I was fiddling with the calibration the other day and noticed that Kinect would put the little blue dot(denoting a point of interest,such as the head, hand, etc) on the controller when I was holding it with both hands. This would allow for players to do some motion based movements without letting go of the controller. Just moving your controller to the left and right could trigger your character to lean left or right(which might be more comfortable and less tiring than leaning). Just another possible ability to use with hybrid games.
