[Blindmath] Accessible Physics Concepts for Blind Students

Wed Jun 15 02:32:08 UTC 2011

Some helpful links:
WAI-ARIA draft/document
http://www.w3.org/WAI/intro/aria.php

Note that ARIA support still differs across both browsers and screen
readers, and I believe the specification is a final draft,not official
W3C standard yet.
This is the right solution for the future certainly, but just keep in
mind that you may still get complaints for some time (months
probably).
But if everyone shies away from implementing new things because they
have not become a standard, they will never become a standard.
I can't comment on the site in question, but I would've thought using
headings of different levels might help clarify and keep the site
organizied, as well as making site navigation easier.
see the WebAIM article:
http://webaim.org/techniques/semanticstructure/

For math using MathJax (http://www.mathjax.org) or embed MathML for
mathematics will allow users to play math in smost screen readers
using MathPlayer from Design Science (www.dessci.com). MP is IE8
compatible and there's work in IE9 and Firefox compatibility I believe
(Neil Soiffer will comment on that soon I am sure, he is the developer
for MathPlayer).
MathML can also be embossed into braille by both Duxbury DBT and TSS
from ViewPlus (though the preferred source format is Word with
MathML).
In csae you are wondering about PDF, it is not very screen reader
friendly with math, though there have been some experiments with
making MathPlayer work with PDF, and those who can read pure TeX can
use it inside an accessible (tagged) PDF document.
For graphics use SVG for all graphs. This is another area still under
Assistive Technology development, but SVG is a key concept of UDL, U
of Washington has done embossing work as well as APH (as mentioned
above).
SVG and MathML are both core technologies of HTML5 and ePub3 so future
websites and eBooks can create a STEM accessibility world that
hitherto has been completely out of reach for most visually imapred
people.
Of course there has been a lot of the "chicken and egg" situation in
this field. Due to little interest of end users in STEM accessibility
it has been hard to encourage Assistive Technology development and
hard to persuade publishers to consider these formats, but the lack of
available material in accessible formats is the key to increasing
participation and interest from the print disabled community (for
discussion of ptint disabled see http://www.readingrights.org ..
people with visual and cognitive impairments stand to benefit hugely
from multi media interfacing with STEM material).
Getting content authors and professionals on-board with this movement
is key to revolutionizing the accessibility in the field, so welcome
on board.
Final pointer for you would be http://www.access2science.org
This is a relativelynew website but has a lot of information regarding
STEM accessibility, both producing and consuming.
