What does it mean to point your face into the frame during face recognition?

Facing the screen in face recognition means placing your face in the center of the phone screen, that is, within the circle within the screen. In this way, face recognition can be completed according to his wishes, thereby lifting the anti-addiction. So I think facing the screen in face recognition means pointing the front of the lock phone towards the screen. Then put you into the circle, blink, and then close your eyes.
