 This is Scientific American's Sixty Seconds Science. I am K.H., this will just take a minute.

Thanks to WiFi, we can watch movies, play games and check email from the comfort of the couch. And soon we may be able to repurpose our WiFi signal so we can turn on the coffee maker1 or turn off the TV with a simple flick2 of a finger from anywhere in the house. Researcher described their perspective system called the YC at the international conference on mobile computing3 and networking. The idea is similar in the concept to the Xbox connect which uses cameras to recognize a game player's movements and translate them into an action on screen . But YC works without cameras. Instead it uses the ambient wireless4 signals put out by our smart phones, laptops, routers and tablets. When we move, we altered the patterns of these WiFi signals. The YC receiver detects those disturbances5 and interprets the motion that cause them. Like waving or swinging your wrists. Of 900 gestures tested YC could identify 94%. The user signs are particular motion to a specific gadget6. The motion doesn't have to be the one that works in the real world. So if all goes well, you may actually be able to punch your lights out. 
Thanks for the minute for Scientific American's Sixty Seconds Science. I am K.H..
