She already knows it, but that doesn't work in the use case she's using my phone to pay for something for example and I'm off doing something else.
Actually yes it did. Go back and watch the video, it's clear the first time he tried it was ok. It hit the limit for scans and requested the past code. There has been feedback to suggest that at demos it wasn't reliable as well.
Absolutely. Intense infrared radiation sources are everywhere, basically every thermal light source (light bulbs, fire, the sun) emits orders of magnitude more IR radiation than the iPhone X.
That is incorrect however. The IR radiation from the stars is extremely dim.
iOS uses a neural network to recognize your face. Every time it recognizes your face, it learns how to recognize your face better. If you grow a beard, it simply learns that you sometimes wear a beard and that your eye/nose-portion of your face is a more significant indicator of your identity. It's doesn't work like more traditional approaches to image recognition, meaning a pixel-to-pixel comparison to reference images. I can't say for sure, but principally neural networks don't even need to store an explicit model of your face to recognize it.
You can physically feel the home button and it's always in the same place, so you kind of remember where it is. It's called muscle memory, you do it two times and you never think about it ever again.
No, but there are some glasses specifically built to block IR.
Should be no problem. The phone is not taking a visual picture of your face.
It’s not about perfecting it really, it’s just not the same category of identification and it’s not a replacement without downsides. I think it would be a better replacement if the iPhone X UI was better, for starters slide to unlock (from right to left) would be easier.
That’s understandable, I wasn’t implying not to have Face ID but having both would be ideal, they both have their advantages and disadvantages. Face ID would be a lot better if the iPhone X UI was better. Touch ID, if it works for you, unlocks instantly when you turn the phone on when pressing the home button, and gets you straight to your home screen
When I was talking about preferring Touch ID, I had convenience in mind. It is more convenient unless you try to use it when having dirty, sweaty, or just wet hands. The button you press to turn it on also instantly unlocked the phone and lands you on your home screen. With Face ID, not only is it slower but you have to make sure tap to wake if it isn’t already, make sure it’s unlocks with your face, then reach down to swipe up to get to the home screen.
Yes, the IR image will be just as clear about whether your eyes are open as a visible light image. Have you ever seen the image from an IR-capable security camera? It's much like a monochrome visible light image. The range of IR that Apple is using isn't what thermal imaging cameras use - it's light just a touch beyond red so that we can't see it, but it's otherwise like shining a dark red light on something as opposed to heating it up.
Pay, specifically Uber, after booking takes you to the screen to pay, you see a summary transaction statement & then asks you to place finger to authorise - I don't have a clue how FaceID gets round this, if it says tap to agree, it's one more step, think I'll be skipping this version.
