The joystick mechanism for Xbox One, Xbox One S, and Xbox Series X/S controllers (also known as an analog stick or thumbstick) is the component that allows player movement in the digital world, transmitting the user's physical movements to the console. The mechanism includes a rotary lever that can move in various directions, allowing control of the character or camera in games.

Its operation is based on two key elements: the mechanical construction of the lever and the sensors integrated into its base. When the user moves the joystick, the sensors detect the movement and record it in digital form, so it can be reproduced on the game screen. Mechanisms of this type are often sensitive to wear, as repeated movements can cause deterioration over time.
