posted this in an earlier thread were the op was wanting to know the differences.

ps eye:

  • augmented reality which includes
    • gender recognition
    • facial recognition
    • age recognition
    • object recognition (patented well everyday items are patented)
    • facial expression recognition (patented well laughter is patented) 
  • head tracking
  • there is a mic but it's primary purpose was to help detect the position of the user, in my experience it isn't good at voice recognition, although that could be down to the software aswell
  • movement detection

there is more I'm just not thinking of it at the moment. oh and most of the augmented stuff is from what sony says is in its vision library with the exception of eyepet very few games use them.

natal (based on what MS has told us)

  • augmented reality from what I have seen they also have a pretty descent library although they haven't demonstrated or shown age recognition. I don't see any reason why they can't do it though the facial expression and use of everyday items are patent protect so unless there is away round it. it includes gesture recognition something I am yet to see from the eye. (although move will likely do this)
  • 3d depth tracking
  • full body tracking
  • mic, primarily designed as a command interface
  • one step up from the eye's movement detection instead of using the pixels, alone to determine movement, it will apparently use a ir bar to help detect movement in a given distance.
  • area you have to be in will adjust depending on the size of the room.
  • built in processor to do the calculations, freeing up the 360, processor. (it a chip called prime sense made and named after the company behind natal)
  • some motor things for tilting the camera and for fast zoom 

again there is more probably a lot more with natal but this is just of the top of my head.

You need to take the processor one out of there.  MS has already announced removal of the processor due to price concerns.  The calculations are now done by the 360, which is said will take up 15% of its processing power.  The truth is, we haven't really seen Natal's 3-D tracking ability in any game situation.  Ricochet was just side to side.  On top of that, we haven't seen any videos of the performance of Natal sans processor

There was news a while ago that Natal does still have a processor actually.  Whether the processor is little more than a controller for the software or whether its a full hardware accelerator wasn't made clear but there is most definately a processor based off the latest news we have.  I'm pretty sure we have seen a prototype of a "processorless" model in one of the many videos shown, albeit it just running Ricochet.  Ricochet does do full 3D tracking as it works out how hard you hit a ball based on the motion it captures.

The OP is badly worded and ill informed hence the accusations of flame bait from other users.  The actual game doesn't really appeal to me in the slightest.
