Let‘s dive in!
A Brief History of Apple‘s Face ID Technology
Face ID represents a groundbreaking advancement in facial recognition technology. But early visionaries laid the foundation many years before.
In 1964, scientists at Stanford Research Institute developed one of the very first automated facial recognition systems. It used a rudimentary version of computer vision to identify faces in photographs.
Throughout the 70s and 80s, facial recognition research continued at Universities. The studies focused on using algorithms to pick out certain facial features and landmarks.
It wasn‘t until the 90s that commercial interest picked up. Major computer companies like IBM started developing face identification software for businesses.
After 9/11, facial biometrics gained more traction for airports and law enforcement security uses. Systems could match faces against databases of photos.
All those early efforts paved the way, but it took a major innovator to bring facial recognition to consumers…
Apple unveiled Face ID in September 2017, introducing the world to easy, secure facial authentication.
The iPhone X was the first device with the TrueDepth camera system powering Face ID. This took facial recognition technology to the next level.
According to Phil Schiller, Apple‘s SVP of Worldwide Marketing, Face ID was in development for over 5 years before its reveal. The team went through many iterations trying to ensure it worked quickly, smoothly, and securely.
TrueDepth uses a dot projector, infrared camera, and flood illuminator to map the unique contours of your face. This enables Face ID to function accurately in all lighting conditions – even total darkness.
Apple continues innovating with each new iPhone lineup. The latest models feature faster Face ID performance, wider field of view, and new capabilities like Attention Aware Features.
Now let‘s look at some fun statistics around the impact Face ID has made since its debut.
Face ID Adoption Stats and Facts
- Over 90% of iPhone X users immediately adopted Face ID as their primary unlock method. They rated it highly for convenience and ease of use.
- Face ID unlocks 30% faster than the Touch ID fingerprint scanner, taking about 600-650 ms versus 850-900 ms.
- The average iPhone user unlocks their device 80 times per day. That means they use Face ID to unlock up to 9,600 times per month!
- As of May 2022, Apple Pay transactions using Face ID have surpassed 1 trillion (with 12 zeros).
- 99.999% of users who set up Face ID on iPhone continue using it regularly. Less than 0.001% revert back to a passcode.
- Third party apps integrating Face ID have risen 900% since its launch, allowing fast logins.
These impressive numbers show that Face ID has been quickly adopted by millions of users. The speed, ease of use, and security has led to skyrocketing engagement.
Next let‘s break down exactly how Face ID works before getting into the setup steps.
How Face ID‘s TrueDepth Camera Works
When Apple was designing Face ID, they knew that facial recognition alone wasn‘t sufficient. Previous face scanning techniques were too easily fooled.
TrueDepth represents a revolutionary camera system because it uses 3D facial mapping. This creates a depth model that is extremely accurate and hard to trick.
Here are the key components that make up the TrueDepth camera:
Dot projector – Over 30,000 invisible infrared dots are projected onto your face. This creates a 3D map of your facial contours.
Infrared camera – This special camera reads the pattern of projected dots and captures an infrared image.
Flood illuminator – Infrared light is used to recognize your face in dark settings.
Proximity sensor – Checks if a face is close enough to the screen before scanning.
Ambient light sensor – Adjusts the brightness of the dots based on the environment.
Processor – The built-in Bionic chip computes depth data using neural networks and machine learning algorithms.
All of these parts come together to create the distinctive 3D model of your face. This is why Face ID is so much more robust than standard 2D facial recognition.
Now let‘s walk through setting up Face ID from scratch…
Step 1: Open Settings and Tap Face ID & Passcode
The first step to enabling Face ID for the App Store is opening your Settings. Use the Settings icon on your home screen.
Tap the Settings icon to get started.
In Settings, scroll down a bit until you see Face ID & Passcode.
Tap Face ID & Passcode to begin setup.
Tapping this will prompt you to input your device passcode before proceeding.
Step 2: Input Your Device‘s Passcode
To access the Face ID settings, you first need to confirm your passcode. This is an important security measure.
Enter the 4 or 6 digit numerical passcode for your iPhone or iPad.
Type your passcode to proceed to Face ID.
If you don‘t already have a passcode enabled, you‘ll be walked through creating one.
Without a passcode, your iPhone won‘t allow you to enable Face ID. It‘s needed to protect your security and privacy.
Step 3: Position Your Face in the Camera Frame
Once your passcode is entered, the TrueDepth camera viewfinder appears. Center your face in the circular frame.
Center your face in the viewfinder to begin Face ID setup.
Position your face about 10-20 inches away from your device for ideal scanning results.
Try to frame your entire face in the circle with a neutral expression. Keep your eyes open normally.
Step 4: Move Your Head to Complete Face Scan
With your face centered, you‘ll be prompted to move your head slowly in a circle. This allows the TrueDepth camera to gather views from all angles.
Slowly rotate your head so the camera captures 3D data.
As you slowly pan and tilt your head, the circular dots will remain over your eyes and face. Just follow the on-screen guidance.
The TrueDepth camera is capturing over 50 high resolution images from different angles. Software converts these 2D images into a detailed 3D model.
Step 5: Face ID is Now Set Up!
Once your head is turned all the way around, Face ID setup completes. You‘ll feel a quick vibration and hear a sound effect.
The checkmark and confetti means you successfully set up Face ID!
That‘s it – you‘re all done! You can now start using Face ID to unlock your iPhone and make App Store purchases.
The initial scan takes about 15-30 seconds. After that, Face ID matches your face in milliseconds. It happens so fast you won‘t even realize it‘s working!
Now I‘ll explain how downloading apps works with Face ID enabled…
Using Face ID to Download Apps
Purchasing and downloading apps via Face ID only takes seconds. Just follow these simple steps:
Step 1: Find the App You Want
Browse or search the App Store until you locate the app you want to download. Free apps will have a Get button, while paid apps show the price.
