power-glove-to-mac.txt (which originates in early 1992) discusses how to connect a Mattel Power Glove™ to a Macintosh ADB (Apple Desktop Bus) port.
Even more curious was Transfinite Systems and their “Gold Brick,” the converter that made it possible to connect game controllers and consoles to Macs. Most clever was their plan to bootstrap (not unlike Playpower):
By designing it to work with inexpensive and commercially available controllers, Transfinite is using an existing market to create a potentially new one. The first applications of Gold Brick will no doubt be ports of Nintendo games or even communications between the game deck and the Mac through Gold Brick.
Rotating a 3D solid with a Power Glove should be a lot easier than doing the same thing with the mouse. After that, our imagination is the limit for new methods of controlling virtual objects. Gold Brick’s sub-title is “The Cyberspace Interface” […] One way or another, Gold Brick sounds like it might help introduce the next generation of controllers.
And then there’s this from Compute magazine #133:
At the Speech-Language Pathology Lab at northeastern University, experimenters Linda Farrier and Harriet Fell are using a Mac, a Gold Brick, and a Power Pad to develop a system called the Baby Babble Blanket, which allows speech-disabled babies to make meaningful sounds and initiate verable interactions. The Mac issues digitized sounds—babbling or any other noise, including words—according to how and where the baby moves around on the Power Pad. Farrier says the system could also be used as a biofeedback device for adults in physical therapy.
