This device is Sony’s response to Nintendo’s Wiimote. It does not suffer the same limitations as the wiimote for a couple of reasons. First of, the PS3 is has far superior hardware than the Wii and the Wiimote detects motion with the help of an IR-referenspoint and an accelerometer. The Playstation Motion Controller (PMC) is simply a updated version of the Wiimote. It has a RGB, LED-lit sphere on the top. This sphere is used to track the motion in X and Y-axis but the size of the sphere also helps the system to simply calculate the Z-axis based on the size of the ball. It also includes an three-axis accelerometer that determains the tilt of the controller BUT also and three-axis gyrometer to help determain movement for when the sphere is blocked by the user. By combining these three technologys with the most advanced processor ever (the Cell) the Playstation can give a perfect 1:1 motion detection. Coupled with the RGB-sphere and the force-feedback technology this device is one of the best human-computer interaction devices to date.
