Facebook has applied for patents via which it will use your face as Emoji. With face identification technology, Facebook will find via your tagged picture the best photo and replace it with emoji. For instance, if you want to use Smiley, Facebook will search your face put a smile on it and post instead of emoji.

Facebook will now use your face for Emojis.

Facebook will encourage users using the photos that can be easily converted into Emoji or whose facial expressions can be like Emoji.

This to further remind you that reactions came into being after 2 years of patent registration, so the custom Emojis will also take some time to roll out.
