===Optical===
One weakness of optical tracking is [[occlusion]]. Occlusion occurs when objects are hidden from the camera because they are behind other objects.
====Marker====
Optical tracking with mark consist of adding an unique marker onto an object you want to track. Then use a camera or multiple cameras to follow the movement and position of the marker. Finally algorithms are used to figure out the position and orientation of the object.
