Apple’s newly introduced ARKit framework lets developers create augmented reality experiences that can be accessed using compatible (A9- and A10-processor-powered) iOS devices — meaning iPhones and iPads released since September 2015. The software only recognizes horizontal planes today, but this will change in the future, and it’s expected to help companies explore new opportunities, from online retail to gaming to unified communications.
