How Does Eye Tracking Work?

Eye tracking is like following a friend’s eyes to see what they're looking at, but done by a special gadget that understands where your eyes go.

Imagine you have a robot friend who can tell exactly where you’re looking, just by watching your eyes. That's how eye tracking works!

When you look at something, your eyes move, and the robot friend uses tiny lights or cameras to watch those movements.

Think of it like this: when you read a book, your eyes jump from word to word, kind of like a frog hopping on lily pads. The robot friend sees each hop and knows what page (or word) you're looking at.

Once the robot friend knows where you’re looking, it can tell a computer or another gadget what you saw. This helps computers understand your choices, like when you pick a game on a screen or choose a picture in a photo app.

It’s like having a super-smart helper who knows exactly what you're thinking just by watching your eyes! Eye tracking is like following a friend’s eyes to see what they're looking at, but done by a special gadget that understands where your eyes go.
