(Phys.org) —Forget to turn off the lights before leaving the apartment? No problem. Just raise your hand, finger-swipe the air, and your lights will power down. Want to change the song playing on your music system in the other room? Move your hand to the right and flip through the songs.The kicker? It does this using only Wi-Fi signals. There is no need for cameras or body sensors -- and you can use hand gestures to control things no matter where you are in your house. It's not like you have to remain in front of your computer to use it. And that means it's even better than the technology in "Minority Report". It almost seems like magic. The video included with the article is a bit boring but it will give you an idea of how it works.
The future's hurtling at us, and it's about time. Gimme!
