An analogue stick, also known as a joystick or control stick, is an input device used for computer games and other applications. It consists of a horizontal stick that can be moved in any direction to provide two-dimensional movement on screen, similar to the way one would move a mouse cursor. The position of the stick determines the direction and speed of movement, while buttons on top or bottom of the stick allow for additional control. Analogue sticks are commonly used as game controllers for video games, providing more precise and natural movements than digital controls.
