This Is The Future Of Video Games And Beyond

From BBC:
Lionhead Studios' Peter Molyneux has shown off a game character that recognises and responds to a player's mood.
The human interaction system is possible with Natal, a system being developed for the Xbox 360.
It monitors and reacts precisely to the player's movements and the way they talk.
Microsoft demonstrated Natal at the start of the E3 gaming conference in Los Angeles.
