Some of my ideas:
- Book covers (or virtual bookshelves) could be projected on white walls. Touching a virtual book would then automatically load it to an ebook reading device. [Alternatively, augmented reality devices could be used to display a library, but this would have the disadvantage that visitors could not browse through books.]
- Book dummies made from lightweight material could fill the bookshelves. Book dummies are hollow, foldable boxes in the shape of the original book. They have the book cover, spine, and back of the original book printed on them. Each book dummy contains a chip that stores the ebook (or a QR code that links to the ebook). In case the library owner needs to move, the book dummies could easily be folded and stacked.
Let me know about your ideas of the library of the future.
