I knew from watching my papa that I had to make the hole right in the middle of the strap. I looked very closely, placing the point of the awl just so, and I pushed. The leather was very tough, so I pushed and pushed and, mes amis, I do not know how it happened.
I poked my eye; it hurt. Shrugging in resignation Infection came, taking both my eyes. In those days we did not have the medicines of today, and I am lucky I did not die.
Louis Braille - Educator - Biography
Though my parents did their best for me, the only blind people they had ever seen were beggars on the streets. Placing his hand over his heart with much emotion Mes amis, God love them. They believed that, if only I had a good education, I might make something of my life. So at age seven I was enrolled in the village school.
I did well for not being able to read and write. Pausing for emphasis But, Messieurs et Mesdames, I ask you, what is an education without literacy? Mais oui, my parents wanted more. They had heard of a school in Paris, the Royal Institute for Blind Youth, where a blind youth could learn a trade. So at ten I left my home and family to go to the big city. I will not tell you the details of life in that damp and drafty old building with steep, winding staircases and long, narrow hallways, where the slightest noise echoed.
And, mon Dieu, the food!
The Evolution of Braille: Recognizing Louis Braille on His Birthday
This banquet food making a broad, two-armed gesture meant to include his surroundings in comparison is a feast. But that school had one advantage beyond price, books that could be read with the fingers. The print was raised. One traced each sentence, letter by letter, word by word. In many cultures well-meaning people have tried using such a system of embossing the language. A shrug Messieurs et Mesdames, though the blind can read the words, the system is very slow.
When I was twelve--for those of you who care for such things, it was we learned of a new raised system of reading. A soldier came to our school--I will never forget him, Captain Charles Barbier. The good captain thought his system might prove useful to the blind. Mes amis, you will not be surprised to hear that, like other boys and girls would be, we were fascinated by the raised dots and dashes of this new code.
Charles Barbier invents 'night writing'
Alas, there was no punctuation or capitalization, and the symbols were not letters but sounds. All too soon everyone lost interest in night writing. However, I could not stop thinking about the code and running my fingers over and over the dots, wondering what could be made of this idea; I knew something was there. Then success! Pausing reflectively Messieurs et Mesdames, those of you who know history know that my raised-dot system was not accepted with open arms.
No, not even by my teachers, not until After a tiny pause, brightening However, the blind of the world did eventually receive the gift of literacy, the ability to read and write independently. I am proud to say that others have taken my French system of reading text, made it fit their languages, and developed additional codes, such as the one for mathematics. Now the blind in all cultures can be literate. It is time to look at the present and the future of literacy for the blind in America.
Pausing to lift a copy of the Braille agenda for the evening I am holding up tonight's Braille agenda. Pausing for the shouts of No! Let me review my research about where Braille literacy has been, where it is today, and where it must be in the future. Cocking his head and raising an eyebrow You Americans do know that Braille was not your only touch system for writing? You too had your hand tracing an imaginary curve to illustrate raised print writing, then tracing a block letter in the air Roman letters. Messieurs et Mesdames, such writing is pretty to look at, easy for the sighted to read, but too slow to read with a finger; and one cannot write it by hand.
Then there were the dot systems--you have had several. By the s and 50s many blind adults in rehabilitation were being taught Braille and 50 to 60 percent of blind children were learning to read and write Braille.
A Short History of Braille
Like me, the majority of these children lived in the schools for the blind, where blindness skills were deemed important. And oui, blind children learned to read at the same time as sighted children. As I was saying counting on his fingers Braille readers were reading one-, two-, three-hundred words a minute, and more--blind people reading as fast as their sighted brothers and sisters.
Though, mes amis, shrugging in resignation back then Braille books were not as common as print; Braille readers of the last century were not like the fortunate Braille readers of today. Think of it, reading without paper! For me, as well as for thousands of others, reading Braille has the same wonderful impact that reading the printed word has for a sighted person. I would have loved to watch Louis Braille when he began punching out the first dots with his newly-invented slate and stylus.
We still use and teach this method of writing Braille today, which punches out one dot at a time. MBraille and BrailleTouch. Newly blinded adults are drawn to refreshable Braille displays which they can connect to their computers or phones, or a Braille electronic notetaker such as the Apex, BrailleNote Touch, and BrailleSense. I find that my students enjoy reading one single continuous line of a Braille display, as following this straight line avoids reading lines on paper which are written very closely together.
Going hand-in-hand with technological advances in the new UEB United English Braille code which globally unites all those who read English-speaking Braille. As pins are raised and lowered below a static resting finger, the missing lateral movements lead to very low reading rates and complete loss of spatial orientation along the line of text.
To overcome the page or line orientation problem, virtual Braille-Displays have been designed, where one [ 20 ] or few [ 23 ] Braille-cells can be moved along a virtual line or across a virtual page showing the contents of the location thus addressed. Left: Pantobraille [ 20 ]; centre: Braille on a carriage [ 23 ]; Right: lateral stimulation [ 24 ].
Starting in with a basic idea for a robust, pocket-sized and reasonably priced Braille-Display, two students from the TU Wien were successful in proving the concept in their theses [ 25 , 26 ] and in building an enlarged 2. Since then, the concept has been refined and pre-tested by blind users with simple mock-ups. A national patent [ 27 ] was granted, international applications are pending. Moreover, it should become an alternative for those applications where existing technology is too bulky, too heavy, too delicate or too expensive.
The BrailleRing has a huge potential to significantly increase the mobility of Braille-Displays. The design allows building very compact devices where the line length is completely defined by the user. A later envisaged motor drive could provide even endless lines. The concept will also increase robustness, making the display more suitable for outdoor activities where humidity, sand and dust could be an issue. If built in such a way that the rotating ring can be changed easily, the user would be able to clean the device on his or her own. Different types of rings can be provided according to specific user preferences e.
It should be possible to build a device with much lower production and service costs than conventional piezo-electric Braille-Displays. Therefore, the BrailleRing should also be ideally suited for a market in developing countries. Presently March , several mock-ups and simulation devices in real size exist or are under development. These aim to understand the reading experience inside a ring and demonstrate the final size of the device mobile.
As the Braille-dots are not formed by moving pins, the BrailleRing will offer much more degrees of freedom in haptic Braille representation. We intend to invest significant efforts to optimize the tactile user experience before the final design. Another development goal for the second quarter of will be the search for optimized actuators that are able to turn the cuboids reliably independent of reading speed and direction while at the same time, minimizing the power consumption, which is crucial for a mobile device.
While the discovery of the mechanism with disruptive potential was serendipitous, a user-centric approach is what steers further development. Before IP protection, user involvement was on a nondisclosure basis, so only one single blind Braille expert was included from the outset. This was changed after the patent was granted and user studies started immediately.

They can be described in two major phases:. First, through local news reports about the invention, a call for user-participation triggered 25 curious responses by blind people. Around half of them were invited to semi-structured interviews conducted in-person. Simple mockups were used to explore the new way of reading and the concept of a truly mobile Braille-Display. In the second phase, the list of candidates for user studies grew to 50 by word-of-mouth.
Here the user trials will focus on usability, ergonomics and especially on tests with different Braille pattern sizes and dimensions. This is crucial, as some first trial- users mentioned that the felt character to character distance is smaller when read from a concave surface. Afterwards, user studies with an adapted mockup will follow where reading speed and error rate compared to conventional flat Braille-Displays will be measured quantitatively.

Solenoids either need a lot of space and energy to produce sufficient forces or will, when miniaturized to fit beneath the footprint of a single Braille-dot, only provide low forces making latching mechanisms necessary Fig. Open image in new window.
To avoid the necessity for any moving parts pins, actuators several researchers experimented with direct stimulation of the neural tissue of the fingertip. A major drawback of mechanical solutions is the number of delicate components needed. In piezo-electric Braille-Displays, each pin has its own actuator, adding up to a whopping actuators in a standard 8-dot display with 40 characters.
