in my math preparation I used latex extensively and now I am able to read latex code as I read liniar text. In fact last two years in university i've used infty reader to transform printed math material to latex source and to read it. Also there is a subset of latex named hrtex meaning human readable tex and infty reader know also to give such source from a printed/image material with math. But this kind of reading math demands a lot of experience with latex to quickly transform things like f_n(x)=\sum_{i=1}^{n}{x^i} ----- Original Message ----- From: Dorene Cornwell To: programmingblind@xxxxxxxxxxxxx Sent: Friday, November 21, 2008 7:36 PM Subject: Re: accessible math The thing Jim Dunleavy is talking about is LaTeX, a text-based language used by LOTS of people in math and science to generate equations and to do other kinds of formatting / typesetting. Just guessing, the way Alt text would work is for the Alt text / label to be the actual LaTeX code that produces the different figures. A reader needs to understand the LaTeX code in order to parse out what symbols are involved, but typically someone working in the field might know that anyway from writing the code to produce their own equations. The sighted user just sees whatever figure is created by the LaTeX code and is indifferent to the code. As for whether or not everything on Wikipedia follows a given convention, I assume that is greatly to be hoped for but not guaranteed, just due to the nature of Wikipedia. Probably I could do some actual testing/ research to verify these points, but perhaps this is enough to help you get started.

I don't see any alt tagging going on that makes the equations easy to read. What is the language they use to write Math on Wikipedia? Thanks.
