The V-Hand's purpose is to capture all hand and finger movements.
Out of order, but inserted here as reminder for myself: To increase accuracy, the next version of the V-Hand will have a 3-axis compass built in. This can be used to make sure rotation information from the gyroscopes doesn't drift. More or less, the V-Hand is an Inertial Navigation System without external references.
Basically, it's a glove with an Accelerometer, a Gyroscope and Potentiometers for tracking the fingers:
An Arduino Nano comes in handy to process all the data and send it to a PC:
The pictures above show the first prototype, which still uses breadboards. The second one, below, is already soldered:
That's how the sensor input looks like to the PC:
