1. A method of tracking a movement of an object in 3D space, the method comprising: capturing a plurality of temporally sequential images of the object within the 3D space; defining a detection zone in the 3D space, the detection zone including at least a portion of the object; computationally analyzing the images to determine movement parameters associated with the object portion movement within the detection zone; and computationally scaling the movement parameters to generate normalized parameters relative to the detection zone.
