Augmented-reality apps are already available for tablets and smartphones, but they're rudimentary compared to what's coming. Today, for instance, the aptly named Augmented Reality app for iOS devices displays points of interest (including restaurants, transit stops, and coffee shops) over a live view of a real-world environment such as the street you're standing on. AR is better suited to tablets than to smartphones, as graphical overlays are easier to view and interact with on a tablet-size screen.
So what does the future hold for AR? As this Hidden Creative video illustrates, it may include the ability to point a tablet/phone camera at a hotel, see an overlay of vacant rooms, and book a reservation on the spot.
