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 two 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.
The Power Glove was originally released in 1989. 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 codeveloping and commercializing the DataGlove 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. 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. (Full article...)
