[nabs-l] Fw: Touchscreen Braille Writer

Sun Jan 6 23:20:38 UTC 2013

I'm surprised anyone feels comfortable typing on a touch screen. I'd not 
want to type in braille on a touch screen anyway; as Arielle said, it would 
be useless without speech anyway.
I don't see how you keep your place on the keys on a touch screen.

Hi,

Correct me if I'm wrong, but I don't think it's on the App Store
market yet.  If it is though I'd love to test it out.

I do agree with some things that were said, that the Braille OCR
project should be picked back up and that the reasons for stopping it
were bogus, but I'm excited to see what this App is.  I love how small
my BrailleSense On-Hand is, but if I, or any college student for that
matter, could just pack an IPad along with a braille display and have
the capability to go back and forth between writing in print and
braille that would be amazing.  Although it wouldn't fully eliminate
notetakers and laptops from the equasion, it would certainly make bags
a little lighter and have sort of a 2-in-1 feel.
