Seeing Through Walls- X-ray Vision is Becoming A Reality

X-Ray vision -- a comic book fantasy for decades -- is becoming a reality in a lab at MIT. The Massachusetts Institute of Technology 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 the young or elderly. They say 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.
