"Imagine a small projector attached to your Android device, and you can use your hand and touch the projected image to navigate the UI through a Kinect attached to a PC. There's no need to just imagine it any longer, as the Android Kinect Projector Interface project is doing it now. The developers have built a system where a projector is attached to a Galaxy Nexus, and a Kinect attached to a PC running Simple-Kinect-Touch 2.0 communicates motion to control the running system. Using a custom AOSP ROM and TUIO for Android "touches" on the projected screen work just like touches on the physical screen would. "
I have the Kinect. I have the Nexus. I just don't have the skill. :-)
