MotionPlus
MotionPlus is a Nintendo peripheral for the Nintendo Wii that expands the console’s motion sensing by adding a gyroscope to the Wii Remote. The accessory attaches to the end of the Wii Remote and provides three-axis rotational data (pitch, yaw, and roll) in addition to the remote’s built-in accelerometer. This enables more precise and fluid interpretation of player movements, particularly for swordplay, fencing, and other gesture-based inputs.
Technically, MotionPlus supplies gyroscopic data to the Wii and works in conjunction with compatible software. Games
MotionPlus was announced and released during the Wii era as a separate add-on that could be purchased
