While waggling your Wii remote around provides a decent approximation of natural motion, Intel predicts a future where cameras will provide highly accurate motion data to a game system. "We imagine some future generation of [Nintendo's] Wii won't have hand controllers," Intel Chief Technology Officer Justin Rattner, told Business Week. "You just set up the cameras around the room and wave your hand like you're playing tennis."
It should be noted that there's nothing in the article to indicate that Rattner has any insider info on Nintendo's plans -- more than likely he was just theorizing about what he'd like to see in a future system. Still, the idea of a camera-based 3D motion-sensing setup has incredible potential for gaming. More than the simple video transposition of the Xbox Live Vision Camera or the PlayStation Eye, a multi-camera system could model your three-dimensional movements in real time, in effect placing a digital version of you in the game. The result could revolutionize the way we play games and even how they're made -- after all, why should developers use motion captured performances when the players can provide them for themselves?
Such a theoretical system would take quite a bit of processing power, though, which might explain why Intel is talking it up -- after all, they already have a chip that can perform one trillion calculations a second. The future's so bright, we're using our Wii remotes as makeshift shades.
