In the future, robots we will be able to read your body language. There are already a bunch of research teams working to make robots smarter in this area. Researchers at Carnegie Mellon University have developed a system that understands hand gestures and body movements in real-time. It can also track multiple people.
The solution was developed using a two-story dome embedded with 500 video cameras. Robots that understand body language will be able to better serve in social spaces.
