“Braille is on the verge of a global catastrophe ... My broad, conceptual proposal for saving Braille is to democratize it, to take Braille out of the hands of professionals & put it into the hands of the people ... Slash the cost of refreshable Braille.”
— Kevin Carey, Chairman of the Royal National Institute of Blind People, speaking generally about the situation in July 2012
Bristol Braille will slash the cost of Braille literacy with the world's first commercially viable multiline refreshable Braille. Canute will be an eight line Braille e-book reader for blind people priced £300–440; a fraction of the cost of existing single line displays.
And we are proud to announce our newest invention, Midas, which, at a cost of less than £100, will turn any surface into a page of refreshable Braille.
So far we have been contacted by over a hundred Braillists around the world, each of whom has expressed a strong desire to both buy & help test a be-reader from us. We are committed to creating devices reflecting their needs in form & function which they will be proud to own.
What follows is a small selection of quotes from these Braillists;
“Braille frees the mind & the spirit” — ‘TAS’, May, 2012
“I had the opportunity this year to teach four people who have recently lost their sight to read Braille ... Truly an amazing thing to watch these individuals who thought they'd never read again, reading, truly reading, not listening, not hearing a synthetic voice ... If there could be a Braille display which would serve their needs, it would be a miracle.”
— ‘Ann P.’, May 2012
“My biggest frustration is the cost of Braille displays. The only reason I have mine to use is because of my job at the university. Were I to leave this job, it would be very difficult, if not impossible, to get one of my own. As someone who trains others in the use of assistive technology, I can attest to the fact that many of the people I work with would love to have access to a Braille display, but cannot due to their cost. ”
— ‘Keith’, May 2012
“I cannot find the words to say how great the work is that you & your colleagues are doing to make a Braille unit that it is accessible to everyone ... It will make such a huge difference to so many, many people.”
— Gaela Benn, October 2012
“First off, as someone who has been blind all my life, let me say that I fully support your goal of cheap Braille. I hate to see Braille literacy plummeting ... anything to reverse that troubling trend is wonderful.”
— Alex Hall, January 2013
“I have been a Braille reader since 4 years of age. I am now 23. Unfortunately, I must say that I do a lot less Braille reading these days. This is because I do not have access to a working Braille display. & I find paper braille to be cumbersome to load around. Why read my paper Braille books when I have loads of them on my computer thanks to Bookshare?”
— ‘Rose’, March 2013
“ I now volunteer at a place where I answer phones, & I use my laptop muted, with braille, to take notes on calls ... At the same time I started coding ... I find using braille for both these tasks pretty invaluable. My main problem with the displays on the market now is their price. They are horribly expensive, & I certainly couldn't afford to replace mine.”
— Chris Norman, May 2013
By developing revolutionary new Braille technologies that will retail for hundreds rather than thousands of pounds, we at Bristol Braille Technology are attempting to transform the lives of blind people around the world, providing access to reading matter which the vast majority do not currently have. This absence seriously restricts the number of opportunities to become literate, even damaging the value of literacy itself.
Our ultimate goal is to have refreshable Braille that is affordable for every blind child & adult, anywhere in the world, & to see a measurable improvement in literacy as a result.
Bristol Braille Technology is a not-for-profit organisation* dedicated to serving blind communities through invention & the provision of Braille devices. The great majority of our work to date has been done on a voluntary or part-voluntary basis. We operate out of the Bristol Hackspace, which is a part of the international ‘Maker Movement’ of co-operative workshops.
Existing single line Braille displays are pretty good, but far too expensive for most people, costing in excess of £1,400. We aim to produce new classes of devices for as little as £100–440 .
Piezoelectric motors which individually drive each pin in the machines are the reason for the high prices. We will get around this by using entirely different technical solutions.
Our approach to the problem has always been the same.
There may, indeed we hope their will, at some point be a marvelous new material that can transform perfectly into Braille. But until that day comes, & until it becomes affordable, there has to be a ‘low-tech’ solution that does not require a million dollar lab to implement. This is not low-tech for the sake of it; avoiding huge research overheads reduces the final price for Braillists, increasing the number & geographical range of people who can benefit.
We therefore concentrate on two mechanical principles. Firstly, there must be be a disconnect between the pins themselves & the cost. In other words, the pins must be cheap & increasing their number should not significantly increase the cost of the whole unit. Secondly, we use off-the-shelf components whereever possible.**
We create be-book readers that can be manufactured & repaired in ordinary workshops all around the world. The software we're using, OpenSCAD, is entirely textual & editable by Braillists, meaning they'll be able understand the CAD process that went into their machines, or even design their own.
By operating in such a manner we shall create a class of machines equivalent to the common bicycle; uncomplicated & universally repairable designs, ubiquitous within blind communities for decades to come.
We are proud to have worked with, been funded by or otherwise supported by the following organisations. Listing are in order of association with Bristol Braille since 2008.

Our various projects have been on-going since early 2008. In the early years we investigated a number of different designs, including those based on continuous loops, ticker-tapes, dot-matrix printers & biometals.
Prior to the 6th of January 2011 this was a purely personal endeavour by Ed Rogers. Since then, & since our official formation as a Community Interest Company a month later, we have flourished into a small but active & committed team. You can read our news items from this period here.
In August 2011 we started development of the Quixote, based on the principle of slider-encoders & parallel actuation.
In September 2012 we looked into different design, which became the Canute one month later. This is now in parallel development as our all-new full-page be-book reader, Canute.
Sometime in Autumn 2013 we began investigating a very different device. In January 2014 this became the separate Midas project.
We operate as a collaborative Social Enterprise centred in Bristol, England. We are all either unpaid volunteers or on voluntary half-rates. Listings are in order of association with Bristol Braille since 2008.

After a period of incubation by Bristol Braille, Babel Technology CIC is continuing to develop Midas as a separate company.
Particular thanks must go to the redoubtable NK & endlessly patient Keith. Without the encouragement & criticism of these two men Bristol Braille Technology would never have reached the stage it is at now, or, indeed, have got anywhere at all.
Join us on the forums to ask questions, make suggestions, or propose & discuss concepts. Alternately you can reach us by post, pigeon, telegram, telephone, dead letter drop or e-mail.
We welcome expressions of interest from testers, potential customers, well-wishers & those interested in joining the development process. If you live in the Westcountry, are able travel to Bristol, or are associated with a Hackspace then we would be doubly interested.
We are currently looking for a variety of individuals who would be interested in testing our prototypes; most particularly Braillists of course, but also teachers & parents of would-be Braillists. Please do get in touch if this is could be you.
We're on track to demonstrate a four line Canute prototype on the 8th of September. However the project is due to run out of funds by the beginning of August. Even a small donation helps get Canute to manufacture by the end of 2015.
If would like to help us throw open the world of Braille literacy to people who would otherwise have to remain permanently outside it, then we are very grateful for all donations received at Bristol Braille. All donations will go towards the Canute project unless specified otherwise; we can alterately take donations specifically for Midas or to sustain the Bristol Braillists usergroup.
Besides Paypal ( see below ), we can accept cheques made out to Bristol Braille Technology CIC. We are happy to send out literature further describing our projects, or to answer specific questions in private prior to a donation.

Our newest refreshable Braille concept, begun in September of 2012, Canute is an attempt to build a full-page Braille e-book reader; or be-book reader. It will be an entirely new class of device to bring Braille to people who would otherwise be unable to afford anything other than massive, bulky hard copy Braille. It will be 28 cells by 8 lines, cost £300, and is neither related nor technically similar to either the Quixote or, so far as we are aware, any other published design.
“Printed books are plentiful & affordable, however, Braille books are presently scarce & expensive. A reliable, affordable, & universally useful electronic Braille book reader has eluded researchers & manufacturers for decades.”
— P. Duran, D. Gipson & L. Jenkins, Braille for the New Millennium, Jan 2000
Midas is a new product in development from Babel Technology CIC, in partnership with Bristol Braille Technology.
The Quixote was a project to compete with current Braille displays. It used a parallel slider-encoder mechanism to set Braille pins in either six or eight dot format with a series of ridged sliders.
In late 2012 the concept described in the Youtube video ( with descriptive voiceover ) was taken over by a third party. We are not at liberty to discuss their progress, so the video should be assumed to be out of date in many of its particulars.
Meanwhile while we at Bristol Braille Technology continue to see how we can take the basic idea of the slider-encoder & apply it to less conventional displays, we have moved on from active development of Quixote in order to prioritise Canute.
There is a discussion of the video on our forums.
We recommend the following as authoritative sources of information;
We are indebted to Ingrid Dijkers for donating the background image, & to Kroc Camen for creating the excellent Open Source NoNonsense Forum.
