Wearable Motion Capture 91

AnonymousHack writes "Swiss and MIT researchers have developed a wearable kit that will capture your every move for mapping onto a virtual character. It's almost as accurate as the camera-based motion capture used in studios to develop games. The team have recorded people's movements in completely new locations — like driving a car — previously out of reach. There is even a video of it in action."

      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.

      Yes, you could, but it would also have to be relatively stationary for the standard mocap cameras to be able to pick up the motion of the driver inside. If the car is stationary, the person inside isn't moving naturally how one would move in a car. That's the idea here.

      "'The sensors are all off-the-shelf parts,' Adelsberger says, making the system much cheaper than other motion-capture technology. It cost about $3,000 currently, but this could come down to a few hundred dollars, he says, if the sensors are mass-produced."

  • 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
