Ohjaussauvoja, commonly known as joysticks, are input devices used to control the movement of a character or object in a video game or other graphical interface. They typically consist of a base containing a lever or stick that can be moved in multiple directions. The movement of the stick is translated into signals that the connected device interprets as commands.

Early joysticks were often mechanical, relying on physical contact points to detect the position of the lever. Modern joysticks are usually electronic, using potentiometers or Hall effect sensors to accurately measure the stick's position and provide analog input. Many joysticks also feature additional buttons, triggers, or hats (small directional switches) that can be programmed for various in-game actions, expanding their functionality beyond simple directional control.

Joysticks are particularly popular in flight simulators and racing games, where the precise and continuous control they offer is beneficial. They can also be found in arcade games and are sometimes used for controlling machinery or robotic arms. The design and complexity of joysticks vary greatly, from simple, inexpensive models to sophisticated, multi-axis controllers with haptic feedback. The term "joystick" itself is believed to have originated from early aviation, referring to the control stick used by pilots.
