It's really interesting Apple has put the overkill face ID sensor in the iPhone. I'm sure future iPad's will have the same too, possibly with even better hardware. I also believe accurate tracking of the eyes of the user will have tremendous impact on the applications that can exploit AR. AR is a tremendously promising field and Apple has gone the easy way, to capture the market and developer mind share. Oculus Rifts' and HoloLens' have failed to adequately capture developer mindshare as on date. Just look at the measure app. It's a tremendously useful app. Though I know it will not have much accuracy, it will satisfy most use cases for normal users. I am excited about the future of AR apps. I can see a lot of potential applications in Engineering, Medical, Civil surveying, etc.
