Wii Head Tracking

I don't know about that. For one, your example requires a mouse/keyboard, which requires sitting at a desk, which kind of defeats the whole purpose. Aiming with a WiiMote type controller would work though. But how would you turn? Implementing a 180 turn would be difficult, and with 1 2D screen I predict vomit.

True, what I described would remove the athletics from the device and restrict it only to a 3D display. I suppose for a more useful athletic workout in a FPS, you would have to have two remotes, one in each hand. One would be for aiming and shooting, while the other would be for movement. As a PC gamer, I also cringe at the thought of that setup, but to be honest I already cringe at the PS and XBox remotes. Still, even the 3D perspective alone would be a nice addition to a game if you could get it for $60! Turning is still usually supported in most FPS controls, and it wouldn't be too inconvenient, for instance Q & E in a WASD setup. You might also be able to do something where you hold down a single key and it puts the headset into turn mode rather than freelook mode. The game turns your character in whichever way you look. Then release the key to go back to freelook.

The Wii nunchucks would work well as you describe it - aim with one, turn controls on the other. I guess the main problem to solve for FPS games is the multiplicity of axis control. If moving up/back from the screen moves the game character, this must be married with forward/back controls, since the head tracking range is limited. The side to side movement would also be limited in range, and very confusing when married with a left/right rotation scheme.

As the guy described it in the video, head tracking is a way to look through a frame from different angles, the challenge now is to pair this with a way to move the frame around in space. I'm assuming this guy will have that solved in a couple weeks, he seems very dedicated.

Wiimotes on your feet...
I can already see motion capturing with Wiimotes.
But then I also see a small problem because the Wiimote has a forward-looking camera which has to be pointed at the sensor bar if I'm not mistaken, that would mean if you turn it too far into one direction, it will lose track of the sensor bar and thus you'd lose control. This problem would increase the closer the Wiimote is to the sensor bar and if I'm not mistaken, that's why the Track IR has such a sensor "bow" or array so it can cover a wider angle and thus find the infrared lights in a wider angle which should be useful if you're sitting close to it at a desk. Don't they recommend using the Wiimote 2m away from the screen anyway?

Also next up, infrared-guided missiles using a Wiimote.
