[Blindmath] Reading graphs and diagrams with sound

[Louis Maher]

Hello Ruchi,

There is a company, named Sensational Books, which makes a $30 drawing
tablet.  You can take a standard 8.5 X 11 inch sheet of paper, and sketch
drawings, with a ballpoint pen, that a totally blind person can feel.  You
just hold the pin at a 45 degree angle to the vertical, and almost instantly
you have a sketch that a blind individual can feel.

People learn through simple diagrams, and this is the quickest, simplest,
and cheapest tool that I have found.

Dear all, 

 

I was wondering what is the best way to read a graph with sound? Was looking
at the following products - seeingwithsound voice, viewplus AGC and NASA
mathtrax. To give a little introduction, I am a mother of a 9 year old blind
kid and am looking at ways in which I can teach him geometry - constructing
diagrams and reading them as well. Also, was thinking if there are any tools
for analytical parts - bar graphs, pie charts, line graphs and the like. I
know there a lot of tactile tools available, but the kind of experiential
independent learning that computer based learning methods have is
incomparable.

 

Eager to hear from you all.

 

Thanks and have a splendid day!!!

Ruchi
