Inertial motion capture technology
Inertial Motion Capture is an non-optical system, this technology is based on miniature inertial sensors, biomechanical models and sensor fusion algorithms.

The motion data of the inertial sensors is often transmitted wirelessly to a computer, where the motion is recorded or viewed. Most inertial systems use gyroscopes to measure rotational rates. These rotations are translated to a skeleton in the software. Much like optical markers, the more gyros the more natural the data. No external cameras, emitters or markers are needed for relative motions. Inertial mocap systems capture the full six degrees of freedom body motion of a human in real-time.
