There's been a lot of talk about multiline braille displays, but one group has
created a set of working units that are in the hands of testers. Dubbed the
Canute, the display was demonstrated by Bristol Braille
Technology,<http://bristolbraille.co.uk/> a UK-Based nonprofit and hackspace
which recently created the prototype. The display includes 4 lines of text
containing 28 cells per line and costs 440 pounds, or roughly $686 U.S. dollars
as of the time of this post. Their website hints at a possible 8-line version
as well. It uses off-the-shelf components and is powered by a Raspberry Pie, an
inexpensive ultraportable computer often used by tinkerers. The software
powering the display is also open-source. Check out the press release below to
learn more. Thanks to Dave Williams for the tip.

Canute: Press Release

19th of May, 2015

World's first multiline Braille ebook reader demonstrated in Bristol and London

Bristol Braille Technology CIC, a not-for-profit company operating out of the
Bristol Hackspace, has completed the first feature complete prototype of
Canute. Canute will be
the world's first multiline refreshable Braille ebook reader
, which will cost less than a Braille typewriter and a fraction of the price of
existing single line displays.

It is intended that Canute will help reverse the decline in Braille literacy by
bringing digital Braille within financial reach of the average user for the
first time.

Canute, a stand-alone refreshable Braille ebook reader for 440, being rolled
out to testers over June

On Monday the 18th of May Canute Mk6 was demonstrated to the Bristol Braillists
blind advocacy group in the Pervasive Media Studio, who were able to choose
between and read a dozen novels that had been preloaded onto the machine.

On Tuesday the 19th Canute Mk6 was demonstrated again to the Information
Technologists company in Stationers' Hall. During the meeting BBT also
demonstrated Canute's ability to double up as an embosser, which means one can
emboss notes, shopping lists, recipes or letters directly off Canute's surface.

On both occasions the feedback was very positive and the device was deemed
ready to be tested by users in their own homes. Over June BBT will therefore be
working with the Bristol and Reading Braillists groups to ensure Canute units
are tested by dozens of blind users.

Emulator and software Open Sourced on GitHub - Braillists ready to expand

The Canute uses radically different internal mechanisms from the prohibitively
expensive existing Braille displays, which allows it to have the unique format
of 28 characters per line over 4 lines.

It uses off the shelf motors and plastic components from laser cutters. It runs
off Open Sourced ebook software that can be freely changed so users can add
their own functionality, adapt the user interface to their tastes.

There are already blind users and sighted engineers from around the world who
have expressed an interest in adapting it to various different use cases and



It's something phenomenal. I'm already in love with this, and I'm not really a
Braille person. I gave up Braille many years ago... but this would definitely
intrigue me... I'm completely blown away by this. Andre Louis, a blind
musician and broadcaster, at Stationers' Hall, see Periscope broadcast:


There are many wonderful ways digital technology can open the world up to those
with visual impairments and this can be balanced by opportunities to master
written culture, whether as readers or writers. We are proud to be supporting
Canute, which is at the forefront of efforts to bring Braille, and therefore
literacy for blind people, into the 21st century. Vicki Hearn, Director
of Nominet Trust

I am delighted that the Innovation 4 Growth programme has enabled Bristol
Braille to realise its research and development goals, and to evolve an
innovative concept into a product that is ready for user testing. Tracey
John, University of the West of England Head of Business, Research and
Professional Development

To the editors:

For many blind people Braille
literacy. Braille teaching and usage has been falling for decades and are now
in danger of entering terminal decline. Technical stagnation has left a
majority of blind people without the means to become literate or exercise their
literacy. Canute is intended to help reverse this decline by being multiline
and radically affordable.

Bristol Braille Technology was founded in 2011 by Ed Rogers to continue a
project he had been working on since 2008. The Canute project began in October
2012. Its team is composed of volunteers and those working at voluntary

Bristol Braille Technology has committed to creating devices that can be
manufactured and repaired anywhere in the world, to Open Sourcing as much of
its work as possible, and to allowing individuals to build their own devices
according to their own needs from those sources. We are protecting Canute's IP
with licences which will allow us to ensure that all improvements to the design
must be fed back to the community.

Canute is controlled from an internal Raspberry Pi computer running Raspbian
Linux. Computer Aided Design is done in the Open Source OpenSCAD programme,
which is entirely textual and will eventually be editable by blind designers
using the Canute itself.

The Braillists group was co-founded by Scott Wood, Senior Technology
Co-ordinator at Action for Blind People, Paul Sullivan, Access Officer at
M-Shed and Steph Tyszka, a social entrepreneur associated with BBT. It has over
sixty members from around the UK.

The Canute has been developed with funding from
iNet Microelectronics, iNet Biomedical, The School for Social Entrepreneurs,
Blatchington Court Trust, The Product Development Centre, The Information
Technologists' Company and The Engineers' Innovation Network.

The Canute Mk6 specifically was funded by;

Innovation 4 Growth

The University is committed to supporting enterprise and economic development
in the Bristol city-region and right across the South West, with health
solutions and assisted living being a particular area of focus. This is an
excellent example of that commitment translating into real support for
promising regional businesses. We wish Bristol Braille every success with the
trials and look forward to supporting other SMEs when the next round of
Innovation 4 Growth funding launches later this year. Tracey John
