A joystick is a handheld input device used to control video games and computer graphics. It consists of a stick that pivots on a base, allowing users to move it in different directions. Joysticks are commonly found in arcade games, flight simulators, and gaming consoles, providing a more immersive experience. Joysticks work by translating the movement of the stick into signals that the computer or game console can understand. They often include buttons for additional functions, enhancing gameplay. Many modern joysticks also feature force feedback, which simulates the sensation of resistance, making the gaming experience more realistic.
