X-ray vision, a comic book fantasy for decades, is becoming a reality in a lab at MIT.

A group of researchers led by Massachusetts Institute of Technology professor Dina Katabi has developed software that uses variations in radio signals to recognize human silhouettes through walls and track their movements.

Researchers say the technology will be able to help health care providers and families keep closer tabs on toddlers and the elderly, and it could be a new strategic tool for law enforcement and the military.

“Think of it just like cameras, except that it’s not a camera,” said Fadel Adib, a researcher on the MIT team developing the device.

“It’s a sensor that can monitor people and allow you to control devices just by pointing at them,” he said.

Work began in 2012 to determine how wireless signals could be used to “see” what’s happening in another room, said Katabi, who directs the MIT Wireless Center.
