[BlindMath] Scanning braille for sight reading

[George Bell]

Hi John,

Scanning embossed braille is not an easy task.  Indeed there was once a
program called "OBR" (Optical Braille Recognition).  But even that required
that specific makes and models of scanner be used, which allowed control of
lighting during the scan.

You instructor should know this.

Do I get the impression you are using a Perkins type braille writer as
opposed to say 6 key entry into PC braille software such as Duxbury?

George

I'm taking a braille class through Hadley School for the Blind. I am trying
to submit my homework assignments as scanned images of braille pages for the
instructor to sight-read. The instructor asked me to scan them as photos but
I don't know what that means. Does anybody have experience scanning in
braille and can tell me the best format, mode, and dpi settings? I sent my
instructor tif line-art at 300 dpi which works well for OCR but that didn't
work for sight-reading braille.
