It's being regarded as the next major gaming interface but in my opinion Nintendo could really change the way we interact with our electronic devices.
For anyone who is not aware the time has come for the 3 big console manufactures to release their "next generation" gaming devices. Both Sony (releasing Playstation3) and Microsoft (released XBOX360) have gone the down the traditionally more powerful than the previous model path while Nintendo have done something completely different opting to develop a more "interactive" console experience to entice the consumer.
The whole focus of Nintendo's new console is the controller used to interface with the games. Unlike traditional gaming controllers which have buttons and miniature "joysticks" used to simulate movement, the remote (called the wiimote) it a step in a different direction.
Basically the remote looks similar to a normal TV remote with some traditional console buttons laid out on the top. however where it differs is that it is motion sensitive in a true 360 degree environment. Whilst in the past there have been some motion s sensitive devices they have limited to the up, down left and right motions.
What this means that by starting with the remote in a central position it can be moved in any direction (up, down, left, right, back, forth, tilted side to side, etc) and each movement can generate a response to the console.
So for example in a video game you could be playing tennis and use the remote as the racket handle to hit the ball, but depending on how you hold the remote you could twist it to spin, or lob the ball over your head. A smaller controller (also motion sensitive) is used in your right hand to control the movement of the player back and forth and so on.
While this is a basic summary of how the technology will be used it certainly open the door for interacting with other devices with the same technology.
In theory you could get rid of the mouse and use the controller to interact with a PC and a simple flick of the wrist would replace the current left/right click. People who have motor skill and muscle issues could find technology like this enables them to have easier access to devices where they may currently have limitations, or no access.
Currently this console is due to launch this year (no date confirmed as yet) so it will be interesting to see how well the technology works, and if it works as good as some early reports have verified it could be the start of a new way to interact with devices.
