If consoles go motion control standard next-gen, why are you going PC?

Head tracking devices can be use to track the hand  as a mouse is a hand tracking device. Thus take Johnny video but instead of using glasses with IR lights just put the IR bar in your hand and Bingo it now tracks your hand without having to aim at the camera. (Unlike the wand you still have to make sure the IR lights is facing the camera)

*shakes head*

You realize that has nothing to do with being accurate right? It's just as accurate in your hand or on your TV... Head tracking helps make the illusion of images popping out of the screen and not a whole lot else.

As far as real accuracy the more points of reference the IR camera has the easier it is to track position.  The sensor bar has 2 points of reference so the IR camera can tell when you're turning upside down, it can also tell how far away the camera is by tracking those two points in reference to the camera. 

On the other hand the PS wand has one IR ball on the top of the wand, the PS eye can track where that is, but its using software to "fake" tracking in a 3D space, basically it tracks it by seeing the item in reference getting bigger (getting closer) and smaller (going away).  It doesn't truly know, if a baloon was deflating in front of it it would think it was moving away.  On top of that there was a head tracking tech demo made for the PS eye, it worked well but not as precise as the head tracking demo Johnny made.

From my understanding PS wand doesn't have a IR ball. Also 2 points of reference can't tell you when you upside down yet it can tell you turning your wii remote. What Johnny was very careful not to show you was if he turn his head slightly toward to left or right of the screen it would zoom out and lean right or left instead of changing the view to the  right or left. That's because it only has two reference points so it can't track 6d movement.

 The reason you can be more accurate with movement the  IR points instead of the camera is exact like you can be more accurate putting a camcorder on a stand and turn the person in view around rather than keeping the person in video still and you walk around the person with the camcorder in hand.

 As far as tracking 6D movement the wand uses motion detection with the ball tracking. (that's the problem with wii-mote it's hard to use both motion detection and IR tracking at the same time since you got to aim with the wii-mote) Just how well this works we have to wait and see.

The giant glowy ball that's right on top of the Wand that is hard to miss >_>  that's an IR ball.

And with 2 points of reference you can tell when something is turning upside down...

You brought up one issue, the Wii remote does need to be pointed in the light sources general direction (about 45 degrees in any direction from the front of the remote) the ball also has the issue of something obstructing it's view if it be a person or you're turning it backwards, if the camera can't see it, it can't accurately tell where it is in that space just it'll just go by the general difference in movement much like the Wii remote.

As for the camcorder and the stand thing, that's a crock, its tracking movement, no matter which part of the set up of the setup is moving it's gonna track it as long as it's in range, so thats a pretty bad analogy.  The main differences you're going to get is that the person with the Wii remote can sit there and barely move their wrist to move the pointer, which works very well for FPS and TPS games, while the wand users could accurately have the controllers position mapped out in real time, that means while the pointer controls are looser you can do things like write your name and, dare I say it, have 1:1 sword fighting controls which would be better for things like Zelda and NMH. (note Wii Sports Resort has shown you can do it on Wii but you do have to point the Wii remote towards the screen from time to time)

On the other hand Nintendos solution is a bit more versitile, its funny you brought up some of the work Johnny did. While Sony basically needs the PS Eye to be the IR camera and the lightball on the remote to be the sensor, the Wii remote could just as easily be placed on top of the TV and Nintendo could sell a remote with Wii motion plus all added in except it also has a light sensor on top, therefore making it just like the PS wand with the exception that it had ports that you can expand the controller and actually get analog movement without having to hold a dual shock in one hand and a wand in the other.
