Motus Darwin controller to bring that Wii feeling to the PC - Engadget
Based on an existing Motus golf club controller called the iClub (very original, guys), the Darwin tracks motion using gyroscopes, accelerometers and a compass, which allows it to track absolute motion without the need for a sensor bar like the Wiimote. Motus also says that the Darwin is more accurate and faster to relay motion data than the Wiimote, which allows games to more accurately simulate real world activities.
