Wii Remote is the main controller for Nintendo's Wii con- sole. Thanks to the use of accelerometer and optical sensor technology, it presents motion sensing capability, which implies gesture recognition and intuitive pointing. Such a controller is user-friendly, inexpensive and easily available, due to growing Wii console's popularity. These features make Wii Remote a good device to create and manipulate both music and audio in a home entertainment environment. In this paper, the most interesting characteristics of the controller will be reviewed. A case study will be presented, namely the creation of a virtual music instrument to be controlled in a collaborative way through a set of Wii Remotes.
