There is a growing need for more intuitive motion-based user interfaces in the highly competitive gaming and interactive 3D remote control market. Current motion sensing technologies, made popular by the success of the Nintendo Wii™ and Apple iPhone™, are based on 3-axis accelerometers that provide basic tilt, portrait versus landscape orientation, and linear motion tracking. Six-axis motion processing adds three axes of rotational movement information from gyroscopes with three axes of linear motion data from accelerometers to deliver high precision 3D motion tracking that is responsive to every move, including gesture recognition. For example, the Wii MotionPlus™ accessory tracks players’ movements with greater accuracy where even the slightest twist of the wrist or turn of the body is replicated exactly on the television screen.

So now Nintendo has their own '6 axis'???
Well I guess now we know the difference.....
