Face space

Face space is like a magic mirror that helps us understand how faces look different from each other. Imagine looking at yourself in the mirror with your friend standing next to you. Your face might be round, your friend's face might be long, and you both might have different eye shapes or nose sizes.

Now, imagine this mirror can take all these differences and turn them into a map of faces. This map puts all the faces in a special space where each face has its own unique place.

Face space helps scientists understand how our brains recognize faces, even when they're very different from each other. They can study how our brains process information about different facial features and how we use this information to recognize people we know.

So, in simple words, face space is like a magical map that helps people understand how faces look different from each other and how our brains recognize them.
