#3it seems like making building an electronic braille display is an interesting side project.
i don't know, 30 units of display thingy that sized similar to mahjong tiles, two buttons to change them to "next line" and "prev line", and maybe a raspberry pi and one sdcard for each book maybe enough to build it?
of course the difficult part is the "display thingy". not sure if they have it in shenzhen.

you need fast refresh speed with pins which are steady under pressure while reading. Also, it should be packed so that you can have 6/8 pins to form a braille cell. the rest is a breeze.
personally, I think that braille is just not worth it for normal reading, but you can't do any stem without it because math is not linear like normal text and tts just sucks.

Have you looked at existing braille "displays"? There's a few models out there.

of course i know. the main point of my previous comment is building one as a side project.

#8Braille is an amazing invention. As a sighted person, my fingers can't differentiate the patterns at all but of course that would come with practice. I worked with a guy once who used a Braille terminal and he was just as fast as anyone else.
One thing I always wondered with Braille signage and the like - how do you know it is there to touch it? Is there some convention for placement?

Braille displays are pretty common, but awfully expensive. If your side project ends up costing less than $1000, you're on a good track. Most of them are in the $2000-$7000 range, with the exception of Orbit Reader 20 which is only $800 (although many online shops seem to be permanently out of stock, I don't know if it's really sold at that price).

I met a blind person studying computer science. I asked him why he used a speech synthesiser instead of a Braille display and he replied that he'd love to have a Braille display but they are far too expensive for a mere student.
(The sounds that emerged from his speech synthesiser didn't much resemble human speech but he was used to it and it was obviously quite a lot faster than normal human speech.)
