Microsoft’s Kinect [...] can make some educated guess about the age of gamers who are standing and put that information to good use.
Playing around with upcoming Xbox 360 Kinect game Joyride I asked the developers about playing the game with friends and children. They told me that the game can tell, based on the skeletal anatomy of a gamer, if they are children and then automatically adjust the difficulty.
That sounds like an awesome feature to me! What do you think? Will it have any trouble detecting short people you think? Or tall kids?
