Bert Frees, Christophe Strobbe & Jan EngelenOdt2braille brings braille to your officePresented at Leipzig Braille 21.The AEGIS project seeks to determine whether 3rd generation access techniques will provide a more accessible, more exploitable and deeply embeddable approach in mainstream ICT (desktop, rich Internet and mobile applications). This approach is developed and explored with the Open Accessibility Framework (OAF) through which aspects of the design, development and deployment of accessible mainstream ICT are addressed. The OAF provides embedded and built-in accessibility solutions, as well as toolkits for developers, for “engraving” accessibility in existing and emerging mass-market ICT-based products, thus making accessibility open, plug and play, personalised and configurable, realistic and applicable in various contexts; AEGIS is placing users and their needs at the centre of all ICT developments. Based on a holistic UCD, AEGIS identifies user needs and interaction models for several user groups, (users with visual, hearing, motion, speech and cognitive impairments as well as application developers) and develops open source-based generalised accessibility support into mainstream ICT devices/applications: desktop, rich web applications, and Java-based mobile devices.All developments will be iteratively tested with a significant number of end users, developers and experts in 3 phases and 4 Pilot sites Europe wide (in Belgium, Spain, Sweden and the UK).The project includes strong industrial and end user participation (the participating industries are among the market leaders in the corresponding mainstream ICT markets). The project results’ uptake is promoted by strong standardisation activities, as well as the fact that much of the technology results will be either new open source applications or will be built into existing and already widely adopted open source ICT.Project number: 224348Project acronym: AEGISProject title: Open Accessibility Everywhere: Groundwork, Infrastructure, StandardsStarting date: 1 September 2008Duration: 42 MonthsAEGIS is an Integrated Project (IP) within the ICT programme of FP7http://www.aegis-project.eu/

OVERVIEW

odt2braille brings Braille to your Office
• Braille production = expensive, time-consuming• Typical workflow = multi-stage process
– scanning, OCR– verify, edit– add markup– Braille formatting & translation
• Separate tools for each task, duplication of documents, synchronization issues, ...

• Need to:– reduce cost of Braille production– provide open translation systems– make Braille production more open, available and
straightforward for individuals

RELATED WORK
Jan Engelen
• AutoBraille/NorBraille• DAISY XML Braille• Norway, Denmark, Iceland
• BrailleBlaster• DAISY XML / HTML / DOC / PDF Braille• open-source, multi-platform, fully accessible application
• Dotify• open-source translation system for Java• define components for sharing between implementations• establish more modular approach to Braille translation• (17h00 @ room HS 8)

APPROACH
Jan Engelen
odt2braille brings Braille to your Office
• Open Document Format (ODF) as master format– more common and more general-purpose than DAISY– widespread, well-established– many authoring applications– truly accessible (cfr. accessibility tools)– automatic conversion to Braille, DAISY (odt2daisy), Bliss
(Concept Coded Framework), large print, etc.
APPROACH
Jan Engelen
odt2braille brings Braille to your Office
• Free and open-source– http://odt2braille.sourceforge.net– OpenOffice.org / LibreOffice extension
APPROACH
Jan Engelen
odt2braille brings Braille to your Office
• Smooth integration in a major office suite– not mimicking word-processing features– integrated in existing mainstream word-processor– flat learning curve (experienced in Braille or not)– all functionality embedded in authoring environment– greatly simplifies Braille production workflow
APPROACH
Jan Engelen
odt2braille brings Braille to your Office
• Separation of content and style– 1 content, multiple forms– provide different presentations on an on-demand basis
using stylesheets• Ink-printing: rich layout (for sighted users)• Braille: basic Braille layout• DAISY• ...
– Braille stylesheet is stored with content and other stylesheets in the ODT file
APPROACH
Jan Engelen
odt2braille brings Braille to your Office
• Large scope and flexibility– ambitious: targets all of Europe (& whole world)– broad range of Braille alphabets, rules & conventions– flexible
• impressive number of languages• high degree of layout customisation• suitable for professionals
– understandable & user-friendly• transcribe according to existing Braille formatting guidelines,
requiring minimum of user interaction
APPROACH

odt2braille brings Braille to your Office
ARCHITECTURE
Jan Engelen
odt2braille brings Braille to your Office
• Preproccesor– transform original content/stylesheets to alternative
representation that is suitable as input for Braille formatter• Formatter
– produce Braille file in PEF-format– Liblouisxml/Liblouis
• PEF processor– convert PEF to other file formats– print on a Braille embosser– Braille Utils
ARCHITECTURE
Jan Engelen
odt2braille brings Braille to your Office
• Liblouisxml– open-source library for Braille transcription of XML– on top of Liblouis: open-source Braille translation and
hyphenation engine
ARCHITECTURE
Jan Engelen
odt2braille brings Braille to your Office
• Braille Utils– cross-platform API for embossing and converting Braille– Portable Embosser Format (PEF)
• accurate & unambiguous• structure: markup (XML) ↔ control characters• content: locale-independent Unicode Braille ↔ ASCII• PDF of Braille
– embossers: Index Braille, Braillo, Interpoint, ViewPlus, CIDAT, Enabling Technologies, Mountbatten
ARCHITECTURE
Jan Engelen
odt2braille brings Braille to your Office
• Valid & usable Braille < accessible source document• OpenOffice.org / LibreOffice extension• Make checking accessibility as straightforward as
checking spelling– errors & warnings– repair suggestions– (semi-)automatic repair functions
ACCESSIBILITY CHECKER
Jan Engelen

odt2braille brings Braille to your Office
• More extensive embosser support• More accurate Braille translations• Availability on more platforms (i.e. Mac OS)
