The is a balance board accessory for the Wii and Wii U video game consoles.〔"Wii Fit: How To Stay Balanced", ''GamePro'' 235 (April 2008): 19.〕 Along with Wii Fit,〔(【引用サイトリンク】title=Stay fit with Wii Balance Board )〕 it was introduced on July 11, 2007 at the Electronic Entertainment Expo. == Design == The Wii Balance Board is shaped like a household body scale, with a plain white top and light gray bottom. It runs on four AA batteries as a power source, which can power the board for about 60 hours. 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. In an interview conducted by gaming web site IGN, Shigeru Miyamoto stated that the Balance Board's ability to measure weight is probably more accurate than that of a typical bathroom scale. Although the Japanese packaging states that it is designed to support people weighing up to 136 kilograms (300 pounds) and the "Western" Balance Board up to 150 kg (330 pounds), they are actually the same board. The packaging differs due to regulatory differences between Japan and the United States. The sensors on the board can accurately measure up to 150 kg (330 pounds). The actual physical structure of the board can withstand much greater force equivalent to around 300 kg (660 pounds).〔Game Informer, Interview with Shigeru Miyamoto: (Different weight limits in different regions for Wii Balance Board )〕 Due to the similarities between the two products, the Wii Balance Board has been compared to the Joyboard, a peripheral released for the Atari VCS in 1982 by Amiga Corporation. The technology in the Joyboard was less advanced than that in the Wii Balance Board, with four directional switches instead of pressure sensors.〔 The manual says 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 available to allow the board to be used on softer surfaces. The extension feet are included with some versions of the Balance Board, but not in European versions. The balance board should be used with the players' bare feet; players who wear socks may not properly grip the hard surface, and can create a danger. Novelty ''Wii Fit'' non-skid socks, which use small rubber pads that stick to surfaces, were provided to members of Club Nintendo. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wii Balance Board」の詳細全文を読む スポンサード リンク
