==what What are those?==
*Games controllers : Joysticks and joypads.
*Lightguns are both a pointing device and a game controller.
It is also to notice that many measurement devices are technically Input Devices this may include:
*Picture Scanners
*Audio Samplers
*Digital multimeter/oscilloscope
But for the purpose of simplicity this category will only include Man-Machine control devices.
==How does it work ?==
==And now?==
Many modern versions of Game Controllers are actually also output devices, as the Machine may control some features like lights, force or vibrator and so on.
Also it is to notice that some modern controllers are a crossbreed between Lightpens/guns and joypads... in use.
Or those can also include fancy display units (scrrensscreens) or whatever.
