AI technology uses radio signals to 'see through walls'

Researchers have built an AI-powered camera with the power to'see' through walls. The system uses radio frequencies to sense movement, allowing it to'watch' people walk, jump and sit – even when they are obscured from view. While the camera could allow anyone to spy on you, researchers are hoping it will prove useful in healthcare applications. It could, for instance, be used in care homes to monitor if someone has taken a fall behind closed doors. MIT researchers have developed AI that can see through walls (pictured).
