Some new details on the Wii got me thinking about some possible uses for the Wii as a training device. Will it be accurate enough to train and improve:

• Your tennis swing?
• Your dart throwing motion?
• Your fencing skills?
• Your ninja skills?

I don’t know! Iaido, what is happening in the video above, is a martial art that is meditative and full of dicipline. Lawyers and Doctors study non-grappling Iaido to avoid showing bruises in their regular life. Nothing like holding a 20″ razor to make you concentrate.

So will the Wii give us a dumbed-down plasticky version of this? In house dicipline? Yoga? I seriously doubt my own idea. After all, the DS with its writable screen hasn’t given us a cursive trainer.
