iBooks Author: How to make your books accessible
When you create books in iBooks Author, use these guidelines to make your books accessible to the visually-impaired.
iBooks Author includes an Accessibility Description in the Widget inspector. Use this to include descriptions of images and objects to be read by VoiceOver when users view the book on an iPad.
Use these guidelines to make your iBooks Author book as accessible as possible:
- Always provide accessibility descriptions for any images used in the book, including background images.
- When you create a widget that has elements that are not described with text, provide accessibility descriptions for each of those elements. For example:
- Provide an accessibility description for each picture in a Gallery widget.
- Provide an accessibility description for each picture in Review widgets, as well as for answers in Review widgets for "Drag Label to Target" and "Drag Thumbnail to Target" questions.
- In the Review widget, make sure to use accessibility descriptions that don't reveal the answer to the question.
- Provide an accessibility description for each equation or mathematical expression.
- Avoid embedding text in images. If you do embed text, make sure to include that text in the accessibility description.
- Make content in HTML5 widgets accessible using WAI-ARIA. More information about WAI-ARIA is at these websites:
- Always give a basic description of a figure next to the figure number.
