In a printed book, structural parts like chapters are clearly identified visually through specific styling. Pour les personnes qui utilisent des technologies d’assistance, il est nécessaire de donner cette information sous forme informatique à l’aide des arguments correspondants qui sont les types EPUB et roles ARIA. This is also useful information on the day when you want to update your content or publish it in a more recent or different format.

Objectives

• Ensure users of assistive technologies can navigate and understand the structure of the book.
• Provide a clear identification of chapters and other portions of the book.

Implementation

• Use appropriate ARIA keys to identify different sections of the book, such as chapters
• Document the ARIA roles used and their implementation to facilitate maintenance and future updates.

Control

• Use screen readers like NVDA, JAWS, or VoiceOver to navigate the book and verify that sections are correctly identified.
