An '''Input Device''' is often a one-way Man-Machine interface.

*Games controllers : Joysticks and joypads.

*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 User then analyses the displayed result and reacts again with another input from the device... We often call this having fun with a game.

Despite the ability from the computer to communicate with Users thanks to sound effects, this is a one way communication too.

But a sound input device can be implemented for a computer, even for an Amstrad...

Or those can also include fancy display units (scrrens) or whatever.
