No, there has never been anything done like what I am talking about. Using your voice to interact with characters on the screen and solving puzzles with your fingers (close up to the TV) and using your hands to do things in game and using the cloud to update the voice recognition and emotions in the game.
All of this is possible with kinect and no a 2D camera can't do all of this in realtime using your body and fingers in 3D to interact with the game.
The PSeye is an upgraded web cam from the eyetoy and it can't see you in the dark and it can't see your body in 3D and it can't give you proper computer vision that is why you need a 3D camera.
This isn't seaman for the Dreamcast, this is entirely different and innovative and yes it would be game that is interactive and you help the virtual person through the game.
