[BlindMath] Transitioning from Completely Visual Math to Less Visual Math

Tue Apr 4 03:55:30 UTC 2017

This hyperbraille device exists - I have seen it at the Sight City show in Frankfurt. However if it is for sale, that does seem to be a deep secret. I have been told that the next model will be less expensive, possibly costing less than US$100,000. It is a bit smaller than an 8.5x11 paper and has resolution of approximately 0.10 inch - which is okay for braille though with more than the usual inter-cell spacing. I do not know anything about supporting software. My advice is not to hold your breath waiting for it to come to market. At best it will never be something that the average blind user can afford. I do not believe that the technology can be scaled to be inexpensive at any volume.

Hi,

here is a Link to "Hyperbraille":

I hope it helps

Kind regards
