When I posted the ads for Mattel I mentioned the Power Glove and will repeat that summary here. The Power Glove is worn like a glove, hence the name, and contains a D-Pad, standard NES gamepad buttons, programmable buttons, and motion control functionality. Two games, Super Glove Ball and Bad Street Brawler, were made specifically for the controller, though those games can also be played with a regular gamepad minus extra features only usable with the Power Glove. U-Force is quite different from the Power Glove as players move their hands in front of the device without the need to hold anything. There is an accessory that can attach to the U-Force screen and be gripped to make simulation games, such as flight and driving games, easier to control. Both debuted in 1989 with a $10 price differential; the U-Force was $69.95 and the Power Glove cost $79.95.
I've got a variety of articles though none of the magazines appear to have officially reviewed the hardware. I am also including a review for Super Glove Ball which is the primary game designed for the Power Glove.
