An Input Device is often a one-way Man-Machine interface.
Those mostly include :
- Games controllers : Joysticks and joypads.
- Pointing devices : Mouse, lightpens, Trackballs.
- Keyboard is also an input device.
- Lightguns are both a pointing device and a game controller.
The response from the machine often come from the Display (monitor) but also from the sound system.
The Human/User enter controls through the input devices, the Computer reacts and display a result (be it on screen or a sound effect or both), the Useranalyses the displayed result and reacts again with another input from the device... We call these Gaming.
Despite the ability from the computer to communicate with Users thanks to sound effect, this is a one way communication too.
Most computers actually can't hear the user's screaming against it when a software is getting frustrating or bug-riden.
Many modern versions of classical Gamecontrollers 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 modern controllers are a crossbreed between Lightpens/guns and joypads... in use.
