There’s only one thing worse than air guitarists and that’s people who make fun of air guitarists. It’s a hallowed tradition going back to Jagger, Bowie and Noddy Holder. And now it’s technically feasible, thanks to the Finns who have made air guitarists’ rock dreams come true:
The Virtual Air Guitar project, developed at the Helsinki University of Technology, adds genuine electric guitar sounds to the passionately played air guitar. Using a computer to monitor the hand movements of a “player”, the system adds riffs and licks to match frantic mid-air finger work. By responding instantly to a wide variety of gestures it promises to turn even the least musically gifted air guitarist to a virtual fret board virtuoso. […]
The resulting system consists of a video camera and a computer hooked up to an appropriately loud set of speakers. A player then needs only to don a pair of brightly coloured gloves in order to rock out. Computer vision software automatically keeps track of their hands and detects different gestures.
