I see a conflict in the human behavioral pattern here, why because
- You render a book in a skeuomorphic fashion
- and force the user to behave differently
- Left Right arrows are placed Top Bottom (this itself sounding awkward right??)
If the concern is a large screen how large it is?
if it is a huge 50" TV kinda screen then better to have the buttons “bottom center” (<- -> like this) of the book so that it is easily reachable as well as retain the natural human behavior with a book.
Also we never experienced a left and right arrows in top to bottom order.
