Ever since Apple announced its latest iPhone X, the new iPhone was in news for two things – its $1000+ cost and its new Face ID feature. While the cost may dampen many buyers from buying an iPhone X, there is curiosity over how exactly does the iPhone X’s Facial Recognition Tech or Face ID work.

Apple’s iPhone X

Apple announced iPhone 8 and iPhone X on September 12 in a filled hall in Cupertino, California. iPhone 8 stood out as ordinary incremental smartphone over Apple’s earlier iPhone 7 but iPhone X caught the fancy of the audience and tech geeks as well. This was due to two new signature features that Apple introduced in iPhone X – the all-screen design (bezel-less design) and the TrueDepth camera that powers the phone’s Face ID facial recognition system.

While bezel-less design smartphones have been around for some time and even Samsung’s Galaxy S8 is a bezel-less Android smartphone, one could easily say that Apple copied the feature from Samsung for iPhone X.

What makes iPhone X stand out is the all-new Facial recognition tech called Face ID that is supposed to be more secure than any other facial recognition system out there and revolutionize the way a smartphone for unlocks and transaction authentication. If proved successful, Face ID tech could replace fingerprints, retina scans, pattern locks, and code locks for all things from your Gmail account to your bank account. However, the technology is raw and much has to be done with it before it can be commercialized.

How does Apple’s iPhone X Face ID Work?

The one question that tech forums are filled with is how does iPhone X’s Face ID actually work. Although everything the Face ID system does is invisible to the naked eye, a new video actually lets us see the magic happen.

Actually, Apple has put a complex array of cameras and sensors on iPhone X to make the Face ID possible. Apple calls this array of cameras and sensors TrueDepth camera. It’s the advanced, depth-sensing facial recognition system Apple built for the iPhone, miniaturizing Kinect technology to fit inside a phone.

This image shows the array of sensors and cameras on iPhone X. One of the components on the top left called Dot Projector is the one that powers the iPhone X’s Face ID.  Apple’s new TrueDepth camera tech uses an array of dot projector to shoot 30,000 infrared dots at your face to create a 3D depth map of it.

If you wish to learn more about it, visit the Reddit thread by visss9 who observed the dot projector in action in a hands-on iPhone X video in action.

The dot projector operates on the infrared wavelength, which is invisible to the human eye but visible to cameras. visss9  compiled a list of everything that happens with the iPhone X when Face ID is triggered. visss9’s finding gives a view into how Apple’s TrueDepth camera and the dot projector actually work.

First instance: 0:10 – 0:18 What’s happening: Animojis
Second instance: 0:28 – 0:35 What’s happening: Portrait Mode on front camera being used
Third instance: 0:38 – 0:41 What’s happening: Face ID verification. The infrared camera on the left side of the notch also blinks momentarily.
Fourth instance: 0:42 – 0:45 What’s happening: Animojis
Fifth instance: 0:58 – 1:02 What’s happening: I have no idea, but both the infrared camera and the dot projector blink right before the screen switches off.

There you have it. This is how the Apple’s new iPhone X Facial Recognition tech works and the Face ID opens your iPhone X. However, what would happen if I cut somebody’s head and put it in front of Apple’s iPhone X? Would it open the iPhone X for me? The tech is still raw that even Apple is having problems shipping iPhone X’s to its buyers.

The question still remains! Will Apple’s Face ID tech replace passwords and codes in near future? I did say no to that!
