So I built my own pair with 70% of the functionality for three orders of magnitude cheaper. These gloves will measure the position and movement of your fingers and dump it into a computer so you can teleoperate a robot, control animatronics, manipulate digital content, or whatever you want.
Step 1: The Glove
Step 2: Detecting movement
To use these pots, just use an ohmmeter to see which pins change resistance when you wiggle the joystick. Solder some long wires to the pins and put a little heatshrink over it to keep it from accidentally shorting. I used zip ties to keep the wires organized.
