1. A system configured for full-body tracking comprising:
at least one tracker, each of the at least one trackers hosts a joint sensor suite configured to track positions, orientations, and joint angles of a joint along a body, and each of the at least one trackers is configured to be attached to the body;
the joint sensor suite for each of the at least one trackers including:
a magnetic field sensor on a first limb of the joint and at least one magnet on at least one second limb of the joint;
an accelerometer; and
a gyroscope;
wherein, the joint sensor suite for each of the at least one trackers is configured to track acceleration, orientation, magnetic field strength, and magnetic field polarity of the joint along the body;
at least one wearable article, each of the at least one wearable articles is configured to enable one of the at least one trackers to be fastened to the joint along the body; and
a computational device configured to capture real-time user generated movements via each of the at least one trackers and digitize user poses and body positions.
