Sony's latest addition to the PlayStation, Move, has been torn apart by iFixIt. They discovered it's about as "complex as a mobile phone, but without the radio chip".
They did find some interesting things inside though - apart from the magic used to make it work:
"The Wii and PlayStation use different methods of locating their controllers. The Wii Remote has an infrared (IR) sensor built into the controller, and uses triangulation from the IR emitters on the sensor bar placed near the TV to locate itself. PlayStation Move, unlike the Wii, can locate the motion controller in 3D space. The PlayStation Eye camera visually recognizes the X/Y position as well as the relative size of the glowing sphere on the motion controller to pinpoint the controller's location.
The Move contains many of components found in today's smartphones: a processor, accelerometer, gyroscope, Bluetooth transmitter, vibrating motor, and even a MEMS compass. It's an amazing amount of tech for the money, even though we still think it's steep to pay $50 for a controller. Compared to a $40 WiiMote, though, it's quite the bang for the buck."
Is it just me, or is tech sexier when in pieces?
