Watch | X-Ray vision could now be a reality

X-ray vision has been a comic book fantasy for decades but now it is all set to become a reality. Graduate students in the Massachusetts Institute of Technology have developed a software that uses variations in radio signals to recognize human silhouettes through walls. The device basically tracks people with wireless signals. It recognizes motion and can also identify a person. The technology will help health care providers and families keep closer tabs on young or elderly. It is also expected to be of great benefit in hostage situations.
