What happens if you take Nintendo's Wii remote and nunchuck and paint them black, streamline the controllers, and cut the tail? You get Sony's PlayStation Move motion controller and sub-controller.
Instead of a sensor bar, the PlayStation Move platform relies on the PlayStation Eye camera to help "deliver an innovative and highly immersive experience." The camera purports to detect precise movement, angle, and even how far away the player is from the console.
As for the motion controller itself, it includes a three-axis gyroscope, a three-axis accelerometer, and a terrestrial magnetic field sensor, as well as a color-changing field sensor that the camera uses to track movement. According to Sony, this combination allows for both fast and subtle motion.
Kotaku has put together a handy list outlining the differences between the PlayStation Move and Nintendo's Wii remote (see here), including fewer buttons, "a smarter controller," and no wire between the motion- and sub-controller.
Sony says it will launch the new controllers worldwide this fall, but didn't offer up any pricing info.
