The problem I find with doing as you say (simulating that the text display is at a position in space) is that next you might want some way to turn it on and off. Maybe a hand gesture? And then a way to manipulate the text? More hand gestures? Speech recognition? If it has to do significant processing you're going to need some external hardware. At what point are you basically simulating picking up a smartphone (for no benefit)?
