Is NATAL really any different than play station eye ?

[IIXShogunXII]

The PS eye puts your hands or body into the game and the movements on screen influence objects. Natal makes the character in the game move like you move. It does not merely put a video image of you on screen, but it mimics full body movement from head to toe into a character or object itself. It has voice recognition and facial recognition. It can sense emotions on your face ie when you are sad, angry happy etc. It enables a new form of Artificial intilligence (AI) that can fully interact with the player, like that Milo rubbish.
