X-ray vision software developed

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 healthcare 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.
