A joystick is a type of input device used to control an object or a set of objects in a two-dimensional or three-dimensional space. It consists of a stick mounted on a base that can be moved in various directions. The movement of the stick is translated into commands for the controlled object, such as a cursor on a screen or a character in a video game.

The basic design of a joystick involves a pivot point at the base of the stick, allowing it to tilt freely. Sensors within the base detect the angle and direction of the stick's movement. These sensors can be potentiometers, which vary electrical resistance based on position, or Hall effect sensors, which use magnetic fields to determine the stick's orientation. Many joysticks also include buttons on the base or on the stick itself, which can be used for additional commands like firing weapons or jumping.

Joysticks have a wide range of applications. They are commonly found in video game consoles and arcade machines, where they offer intuitive control for gameplay. Beyond gaming, joysticks are utilized in industrial machinery, flight simulators, remote-controlled vehicles, and assistive technology for individuals with mobility impairments. The versatility and direct control offered by joysticks make them a valuable tool for interacting with electronic systems.
