Glad you liked it. I was hoping someone on this list would have
personal recollections of this time and the tech available. Neat how
there was braille output as far back as the 50's. It's a shame that
that stuff is stil as expensive as it is. Perhaps, some day, as
happened with speech technology, blind people will see the price of a
braille display drop to something affordable as in, under a thousand
dollars? Same for a braille printer/embosser. I am enormously
concerned at how many of the blind kids I have met recently have poor
braille reading skils and don't really seem to care that they are
bordering on illiteracy. Having something or someone read to you is
not the same as direct input from a written document to your mind
without an intermediary. In this age of electronic texts, you would
think that braille would explode in popularity since you no longer
have to fill a room with tomes of the stuff.
