Like Kinect, these solutions will have a pair of 640 x 480 camera sensors to measure user position in 3D space, but don't expect them to have motorized tilt functionality or voice recognition -- PrimeSense said it won't be able to make those available for manufacturers, as they're all Microsoft ideas.
We don't know if we'd ever come to use tilt-zoom over the tried and tested pinch-to-zoom functionality -- which is naturally also present here -- but the Galaxy S II makes zooming of any kind a pleasure to behold.
