Soon you too can have 'X-ray vision' for just $300

It may not be ready for gift-giving this year, but come 2017 this could be the hottest item on wish lists around the world: a $300 device that enables "X-ray vision." The technology has been under development for more than two years, and now a group of researchers from MIT's Computer Science and Artificial Intelligence Lab (CSAIL) is spinning off a company to market it. Dubbed RF Capture, the technology senses wireless reflections off the human body and can thereby "see" the silhouette of a human standing behind a wall. From across a building, it can determine where you are, who you are, and even which hand you're moving. Through a spin-off called Emerald, the plan is reportedly for it to hit the market in early 2017 at a price between $250 and $300.
