[BlindMath] Scanning braille for sight reading

[Larry Skutchan]

It sounds like the instructor simply desires a photo of the braille, so he can look at it to judge its accuracy.
If you have a smartphone, one effective way to capture an accurate image is taking a picture 
The hardest part of getting a good picture is getting the whole page in view, and KNFB reader has the absolute best tool for alignment and centering with its Field of View Report. 
You don't need the OCR capabilities of KNFB reader for this task, but use the alignment tool, snap a picture, then get that picture somewhere where it is easy to send, like Dropbox.

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.
