Free software, a webcam, and some stickers printed on an inkjet can turn any object into a real-world controller. That’s what Paul Rose of Institut Fatima and his team did with a soccer ball (translation for the civilized world: football). The software is powered by the same framework used for the reacTable, but in this case there’s no table and no projector: just a ball.

Institut FATIMA uses a Fussball as (des-)controller for triggering drumsamples. The camera detects the symbols on the ball, kicks numbers into the sequencer, the sequencer matches goals. The goal is always music. Software used is reactivision and ableton live. Do it at home.

As it happens, reacTIVision just got a significant update, with more improvements planned. You can read up on the full details on Create Digital Motion:

Free Tangible Tracking: reacTIVision 1.4 Here, TUIO2 Coming Soon

Martin Kaltenbrunner, co-creator of the framework (and the reacTable), has some tips for working with tangible interfaces and music, and where to find more inspiration.

In addition to TUIO, reacTIVision also has an alternative MIDI mode, where you can map the appearance of fiducial symbols to note ON and OFF events, as well as their X,Y and rotation angle to a control channel value. Quite a few people have been using this for the creation of cheap web-cam based MIDI controllers.

Using TUIO, you have more alternatives though, you can currently use Max/MSP, Pure Data, Quartz Composer, Processing, Java, C++, C# and so on to receive the object & finger tracking data. Here are a few cool musical projects, that have been built using reacTIVision:

Patrick H. Lauke (patch pictured, from Flickr) has a video on YouTube that shows some of the basic workflow for combining the free patching environment Pd with TUIO and reacTIVision. He cautions:

this may not be pleasant from a musical point of view, but it only serves as a first test for further experimentation.

Hopefully this gives folks some ammunition if you’re getting involved in the tangible interface hackday! [Project site | on CDMu]

NAMM supposedly stands for the “National Association of Music Manufacturers.” It’s purportedly a trade show for music instruments and technology. But, for brief but glorious moments, “NAMM show” translates in English to “ridiculous musical stuff.” Just how ridiculous? We’re talking guitars made out of football helmets.

Just in case you think you might extract any respectability from this $299 novelty guitar, there’s more: interchangeable face masks. Multiple colors for matching your favorite team (you’ll have to provide the logos — guess they didn’t pony up for a license). A built-in speaker, just in case an amp looks too, you know, professional. And the pièce de résistance, football-shaped guitar picks.

Helmet Guitars

Any pride left? Well, how about filming a demo video playing this,(inexplicably) shirtless. Hint: do not tell, say, potential dates or job interviews “Last night, I took off my shirt and started totally wailing on my helmet guitar!” That could be interpreted in way too many ways, none of them not wrong.

Hey, at least Miesel Stringed Instruments doesn’t have any illusions. They promise the guitar “will have you rockin’ all the way from your rec room at home, college dorm, tailgate party, to the Super Bowl after party!”

Will you see anything this fun at CES? I don’t think so.

But if I sound in any way critical, it’s only because I think the Helmet Guitar can’t begin to compare with the same builder’s aquarium acoustic guitar (among others).

Tune in January 17-20 for live coverage from the NAMM show in Los Angeles, from the awesome to the awesomely strange. And stock up on donuts, because you may start craving them.
