[Blindmath] Multi-Line Braille Display

Thu Jun 12 14:38:40 UTC 2014

I have seen pin art which is about a thousand pins that are set to slide parallel to one another that you place your hand or object under to creat a 3d projection in pins;
I have seen a braille strip that uses a series of small matrices of pins to form braille letres and numbers;
And I have seen diagrams and text produced by the tiger brailler that uses a 200 by 200 matrix of braille dots of varying height;
In my minds eye, I see the future of v I  tech.

I would think 5 lines would be a good starting point.  That would give you enough to see 3 or 4 lines previously so you can check your work ... review a proof ... etc.  Of course we KNOW we will NEVER (and I capitalize those for sarcasm) need more than that.  After all, let's quote the master Bill Gates who made the famous statement ... "who would ever need more than 640K of memory on their computer?".  HELLO!!!  Now we have machines with 16 GB of memory on the main board.  Conclusion .. never say never.  But back to the Braille display, if cost was driven down, 25 lines might not be desirable due to the size of the device, but maybe you might want 5 or 10.

I'm waiting to see what Tactus Technologies comes up with.  They have figured out how to deform a tablet's surface and make "bumps" appear on the surface.  They do it by applying current to the surface and it makes buttons appear.  I wrote to them and they said that Braille applications are on their radar, so we can only hope.  Perhaps there are other technologies out there that I'm not aware of.  This solution, anyway, means that the deformable material could be installed on every device manufactured for sighted or blind consumer alike ... just like building the accessibilty into the iPhone and distributing it to everyone.  Those that don't need it don't turn it on.  But it's there for those that do need it.  Keeps the cost distributed across all users.  Great strategy.

Let's hope it comes to pass.  Even if multi-line displays didn't come to pass, adopting a strategy that could drive the price down would mean that more blind people could get a Braille display and have tactile access to math or science (and other) texts.

It would also be useful for blind web developers in allowing them to get a better picture of how the web page is layed out.
