It's so much better than staring down at a cell phone.
When the iPhone's App Store came out, there were a bunch of apps that were all about overlaying information on real-time real-world imaging. One of them was navigation where you'd hold your phone up (horizontally) and it would overlay the real world with lines and arrows. I wonder why that never really caught on.
There was another great one that was an SMS app that overlayed your conversations on the camera feed, so you could walk and text at the same time without falling into a mine shaft, or stepping in dog poo, or whatever. With today's technology, that could be just a toggle. Again, for some reason people didn't like it.
