Yeah, Noah's comments seem pretty apt to me. As far as exergaming is concerned, this stuff is right on the money.

I've been reading a bit about Japanese game development, and there is this big thing about how they conceptualize games from the "controller in," whereas we go from the "controller out." In other words, the Japanese spend a lot of time thinking about the control mechanism and what kind of games can be designed that really take full advantage of it. We're more likely to think of a game first and worry later about how it will be controlled. I think the Japanese way is vital for this new technology. Right now people are seeing only the obvious stuff that's been done before. However, someone who really put some thought into it could probably come up with some "killer app" type stuff that is straight out of left field--not dancing or exergaming, but something else that will make the rest of us go "d'oh! Why didn't I think of that??"

Heck, you would probably do best not even to go to gamers or devs for inspiration.

Hmm...Maybe it could be used for sign language?
