According to Bloomberg's Mark Gurman, Apple's forthcoming augmented- and virtual-reality headset can accurately reproduce a user's face and body for FaceTime calls.  Gurman also believes the headset's numerous cameras and sensors will allow users to manipulate virtual objects using their eyes and hands.  Because of the next-generation hand and eye tracking capabilities, the Apple headset is unlikely to require controllers.  Gurman also suggests that Apple headset users will be able to view and use their Mac computers while wearing the headset.  Moreover, the headset's battery will remain separate from the headset, most likely connected via a cord so the battery can sit in a user's pocket.
