You can already make calls or send texts from your Apple Watch, so why not a FaceTime stream? Currently, of course, you can’t because of the lack of a camera. But Apple is working on ways to add a camera to your wearable without significantly increasing size or weight.
Most recently, Apple’s development in the area has focused on embedding a camera module into a future Apple Watch band. Combined with some of the other band-related patents on this list, that could hint that future Apple Watch straps may be much more advanced and intelligent than current offerings. Such a band could even bring Face ID to the Apple Watch for improved authentication and security.
