[Blindmath] suggestions for accessible 3d graphing paper giids

[I. C. Bray]

And just when you thought all the sighted people lived richer lives than the 
blind...
Facinating... utterly Facinating!!!!
We should have a total blind-educators retreat... I mean really... bring all 
math geeks, and geometry nerds, and blind pursuers of The Newtonian Archaics 
together for a week of pocket-protector melting math fun!!!

Wow.. Thanks for the honesty, and candor, guys...

Ian

: By the way,Andy,I have been sighted all  my life and I can't draw in 
perspective!
:
: In art class we were taught to draw what we  see. They would put out an 
apple,an orange, and a bottle for us to copy. Good joke. My pictures looked 
like circles laying on each other. As a kid when I had to illustrate my 
compositions, I always would  draw what I could draw, a tree trunk. No 
matter what the story was about! I never understood shading, either.
:
: Would you all forgive me if this sounds patronizing??!! The sighted, 
including myself, will never fully understand the richness of the textures 
that the blind experience, the sound of shadows, the boldness of smells, 
good and bad, and the layers of sound(the way i think my students may have 
learned to hear..I hear noises in the hallways, for example,but my students 
want the door closed. I THINK it is because that is not just noise and 
indiscriminate voices as it is for me. I THINK it is because they are 
hearing the noises in layers, if you will...dimensions??perspective??
:
: Goodness forgive me! I forgot this is a math site, so I may have gone too 
far off topic.
:
: Bottom line, when we have to understand pictures of solids, I show my 
students the picture,and then hand them a solid. The AHHA I hear when I 
place the solid in their hand is confirmation to me that the picture is 
lame, but the solid is worth a 1000 words!

: I didn't even know the word "perspective" until I was in college. Early in

: those 3D pictures was because I wasn't trying hard enough. So I tried to
: imagine how I could take a 3D object and make it into what was on the 
paper
: - by flattening it, of course. If I flattened a sphere, fore example, I
: would get a circle, which is pretty much what they would show when they
: meant sphere, but if I flattened a box I would never, ever get that 
strange
: thing that was on the page. Maybe I was supposed to unfold it like a
: cardboard box? I really tried to solve this puzzle but couldn't. A sighted
: tutor at the Texas School for the Blind recently told me that he could 
teach
: people who were blind from birth to interpret these representations, but I
: have never once heard of someone like myself being able to comprehend 
them.
: I've heard of at least one person memorizing the basic shapes, but no real
: understanding had taken place. Has anyone who has never seen been able to
: touch a raised 3D picture and truly know what it's supposed to represent?

: People don't realize that drawing in perspective is an invention.
: Before some time around 1300, when creating  paintings, artists didn't
: regularly even do things like make objects smaller to make them look
: like they were further away. These days, sighted people take this
: concept of perspective for granted but for most of human history, it
: didn't even exist.
:
: I work on the 5th floor in  the math building on the campus of the
: University of Wisconsin. On the wall by the elevator, there is a
: raised number 5. Under that is the number 5 in braille. That raised
: number would mean nothing to someone who has never seen the number 5
: in print. I am presuming it's there for people who lost their sight.
: But the braille 5 and the printed 5 are equally valid representations of
: the concept of 5.
: Certainly the printed symbol 5 would be recognized by more people even
: so, they are equally valid representations of the concept of the number 5.
:
: A graph is just like that. A graph is not the actual data, it's a
: symbolic representation of the data. Any decent instructor would know
: that.  Yet, all too often on this list, we hear of instructors saying
: that math is too visual by nature for a blind student to grasp.  It's
: ridiculous.
:
: There is absolutely nothing in mathematics that is innately visual.
: In fact, the less you rely on the symbolic representations of the
: concepts, the better off you are. It's impossible to communicate
: mathematical concepts without symbols -- words, print, or braill --
: these are all symbols. But when you are working on the concepts in
: your own mind, the symbols can only get in the way. If adequate tools
: existed for 3D graphics,  a blind student might very well be better at
: it than a sighted student who might be locked into this inadequate
: perspective drawing concept.

: Dear all,
:
: I'd like to bring to everyone's attention a project to advance browser
: and
: e-reader support for MathML.  The project description itself is very
: detailed, and explicitly mentions the issue of accessibility in the
: motivation section.
:
: The person behind this project is Fr?d?ric Wang.  He is one of the
: people
: who has worked hard on MathML support in browser technology over the
: last
: few years, so is best placed to know what the issues are and what the
: next
: stage in development should be.  So if anyone is going to improved
: matters,
: he's the best choice.
:
: He's looking for funding so that he can spend some time concentrating on
: MathML development and the website is on a crowd-funding site where
: people
: can contribute.  The actual amount that he is trying to raise is not
: actually all that much, particularly given the wide-ranging benefits
: that
: could follow from this.
:
: I hope that all of you will consider supporting this project, and that
: some
: of you will actually do so.
