The Power Glove is a controller accessory for the Nintendo Entertainment System. The Power Glove itself was a commercial success for its early virtual reality mechanics and being shown in various forms of media. However, its games did not sell well, as it was not packaged with a game, and it was criticized for its imprecise and difficult-to-use controls. ==Development== The Power Glove was originally released in 1989.〔(【引用サイトリンク】title=A.G.E. Tech )〕 Though it was an officially licensed product, Nintendo was not involved in the design or release of this accessory. Rather, it was designed by Grant Goddard and Samuel Cooper Davis for Abrams/Gentile Entertainment (AGE), made by Mattel in the United States〔 and PAX in Japan. Additional development was accomplished through the efforts of Thomas G. Zimmerman and Jaron Lanier, a virtual reality pioneer responsible for co-developing and commercializing the DataGlove〔(Laparoscopic.MD - History of Robotic Surgery )〕 who had made a failed attempt at a similar design for Nintendo earlier. Mattel brought in Image Design and Marketing's Hal Berger and Gary Yamron to develop the raw technology into a functional product. They designed Power Glove over the course of eight weeks. 〔Hal Berger http://research.microsoft.com/en-us/um/people/bibuxton/buxtoncollection/a/pdf/powerglove%20design%20news%20%20article.pdf〕 〔(La Réalité Virtuelle - Chapitre 7 )〕 The Power Glove and DataGlove were based on Zimmerman's instrumented glove.〔See US Patent 4542291 (issued 1985): http://www.google.com/patents?vid=4542291〕 Zimmerman built the first prototype that demonstrated finger flex measurement and hand position tracking using a pair of ultrasonic transmitters. His original prototype used optical flex sensors to measure finger bending which were replaced with less expensive carbon-based flex sensors by the AGE team. 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「Power Glove」の詳細全文を読む スポンサード リンク
