Apple's new iPhone X ads tout animoji karaoke & Face ID
Apple on Monday released four new commercials for the iPhone X, all of them concentrating on the device's TrueDepth camera.

The first, "Animoji Yourself,", is a 39-second spot depicting a woman and several animoji singing along to the Big Boi song "All Night." Of the same length is "Introducing Face ID," which highlights Face ID's convenience, ability to see past fashion changes, and use in Apple Pay.
Two 16-second ads -- "Opens in the Dark" and "Knows You When You Change" -- are self-explanatory and stay on the Face ID theme.
Apple has made the TrueDepth camera a marketing tentpole since the iPhone X was first announced in September. The product's other signature feature is a 5.8-inch, edge-to-edge OLED display, which necessitated swapping a home button for touch gestures and commands using the volume and sleep/wake buttons.
At launch the product was in extremely short supply. New U.S. online orders are delivering between Dec. 11 and 18 however, and some retail stores may have units in stock.

It needs a model that is rigged with animatable blendshapes, this would normally be made by a professional rigger.
Then a developer has to map the data that comes from the iPhone to that model. It would be a good idea to get the likes of Disney/Pixar/Dreamworks/ILM to provide properly rigged models. They could sell the characters on the store.
Having the ability to just submit models for Animoji and not have to make an app would be a little easier but it's still a lot of work building and rigging the models. Even a professional rigger would take a few days mapping and testing dozens of blendshapes per model.

The workflow will improve the more people experiment with it though.
