Kinect requires a camera-and-microphone accessory called the Kinect Sensor that is placed by the television and console. It can tell where a player is in a room as well as differentiate between different voices. A camera in the device takes pictures of the users while they’re playing a game, while a depth sensor helps track the movements of body parts.
The result is an experience that removes the need for physical controllers. In a car-racing game, for example, a player just has to form the shape of a wheel with their hands and turn it in either direction to navigate. In a track and field game, players can run in place to compete in a race, or jump to go over a hurdle.
