Input device

As input devices, all devices are referred to, over the computer information may be supplied, so that interaction is possible with the computer programs. Input devices for computer or console games will specifically use are often referred to as a game controller or game controller. Some input devices are also called Human Interface Device (HID ). Special input devices come in professional emulation scenarios for use, for example, constructed for training purposes simulators, in recording studios or editing suites. Here, the specific controls are simulated realistically, however, serve only to enter parameters for a software.

In information technology a logical device Console is defined, through which the streams were read in the manufacturing processes. The console receives the data from the input device.

The counterpart of the input devices are output devices that make the results of an operation or an application, the outside world accessible.

History

The technical devices for entering have changed over time. At the initial time input signals were generated by means of switches, made ​​later by relay circuits that generated signals. The punch card has long been the classic input medium of the evolving data processing. The punched card reader, the input device is available for this medium. Another medium of this time, the strip hole. In order to produce paper tape were typed the information on a keyboard, while a paper tape punch instrument produced the strip. This has been read by a tape reader. Only in the next step the keyboard to the data processing device is connected directly or indirectly. Thus, the keyboard became the classical input device.

Examples

Graphics Tablet

A graphics tablet is an input device specifically for drawing on the screen, which consists of a pad ( the tablet itself) and a pointing device - usually a pen ( stylus) or a mouse with a crosshair ( Puck ) - exists. The functionality is similar to a mouse, but is packaged for the behavior of a classical drawing tool and therefore has further possibilities, such as pressure or tilt sensitivity. In addition, the relative motion of the pointing device is not detected, but the exact position on the tablet, whereby the precise tracing a template is possible.
