How the Wiimote Works

The New York Times' 'How it Works' series touches on a remote with a twist: the Nintendo Wiimote. The article describes the micron-sized machines that make it work, displays cut-away graphics of the little white marvel, and rounds out the discussion with a breakdown of where the tech came from. From the article: "The controller's most-talked-about feature is the capacity to track its own relative motion. This enables players to do things like steer a car by twisting the remote in the air or moving a game character by tilting the remote down or up. 'This represents a fabulous example of the consumerization of MEMS,' the tiny devices known as micro-electro-mechanical systems, said Benedetto Vigna, general manager of the MEMS unit at STMicroelectronics, a leading maker of the accelerometers embedded in the controllers. (Nintendo itself declined to talk about the controllers' inner workings.) He said the motion sensors, using the technology that activates vehicle air bags, can accurately sense three axes of acceleration: up and down, left to right, and forward and backward."

  1. Analogies rule!!! by jibster · · Score: 5, Interesting

    These accelerometers are so sensitive, Mr. Vigna said, because electrons -- those subatomic particles that whirl around the nucleus of atoms like a video game in the making -- can sense the subtle atomic-level movement of the silicon structures. Even for /. that's a messed up analogy. How is an electron like a video game in the making? Or is it the whirling around the nucleus that resembles the video game creation process?

    Why would you want to have to calibrate it for the TV? The way it is set up right now, it is all relative. It doesn't have to aim exactly where you are pointing, it just has to change its position based on your movements in a consistent manner. The way it is now, i can go from a 23 inch TV to a 9 foot wide projector image with absolutely no calibration. Plug it in and go. That's really special.
