Based on our +15 years experience in the field, we developed our own algorithms for a motion capture that is totally free from magnetometer solutions but that can still provide tens of minutes of continuous recording.
We call this MAG-FREE TECHNOLOGY*.
From a practical perspective, this means to run full body motion capture with the following advantages:
no need to calibrate magnetometer at each recording session (there aren't any)
no limitation in the type environment where motion capture can be carried out:
laboratory
home
pysiotherapic office
no limitation in the scenario of application:
gait analysis with cables under the ground
force plates
prosthetic devices or metallic orthopedic tools
ferromagnetic objects in the environment
