This seems VERY interesting. I knew that since the Eye Toy can only pick up some body parts from the camera's point-of-view to appear on screen (remember the motion/camera thing that some science centers have for children to pretend they are doing the weather?; Chuck E. Cheeses has something like that as well, but like all motion/cameras, they need a special backlighting wall for a humanoid figure to show up on the screen in different environments, such as play areas etc.). Especially if the Eye Toy can track a certain object or pigment to display it on screen, this seems pretty neat, I'd say.
OH! But along with this new idea for Eye Toy, why not have an idea to actually track movement in a radius? Meaning, have censors placed in an area around the player (in a square formation) to track actual 3D movement. I've had that idea since I first heard the Wii had motion controls. Nintendo could do that (my idea of having a censor radius), so Sony better hurry up on that idea I just made! lol
