> I've seen children accustomed to using touch interfaces blurring the line between physical and virtual, i.e swiping at physical objects like books, photos, even walls. I've not seen this behavior with those used to non touch interfaces. Recently I started reading actual paperbacks again after a few years doing most of my reading on a tablet; I was quite amused to find that sometimes I'd try to swipe the pages instead of turning them. I'm in my forties. My first computer was in 1981. I've got decades of interacting via keyboard behind me and this still happened to me. Habit is a powerful thing.
