How Does Eye Tracking Work in iOS 18 (tutorial)?

Eye tracking in iOS 18 is like having a super-smart friend who can tell exactly where you’re looking on your phone screen.

Imagine you're playing a game on your iPad, and instead of tapping the screen with your finger, you just look at what you want to choose. That’s eye tracking, it uses special sensors in your device to know where your eyes are pointing.

How It Works

Your iPhone or iPad has tiny cameras inside that watch your face and eyes. They’re like little detective officers taking notes on where your eyes go.

When you look at something on the screen, those cameras send messages to the phone’s brain (the processor), telling it: "Look at this spot!" The phone then knows exactly what you want to click or choose, without you even touching the screen!

Why It's Cool

It’s like having a magic wand that follows your eyes instead of your fingers. You can play games, read books, and even control apps just by looking at them.

No more finger taps, just look, and it works!
