Researchers say they have found a way to detect and recognise human gestures based on how they affect wi-fi signals.
They suggest it could let users control home appliances with a wave of the hand while in any room of the house.
They say the WiSee system offers a "simpler, cheaper" alternative to Microsoft's camera-based Kinect and other specialist gesture sensors.

For a moment I thought Nintendo were involved lol. I can't see the Kinect ever really becoming the preferred way of gaming , just as I can't for the life of me imagine sat waving my arms around to interact with my kettle, unless my the finished coffee can float to me on wifi signals too. Wiiwillsee.
