From: Arm movement speed assessment via a Kinect camera: A preliminary study in healthy subjects
Front and lateral view of a subject computed from the Kinect sensor data. This plot represents the middle of the motion and was traced using Python 2.7 and the plotting module Matplotlib 1.1.0 [12]. The instantaneous velocity is calculated using the x,y, and z coordinates shown in the figure. The green lines represent arms, red represents legs, and blue represents the torso.
