      I think this thing could be huge to professional sports.

      You could use this set up to help show athletes how to improve their form, be it in the weight room, on the golf course, ski slope, or any other place where repetitive precision movement is needed and a refinement of form could improve performance.

      Heck, even just as a trainer, get your clients to strap this thing on a couple of times (especially those who aren't keen on working out in front of a mirror) to show them their form and how to improve it.

      Or combine this with pre-defined motion capture to attempt to train the wearer on how to re-enact the original motions (be it real dancing, DDR, or even 'Ninja Challenge' or what ever that Spike show is!)

      For $3k and dropping, the entry fee is so low that there are sure to be people looking make a profit off this system. I'm interested to see what all they come up with :)

      • "I think this thing could be huge to professional sports." Good idea. But combine this with computer controlled feedback. Write a realtime golf swig analysis program that can produce a sound where the pitch varies depending on the amount of error in the swing. If you legs move wrong you hear one sound if the shoulders aren't right you hear aanother. Pracic untill you can make the noises go away. Could work for quite a few sports. Gymnastics, baseball,....

        • The only thing that is currently stopping the world from being filled to the brim with animated pr0n, or general animated amateur productions, is that mo-cap is expensive; Lightwave, Vue, Poser all have the ability to import mocap data and do generally realistic images.
          If this is under $500, I'll get it, and a few thousand others will also, for personal animation hobbies. if it costs a little more than that, it probably won't make that big of an impact.

        I second this. I currently use cameras to improve my DDR form: I point the eyetoy at my feet so I can see them on the screen as I dance, and I videotape my dancing to study my feet after dancing (some are on yt). Comparing the motion captures described in the story between players would be a tremendous imp

        I wouldn't be too sure about that, none of the console manufacturers even allow AO games. We're quite a ways off from pr0n video games.

        Be that as it may, haven't you noticed people buying the platform for the game? If AO games are only on PC, then the players will play on PCs.

        I remember reading about people doing cyber-sex via text. I have Apple ][ magazines (Softalk, iirc) with pr0n and AO games advertised within. Can't see these people not embracing this their Wearable Motion Capture-suited overlords, can you?

  • Motion capture by inertial navigation seems a bit expensive, but it's probably affordable for Swiss. Those IDG300's actually increased in price since they came out. Now we're finding all kinds of new uses for inertial navigation. Too bad there aren't many jobs for inertial navigation experts in Web 2.0 crazed Silicon Valley.

    This very product has been on the market for years, by Intersense, which also uses accelerometers augmented with ultrasound to prevent drift. It looks like MIT just copied them.

    This isn't really new.

    • My thoughts exactly.
    • yeah, but at $3k for components (without any economy of scale) this is just waiting to be turned into the next videogame peripheral... think of DDR, or Wii Fit or any sports game.. or any game really given how much mileage Nintendo's gotten out of it's nunchucks..
    • <sarcasm>Come on, that was in the last millennium; nobody reads papers from the last millennium anymore, in particular not if they're from the same university. Besides, that's just a product; I mean, products aren't science, are they?</sarcasm>
      • Read the website more carefully. They make an off-the-shelf product that combines intertial measurement with ultrasonic sensors to correct for drift. It's the exact same technique. Intersense may or may not make a "suit" but you can bet people who've bought the intersense products sure have.

    Everyday, I bike along a company called Xsense [xsense.com] here in Enschede, the Netherlands, which is selling a similar system called Moven [moven.com] as described here as a commercial product.

    • Sorry, for the incorrect link, it is www.xsens.com [xsens.com]. There system is much more wearable and you can even capture things like brake dancing.

      • you can even capture things like brake dancing.
        I see quite enough of /that/ every time I get onto the highway.

      • you can even capture things like brake dancing.
        Ahh, you really are from the Netherlands aren't you? Brake dancing? Is that like drifting, but you get to see how the driver hits the pedals with eminem on the radio? And my gosh, they do it on a highway?

        That will be all, thank you, more abuse at 11.
        • Okay, it should have been "break dancing". I felt that there was something funny about it when I wrote that, and me knowing that I am dyslectic should have made me think twice. I suppose your Dutch is as good as my English, as otherwise you would not have made fun of me.

    • Here's a video [youtube.com] of the moven suit. The discussion after it points out that their suit costs $60K USD.

      It's nice to see people going after the low-cost end that would make this kind of thing ubiquitous. Hopefully they won't be hindered by patents (Xsense has an unpublished patent application related to this).

  • If I had this prototype I'd be hacking Second Life to stream my movements into the world (and get Linden Labs to stream it out) and everyone would be like "wow, how's he move like that?!" but I guess they'd just think I was a poser.

      • There's also augmented reality. You could recreate your house in Second Life and wear this suit around with a head mounted display on. What would be really cool (and I've not seen anyone do this yet) is a full house CAVE system. Cover the walls of your house with OLED displays and wear LCD shutter glasses. You'd probably need a whole server farm to run it.

  • It seems like the motion that's captured remains in place, with the hips not getting the translation data, so if you were o capture a run, the 3d character would stay in the same spot. This might be useful for creating run cycles for games, but it would practically be useless for anything else, since it would take a long time for an animator to go in and make sure the feet placement is correct and the character isn't sliding around everywhere. Motion capture data is very heavy and fairly hard to adjust once
  • This same technology was on the business investment show "Dragons' Den" but invented by a British guy.
