1 Few things are more hyped （炒作） than the coming AI revolution. Billionaires fight over whether AI is going to save us or destroy us， and much of the future promise of AI is still years to come out. But when it comes to AI's application to body language， the future is already here. It's just not widely distributed yet.

2 How do computers read body language？ The short answer？ There isn't a short answer. Getting computers to understand human body language is no simple task. Let's break down the steps required for computers to get a good understanding of what your body language is saying.

3 First， the computer needs to see. So， it needs a camera. But a computer doesn't see like we do， and it only gets a stream of data from the camera. So， software first has to recognize the shape of a human body， and then map out the key points of our body. Some poor souls have to teach a computer what all of our different body parts look like in lots of different lighting conditions， and lots of different body types.

4 But understanding that an image contains an elbow， a knee， or a face doesn't do much good. So， now the computer is paying close attention to our faces and our hands. Classifying emotions as body language and facial expressions is literally in our genes， so it comes pretty easily.

5 But computers need to see a ton of examples of any kind of given body language， then to be told what that body language is or means， and then they can， over time， and with more and more examples， identify that same or similar stance with that emotion.

6 If I were a self⁃driving car approaching a crosswalk and I saw an upheld hand in front of me， I could infer the human wants me to stop as he/she intends to cross the street. If I instead saw that same human using the “move⁃along” gesture， that's a strong indication that he/she would prefer me to continue on my journey instead of waiting. A car has just read your body language.
