Here’s a really cool USB Data Gloves. I am not sure what you can use it for, but here’s the link to instructions on how to make one.
This is the reconstruction of a “Fakespace GL-8001” device with fully compatible serial interface via USB. This device fits into a very small SubD adapter housing, consumes low power (max. 20 mA), supports USB standby, may support a USB remote wakeup feature later, is much faster in responsiveness than the GL-8001, and the electronic components are fairly cheap, lower than 5 €.
