Why Natal Is a Big Deal
Kikizo has an editorial piece evaluating the Xbox 360's upcoming motion-control scheme, Project Natal, and discussing why it's a bigger step forward for interactive gaming than many people think. Quoting: "[Natal] accurately perceives players in 3D space, simultaneously tracking over 48 joints on your body, enabling it to accurately redraw your skeleton in real time as you move about. On a separate 'debug screen' in the closed-doors session, we could witness for ourselves the 'mind's eye' of Natal, visually showing how it completely understands where we are, how we're moving, where we are in 3D space, how far in front of my face my hand is, whatever. It can supposedly even track individual hand and finger movement when it switches into this more finely-tuned mode. ... There is a surprising feeling of tactility and iPhone-like fluidity and precision to the way Natal works." Another interesting bit of news about Natal is that Wii-hacker Johnny Chung Lee is part of the development team. We've discussed some of his creations in the past.

If this technology is as good as it sounds, this spells the end of the mouse.
Seriously, my mousepad could be a touchpad.
Would probably need a thimble to avoid friction burn though.
The project Natal is indeed different for an Eye tool of a wii mote. This is a depth sensing camera (you have a RGB image and an image with the distance to the camera). This camera is made by Primesense (you can check theirs patents), it works by projecting a grid (infrared so you can't see it). By analyzing the deformed pattern with a camera, the depth is computed.
Having the deep information is really useful because you get the 3d cloud of the user and with some math, you can guess where is the user and what he is doing. For example you can find the biggest cluster of point (the user). The mass center of these points will give you the position of the user (this is already enough to to a lot of thing).
But the technology is not perfect. It will never be a full replacement for motion capture because it's subject to occlusions and there are a lot of ambiguous cases so the system will always need to cheat.
Say you only got one arm? or One leg?
Will Natal still work correctly?
EA: Sports 2010
Requirements: Xbox 360, Natal system, no physical disabilites
What happens if I stand just behind my friend and it looks like we have four arms? Will Natal work that out?
Relying on cameras and sensors, the players are still stowed if something crosses between them and the sensors. At least with the Wii, if you see someone coming, you can raise the Wiimote or slide it to the side. If Natal is watching your whole body, and someone needs to cross in front of you to get to the bathroom (or if a large dog or smaller siblings come into the play space), you're stowed. Until they describe how they will compensate for environmental disruptions, I'll put this in the "useless hype" category.
I'm not saying the tech isn't cool, and I definately can see uses for it (the manipulation of 3D models alone would be awesome), but you're more likley to find uses for this in commerce and industry where dedicated manipulation zones can be established. Of course, it would also work if the game system is in someone's bedroom or another space where no one will bother the player, but those households are not going to be as broad an audience as that reached by the Wii. Hardcore gamers do have funds to spend, and I'm sure many will buy, but they will hit a market saturation point.
