New details about the Wii controller have surfaced, thanks to IGN getting access to some official developer documentation. It has been previously known that the remote would utilize Bluetooth to communicate with the console and would be powered by two AA batteries. The remote will have an approximate battery life of 30 hours when used as a pointer. Accelerometer-only use will result in 60 hours of gameplay. Other new details include 6 KB of NVRAM, whose use is not documented in the official developer information. IGN theorizes that this may work with the integrated speaker, or could store custom settings. The 6 KB could also store Bluetooth pairing information for the remote.

The documentation also specifies the use of the buttons on the controller; IGN reports that all the buttons on the remote and the nunchuk attachment are digital. While gamers have known that halogen lamps could potentially interfere with the Wii controller, Nintendo also suggests that fluorescent lamps and mirrors could cause problems. Calibration should help reduce such interference greatly.

IGN also reports that the Wii acts somewhat as an eye, measuring coordinates on the X and Y axis. They speculate that this could mean that the controller could act as a camera. However, with the Wii-mote generally pointing away from the player, this doesn’t make a lot of sense. These co-ordinates will more likely act as a way for the developer to read where the remote is pointing on-screen. Further details can be found at IGN.
