I only knew about this company while looking thru a volume of Boy's Life. The only product that this company has made so far is a glove for the NU64, and PSX. This glove differs from the PowerGlove released for use with the NES back in the 1980s. The one main difference is that the Power Glove is programmed while the glove that Reality Quest makes is not. Think of it as a one handed controller. This product only costs about $25, and I bought one the other day. You can visit The Glove Webpage if you want to. In it you'll find a bunch of testimonials, and explanations of how the glove works.
You control the movement on screen while moving your wrist (not your hand--yet another difference from the Power Glove) and the buttons are on top of the fingers (did I mention that the glove is just a model arm and hand??), to get in position stick your hand up through the bands on the back. Reality Quest did make a left-handed glove, but due to the fact that most stores thought that the glove would generate low sales (gee, sound familiar??) so they didn't market it.
