The joystick has been the principal flight control in the cockpit of many aircraft, particularly military fast jets, where center stick or side-stick location may be employed. A popular variation of the joystick used on modern video game consoles is the analog stick. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling.
