It's surprising to think that the Wii has been on sale for nearly four years, and we're only now seeing true competition from Nintendo's rivals. Of course, considering the half-hearted motion controls of the Sixaxis, it's probably wise for Sony to have been cooking PlayStation Move slowly since its introduction 15 months ago. The PlayStation's motion controller sticks much closer to the Wii's mould than Microsoft's Kinect , with E3's Move tagline being "This changes everything". Hyperbole aside, Sony is aiming to take the technological high road, as it does with all things PS3, and beat the Wii on precision and movement accuracy. The technology used is actually pretty similar to Nintendo's, but on steroids. The Wii's sensor bar sits by the TV and gives out infrared lights that a camera in the remote picks up in order for the pointer to function. Move flips this around, with a camera next to the TV picking up the glowing ball on the end of the controller. The PS3 can then measure distance from the controller using the size of the ball as a reference.
