[nabs-l] [nfbcs] new open source Braille translation software for the blind

[Steve Jacobson]

Joe,

The fact that I got excited when I saw the subject and then disappointed when I didn't find an announcement of an 
open source translation package already available probably says it all.  While I understand very much the complexity of 
braille translation and why translators cost so much, it is hard to swallow spending what one spends for a braill printer 
only to find one usually has to spend another $500 to use it.  There are exceptions of course.

As a person somewhat familiar with the development and evolution of NFBTRANS, I recognize that we need something 
more than NFBTRANS offers.  Be careful, though, not to under-estimate the difficulty of developing a good translator.  
You would not believe the number of strange things we had to debug and correct in NFBTRANS over the years.  Some 
problems don't make themselve apparent until someone runs into a particular situation that uncovers the problem.  
Translating a long document can really give a translator a workout and expose shortcomings in a way that doesn't 
happen with other software.  A translator really has to be solid for people to count on it.

If a better program than NFBTRANS becomes available, I would be the first to loudly applaud.  This is an old program 
that has already served people well.  Please consider two things.  First, I think there are some good possibilities for 
improving NFBTRANS without re-inventing translation.  There is a lot of room for a more complete Windows interface 
than has been developed with WINTRANS.  WINTRANS is an extremely good effort but development has stopped.  In 
addition, I think that the possibility of adding the ability to get formatting from Word documents would add a lot of 
usefulness to NFBTRANS.  These would both be projects that could be manageable without having to start from 
scratch.  NFBTRANS has already been compiled under LINUX and UNIX, so the possibility of adding some interfaces 
there exists as well.  

As stated above, NFBTRANS is old code.  If you are really up to doing a translator from scratch, please consider looking 
at the NFBTRANS source code, not as a model, but to see what kinds of problems that have been encountered and 
solved.  Also, look at the NFBTRANS table to get a clear feeling of how many different things have to be considered to 
do good translation.  Maybe you have already done something like this, but I can only say that I am a programmer and 
was still surprised at all of the different types of rules that had to be developed to do good grade II translation.  

The fact that you are interested is exciting.  Please let us know what you decide to do and if any of us can be of help.  

Best regards,

Steve Jacobson
