It's not mind-blowing for something with a depth sensor or at least stereo cameras. I'll have to hunt down the vid, because it might actually be quite good for a legacy device.Apple showed off ARKit with a simple demo involving the placement of a virtual mug on a coffee table. The mug detected the table's position, of course, and rested on top of it. Then a virtual lamp joined the party, and Apple called attention to the dynamic shadow created by the mug. If that wasn't exciting enough (and if you're familiar with AR it probably wasn't), it also had Wingnut AR demo a game on that same table. The whole thing "lived" on the table and responded to whatever the phone's camera picked up. Again--not mind-blowing, but still pretty neat.
