What if the high end iPhone had a special accessory called the iLens? The way that it would work is that you'd insert the iPhone into the iLens. The iLens would function like actual eyeglasses, albeit a special pair optimized for different visual Passthrough, Overlay and Immersive modes.
The platform is iOS; it's Siri, ARKit, Messages, Video Capture and Apple ML. It's AirPods and Apple Watch, all interconnecting
Like every other Apple Device, iLens has its own set of Native Sensors and Capabilities specific to the Device.
