Face Unlock for Five Year Olds

How does Face Unlock work? We explain it to you like you’re five years old.

When you set up Face Unlock for the first time, the front camera takes pictures of your face. The processor saves information about your face, like the distance between your eyes, on your phone for later use.

To use Face Unlock, you have to wake the phone. One way to do this is to double tap the screen.

At the bottom of the screen, there is a smiley icon. If your phone has Face Unlock on, then the smiley will appear.

The front camera looks at your face and software follows a set of rules to compare your face to the image information you saved during the set-up process.

The software looks at 100 parts of your face and checks for a certain number of matches. Face Unlock works with eyeglasses or hairstyle changes because the software looks at points all over your face.

The software also checks for shadows and reflections to make sure it’s seeing a real person and not a picture. If enough tests are passed, then the software will send a command to unlock your phone.

Face Unlock takes only 0.4 seconds to unlock your phone and take you to the home screen. That’s faster than the blink of an eye. Try it for yourself on the OnePlus 5T 😉
