6. Broadly speaking… 6
E-books can be made accessible
— but it’s more than just handing someone a talking
device
It’s all about structure…
— navigation
> TOC, headings, tables, lists
— seeking/finding
— investigating objects
— reading order
7. Broadly speaking… 7
…and control
— multimedia players
— interactive objects
— the reader itself (hardware or software)
8. What’s an accessible e-book? 8
More than just a talking book or a talking device
Access to structure:
— text elements (chapters, headings, paragraphs, sentences)
— images (short and long descriptions)
— data tables (header vs data cells; X/Y orientation)
— lists (number of items; nesting)
Access to controls
— multimedia (player controls; captions; descriptions)
— interactives (controls; Flash or otherwise)
— system (menus and special features; stores; hardware)
11. E-book formats 11
E-books are available in a variety of formats
— EPUB 3
— PDF
— HTML
— AZW
— DOC
— TXT
Not all formats provide mechanisms for delivering an
accessible e-book
12. E-book formats 12
There is no such thing as push-button accessibility
Author is responsible for providing an accessible
document
— basics:
> provide a TOC and use headings
> identify/describe images
> mark up forms (e.g., tests) properly
> mark up data tables
> provide adequate contrast and clear layout
— not unlike accessible-HTML basics
13. E-book authoring 13
InDesign (EPUB, PDF)
iBooks Author (EPUB 3 variant (.ibooks))
— exports books for iPad only
— accessibility guidelines coming soon
Adobe Acrobat (PDF via source files from Word,
InDesign, OpenOffice, others)
OpenOffice (EPUB via Writer2ePub; PDF)
Pages (EPUB)
Online services or converters (Calibre, Lulu, etc.)
14. E-book accessibility: hardware 14
Hardware accessibility varies
— controls aren’t always clearly identified
— TTS not available or may be inadequate
> TTS may only allow access to text, not to
system
> DRM may affect TTS
15. E-book accessibility: software 15
Software accessibility also varies
— may not be usable with screen readers
— TTS not available or may be inadequate
> may only allow access to text, not to system
> DRM may affect TTS
> may not identify elements such as images or tables
Nook/Kindle desktop and mobile software readers not currently accessible
to screen readers
Adobe Reader, Adobe Digital Editions are (reasonably) accessible to
screen readers
iBooks is reasonably accessible on iOS devices
Accessible Kindle plug-in for Windows
— requires a screen reader
— TTS reads book text; screen reader reads menus and controls
17. DAISY/DTB 17
DAISY Consortium (Digital Accessible Information
System) promotes standards for digital talking books
(DTB)
A DTB is a multimedia representation of a print
publication
— DTBs can contain text, text+audio, audio only
— video support in development
DTBs can be read using dedicated hardware or
software
20. DTB general information 20
DTB hardware readers have no visual component
DTB software readers usually have a visual component
DTBs are inherently accessible and are (usually) highly structured
Multiple navigation modes
> headings
> words/sentences
> paragraphs
> chapters
> images (with descriptions)
Depending on the DTB, these modes are all available in both text
and audio modes
