The primary component of PlayStation Move, the PlayStation Move motion controller (CECH-ZCM1E) is a wand controller which allows the user to interact with the console through motion and position in front of a PlayStation camera.[1] The PlayStation Move motion controller features an orb at the head which can glow in any of a full range of colors using RGB light-emitting diodes (LEDs).[16] Based on the colors in the user environment captured by the camera, the system dynamically selects an orb color that can be distinguished from the rest of the scene. The colored light serves as an active marker, the position of which can be tracked along the image plane by the camera.[17][18] The uniform spherical shape and known size of the light also allows the system to simply determine the controller's distance from the camera through the light's image size, thus enabling the controller's position to be tracked in three dimensions[18][19] with high precision and accuracy.[fn 1] The simple sphere-based distance calculation allows the controller to operate with minimal processing latency,[22] as opposed to other camera-based control techniques on the PlayStation 3.[23][fn 2]
