How the HumanTrak 3D reference system works

The HumanTrak system uses three orthogonal reference axes and anatomical planes to capture and analyse movements in a three-dimensional space.

The below images provide an explanation of how these work in reference to the human body.

Reference Axes

X-Axis Left + / Right -	Y-Axis Up + / Down -	Z-Axis Forward - / Backward +

Anatomical Planes

Transverse Plane Horizontal	Sagittal Plane Side	Coronal Plane Front
