Nathan Bransford thinks they will soon be reality:
The screen will be in front of our eyes. We’ll blink to or wave our hands or just think about the page turning or it will just know somehow and it will turn. And let me tell you this: I, for one, welcome our coming hands-free-books overlords. Yes yes, the turning of the pages. Yes, the tactile experience of holding something in your hands as you’re reading.
Me? I’ll be sprawled out on a hammock or easily riding a subway or sweeping my floors or tripping over the sidewalks trying to read and walk down the street. Who knows! I just know I’ll be able to read more if I don’t have to have something in my hands to do it.
