Apple 1 1 Can face recognition be used at night?

Brush your face and unlock it. Will you not recognize it at night? Next, let's take a look at the evaluation of the use of iPhonex face id.

Iphone 1 1 can facial recognition be used at night?

However, on the day of the press conference, Apple's solution gave us a big surprise-directly deleting fingerprint recognition and unlocking the screen with facial recognition Face ID. So what is the success rate of unlocking Face ID?

Unlock in the dark.

Apple's facial recognition technology uses dot matrix to collect more than 30 thousand information points on the face, and uses infrared rays to recognize facial information, which can achieve the same function as touch ID. Then the most common special scene we encounter is unlocking in the dark at night.

After testing, there is no pressure to unlock Face ID in almost all black conditions. Because infrared ray is used to scan facial information, it can be easily unlocked in dark conditions.

Outdoor backlight condition

When we usually take pictures, we will encounter a black face when taking pictures in the backlight environment, and we can't see the face clearly. So when backlighting, can iPhone X accurately recognize facial information?

Under the backlight condition, the performance of iPhone X is also very good, and it can still be easily unlocked even in the glare of the sun. In fact, it is similar to the reason why it can be unlocked under dark conditions. IPhone X doesn't use a camera to shoot, and it won't have backlight like when taking pictures. When infrared ray scans facial information, it will not be affected by this light.

Will you transfer money at a glance?

Before, everyone joked the most, that is, my wife chose something and told you to pay back. Is that really the case?

After the actual test, if you just look back, you won't pay. Similarly, if it is only a flash in front of your eyes, it will not be unlocked immediately. In the end, the transfer will be successful only when you face the mobile phone seriously.

Put it on the desktop to unlock it.

The result of the last test shows that the mobile phone can only be unlocked if it is faced seriously, so can it be unlocked if it is placed on the table and not picked up?

We experimented. The mobile phone was placed horizontally on the table and changed a lot of angles. The mobile phone was not unlocked successfully, which means that if you want to unlock it, you still have to pick up the mobile phone. This has both advantages and disadvantages. It's convenient if you just look at the time. But if you originally wanted to unlock it, it would be a little more troublesome than the previous touch ID.

Can it be unlocked when shaking?

We also tested a very extreme way, that is, in the case of violent shaking of the head, to see if it can be successfully unlocked. In the video a few days ago, we also saw that someone could unlock it when shaking violently, but our results were different from theirs.

After experiments, iPhone 1 1 won't recognize unlocking when the head shakes greatly. However, if the shaking amplitude is small, it can be successfully unlocked. It may be that when the mobile phone vibrates greatly, it will be unlocked only when the last pause is recognized.

After our test, the success rate of face recognition of iPhone 1 1 is still very good. When in normal use, it can be easily unlocked in dark light or backlight.

The legendary terrier on the Internet did not appear on iPhone 1 1. They will not be "routine" by their wives after turning around, nor will they be secretly unlocked by their girlfriends while sleeping.

Therefore, the facial recognition of iPhone 1 1 is still very reliable in terms of security.
