Scientists Create Air Guitar T-shirt

onco_p53 writes "Australian scientists have invented a T-shirt that allows air guitarists to play actual music as they strum the air. The shirt has sensors in each elbow and sleeves to detect and interpret the air guitarist's arm movements — one arm chooses chords and the other strums imaginary strings. The gestures are then connected wirelessly to guitar audio samples to generate the music. Check out the video!"

    I'll probably be modded as flamebait but I don't think that shirt was actually controlling that sound. I think this video was intended to be a viral internet video to garner venture capital for developing that kind of technology.

    I assume this is intended to only play power chords and on top of that there is no way the machine can determine if you intend the third to be major or minor in the chord. Which is interesting because in the video, the chord changes from major to minor with no change in the performer. That's fine, let's then assume that you can select a key and it will adhere to the chords in that key.

    At several points in the video, he strums by flicking his wrist instead of moving his whole arm. That's pretty standard for guitarists but doesn't explain how the shirt (with sensor fibres in the elbow) would recognize the motion. Also, near the end, the guitar that I assume he is playing strums multiple times without him doing anything.

    I read the article and, if it has been developed, this short short video did not do a good job of showing it off or selling me on it actually working. I'd rather see an average guy just messing around with it with no back track. I don't care if it's not perfect, it's just that I could make that video with crappy acid trip effects in my basement and my friend on guitar watching me move my arms.

      Grab your right elbow with your left hand, flick your left wrist. There is movement there, and it is different than when you movce your whole arm. It's possible to differentiate between the two I suspect, maybe not easy, but possible.

      From the video it seems he is "playing" only the most basic cords. Hes explanation of the shirt seems to indicate that the motion detected is only the most rudimentary. The cord select is based on the angle of one arm and the actual playing is based on the movement of the other arm. The positions of the arm (angle of the shoulder) doesn't matter because there is only a sensor in the elbow. Overall this seems to be more of a software experiment then anything else. A more interesting system might have electrodes in the sleeves to detect muscle movement. Through signal processing it may be possible to actually determine the movements of the wrist and fingers.

      You're lucky. Atleast you can form cords. Due to a few very stupid injuries to my hands and fingers when I was younger, and when I was not quite so younger (Like when I got my hand stuck between the bowl and the mixer of a Hobart, that is, a dough-mixing machine, when I worked at a pizza joint, and broke some bones in my hand,) I have a very difficult time co-ordinating motions with multiple fingers. Things like typing, or playing single-notes quickly on a guitar are easy, as long as the fingers are moved individually. But when I have to move three or four fingers in a highly complicated manner extremely quickly, in unison, like switching chords, I still have a great deal of trouble, even after an extensive ammount of practice.

      I can still make chords. It just takes a rather lot of practice, and I still will fail to do it correctly when the change has to be even slightly quick. For example, the progression of Smoke on the Water's main riff, which for simplicity I'll say is open, third fret, fifth, open, third, six, fifth, is hard for me to do. The quick, small change from holding down on the six to holding down on the fifth is something I consistently fuck up quite often, no matter how many hours of practice I put in.

      Of course, I do have alot of other motor-control related dificulties, mainly from brain damage (Yeah, kids. Let me tell you something. The Society for Creative Anachronism looks like a good idea when you're stoned/tripping/robocoping, but being repeatedly knocked out by big burly scotsmen, or, rather, people who are pretending to be scotsmen, leads to brain damage. At present I'm recovering from my 13th concussion. There had been jokes about it due to the number), and therefore I'm not sure if I should blame it all on my fingers.

      As a side note, I can use a picture of my brain activity (I forget the name of the machine used to generate the picture,) to scare teenagers out of doing drugs.

      Not that I'd want to do that. They have to make their own mistakes, or they'll never mature.

    Alright - I realize this isn't a glove interface, but what is it with geeks, "virtual" environments (including those in the head), and air guitar? Arguably, from everything I have read about the history of VPL, the DataGlove's first raison-d'etra (probably munged that!) was so that Jaron Lanier (and a buddy?) could play "air guitar" using their Atari ST and MIDI (google around on "VPL" and "DataGlove" if you don't believe me). Since that time, tons of people, companies, and bands have experimented in one form or another to bring the "air guitar" to life.

    I don't play the guitar, nor do I know how, and I won't say I have strummed a bit in the air, too - everyone has, I think. However, I know that if I really wanted to play guitar, no amount of movements "in air" will ever be able to recreate what happens with a real guitar. At best, I will get an approximation of (likely) samples of somebody else's real performance.

    Finally, I must admit I haven't read the article - but I would be willing to bet that there are 50/50 odds that the article mentions how the technology could be used to "read" sign language by monitoring the movements of the arms (yet another thing the DataGlove was touted as a useful thing to do with it, and yet another that gets hauled out year-after-year).
