More details of Nintendo's revolutionary Wii controller have come to light after developer notes were leaked recently. Nintendo has always been secretive about the technology behind the Wii-mote and has promised more revelations before the console's fall release, but this latest info has made the picture a little clearer.
The Wii-mote will be powered by two AA batteries, which will allow for 30-60 hours of game time, depending on which functions are used. Bluetooth wireless technology is used to communicate with the console, and the sensor bar that picks up the Wii-mote's movement is almost eight inches long, has a sensor at each end and must be placed above or below the TV. Also, players will need to calibrate the Wii-mote before play, marking these two sensors as coordinates in order to prevent interference from light sources and mirrors.
The controller will also featurea small amountof "non-volatile" memory, meaning that it'll retain information even when powered off, like a memory card. It seems that gamers could well be able to store a gamer-specific button configuration, although other possible uses haven't been specified.
