We are a group of students from an HND Computing and Internet Technology course at Yeovil College in the UK, and as part of our final project have decided to develop an intranet for the higher education college network and we have decided to use Moodle. Here in the UK, websites to be used by students in a college have to follow the Special Educational Needs Disability Act (SENDA), and we would like to know what measures have been taken to ensure Moodle is suitable for people with special needs? Would Moodle work on devices like touch screens and screen readers? Could Moodle be navigated with a head pointer, rather than a mouse?
Documentation regarding SENDA can be found here.
My layout design technique incorporates simplicity and a general awareness of page rendering order, as well as using ALT images where possible, so it should be fairly good, but I haven't conciously conformed to any particular accessibility criteria such as SENDA, Section 508, WAI etc, nor has it ever been tested on screen readers as far as I know. There are some plans for XHTML-compliance in the near future which may help.
One way your group could help this project is to perform an audit and report back here with your findings, highlighting specific things that could be done to improve accessibility.
I'll report back with other findings when I have them.
I looked in to Jaws as a text reader, and used it to test some websites. Going from memory, it basically doesn't have a problem, until you hit frames, and then it only reads one, until the user navigates to the next. It isn't always clear when there is more than one frame.
Looking at some parts of moodle, there was a frame, which I stumbled on. This could be replaced with includes, which PHP does quite nicely.
