Nintendo has made the Wii Remote, a 3D remote used in playing computer games on its Nintendo's Wii game console. The Wii Remote contains sensors by which it is able to detect motion in 3D and know its position in 3D.
The typical computer mosue only moves on a 2D surface controlling a pointer on a 2D screen. Wii Remote opens the door for wireless 3D controllers that can give users a totally deeper experience. Operating systems in the future might offer a 3D interface with much richer functionality and ease of use than the 2D interfaces offered by the current popular operating systems.
