Eric Clapton wannabes have strummed the classic riff from â€Layla†on imaginary Fenders for decades. Now, thanks to a virtual-reality rig developed at the Helsinki University of Technology in Finland, air guitarists can finally hear themselves jamming. The best part is that the machine can actually make them sound good.
To play, you simply put on a pair of bright orange gloves and start strumming. A webcam records your hand motions and relays the data to a PC.
