You Can Have X-Ray Vision For Only $300

If you could have one superhero power what would it be? I always I wished I could be invisible...for obvious reasons! How about X-ray vision? Well, now you can.

X-ray vision has been little more than a comic book fantasy-- well, until now! 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.

The device displays the signal on a screen, where the person's movements can be tracked in real time. It depicts the target as a red dot moving around the room, occupying a chair and speeding up or slowing down. The wireless signals used to track a person's motions also can measure the individual's breathing and heart rate -- and potentially identify the person based on the shape of his or her skeleton.
