Video: The iPhone X ultimate Face ID test

I think it’s a certain percentage of the face. That it needs to recognize to unlock. 

Hi! In the video, you said that Face ID didn't work when your eyes were closed which you suggested would prevent someone from pointing the phone at you to unlock it if you had phone asleep and they had access to your phone. But later in the video you said it worked while you were wearing sunglasses. Did you mean that FaceID recognized you? If so, that would seem to contradict the eyes-closed test, right? And wouldn't that mean that someone could access your phone (by pointing it at you) if you had fallen asleep with your sunglasses on? Just want to see if I understood the video correctly. Thanks!

IR will penetrate most sunglasses. His eyes would still have to be open behind the sunglasses, though. There is a specific wavelength that some sunglasses block (940nm wavelength) which will prevent Face ID from working because it won't be able to read your eyes.

PS: It'll be interesting to see sunglasses start to advertise that their glasses work with the iPhone X.

When you take the percent of people that won’t be able to unlock their IPhone X due to them wearing a mask, helmet, face protection (ie: certain jobs that require it), compared to the percent of people who wear gloves and can’t unlock their phone with Touch ID due to them wearing gloves; it’s probably a wash, so in that case, the more secure technology should be welcomed. I think it’s great bc lots of times I get out of the shower (listening to AppleInsider Podcast), and I want to access the control settings on my phone to check a text and I can’t use Touch ID bc my hands are wet...

We need a shaving cream test on the face!!! Real world test when shaving....will it work?
i say yes bc it should read your eyes and nose even though the contour of your face is hidden from shaving cream.
