AR (Augmented Reality) is a much harder technology problem to solve than VR (Virtual Reality). Here is why.
Although both technologies are creating illusions to fool your eyes and brain, VR has the easier task because it can shut out the real world to allow you to experience an immersive virtual world. AR on the other hand must overlay virtual content over the real world allowing you to experience both.
This is why AR technology is taking a little longer to come to market.
However massive strides have been made already (think Microsoft HoloLens here) and next week when Apple releases iOS 11 any device that has the Apple A9 and A10 processors will be able to run ARKit apps.
The following devices use these processors:
iPhone SE iPhone 6s iPhone 6s Plus iPhone 7 iPhone 7 Plus 9.7-inch iPad (2017 model) 10.5-inch iPad Pro 12.9-inch iPad Pro (2017 model) 9.7-inch iPad Pro (2016 model) 12.9-inch iPad Pro (2016 model)
AR on the phone is a precursor to the head mounted display that Apple will bring to market. We are about to experience a technology shift of dramatic proportions. The Big Bang.
Below is another example of what AR is capable of delivering.
