"controller"的定义和意义

What is a "controller"?

A controller is a device used to interact with video games, allowing players to control characters, actions, and other in-game elements. It can come in various forms, such as a gamepad, joystick, or steering wheel, depending on the type of game being played. Controllers typically feature buttons, triggers, and sticks that players use to input commands, with each button or action mapped to a specific function within the game. Controllers are commonly used with consoles and some PC games, providing a more immersive and intuitive gaming experience than a keyboard and mouse.
