What is the technology used in iOS 11 settings migration (moving blue dots / particles pattern / animated QR code?)

 During the setup of a new iPhone 8 / iPhone 8 Plus / iPhone X, there is a step for migrating the settings from another iOS 11 device. On the old device, it says: > # Set Up New iPhone > Use your Apple ID "xxx@xxx.com" to set up your new iPhone. On the new device, it says: > # Quick Start > If you have an iPhone or iPad running iOS 11, bring it nearby to sign in automatically. > > If you want, you can also set up this iPhone manually. After tapping "Continue" on the old device, on the old device, it says: > # Hold Your New iPhone Up to the Camera > Position the pattern in the circle On the new device, it says: > # Waiting for Other iPhone... > Position this image in the frame of your other iPhone. A pattern of moving blue dots appears in the new device, as shown in this picture: http://www.idownloadblog.com/2017/06/05/automatic-setup-feature-ios-11/ And in this video: https://youtu.be/tHxhZu97pXc I believe it works like QR code, but it is not. Does anybody know what the name of this technology is?
