Those cameras will enable the device to track eye movements as well as hand gestures. It’ll also have LiDAR sensors, like those found on the iPhone 12 Pro and iPad Pro, to help measure the distance between objects in the real world and properly scale and present virtual objects in a real-world space.
The headbands for the device are said to be interchangeable and will include “spatial audio” technology, similar to what’s in the AirPods Pro and AirPods Max. And it sounds like Apple is working on its own in-house chips to power its headset — no big surprise given that it makes the silicon powering nearly all of its hardware these days.
