My Braille Toolbox Part 3: The Refreshable Braille Display

(This is Part Three of a Series. Here’s Part One and Part Two)

Ok, we’re skipping a few historical developments here, but this is my beautiful new Braille display, the VarioUltra 20, by BAUM.

The current generation of Braille displays like the VarioUltra combine the functionality of two earlier pieces of technology, the Braille notetaker and the refreshable braille display. They can function as either independent PDAs or as displays for a phone or computer.

The Hardware

The display portion is a single line containing, in this case, 20 Braille cells. There is also a VarioUltra 40, with 40 cells, and other displays range from 14 to 80 cells in length.

These things are truly mechanical marvels. The tiny nylon pins that make the Braille dots are only spaced 2.2 mm apart, and they must all be able to raise and lower independently. Each of the 160 dots on this display is connected to its own lever, which is raised up and down by a crystal that expands under electrical current and contracts when it is removed. They refresh in a fraction of a second—much less than the time that it takes to move your finger from the end of the line back to the beginning. And though they be small, they must be reliable and durable enough to be read hundreds of thousands of times.

The interface is entirely tactile, and the device is simply rife with buttons to navigate menus and files, enter and edit text, and manage physical and wireless connections.

At the top of the unit, there is an eight-key keyboard that is analogous to the six-key keyboard on the Perkins Brailler. Each key corresponds to one dot. Below that is the row of  Braille cells, each of which has a small button above it which are used for cursor routing and text manipulations. On either side of the braille display are three buttons used to navigate whatever text, file, or website you are reading. The bottommost row contains a little joystick they call a NaviStick, used to navigate the operating system, four system keys, and two space bars.


In independent notetaker mode, the VarioUltra has its own OS with a suite of productivity apps: a text reader and word processor, PDF viewer, spreadsheet viewer, calculator, etc.  

I can store files on there, from notes and handouts to whole books. It’s finally going to make Braille portable for me in a real and useful way. I mean, if you wanted to take a book to the park or coffeeshop to read, what would you rather carry?

When it’s hooked up to an iPhone, I can use it to read my email, articles, websites, facebook, twitter, and any other accessible material that’s available. 

Since this is my first Braille display, I anticipate a steep learning curve. To be honest, i haven’t even turned it on yet. This isn’t the intuitive, easy to pick up and start using technology we’ve gotten so used to. It’s the kind of technology where you read all the documentation before you even get started, and it still takes a while to get up to speed. With the crazy week i had, I just haven’t had that kind of time. That’s what the next few days are for.

I’m excited to get to know this device. I’m excited to carry Braille with me, to be able to read and work quietly again, and to get better and faster at reading Braille because I’m using it more and using it more seriously. I’ll keep you posted on how it goes!
