Non-linear Braille reader?

On the Media had a very interesting interview about the drop in Braille usage from 50% of the blind to merely 10%. It gave me an idea.

Would it be helpful if the blind had a device built into computers, or attachable via USB or whatever, that had eight fingerpads (or maybe ten, with the thumb ones along the bottom) each of which could form a Braille character? Instead of running their fingers across a strip of Braille characters, the computer would create a burst of 8 (or 10) characters simultaneously, on a timed tick the speed of which the user could of course control. So, instead of reading by getting the letters one at a time, you would get them 8 (or 10) at a time. Might this speed up the reading of Braille?

It seems closer to how we actually read: In word-sized clumps, not letter by letter. So, to provide words as Gestalts, this finger-tip Braille display could in each tick present as many words as can be presented in 8 characters; words of more than 8 characters would be presented in as many ticks as it takes, with perhaps a slight change in tempo or an auditory cue to let the user know that the word is not yet complete. But, all of that is just software.

I did a quick patent search at Google Patent and didn’t immediately find anything. Is that because this is not a good idea? Or am I just bad at searching for patents?

Braille question

On the Canadian train I was on this morning, the signs in the bathroom were in English, French and Braille. Nice. But I actually don’t understand. How do the blind know that there’s a sign there in the first place? Are they supposed to run their hands over the walls of the bathroom looking for the “Please be courteous and leave this bathroom clean” sign? Or are the Braille signs for the partially sighted?
