Adapted with permission from EPUB 3 Best Practices (O'Reilly Media) In EPUB 3 we have an ebook format that embraces that there is no single universal way to access information. Any reader may switch between reading modalities at any time. Sighted readers, for example, will switch and listen to books be read in many situations not amenable to visual reading, and will often read captions instead of listening to a video. Nonvisual readers may switch between tactile and audio for many of the same reasons.
