The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' <a href="/wiki/Decision-making" title="Decision-making">decision-making</a> process.

This generally means that the operator needs to provide minimal input to achieve the desired output, and also that the machine minimizes undesired outputs to the user. </p><p>User interfaces are composed of one or more layers, including a <b>human–machine interface</b> (<b>HMI</b>) that typically interfaces machines with physical <a href="/wiki/Input_device" title="Input device">input hardware</a> (such as keyboards, mice, or game pads) and output hardware (such as <a href="/wiki/Computer_monitor" title="Computer monitor">computer monitors</a>, speakers, and <a href="/wiki/Printer_(computing)" title="Printer (computing)">printers</a>). A device that implements an HMI is called a <a href="/wiki/Human_interface_device" title="Human interface device">human interface device</a> (HID). User interfaces that dispense with the physical movement of body parts as an intermediary step between the brain and the machine use no input or output devices except electrodes alone; they are called <a href="/wiki/Brain%E2%80%93computer_interface" title="Brain–computer interface">brain–computer interfaces</a> (BCIs) or <a href="/wiki/Brain%E2%80%93machine_interface" class="mw-redirect" title="Brain–machine interface">brain–machine interfaces</a> (BMIs). </p><p>Other terms for human–machine interfaces are <b>man–machine interface</b> (<b>MMI</b>) and, when the machine in question is a computer, <b>human–computer interface</b>. Additional UI layers may interact with one or more human senses, including: tactile UI (<a href="/wiki/Somatosensory_system" title="Somatosensory system">touch</a>), visual UI (<a href="/wiki/Visual_perception" title="Visual perception">sight</a>), auditory UI (<a href="/wiki/Hearing" title="Hearing">sound</a>), olfactory UI (<a href="/wiki/Olfaction" class="mw-redirect" title="Olfaction">smell</a>), equilibria UI (<a href="/wiki/Sense_of_balance" title="Sense of balance">balance</a>), and gustatory UI (<a href="/wiki/Taste" title="Taste">taste</a>). </p><p><b>Composite user interfaces</b> (<b>CUIs</b>) are UIs that interact with two or more senses. The most common CUI is a <i><a href="/wiki/Graphical_user_interface" title="Graphical user interface">graphical user interface</a></i> (GUI), which is composed of a tactile UI and a visual UI capable of displaying <a href="/wiki/Graphics" title="Graphics">graphics</a>. When sound is added to a GUI, it becomes a <i>multimedia user interface</i> (MUI). There are three broad categories of CUI: <i>standard</i>, <i>virtual</i> and <i>augmented</i>. Standard CUI use standard human interface devices like keyboards, mice, and computer monitors. When the CUI blocks out the real world to create a <a href="/wiki/Virtual_reality" title="Virtual reality">virtual reality</a>, the CUI is virtual and uses a <i>virtual reality interface</i>. When the CUI does not block out the real world and creates <a href="/wiki/Augmented_reality" title="Augmented reality">augmented reality</a>, the CUI is augmented and uses an <i>augmented reality interface</i>.

The program cards were not punched on the computer itself but on <a href="/wiki/Keypunch" title="Keypunch">keypunches</a>, specialized, typewriter-like machines that were notoriously bulky, unforgiving, and prone to mechanical failure.

The job would generate a printout, containing final results or an abort notice with an attached error log. Successful runs might also write a result on magnetic tape or generate some data cards to be used in a later computation. </p><p>The <a href="/wiki/Turnaround_time" title="Turnaround time">turnaround time</a> for a single job often spanned entire days. If one was very lucky, it might be hours; there was no real-time response.

The very earliest machines had to be partly rewired to incorporate program logic into themselves, using devices known as <a href="/wiki/Plugboard" title="Plugboard">plugboards</a>. </p><p>Early batch systems gave the currently running job the entire computer; program decks and tapes had to include what we would now think of as <a href="/wiki/Operating_system" title="Operating system">operating system</a> code to talk to I/O devices and do whatever other housekeeping was needed.

These used a <a href="/wiki/Resident_monitor" title="Resident monitor">monitor program</a> which was always resident on the computer. Programs could call the monitor for services. Another function of the monitor was to do better error checking on submitted jobs, catching errors earlier and more intelligently and generating more useful feedback to the users.

Teleprinters had originally been invented as devices for automatic telegraph transmission and reception; they had a history going back to 1902 and had already become well-established in newsrooms and elsewhere by 1920. In reusing them, economy was certainly a consideration, but psychology and the <a href="/wiki/Principle_of_least_astonishment" title="Principle of least astonishment">rule of least surprise</a> mattered as well; teleprinters provided a point of interface with the system that was familiar to many engineers and users. </p> <figure class="mw-default-size mw-halign-left" typeof="mw:File/Thumb"><a href="/wiki/File:DEC_VT100_terminal.jpg" class="mw-file-description"><img alt="The VT100, introduced in 197″8, was the most popular VDT of all time.

These cut latency further, because characters could be thrown on the phosphor dots of a screen more quickly than a printer head or carriage can move. They helped quell conservative resistance to interactive programming by cutting ink and paper consumables out of the cost picture, and were to the first TV generation of the late 1950s and 60s even more iconic and comfortable than teleprinters had been to the computer pioneers of the 1940s. </p><p>Just as importantly, the existence of an accessible screen—a two-dimensional display of text that could be rapidly and reversibly modified—made it economical for software designers to deploy interfaces that could be described as visual rather than textual. The pioneering applications of this kind were computer games and text editors; close descendants of some of the earliest specimens, such as <a href="/wiki/Rogue_(video_game)" title="Rogue (video game)">rogue</a>(6), and <a href="/wiki/Vi_(text_editor)" title="Vi (text editor)">vi</a>(1), are still a live part of <a href="/wiki/Unix" title="Unix">Unix</a> tradition. </p> <div class="mw-heading mw-heading3"><h3 id="1985:_SAA_user_interface_or_text-based_user_interface">1985: SAA user interface or text-based user interface</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=User_interface&action=edit&section=6" title="Edit section: 1985: SAA user interface or text-based user interface"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In 1985, with the beginning of <a href="/wiki/Microsoft_Windows" title="Microsoft Windows">Microsoft Windows</a> and other <a href="/wiki/Graphical_user_interface" title="Graphical user interface">graphical user interfaces</a>, IBM created what is called the <a href="/wiki/IBM_Systems_Application_Architecture" title="IBM Systems Application Architecture">Systems Application Architecture</a> (SAA) standard which include the <a href="/wiki/IBM_Common_User_Access" title="IBM Common User Access">Common User Access</a> (CUA) derivative.
