2011. MIT Press.
MIT Press approached me as I was graduating asking for a modern eBook-as-an-app made specifically for the iPad. As John Palfrey wanted a cutting edge book no other platform (like iBooks) at the time did what we created.
The book was accompanied by a number of video interviews to be integrated directly into the reading experience, as shown in the screenshots. They provided one way of of several ways of diving deeper into subject matter. Recognizing the not all IP terms are accessible to the general population, we wrote scripts to cross-link the terms in the glossary as they appeared throughout the text to provide inline definitions without losing the larger context by splitting the text in place. Additional areas had callouts to outside researches on the web for an in-app browsing experience, as well as links to relevant case studies with the ability to easily navigate back to the main book.
However my favorite feature was actually an easter egg -- the ability for John Palfrey to sign the book itself! eBooks lack the ability for authors to sign their works, so we created a special gesture that would turn the touchpad into a drawing surface. The signatures would be unique to a given app purchase and stored in the cloud so they could be restored in the future. Thus they truly approximated what authors have been doing with physical books for centuries.
