Multi line braille display (self.Blind)
submitted by CloudsOfMagellan
Does anyone know of a full screen braille display
I've only only ever had a single line one and the best I can find online seems to only show 9 lines at a time

There's nothing like you're probably dreaming of, yet. Single-line displays have 8 dots per cell and up to 80 cells wide, and cost anywhere from $500 for the cheapest 20-cell display to $10,000 for the most expensive 80-cell display.
Given those prices, multi-line displays have to make compromises.
The Bristol Braille Canute is probably the closest thing to a multi-line display that actually works, is actually for sale, and really has multiple lines. Maybe that's the one you saw, it's 9 lines of 40 cells, with 6 dots per cell. Do you realize just how ridiculously large that is, though? 9 lines of braille makes for a pretty large device already. If you wanted 25 lines it literally wouldn't fit on your desk.
Anyway, the main tradeoff the Canute besides 6 dots is that it's slow to refresh. You can't use it for real-time text editing really, it's good for reading books. The price is good for how many cells you get though, under $2000.
DOT Inc is working on a tablet, I saw a demo at CSUN. Definitely not finished and not ready to buy, and it's not clear what sort of software it will have.
The Graphiti is interesting, it's a 2-D grid of dots that can be used to make shapes and images. Pretty cool and comes with some nice software, but the dots aren't small enough to make actual braille.
That's the state of things today as far as I know.

It's not intended for reading, and it looks like it won't be available for a while due to a dispute between the companies involved.

hello I am developing a new way to read braille that could support a full page.
It involves using virtual cells for orientation and a physical cell for braille output.
I am working on the portotype and it is open source.
the problem is that no screen reader currently has multi-line support, it only supports one line and a maximum of 200 characters.
To develop a multiline braille display, it is necessary to have a screen reader that can send well-formatted information

Can you explain this further please?
As for having screen readers sending multiple lines could you have it request multiple lines one after the other mimicking a traditional display but then show them all at once?

The problem with doing that is that you will certainly see several lines but they do not guarantee that those lines are in their correct position, it is simply one line after another but for example if we have dynamic lines that change when clicking on a name that line would be loaded again at the end and not in its corresponding site
The problem that I cannot understand well, you explain me because I do not speak English, I am using Google translator, my language is Spanish.

Couldn't you refresh everything each time you get an update from the screen reader?
ilcergio 1 points 1y ago
I can update all the lines that I have but not all the pages have the same size so yes I have 20 lines and the page has 30 lines only the first time it is 20 lines but the second time I will see the last 10 lines and the first 10. Also, if the line has 200 characters and my line only has 80, I will be showing in several lines what is really in a single line. The only way to fix that is for the screen reader to recognize the line and I just sent the information for one line on that line the rest is not going to work.

Hi, @CloudsOfMagellan,
My name is Liam and I work for Bristol Braille Technology, a social enterprise based in Bristol in the UK developing Canute 360, the world's first multi-line Braille e-reader.
As @dmazzoni mentioned, Canute 360 features a nine-line, 360 cell display. It features six dot Braille and is a standalone desktop reader. You can pre-order a Canute 360 from Techno-Vision systems for £1,895 ex-vat at: $1. We can ship worldwide.
​
If you do have any other questions, feel free to email me at $1 and I will be happy to help you out!

The Brailliant B 80 has an 80 character count rather than the standard 40 and uses thumb keys with no top buttons.
The downside is this device is around 8000 dollars.
