Regarding digital books…

“In the making of digital books, the tools which will have particular importance will be multimedia storytelling, infographics, and the interactive presentation of data and information. The focus will therefore be on the possibilities offered by the integration of different communicative codes (text, images, audio, video) in the fields of information representation, multimedia narration, the ability to motivate and capture attention, as well as encourage comprehension, memorization, abstraction and reasoning skills.”
