Controller class
Arrow key: The key used to control the direction when playing the game, the common arrow key in the gamepad is mainly "four direction" cross key and "eight direction" cross key two.
Small joystick: can rotate 360 degrees, first appeared on the controller of SONY's PlayStation game console, perfect for fighting games. But it's very different from a joystick.
Function keys: Function keys (buttons) and direction keys are the most important buttons of the handle, the current function keys of the handle have four keys, six keys and eight keys or even more, and the function keys are basically programmable (redefined).
Shooting key: Shooting key (commonly known as "trigger" in Hong Kong and Taiwan) and L/R key, designed at the top of the gamepad, for shooting games.
Vibration switch: Some gamepads with vibration function have a vibration effect button, but different brands of gamepads have different vibration buttons, such as: Logitech Power feedback Shield is marked as Rumble, some gamepads are marked as Shock.
Joystick class
Force feedback joystick: During the game, the situation encountered by the game protagonist can be transferred to the joystick in a simulated way, and the vibration and swing way to let the player have a real feeling.
Grip: That is, where the hand grip is held, the current high-end joysticks will be designed into an ergonomic shape to reduce the user's sense of fatigue.
Aircraft handle
Throttle valve: A device used in flight simulation games to control the throttle. There are many forms of throttle valves, such as roller type and push-pull rod type. Now some high-end gamepads are also designed with throttle devices, in order to support more advanced games.
Rudder: can be used to control aircraft and other directions, is a very important design of the joystick. At present, the style of the rudder is strange, some look like a throttle valve, and it is understood that the rudder is used.
Coolie cap: Some media are also called view switch (ViewSwitch). It is mainly used in some simulation games to switch perspectives.
Buttons: Used to achieve fire, search for enemy aircraft and other actions, the current high-end joysticks will have six or more buttons to adapt to increasingly complex flight simulation games.
Firing key: The firing key (commonly known as "trigger" in Hong Kong and Taiwan) is used to control the cannon or launch the missile function key, and can be customized (programmable).
Steering wheel
Steering wheel: The most important part of a racing game. There is usually a red button on the front of the steering wheel, which is used to set shortcuts during the game, and a row of paddle-shaped toggle switches on each side under the steering wheel, which are used to shift gears in car games.
Force feedback steering wheel: When playing a simulated racing game, the steering wheel will be communicated to the player by the vibration of the steering wheel according to the road conditions and the collision situation of the car, making the game more real.
Foot pedals: there are two pedals respectively play the role of accelerator and brake, and now some high-end steering wheels are also glued to the four corners of the foot pedal.
