In computing, DirectInput is a legacy [1] Microsoft API for collecting input from a computer user, via input devices such as the mouse, keyboard, or a gamepad.It also provides a system for action mapping, which allows the user to assign specific actions within a game to the buttons and axes of the input devices.
A DI unit (direct input or direct inject) is an electronic device typically used in recording studios and in sound reinforcement systems to connect a high output impedance unbalanced output signal to a low-impedance, microphone level, balanced input, usually via an XLR connector and XLR cable.
A common computer input device, a keyboard. A user presses a key which transfers information to a computer. In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system, such as a computer or information appliance.
A pointing device is a human interface device that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. Graphical user interfaces (GUI) and CAD systems allow the user to control and provide data to the computer using physical gestures by moving a hand-held mouse or similar device across the surface of the ...
An alternative method is via instruction-based I/O which requires that a CPU have specialized instructions for I/O. [1] Both input and output devices have a data processing rate that can vary greatly. [2] With some devices able to exchange data at very high speeds direct access to memory (DMA) without the continuous aid of a CPU is required. [2]
Direct voice input (DVI), sometimes called voice input control (VIC), is a style of human–machine interaction "HMI" in which the user makes voice commands to issue instructions to the machine through speech recognition.

Less-sophisticated designs similar to those on remote controls appear on some calculators, particularly scientific and graphing calculators, which use the D-pad for cursor control on multi-line screens, as well as input/output recall, menu navigation, and occasionally direct screen access (graphing calculators in particular allow the use of the ...
