What are depth sensing cameras?

A depth sensing camera is like a super-smart eye that can tell how far away things are.

Imagine you're playing hide and seek in your living room. A normal camera would just show you what’s going on, it knows what you see, but not how far away you are. But a depth sensing camera is like having a special ruler attached to your eye that tells you exactly how far each object is from you.

Think of it like this: when you look at something with just one eye, it’s hard to tell if it's close or far away. But when you use both eyes, you get a better sense of distance, that’s called stereo vision. A depth sensing camera does something similar by using multiple sensors or special light patterns to measure how far each object is.

These cameras are used in phones and robots so they can tell if someone is close or far away, like when your phone knows to unlock only when you're near it, just like a robot friend who knows exactly where you are!
