with user/group selection fields, where you type a search (a whole 
name, part of a name, etc) and then click the item you want. The problem here 
is, I would guess, that upon exiting the field, a search list pops up, but, the 
screen reader interacts in such a way that the javascript thinks you have moved 
your mouse away from the list or something so almost immediately closes it. 
Also, some sections are not labelled properly. This is mostly seen, once again, 
in the user/group selection UI, though this time in the permission selection 
(none, read, etc). I also noticed that even well labelled radio buttons (such 
as the apply to which children selection on repository group permission pages) 
don't seem to think you've selected them, even when I use the space bar to, so 
when clicking save it reverts.

Now, some suggestions how to get around these issues:

For clickables, basically the only way to fix them is to make them into a 
"true" clickable element (meaning an element that is natively accessible with 
the keyboard without screen reader hacks), such as a button or link. The 
alternative is to write custom javascript to detect keys being pressed, but 
let's just not go there. For the links that do different things when clicked, I 
would say they need to either be re-written to accept a keypress (such as enter 
or space bar), but only expand, not load the new page. That last part is more 
of a usability issue, but nevertheless. This would kill two birds with one 
stone, one being making it much easier for screen reader users to access the 
menu, another being that instead of having to click (or press a key), load 
another page, then re-navigate to the same spot where you were, you can just 
press a key and go. The radio buttons need to either have a label element, or 
be put in a "true" html table, instead of just text being aligned with css or 
similar. This would make most screen readers read the proper label, rather than 
just "radio button" or "<name> radio button". Preferably actually both of these 
would be done, as tables provide much more structure for the thing that is, 
essentially, a table for screen readers, and the labels would guarantee that 
even slightly less well-behaved screen readers would work well with them. As 
for the flash menu problem, the only real thing I can say there is that the 
menu can't disappear when it thinks the mouse has been moved off of it, or 
otherwise it just needs to realize when a screen reader is doing the "moving" 
(much harder than is necessary imo).

Lastly, for better usability for screen reader users, headings should be added 
in key places. One big one that is only done on a few places (like a specific 
repositories page) is to put a heading at the top of the content (above the 
links for the repository, for example). This is already done in repositories, 
but almost nowhere else. Other places could include above the settings fields 
on a setting page, at critical points in a page, etc. It just makes screen 
reader users' lives much easier as they can press one or two keys to move to 
the right place, as opposed to having to down arrow 10,20,30+ times.

I will add to this issue if I find anything else, but I think that list gives a 
pretty good summary of what I found wrong with the accessibility, and more than 
enough to work on :-).

Thanks!

-Michael.
