What are direct input devices?
In computing, DirectInput is a legacy Microsoft API for collecting input from a computer user, via input devices such as the mouse, keyboard, or a gamepad. they enable an application to retrieve data from input devices even when the application is in the background.
What is direct and indirect input?
Indirect and direct input refers to how data or commands are entered into a system [Jacob, 1996]. Indirect devices translate some action of the human body into data. Direct devices have no intermediary; the movement of the body equals the input to the machine.
