Okay, this isn't going to be easy, but a developer has posted a video on YouTube showing how it's possible to use an Android handset, a projector, a Kinect and a computer to create the future. In your living room. Now.
In the video, he shows how, by hooking his Galaxy Nexus up to a PC, projector and Kinect, he can use simple gestures on the wall to control the handset. That is pretty freakin' awesome. As you might expect, though, it's not particularly straightforward.
In fact, he had to compile a custom Android ROM from the Android Open Source Project source code for the job. That was needed to let the PC feed the phone information about gestures, which themselves have to be translated on the PC when they arrive from the Kinect. So, as I say, it really is very involved. But it works, and it is frankly incredible. [DDRBoxman via Phandroid via MAKE]
