There is this rumor everyone is talking about, a number of sensors on the iphone, supposedly for face tracking and identification. From a number of discussion I have read It became apparent that the only way this could work flawlessly is If the sensors could identify a face in a really wide angle. Lets admit that is possible, and lets jump for a moment to augmented reality. AR is the future but the future of AR is not the little window that is the screen of the Iphone (realistically the holy grail would be transparent sun glasses form factor but full of tech) My teory is that until Apple is ready for there stand alone AR glasses and as a step in the right direction, the iPhone 8 will fit into a glasses head strap contraption (like the one for VR in Samsung smartphones). With this viewer the AR objects in the tiny window that is the Iphone screen will exist within the entirety of your field of view cohabiting with the video fied of the real world. Now to the really wide angle detection sensors one more time. So, you are home alone, with the Iphone strapped to your head and you see this beautiful AR images within the video feed, in the video feed you also see your body, your arms and your hands... My believe that the rumored sensores are not for face tracking (or only for that) what they will do is detect the exact position of your head, shoulders, harms and hands, basicly 1 to 1 inside-out body tracking, the perfect way to interact with the Augmented reality world (also VR). What do you guys think? Besides...it is a rumor so It can also be nothing.
