The document discusses the odt2braille software project which aims to enable users to generate Braille documents from OpenOffice.org. It provides an overview of the motivation, objectives, methodology, results and future outlook of the project. The methodology involves building an OpenOffice.org extension that reuses existing Braille transcription libraries to convert OpenDocument Text files to Braille output that can be embossed or exported to file formats like Portable Embosser Format. An alpha version has been released that supports a small number of embossers. Future work includes adding support for other OpenOffice.org applications like spreadsheets and presentations as well as additional embossers and formats.

4. Methodology

5. Results

6. Conclusion & Outlook

7. (Time for demo?)

9. important for functional literacy

10. only reading method for deafblind persons

12. AutoBraille & NorBraille: multi-volume Braille books based on DAISY

13. Dots: open-source Braille transcriber for GNOME (relies on liblouisxml)

14. Tiger Software Suite (TSS), Braille Maker, WinBraille: embossing from MS Word and other Microsoft applications

16. Reduce or eliminate the need for editing Braille codes after export

17. Emboss directly or just export

20. liblouis: Braille translation engine

21. pef2text (DAISY Pipeline): converts Portable Embosser Format to generic or embosser-specific format

22. library from odt2daisy

23. odt2braille Components Architecture of odt2braille OpenOffice.org with odt2braille extension: uses UNO API and configuration information; configuration information is passed on to the XML transformation (which uses DOM and XSLT); output of XML transformation is fed to Braille transcription (which uses liblouisxml and liblouis); output of Braille transcription is fed to export or emboss process.

25. Export to “Braille Formatted files” (.brf)

26. Export to Portable Embosser Format (PEF): embosser-independent; uses XML and Unicode

27. User preferences stored as metadata

28. Screenshot: Settings - General Screenshot of Settings dialogue Settings dialogue window with a list of steps on the left side and a form on the right side. The list of steps is: 1. General, 2. Lists, 3. Tables, 4. Page Numbers, 5. Languages, 6. Table of Contents, 7. Export/Emboss. The form on the left contains form fields for Language (currently showing English - US), Contraction level (currently level 2), Include transcription information (checkbox), Transcriber (name to be filled in), Include volume information (checkbox), Include list of special symbols (text field), Include transcriber'ts notes page (text field), Create preliminary volume. The bottom of the dialogue displays the buttons Cancel, Back, Next and Save.

The bottom of the dialogue displays the buttons Cancel, Back, Next and Save.

31. Support for larger set of embossers

32. Availability on non-Windows platforms

33. Possibly support for other formats such as Universal Tactile Document (UTD)

34. Accessibility check to be run before (Braille/DAISY/PDF) export?
