This video demonstrates the massively updated Processing sketch that I am now using to test the glove's sensors. It relies on serial data flow for everything and connects directly to the Arduino's virtual COM port, making it unsuitable for a finished product (you'd want a true HID-compatible connection). However, with this tool, you can very easily see everything about the glove's current condition to test things like touch sensitivity and mouse control.
The Processing sketch used here can be downloaded from the Keyglove repository. Visit keyglove.net/software for details.
