joystick

A joystick is a handle-like device that you use to control your character in a video game. If you want your character to move left, you generally move the joystick to the left.

Originally, a joystick was the control an airplane pilot uses to adjust the movements of the plane — by moving the joystick back and forth, the pilot adjusts the roll, and moving it up and down controls the pitch of the plane's nose. Joystick was aviators' slang for this lever, and the makers of the earliest video games, in the 1970s, adopted the word for their similarly-shaped control.
