Understanding HumanTrak's 3D Reference System

In a system with as much under the hood as HumanTrak, it's sometimes difficult to know which way is up (and down, and left, and right...)

Here we'll run through the basics of what HumanTrak's reference planes and axes are, so you can better interpret what its data means.

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)
