The Wii's sensor bar coupled with the Wii Remote allows the game to sense acceleration and to determine where the player is pointing. The Wii Remote senses light projected from the bar, contrary to what a standard light gun can perform. Five LED lights are positioned on both sides of the sensor bar, with a total of ten in all. Because of the viewing angle of the Wii Remote, being too far away from the sensor bar will result in a disruption and possibly disconnection. A cordless sensor bar is also available for purchase.
