How Does Eye-Tracking Tech Could Make Your Phone's Touchscreen Obsolete Work?

Eye-tracking tech could make your phone’s touchscreen obsolete by letting you use your eyes instead of your fingers to control your phone.

Imagine you're playing a game on your phone, but instead of tapping the screen with your finger, you just look at what you want to choose. That's how eye-tracking works, it follows where your eyes go and knows what you’re trying to do.

Your phone has special sensors that watch your eyes like a friend who always knows which toy you want to play with. When you look at the "Play" button, the phone sees your eyes move there, just like when you point at something and say, "That is my favorite!"

Right now, you have to tap on your screen, like pressing a big, soft button. But with eye-tracking, all you need to do is look. It’s like having a phone that listens to your eyes instead of waiting for you to press it.

So one day, your phone might be more like a magical friend who knows what you want, just by watching where your eyes go!
