Smartphones use a special kind of camera and clever software to know when you're looking at them. It’s like how your eyes follow something that moves, the phone notices where your eyes are focused, and it knows if you’re really paying attention or just holding it in your hand.
Examples
- Your phone lights up when you look at it, even if you’re not touching it.
- You're watching a video, and your phone knows exactly where you're focusing on the screen.
- When you're typing, your phone can tell if you're looking down or away.
