Apple has filed a patent explaining the process of automatically generating Memoji. Avatars will be created based on scanned photos of users.
iOS will use the image of the person to determine his facial features, then the algorithm will select digital analogues and compile them into an avatar. According to the new patent the facial expression will also be fixed at the time of the creation Memoji.
Apple specialists will bring this patent to life, but this will happen no earlier than in iOS 14.
