Researchers at the University of Washington have come up with a rather clever way of controlling your home appliances using standard WiFi signals and gestures. The technology, called WiSee, works by detecting minute changes in wireless signals when there’s movement in a room, and by using a custom router they have managed to identify specific gestures reliably enough to trigger pre-defined actions.

You may have thought that throwing all this technology at the humble mobile phone was getting ridiculous, but you’ve really not seen anything yet. Not only are these people expecting us to use them as wallets, citizen arrest cameras and to monitor earthquakes, but now they’re actually expecting that we’ll throw our car keys away and phone our way into the driving seat.
