Eye tracking

Have you ever noticed how your eyes move around when you look at something? Well, eye tracking is when we use special tools to follow and measure where the eyes move and focus.

To do this, we use something called an eye tracker, which can be a camera or sensor that watches and records where the eyes are looking. With this information, we can figure out things like where people look first when they see something, whether they skip over any parts, or even how long they look at something.

Eye tracking can be used in many different ways, like studying how people read or view advertisements. It's kind of like magic, because just by using our eyes to look at things, we can learn a lot about our brains and behavior!
