OCR, or Optical Character Recognition, is the process of turning an immages into
understandable language characters. Just like your brain does if you can see
with your eyes, these programs have to learn what new characters are and they
usually make a few mistakes if the immages is smuged, not from a language they
recognize,, or not a symbol they recognize, Consumer OCR, can't understanding
handwriting and has trouble with certain types of high gloss papper. A good ocr
program is OmnyPage pro or if someone else is purchasing it for you and you are
not comfortable with Windows, Openbook. Openbook uses the numpad for all the
scanning functions and automatically scans and reads the pages using your
synthesiser. OmnyPage can be configured so you can use a wordProcessor open up
a blank document, and choose an option from the file-Menu which is called
something like aquire text or scann immage.Aditionally, with any OCR program you
may scann immages and read later after saving to a file, scann the immages at
once and perform OCR at a later time on all of them, or scann the immages and
not perform OCR. You may choose to leave tables formating and graphics in the
document or remove them from the scanned and recognized page. You will have to
modify the scanner and OCR software settings for it to perform with differing
fonts, papertype, formating etc. Good OCR products allow you to modify
contrast, have automatic orientation(place the page upsidedown and read it
writesideup), and change the brightness for reading darker or lighter text.
They may also have a proofread function and a training file where you can teach
it what certain immages are. However, I don't see how that is usable by us
blind folks. Any scanner will work some may work better then others. Not every
OCR product will work well. Avoid paperport at all costs because the interface
is shere crap and that's not just an opinion. The Visioneer or HP scanners
which are frequently bundled with this junky stuff work fine using any ocr
product. Good luck
