Microsoft's Kinect motion sensor is the next step in video game controllers. In fact, it could mark the beginning of the end for traditional game controllers. Rather than being a device the user holds to press buttons that control the game, the Kinect removes the whole idea of buttons from the equation. It is a game changer. Instead of having players hold a controller, Kinect turns the player's body into the game controller, relying on an array of sensors to read a person's position and movements. Kinect takes the gamer off the couch and into the game. When purchasing a Kinect motion sensor, buyers should have a basic knowledge of Kinect and how and where to buy the items needed to facilitate this unique gaming experience.
