      "Most Old" is more like it. His approach is new, but the VR community has had this working for a LONG time. As described in the book "VR Construction Kit" (probably out of print, I'm too lazy to check) positional gloves with finger sensors (e.g. The PowerGlove) were originally invented by a fellow who wanted an air guitar that would work. After a bit of finagling with the electronics, he came up with gloves containing Piezo-electric strips that could detect finger position. Thus the first "air guitar that works" was born. ;-)

      You know, this shouldn't be too hard to do. You could to write some software to simulate different types of concert crowds, at different levels of enthusiasm.

      You could, for instance, have it react to the signal from your electric guitar or microphone to fill in the quite moments of your jam session. You could also it produce a roar of recognition from a virtual crowd for whatever piece of shit you start practicing on your favorite instrument. Whenever you're finished, lots of more applause!!

      Something like this could be really, really funny! Your own little automatic, Hollywood applause machine. Hey, you could have it do laugh-tracks too, although this would be more difficult to trigger automatically.

  5. Slightly easier to build... by Darius+Jedburgh · · Score: 4, Interesting

    ...I just built myself a theremin based partly on this. It transmits a pair of RF signals at around 1MHz. As you move your hand around it varies the inductance of the coils so that the coils transmit at slightly different frequencies. As a result you get a signal at the average of the two frequencies modulated by the beat frequency. Tune an AM receiver to the average frequency and you get to listen to just the beats. It took a couple of hours to build. (The project I linked to above has an AM receiver built into the circuit but I didn't bother with that as I already had a spare radio.)

  16. Very interesting by WidescreenFreak · · Score: 3, Interesting

    As a musician and computer geek, I'm really fascinated by how they do this. There are so many nuances to guitar playing that it will be intriguing to see how they can pull this off.

    For example, does it analyze the angle/arc of the left hand to determine which strings are being stuck? That would suck to slightly arc your hand and suddenly you're playing the wrong string.

    How does it determine where your left hand is in relation to the position of the neck? There are various neck sizes, after all.

    The article implies that this is meant to simulate an electric guitar. With acoustic, you can strum on just about any position on the string and it will sound the same. With electric, the sound varies on the position due to the different pickups, each with its own tonal qualities, but each pickup is only an inch or so apart. Can this differentiate such minute details?

    Don't get me wrong. I'm not looking at this as an "all or nothing" deal like a lot of people do on Slashdot. Oh, well, it can't do everything so it's teh suck! This is a very interesting start. I'm pondering more for what its potential could be more than what it can do right now. The whole cliché of taking baby steps first comes to mind.

    Personally, I'd rather play the real thing. But at least this method could get people interested in guitar playing if they are too intimidated to buy a real one. And this won't result in painful calluses at the finger tips. :)

    Has anyone played that PS2 game: RockStar? This air guitar immediately reminded me of the game. In the game version, you actually hold a small, toy guitar that has 5 colored buttons on the neck. The screen then scrolls toward you indicating when and which colored buttons to hit. You also "strum" the strings by flipping what looks like a fat light-switch thing on the guitar. There is also an awesome wammy-bar for those deep dives.

    Then, in the background, you can see your selected guitar hero rocking out on stage. When you do good enough, you get a super-charger jolt from the guitar gods that signals you to physically "rock" the toy guitar into the upright position. Your guitar hero on-stage then spins the guitar and really jams out which makes the crowds go wild. Sounds childish and ego-centric? Yes. Easy? No. It's actually challenging and extremely addicting if you like playing guitar at all.

    I'd like to see this new air guitar technology be integrated in some similar way like this PS2 game is.
