[Blindmath] math being visual (was: Typing in Nemeth Braille)

Wow, that is wierd.  Saying that math is too visual, for it to be 
practical for blind people -- that's just wierd. Personally, i've never 
heard that and I doubt any decent mathematician would sayit. Have these 
people never heard of a "Thought experiment"?

In fact, I think it's not just wrong, it's backward.  Being blind gives 
you an advantage especially in geometry. I've experienced this first 
hand. If stuck in a situation where they can't draw a diagram, sighted 
people do very badly on geometric puzzles. Same is true if the problem 
involves something difficult to draw like a three dimensional puzzle. In 
those situations, blind people are at a considerable advantage. The 
problem blind people have with math is a communication problem, not a 
conceptual one. It it was commonplace for geometry to be taught with 
tactile representations of the concepts, blind people would be at an 
advantage.

The idea that math is too visual on a basic level strikes me at 
completely backward at every level of mathematics from understaninding 
the difference between the numbers one and two all the way up to the 
math involved in particle physics. The number three, for example, is a 
concept, not that symbol we use to depict it. Three can be the number of 
marbles in a box but it is not the lumpy symbol we use to depict it.

I once got into a debate, of sourts, with a physics professor because i 
claimed that the meatball like depiction of the atom is  harmful. That 
depiction tends to make students think of sub-atomic particles as little 
balls with the atom being proton and neutron balls clumped together in 
the middle   and little electron balls flying around it like flies. But 
it's not really like that at all. And when you have to start 
understanding things like the Heisenberg Uncertainty Principle and the 
double-slit experiment, it gets in the way.

However, if you try to get the book digitally from them, they will give you a PDF, which you cannot fully access. I think that we are having these access issues because a big portion of the cited population believes that blind people have no right to expect success and Matt. I keep hearing all the time that math is just too visual and that the best blind people can expect is to learn basic algebra, but my experience with Matt has shown me that math and itself isn't visual. Sighted people might feel the most comfortable with a visual representation, but that in no way means the subject itself is visual. Also, I've known plenty of blind people who went way past calculus and use their skills in engineering and computer science. If publishers thought about accessibility from the beginning, it wouldn't b

ly difficult or costly to make sure that blind people as well as other populations can have access to math electronic text.

I have prepared tactile diagrams for several VI students that I work with, and they have found the diagrams to be extremely helpful.  I put a small amount of Braille on the diagrams (just enough to be able to create a separate legend with more information about the diagram).

It's not quite ready for testing yet, however.  I will make an announcement when it is ready, because I will be looking for students in math or math-intensive science courses to test this software.

Also, my brain can't think correctly if I have to work from right to left. I don't know if those math needs are common among blind people, but you could try them to see if it helps. Oh, and another thing is that it might help to get text descriptions of diagrams and represent things algebraically rather then graphically as much as possible.
