"I didn't have any indication of where I was in the book"

Participant in EBONI hardware evaluation

Readers gain a sense of their place in a printed book via the page numbers and by comparing the thickness and weight of the pages read against the thickness and weight of the pages still to be read. It is important for this "sense of place" also to be present in the electronic medium; therefore, indications of a reader's progress through the book should be accurate and visible.


10.1 Provide indications of a reader's place in the book
10.2 Make these indications accurate and visible


Consult the following recommendation from the W3C Web Content Accessibility Guidelines 1.0:
Guideline 12: Provide context and orientation information
