Apple just published a page dedicated to Augmented Reality in the latest versions of iOS. It is a good page overviewing some of the use cases we’re already seeing with AR.
This is just the beginning.
I’ve written about AR many times, so I won’t reiterate everything today. But look at these use cases and imagine them being accomplished, not within a small hand-held rectangle, but in full view using small glasses or — dare I even say it — contacts. It will be a while yet. But this first phase will set a lot of the UI, gestures, etc. that will be implemented in whatever the next generation of hardware is.
