[BlindMath] Advice on handling the visual side of mathematics

[rjaquiss at earthlink.net]

Hello:

     The American Printing House for the Blind (APH) sells a device called the Draftsman. The Draftsman allows a user to draw on special plastic film that forms a raised line. Accessories include a ruler, protractor etc. It is also possible to copy a printed drawing to SwellTouch paper and then process the SwellTouch paper with a SwellForm machine from American Thermoform.
The image will be raised. ViewPlus Technologies sells a variety of embossers that produce raised line graphics.
A low cost way is to use WikiSticks which stick to paper. The WikiSticks are somewhat reusable.
Hope this helps.

Regards,
Robert

Hi Aman. While drawing figures on our own is not a possibility as of yet I suppose but to visualize them is possible to some extent. There is a drawing board with surface like that of a window net. When a figure is drawn by placing it on the surface of that space, reverse impression of the figure comes on the opposite side of the paper. Then it is possible to feel that figure. I am not sure about the name of the drawing board but you can try it out by using window net or any kind of rough surface like that. Additionally, apps like be my eyes can also be used in this case. You can share a picture of the diagram (like graph of sine curve) with be my eyes and get it explained.
Hope that helps
