Master these skills and enter FaceID to lie in the bed and unlock it in seconds.

Apple released the first full-screen mobile phone iPhone X this year. In order to increase the screen share, it canceled the original home button, and the fingerprint unlock was replaced by face recognition. More interestingly, the iPhone on the front of the iPhone X is not a square display, but a shaped screen, also known as "Liu Haiping."

This "bang" integrates many components: from left to right, in turn, infrared lens, flood light sensor, distance sensor, ambient light sensor, speaker, microphone, 7 megapixel camera, dot matrix projector. The most important of these are the infrared lens, the floodlight sensing element, and the dot matrix projector. It is these three important components that provide important technical support for the face recognition of the iPhone X.

When Face ID verification is unlocked, the pattern is first drawn through the "dot matrix projector" , and then the "infrared lens" is used to confirm whether the data matches. If it matches, then the verification is successful and you can unlock or pay.

Since the release, the reliability of the iPhone X's Face ID has been controversial. From a security perspective, the face ID created by the Face ID through the dot matrix projector is unique, and even the twins are almost impossible to untie the same. The iPhone X, so the security is quite reliable and safe compared to the facial recognition made by the image recognition principle.

In many scenes, facial recognition is still not convenient for fingerprint recognition, such as playing a mobile phone in bed, unlocking it is not so easy to use facial recognition. Of course, this is not to say that you can't use the face to unlock in bed. This is fine. The trick is to take a little thought when you enter facial information.

1: When recording the face ID, the system is prompted to record twice, and twice is also prompted to shake the head 360 degrees to complete, in fact, the first time you do not need to shake your head, put the phone as close as possible to your face to make the phone photo Go to your eyes and nose, then slowly move the phone away from the face until your entire head is illuminated by the phone. At this time, the system prompts that the first entry has been completed, and then enters the second face, the second time. Faces must shake your head, let the phone shine through the head, don't be too far away, don't rely too close, just shine on the entire head.

2: This method should be entered together with the first point above. It is the backlight behind us. For example, if you record at home, turn on the lighting in the hall of your home and stand next to the headlights (not under the headlights, but next to it) ), then the body will also be rotated 360 degrees when recording the first face (similar to a glowing thing around you when you record the face around you, the advantage is that whether you go down or back light you It can be unlocked in seconds, which is why so many people can't face unlocking when they are out of the sun or reflective.

After entering the facial information according to the above method, the iPhone X can be unlocked in seconds, whether it is at a close distance, a long distance, a smooth light, a backlight, or a bed. Students who feel that facial recognition is not working can try this method.
