Ai Live, LiveMove is apparently the application in the Wii SDK that allows designers to simply record their movements as input data for the Wii. Here's a video that demonstrates it.
Here is a video of the demonstration, and hot damn is that some cool shit. Of course, thinking about it after seeing it, I can't imagine another way to do it that seems even remotely practical. Why wold you do it any other way? Nonetheless, looks like the entire process of making games just got a lot more fun.
What I think is especially neat is that by designing the input parameters this way, the designer is forced to know from the get-go if the move feels the way he wants it to feel. It's pretty easy, even trivial, to shut your eyes, imagine frying and egg, fishing, or roping a calf with a lasso, and then perform the action in a way that just feels right.
Perhaps forcing designers to come at the experience design from this perspective - literally aping the players interactions to develop the games control scheme - is the genius element behind the Wii design.
