[BlindMath] Any Affordable Tactile displays to analyze graphs and charts

[Brandon Keith Biggs]

Hello Rejin,
That is the least expensive multiline tactile display. If you want to work
on inventing a less expensive multiline tactile display, there is
definitely a very low level of competition and high level of need!
You may want to check out Sonification tools:
http://sonify.psych.gatech.edu/research/sonification_sandbox/
Or the web version:

or
https://workspace.google.com/marketplace/app/audiographs/1078303178825
or
http://support.sas.com/software/products/graphics-accelerator/

These have a significantly smaller price tag, and get the job done for the
most part.
If you really want tactile graphics, then I would recommend one of the
swell paper machines:

or an inexpensive tactile embosser:

Hope this helps!
Thanks,
