During my talk at DD9 a couple of weeks ago, I discussed various different approaches to Domotics (that the posh word for home automation;-)). One of those ideas I suggested was to make use of Microsofts excellent Kinect and its depth perception cameras.
Great minds think alike, obviously, as I notice an entry on 123kinect.com showing exactly that!
Channel4 news ran a promotion on some of the stuff Microsoft are doing in Redmond, and beside the computer guided cars, theres a tour of the Microsoft house, where everything is controlled by touch, voice and gesture.
You can watch the video for yourself here.
Very very cool!
