Learn to Play Air Guitar
All of us have probably tried
to learn to play air guitar at least once. Now, some computer
scientists in Finland have come up with a device that turns
this rock fantasy into real music – an air guitar that really
plays.
Learn to Play Air Guitar like a
Superstar
The virtual guitar is the
invention of Aki Kinerva and other computer scientists from the
Helsinki University of Technology. All you need is a pair of
gloves and a camera. Then you take a rock star pose, like you
were holding a real guitar and just rock away.
The camera will be tracking
your hand movement along the imaginary fret board, as well as
the strumming of the other hand. Then the computer will receive
the information and turn the gestures into licks and riffs.
While you will probably not share the stage with Eric Clapton,
the system gives any of us a chance to feel like a rock
superstar.
Ever since rock music was
born, teenagers, as well as many adults all over the world have
been playing air guitar while listening to their favorite rock
bands on the stereo. Now, these computer scientists in Finland
have turned this habit into real music with an air guitar that
really makes some sounds.
How Does It
Work?
To make things even better,
the technology is almost entirely invisible. The gloves that
you have to wear are just a pair of normal orange gardening
gloves. As you are playing (or in my case, learn to play air
guitar), a web camera that is programmed to detect only the
orange color will watch your gloves and track their
movement.
In real time, software designed to recognize gestures will
translate your hand movement into sounds. When you will be
moving your hand down the fret board, the sound will go higher,
as if you were playing a real guitar. It really feels and
sounds as if you were actually playing.
What Can You Actually
Play?
Sure, you won't be able to do
all you can do on a real guitar. You won't be able to play
songs like “Stairway to Heaven” on an air guitar. However, if
it worked just like a real one, you would probably have to
spend months to learn to play air guitar. With an air guitar,
you get to feel like a rock guitarist within a few seconds. The
things you can do are limited though.
If you want to learn to play
air guitar with Kinerva's technology, there are two models you
can choose from: chord and solo mode. If you choose the chord
mode, you will only be able to play four different chords. This
is indeed limiting, but it's enough for playing the opening
chords of songs like “Smoke on the Water” and other rock
classics. With the solo mode, it will be as if you were running
up and down a pentatonic scale, which is the standard key of
rock guitar solos.
The best thing is that you
can't actually play it badly. No matter how you're moving your
hands and mixing chords and solo notes, it will sound like
you're playing something.
The whole system works on an
ordinary desktop computer. The inventors are now working on a
Windows version and air guitar may someday become as common as
Game cubes or X-boxes. Who knows, maybe it will even inspire
some people to sit down and learn to play a real
guitar.
