The Wii MotionPlus (Japanese: Wiiモーションプラス) serves as an add-on device for the Wii Remote, the primary gaming controller for the Wii, enabling the interpretation of more intricate motions than the Wii Remote can achieve independently.
It made its initial debut in June 2009 and is compatible with both the Wii and its successor, the Wii U, for various games. Subsequently, a revised version of the Wii Remote, known as the Wii Remote Plus, was introduced, incorporating the Wii MotionPlus technology.
Nintendo officially announced the Wii MotionPlus through a press release on July 14, 2008, unveiling it the following day during a press conference at the E3 Media & Business Summit. On May 3, 2010, Nintendo disclosed that, starting from May 9, 2010, new consoles would include the Wii Sports Resort game and MotionPlus controller without a price increase.
Collaborating with the game development tool company AiLive, Nintendo developed the Wii MotionPlus, utilizing an InvenSense IDG-600 or IDG-650 sensor in later units, adhering to Nintendo's specifications. The idea for the Wii MotionPlus emerged shortly after completing the initial design of the Wii Remote, addressing developers' demand for more advanced motion sensing capabilities.
In a 2010 Nintendo Conference, the Wii Remote Plus was introduced, incorporating the MotionPlus functionality into a standard-sized Wii remote. Between June and August 2009, Club Nintendo in Japan organized a contest where members purchasing and registering a copy of Wii Sports Resort had a chance to win a sky blue Wii MotionPlus. In November 2009, a black Wii MotionPlus was launched coinciding with the release of the black Wii console.
The Wii MotionPlus accessory attaches to the end of the Wii Remote, in conjunction with the accelerometer and the sensor bar, providing more comprehensive tracking of a player's arm position.
