The user interface, in the industrial design field of human–machine interaction, is the space where interaction between humans and machines occurs. The goal of interaction between a human and a machine at the user interface is effective operation and control of the machine, and feedback from the machine which aids the operator in making operational decisions. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls, and process controls. The design considerations applicable when creating user interfaces are related to or involve such disciplines as ergonomics and psychology.

A user interface is the system by which people (users) interact with a machine. The user interface includes hardware (physical) and software (logical) components. User interfaces exist for various systems, and provide a means of:

• Input, allowing the users to manipulate a system
• Output, allowing the system to indicate the effects of the users' manipulation

Generally, the goal of human-machine interaction engineering is to produce a user interface which makes it easy, efficient, and enjoyable to operate a machine in the way which produces the desired result. 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 human.

Ever since the increased use of personal computers and the relative decline in societal awareness of heavy machinery, the term user interface has taken on overtones of the graphical user interface, while industrial control panel and machinery control design discussions more commonly refer to human-machine interfaces.

Other terms for user interface include human–computer interface (HCI) and man–machine interface (MMI).

Introduction[link]

To work with a system, users have to be able to control and assess the state of the system. For example, when driving an automobile, the driver uses the steering wheel to control the direction of the vehicle, and the accelerator pedal, brake pedal and gearstick to control the speed of the vehicle. The driver perceives the position of the vehicle by looking through the windshield and exact speed of the vehicle by reading the speedometer. The user interface of the automobile is on the whole composed of the instruments the driver can use to accomplish the tasks of driving and maintaining the automobile.

Terminology[link]

There is a difference between a user interface and an operator interface or a human–machine interface.

• The term "user interface" is often used in the context of (personal) computer systems and electronic devices
  • Where a network of equipment or computers are interlinked through an MES (Manufacturing Execution System)-or Host.
  • An HMI is typically local to one machine or piece of equipment, and is the interface method between the human and the equipment/machine. An Operator interface is the interface method by which multiple equipment that are linked by a host control system is accessed or controlled.^{[clarification needed]}
  • The system may expose several user interfaces to serve different kinds of users. For example, a computerized library database might provide two user interfaces, one for library patrons (limited set of functions, optimized for ease of use) and the other for library personnel (wide set of functions, optimized for efficiency).^{[clarification needed]}

• The user interface of a mechanical system, a vehicle or an industrial installation is sometimes referred to as the human–machine interface (HMI).^{[citation needed]} HMI is a modification of the original term MMI (man-machine interface).^{[citation needed]} In practice, the abbreviation MMI is still frequently used^{[citation needed]} although some^[who?] may claim that MMI stands for something different now. Another abbreviation is HCI, but is more commonly used for human-computer interaction.^{[citation needed]} Other terms used are operator interface console (OIC) and operator interface terminal (OIT).^{[citation needed]} However it is abbreviated, the terms refer to the 'layer' that separates a human that is operating a machine from the machine itself.^{[citation needed]}

In science fiction, HMI is sometimes used to refer to what is better described as direct neural interface. However, this latter usage is seeing increasing application in the real-life use of (medical) prostheses—the artificial extension that replaces a missing body part (e.g., cochlear implants).^{[citation needed]}

In some circumstance computers might observe the user, and react according to their actions without specific commands. A means of tracking parts of the body is required, and sensors noting the position of the head, direction of gaze and so on have been used experimentally. This is particularly relevant to immersive interfaces.^{[citation needed]}

Usability[link]

See also: mental model, human action cycle, usability testing, and ergonomics. List of human-computer interaction topics

User interfaces are considered by some authors to be a prime ingredient of Computer user satisfaction. 

The design of a user interface affects the amount of effort the user must expend to provide input for the system and to interpret the output of the system, and how much effort it takes to learn how to do this. Usability is the degree to which the design of a particular user interface takes into account the human psychology and physiology of the users, and makes the process of using the system effective, efficient and satisfying.

Usability is mainly a characteristic of the user interface, but is also associated with the functionalities of the product and the process to design it. It describes how well a product can be used for its intended purpose by its target users with efficiency, effectiveness, and satisfaction, also taking into account the requirements from its context of use.

User interfaces in computing[link]

In computer science and human-computer interaction, the user interface (of a computer program) refers to the graphical, textual and auditory information the program presents to the user, and the control sequences (such as keystrokes with the computer keyboard, movements of the computer mouse, and selections with the touchscreen) the user employs to control the program.

Types[link]

Direct manipulation interface is the name of a general class of user interfaces that allow users to manipulate objects presented to them, using actions that correspond at least loosely to the physical world.

Currently (as of 2009^[update]) the following types of user interface are the most common:

• Graphical user interfaces (GUI) accept input via devices such as computer keyboard and mouse and provide articulated graphical output on the computer monitor. There are at least two different principles widely used in GUI design: Object-oriented user interfaces (OOUIs) and application oriented interfaces^{[verification needed]}.
• Web-based user interfaces or web user interfaces (WUI) are a subclass of GUIs that accept input and provide output by generating web pages which are transmitted via the Internet and viewed by the user using a web browser program. Newer implementations utilize Java, AJAX, Adobe Flex, Microsoft .NET, or similar technologies to provide real-time control in a separate program, eliminating the need to refresh a traditional HTML based web browser. Administrative web interfaces for web-servers, servers and networked computers are often called control panels.
• Touchscreens are displays that accept input by touch of fingers or a stylus. Used in a growing amount of mobile devices and many types of point of sale, industrial processes and machines, self-service machines etc.

User interfaces that are common in various fields outside desktop computing:

• Command line interfaces, where the user provides the input by typing a command string with the computer keyboard and the system provides output by printing text on the computer monitor. Used by programmers and system administrators, in engineering and scientific environments, and by technically advanced personal computer users.

• Touch user interface are graphical user interfaces using a touchpad or touchscreen display as a combined input and output device. They supplement or replace other forms of output with haptic feedback methods. Used in computerized simulators etc.

Other types of user interfaces:

• Attentive user interfaces manage the user attention deciding when to interrupt the user, the kind of warnings, and the level of detail of the messages presented to the user.
• Batch interfaces are non-interactive user interfaces, where the user specifies all the details of the batch job in advance to batch processing, and receives the output when all the processing is done. The computer does not prompt for further input after the processing has started.
• Conversational Interface Agents attempt to personify the computer interface in the form of an animated person, robot, or other character (such as Microsoft's Clippy the paperclip), and present interactions in a conversational form.
• Crossing-based interfaces are graphical user interfaces in which the primary task consists in crossing boundaries instead of pointing.
• Gesture interfaces are graphical user interfaces which accept input in a form of hand gestures, or mouse gestures sketched with a computer mouse or a stylus.
• Intelligent user interfaces are human-machine interfaces that aim to improve the efficiency, effectiveness, and naturalness of human-machine interaction by representing, reasoning, and acting on models of the user, domain, task, discourse, and media (e.g., graphics, natural language, gesture).
• Motion tracking interfaces monitor the user's body motions and translate them into commands, currently being developed by Apple^[1]
• Multi-screen interfaces, employ multiple displays to provide a more flexible interaction. This is often employed in computer game interaction in both the commercial arcades and more recently the handheld markets.
• Noncommand user interfaces, which observe the user to infer his / her needs and intentions, without requiring that he / she formulate explicit commands.
• Object-oriented user interfaces (OOUI) are based on object-oriented programming metaphors, allowing users to manipulate simulated objects and their properties.
• Reflexive user interfaces where the users control and redefine the entire system via the user interface alone, for instance to change its command verbs. Typically this is only possible with very rich graphic user interfaces.
• Tangible user interfaces, which place a greater emphasis on touch and physical environment or its element.
• Task-Focused Interfaces are user interfaces which address the information overload problem of the desktop metaphor by making tasks, not files, the primary unit of interaction
• Text user interfaces are user interfaces which output text, but accept other form of input in addition to or in place of typed command strings.
• Voice user interfaces, which accept input and provide output by generating voice prompts. The user input is made by pressing keys or buttons, or responding verbally to the interface.
• Natural-Language interfaces - Used for search engines and on webpages. User types in a question and waits for a response.
• Zero-Input interfaces get inputs from a set of sensors instead of querying the user with input dialogs.
• Zooming user interfaces are graphical user interfaces in which information objects are represented at different levels of scale and detail, and where the user can change the scale of the viewed area in order to show more detail.

History[link]

The history of user interfaces can be divided into the following phases according to the dominant type of user interface:

• Batch interface, 1945–1968
• Command-line user interface, 1969 to present^{[citation needed]}
• Graphical user interface, 1981 to present — see History of the GUI for a detailed look^{[citation needed]}

Consistency[link]

This section needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (March 2011)

A property of a good user interface is consistency. Good user interface design is about getting a user to have a consistent set of expectations, and then meeting those expectations. Consistency can be bad if not used for a purpose and when it serves no benefit for the end user, though; like any other principle, consistency has its limits.^[2]

Consistency is one quality to trade off in user interface design as described by the cognitive dimensions framework. In some cases, a violation of consistency principles can provide sufficiently clear advantages that a wise and careful user interface designer may choose to violate consistency to achieve some other important goal.^[3]

There are three aspects identified as relevant to consistency.^{[4][dubious – discuss][not in citation given]}

First, the controls for different features should be presented in a consistent manner so that users can find the controls easily.^{[citation needed]} For example, users find it difficult to use software when some commands are available through menus, some through icons, some through right-clicks, some under a separate button at one corner of a screen, some grouped by function, some grouped by “common,” some grouped by “advanced.” A user looking for a command should have a consistent search strategy for finding it. The more search strategies a user has to use, the more frustrating the search will be. The more consistent the grouping, the easier the search. The principle of monotony of design in user interfaces states that ideally there should be only way to achieve a simple operation,^[5] to facilitate habituation to the interface.

Second, there is the "principle of least astonishment".^{[citation needed]} Various features should work in similar ways.^[6] For example, some features in Adobe Acrobat are "select tool, then select text to which apply." Others are "select text, then apply action to selection."^[7] Commands should work the same way in all contexts.

Third, consistency counsels against user interface changes version-to-version.^{[citation needed]} Change should be minimized, and forward-compatibility should be maintained. Generally, less mature software has fewer users who are entrenched in the status quo. Older, more broadly used software must more carefully hew to the status quo to avoid disruptive costs. For example, the change from the menu bars of Microsoft Office 2003 to the ribbon toolbar of Microsoft Office 2007 caused mixed reactions. The new interface caused rejection among advanced users,^[8] who reported losses in productivity,^[9] while average users reported improved productivity ^[8] and a fairly good acceptance.^[10] A usual solution in providing a new user interface is to provide a backwards-compatibility mode, so that a product's most intensive users are not forced to bear the costs of the change.^{[citation needed]} A second strategy is to introduce big changes in small increments, so that an overall redesign can be achieved without breaking consistency and providing user feedback at any single step.^[11]

Modalities and modes[link]

Two words are used in UI design to describe different ways in which a user can utilize a product. Modality refers to several alternate interfaces to the same product, while mode describes different states of the same interface.

A modality is a path of communication employed by the user interface to carry input and output. Examples of modalities:

• Input — computer keyboard allows the user to enter typed text, digitizing tablet allows the user to create free-form drawing
• Output — computer monitor allows the system to display text and graphics (vision modality), loudspeaker allows the system to produce sound (auditory modality)

The user interface may employ several redundant input modalities and output modalities, allowing the user to choose which ones to use for interaction.

A mode is a distinct method of operation within a computer program, in which the same input can produce different perceived results depending of the state of the computer program. For example, caps lock sets an input mode in which typed letters are uppercase by default; the same typing produces lowercase letters when not in caps lock mode. Heavy use of modes often reduces the usability of a user interface, as the user must expend effort to remember current mode states, and switch between mode states as necessary.

If they take the time to learn something, they expect to be able to apply that knowledge in many places. It follows that good designers conserve the number of things users need to learn to get stuff done. ... In rare cases, consistency can become a self-perpetuating monster: It has to be used for a purpose. A foolish consistency is one that serves no benefit for the end user. Making things look and work the same is pointless if the user can no longer accomplish their tasks. Rank making things useful above making them consistent. ... Consistency is great because people like predictable things. They will feel comfortable when they can rely on different parts of your product to do exactly what they think it will do."

Sony Computer Entertainment, Inc. is a major video game company specializing in a variety of areas in the video game industry, and is a wholly owned subsidiary and part of the Consumer Products & Services Group of Sony. The company was established on November 16, 1993 in Tokyo, Japan, prior to the launch of the original PlayStation video game system. Sony Computer Entertainment handles the research & development, production, and sales of both hardware and software for the PlayStation line of handheld and home console video game systems. It is also a developer and publisher of video game titles and is composed of several subsidiaries covering the company's biggest markets: North America, Europe and Asia.

History[link]

The North American operations, Sony Computer Entertainment of America, were established in May 1994 as a division of Sony Electronic Publishing.^[1] They were located in Foster City and headed by Steve Race. In the months prior to the release of PlayStation in Western markets, the operations were restructured: All videogame marketing from Sony Imagesoft was folded into SCEA in July 1995, with most affected employees transferred from Santa Monica to Foster City.^[2] On August 7, 1995, Steve Race unexpectedly resigned and was named CEO of Spectrum HoloByte three days later.^[2] He was replaced by Sony Electronics veteran Martin Homlish.^[2]

As part of a worldwide restructuring at the beginning of 1997, Sony Computer Entertainment America Inc. (currently Sony Computer Entertainment America LLC), headquartered in Foster City was reestablished as a wholly owned subsidiary of SCEI.^[3]

On July 1, 2002 Chairman of SCE, Shigeo Maruyama, was replaced by Tamotsu Iba as Chairman. Jack Tretton and Phil Harrison were also promoted to Senior Vice President of SCE.^[4]

On September 14, 2005, SCE formed Sony Computer Entertainment Worldwide Studios (SCE WWS),^[5] a single internal entity overseeing all wholly owned development studios within SCE. It is responsible for the creative and strategic direction of development and production of all computer entertainment software by all SCE-owned studios, all of which is produced exclusively for the PlayStation family of consoles. Shuhei Yoshida was named as President of SCE WWS on May 16, 2008,^[6] replacing Kazuo Hirai, who was serving interim after inaugural SCE WWS President Phil Harrison left the company in early 2008.^[7]

On November 30, 2006 President of SCE Ken Kutaragi was appointed as Chairman of SCE while Kazuo Hirai, President of SCEA was promoted to President of SCE.^[8] On April 26, 2007 Ken Kutaragi resigned from his position as Chairman of SCE and Group CEO passing on his duties to President of SCE, Kazuo Hirai.^[9]

On April 15, 2009 David Reeves President and CEO of SCE Europe announced that he would be resigning from his post. He had joined the company in 1995 and was appointed as Chairman of SCEE in 2003 and President in 2005.^[10] His role of President and CEO of SCEE would be taken over by Andrew House who joined Sony Corporation in 1990.^[11]

On December 8, 2005, video game developer Guerrilla Games, developers of the Killzone series, was acquired by Sony Computer Entertainment as part of its SCE WWS.^[12] On January 24, 2006 video game developer Zipper Interactive, developers of the SOCOM series, was acquired by Sony Computer Entertainment as part of its SCE WWS.^[13] On September 20, 2007 video game developers Evolution Studios and Bigbig Studios, developers of the MotorStorm series, were acquired by Sony Computer Entertainment as part of its SCE WWS.^[14]

On April 1, 2010 Sony Computer Entertainment was restructured to bring together Sony's mobile electronics and personal computers divisions. The main Japanese division of SCE was temporarily renamed to "SNE Platform Inc." (SNEP) on April 1, 2010 and split into two division focusing on different aspects namely "Sony Computer Entertainment Inc." consisting of a 1,300 employees which focus on the console business, and the network service business consisting of 60 to 70 employees. The network service business of SCE was absorbed into Sony Corp's Network Products & Service Group (NPSG) which has already been headed by Kaz Hirai since April 2009. The original Sony Computer Entertainment was then dissolved after the restructure.^[15][16][17] The North American and European branches of Sony Computer Entertainment was affected by the restructure and will remain as SCEA and SCEE. Sony Computer Entertainment CEO and Sony Corporation EVP, Kaz Hirai, is leading both departments.^[18]

On March 2, 2010 video game developer Media Molecule, developers of the PlayStation 3 game LittleBigPlanet, was acquired by Sony Computer Entertainment as part of its SCE WWS.^[19]

As of August 23, 2010, the headquarters of the company moved from Minami-Aoyama to the Sony City (Sony Corporation's headquarters) in Kōnan, Minato, Tokyo.^[20]

On April 20, 2011, Sony Computer Entertainment was the victim of an attack on its PlayStation Network system, which also affected its online division, Sony Online Entertainment.

On August 1, 2011, video game developer Sucker Punch Productions, developers of the Sly Cooper series and Infamous series, was also acquired.^[21]

Hardware[link]

Sony Computer Entertainment produces the PlayStation family of video game hardware consisting of consoles and handhelds. Sony's first wide home console release, the PlayStation (codenamed PSX during development, currently PSOne), was initially designed to be a CD-ROM drive add-on for Nintendo's Super Nintendo Entertainment System (a.k.a. Super Famicom in Japan) video game console, in response to Sega's Sega CD. When the prospect of releasing the system as an add-on dissolved, Sony redesigned the machine into a stand alone unit. The PlayStation was released in Japan on December 3, 1994 and later in North America on September 9, 1995. Currently the highest selling home console of all time, SCE's second home console, the PlayStation 2 (PS2 or PSX2) was released in Japan on March 4, 2000, and later in North America and Europe in October and November 2000, respectively. The PS2 is powered by a proprietary central processing unit, the Emotion Engine, and was the first video game console to have DVD playback functionality included out of the box. Initially, the system was criticized for its complex development environment, due mainly to the proprietary hardware included, however despite these complaints the PlayStation 2 received widespread support from third party developers throughout its lifespan on the market. Today it has sold up to 150 million units world wide. The PlayStation Portable (PSP) is SCE's first foray into the small handheld console market, which was and to this date still is dominated by Nintendo. Its development was first announced during SCE's E3 conference in 2003, and it was officially unveiled during their E3 conference on May 11, 2004. The system was released in Japan on December 12, 2004, in North America on March 24, 2005 and in Europe and Australia on September 1, 2005. The console has since seen two major redesigns, with new features including a smaller size, more internal memory, a better quality LCD screen and a lighter weight. A new design, the PSP Go, was released on October 1, 2009 for North America and Europe and on November 1, 2009 for Japan. It has a 3.8" LCD which slides up to reveal the main controls. The PSP Go is 45% lighter and 56% smaller than the original PSP and does not support UMD. The device does support Bluetooth and will be completely digital meaning all media must be downloaded or transferred to the device which has 16 GB of internal flash memory.

The newest home console in the PlayStation family, as well as Sony's entry in the seventh-generation of consoles, the PlayStation 3 (PS3) was launched in November 2006. It utilizes a unique processing architecture, the Cell microprocessor, a proprietary technology developed by Sony in conjunction with Toshiba and IBM. The graphics processing unit, the RSX 'Reality Synthesizer', was co-developed by Nvidia and Sony. Several variations of the PS3 have been released, each with slight hardware and software differences, each denoted by the varying size of the included hard disk drive.

The newest handheld console in the PlayStation family is the PlayStation Vita. It is the successor to the PlayStation Portable as part of the PlayStation brand of gaming devices. It was released in Japan and parts of Asia on December 17, 2011^[22] and in Europe, Australia and North America on February 22, 2012.^[23][24] Internally, the Vita features a 4 core ARM Cortex-A9 MPCore processor and a 4 core SGX543MP4+ graphics processing unit, as well as LiveArea software as its main user interface, which succeeds the XrossMediaBar.^[25][26]

In June 2011, it was announced that Kaz Hirai was to become Chairman of Sony Computer Entertainment and Andrew House to become President and Group CEO as of September 1, 2011.^[31]

Headquarters[link]

SCE currently has three main headquarters around the world: Minami-Aoyama, Minato, Tokyo, Japan (Sony Computer Entertainment Japan & Sony Computer Entertainment Asia) which control operations in Asia; Foster City, California, USA (Sony Computer Entertainment America) which controls operations in North America; and London, United Kingdom (Sony Computer Entertainment Europe) which controls operations in Europe and Oceania. SCE also has smaller offices and distribution centres in Hollywood, Los Angeles, California, USA; Toronto, Ontario, Canada; Melbourne, Australia; and Seocho-gu, Seoul, South Korea.
