The Wii Balance Board is a balance board accessory for the Wii video game console.
It was introduced at the 2007 Electronic Entertainment Expo, along with the game Wii Fit.
It is compatible with both the Wii and the Wii U.
The board uses Bluetooth technology and contains four pressure sensors that are used to measure the user's center of balance—the location of the intersection between an imaginary line drawn vertically through the center of mass and the surface of the Balance Board—and weight. It runs on four AA batteries as a power source, which can power the board for about 60 hours.
It is noted in the manual that the Balance Board should only be used on a hard surface or thin carpet, as thicker or softer surfaces may cause the board to operate incorrectly. A set of foot extensions is included to allow the board to be used on softer surfaces, though the extension feet are not included in the European versions of the balance board.
