Ok, the guy demoing the iPhone X just had to switch to the backup phone because the Face ID on the first one didn't work quite smoothly.

actually, the phone had been rebooted, so he needed to unlock with a pin to activate it.

  Still, at least I didn't notice, and probably the average user didn't either, which makes it just look as a major blooper. I loved the phone though.

    at least he knew the password and wasn't relying on the face recog to get into the phone, that could have been rough

      IIRC he didn't use the passcode, they switched over to a backup phone. For presentations like these you always have multiple devices standing by, ready to flip over to at a moment's notice.

        I'm pretty sure the backup phone had an imitation of Face ID unlocking.
        jads 9y ago
        How are you "pretty sure" about that?
- vernie 9y ago
  Actually, the message ("Your passcode is required to enable Face ID") was identical to the message when too many failed Touch ID attempts are made, not when a phone is rebooted ("Touch ID requires your passcode when iPhone restarts").

I had this feature on my 950 (Windows Phone). It was poor. Slower and more error prone. Environmental changes such as extreme lighting (being outside) or wearing sunglasses stopped it from working. Windows Hello and compatible webcams work really well in a stable desktop environment mind. I've just rolled them out across my firm.
- zherbert 9y ago
  Come on, your 950 didn't make a 3d dot-map of your face. This is very different.
  - TheAnimus 9y ago
    Yes it did an infra-red dot map of the face. https://www.windowscentral.com/how-iris-scanner-lumia-950-and-950-xl-works https://www.windowscentral.com/how-iris-scanner-lumia-950-an... Amazing, -4 for mentioning this isn't a new feature. This is exactly how the kinect works, how windows hello enabled webcams work.

      That article doesn't say anything about an infrared dot map of the face - just that "the infrared camera is first used to light up your eyes". Additionally, https://en.wikipedia.org/wiki/Iris_recognition https://en.wikipedia.org/wiki/Iris_recognition says "Iris recognition uses video camera technology with subtle near infrared illumination to acquire images of the detail-rich, intricate structures of the iris which are visible externally" which doesn't involve any kind of infrared dot map.

      It didn't have face detection at all, it had an iris scanner. Where in that article does it say infra-red dot map of a face? From https://www.petri.com/windows-10-tip-using-the-lumia-950-with-windows-hello https://www.petri.com/windows-10-tip-using-the-lumia-950-wit...: >Let’s be clear about how Windows Hello works on the Lumia 950. It doesn’t use facial recognition, but instead relies on the front camera and a nearfield IR diode so that the camera can clearly see your iris. When you enable Windows Hello for the first time, your iris is scanned and a cryptographic hash is generated and stored securely on the phone. When you attempt to unlock the device using Windows Hello, a new hash is generated and compared with the original, and if the two match, access is granted. >Facial recognition on the other hand, as used in some new notebooks designed for Windows 10 and Intel’s RealSense F200 camera, uses three different methods to recognize your face: infrared, a standard camera, and a 3D camera. This technology requires more space inside the device and as such isn’t suitable for use in phones, but unlike iris scanning works at a distance. You didn't get downvoted for mentioning a feature already implemented elsewhere, you were downvoted by trying to claim a device did something it clearly didn't.

So you can't unlock your phone after coming from a plastic surgery? I always thought chances of finding facial-doppelgangers are higher than fingerprint ones. Is that really wrong?
- developer2 9y ago
  You always have the password as backup to unlock. If your appearance were to suddenly change remarkably, such as via plastic surgery or a horrific accident, you would set your new face after unlocking with the password. Based on their phrasing, I'm assuming the "adaptive" aspect means that slow changes, such as gaining or losing weight, will progressively train the existing face - without it ever failing to recognize you because you passed some weight threshold. Same would go for growing a mustache or beard. As to whether you can shave off a 5-year beard and have it still recognize you without manual intervention, that would depend on how much the algorithm cares about your chin and lip regions vs. the rest of your face. Based on the demo, the hair on top of your head is 100% ignored.

  Apple claims that the odds of a random person's finger unlocking your iPhone with Touch ID is 1 in 50,000, and the odds of a random person's face unlocking Face ID is 1 in 1,000,000.
  - jandrese 9y ago
    I wonder what the odds are of someone unlocking your phone with a picture of your face? I've heard lots of biometrics companies say that their system is immune to such simple hacks in the past, only to immediately fall to such simple hacks in testing.

      This time they’ve got an infrared sensore, as well as two cameras with different focal lengths, so they should be fine.
