The joystick is mainly used for playing computer games. A joystick is a handheld device that allows users to control the movement of an object on a screen, such as a character in a game. The joystick usually has a stick that can be moved in different directions and buttons that can be pressed to perform different actions. Joysticks are popular among gamers because they provide a more immersive and intuitive way to interact with games than using a keyboard or mouse. While joysticks can also be used for other purposes, such as controlling airplanes or robotics, their primary use is for gaming.
