Everyone loves the AR cards in the Nintendo 3DS. Sony's noticed their popularity and has since announced its plans to release an augmented reality suite of its own for the PlayStation Vita.
Bringing gaming into the real world, the AR Suite comes with cards that serve a variety of different purposes, allowing players to play games that involve puzzle solving, shooting, and even sports.
Arguably better than the 3DS, Sony's AR Suite has been given a short technical demonstration of what it has to offer.
