"I would think 3D optical recognition would be a lot easier than voice recognition."
It is. With cameras, all you have to do is track movement (changes from frame to frame). This is relatively simple for a computer to do. With voice recognition, you have to determine what wave is the word "a" or the expression "eh?", once you decipher that, you have to combine that with the sentence structure to try to figure out what the person wants to do.
I have a PS3 with the Eye Toy and when I showed it to my friends and family, they all loved it right away. Even though the games are a little wonky to control, they all wanted more. Motion capture is here today. The next step is making it 3D, and that's pretty simple with just 2 cameras facing 90 degrees from each other on one side of the room. Add another camera and it gets that much more precise. Though, this takes processing power.
