The history of the graphical user interface, understood as the use of graphic icons and a pointing device to control a computer, covers a five-decade span of incremental refinements, built on some constant core principles. Several vendors have created their own windowing systems based on independent code, but with basic elements in common that define the WIMP "window, icon, menu and pointing device" paradigm.
There have been important technological achievements, and enhancements to the general interaction in small steps over previous systems. There have been a few significant breakthroughs in terms of use, but the same organizational metaphors and interaction idioms are still in use. Desktop computers are often controlled by computer mice and/or keyboards while laptops often have a pointing stick or touchpad, and smartphones and tablet computers have a touchscreen. The influence of game computers and joystick operation has been omitted.
Early dynamic information devices such as radar displays, where input devices were used for direct control of computer-created data, set the basis for later improvements of graphical interfaces.[2] Some early cathode-ray-tube (CRT) screens used a light pen, rather than a mouse, as the pointing device.
Much of the early research was based on how young children learn. So, the design was based on the childlike characteristics of hand–eye coordination, rather than use of command languages, user-defined macro procedures, or automated transformation of data as later used by adult professionals.
The Xerox Alto (1973) had an early graphical user interface.
Engelbart's work directly led to the advances at Xerox PARC. Several people went from SRI to Xerox PARC in the early 1970s. In 1973, Xerox PARC developed the Alto personal computer. It had a bitmapped screen, and was the first computer to demonstrate the desktop metaphor and graphical user interface (GUI). It was not a commercial product, but several thousand units were built and were heavily used at PARC, as well as other XEROX offices, and at several universities for many years. The Alto greatly influenced the design of personal computers during the late 1970s and early 1980s, notably the Three Rivers PERQ, the Apple Lisa and Macintosh, and the first Sun workstations.
The modern WIMP GUI was first developed at Xerox PARC by Alan Kay, Larry Tesler, Dan Ingalls, David Smith, Clarence Ellis and a number of other researchers. This was introduced in the Smalltalk programming environment. It used windows, icons, and menus (including the first fixed drop-down menu) to support commands such as opening files, deleting files, moving files, etc. In 1974, work began at PARC on Gypsy, the first bitmap What-You-See-Is-What-You-Get (WYSIWYG) cut and paste editor. In 1975, Xerox engineers demonstrated a Graphical User Interface "including icons and the first use of pop-up menus".[5]
In 1981 Xerox introduced a pioneering product, Star, a workstation incorporating many of PARC's innovations. Although not commercially successful, Star greatly influenced future developments, for example at Apple, Microsoft and Sun Microsystems.[6]
Quantel Paintbox
Quantel Paintbox (1981)
Released by digital imaging company Quantel in 1981, the Paintbox was a color graphical workstation with supporting of mouse input, but more oriented for graphics tablets; this model also was notable as one of the first systems with implementation of pop-up menus.[7]
Blit
The Blit, a graphics terminal, was developed at Bell Labs in 1982.
Lisp machines, Symbolics
Lisp machines originally developed at MIT and later commercialized by Symbolics and other manufacturers, were early high-end single user computer workstations with advanced graphical user interfaces, windowing, and mouse as an input device. First workstations from Symbolics came to market in 1981, with more advanced designs in the subsequent years.
Apple Lisa and Macintosh (and later, the Apple IIGS)
Beginning in 1979, started by Steve Jobs and led by Jef Raskin, the Apple Lisa and Macintosh teams at Apple Computer (which included former members of the Xerox PARC group) continued to develop such ideas. The Lisa, released in 1983, featured a high-resolution stationery-based (document-centric) graphical interface atop an advanced hard disk based OS that featured such things as preemptive multitasking and graphically orientedinter-process communication. The comparatively simplified Macintosh, released in 1984 and designed to be lower in cost, was the first commercially successful product to use a multi-panel window interface. A desktop metaphor was used, in which files looked like pieces of paper, file directories looked like file folders, there were a set of desk accessories like a calculator, notepad, and alarm clock that the user could place around the screen as desired, and the user could delete files and folders by dragging them to a trash-can icon on the screen. The Macintosh, in contrast to the Lisa, used a program-centric rather than document-centric design. Apple revisited the document-centric design, in a limited manner, much later with OpenDoc.
There is still some controversy over the amount of influence that Xerox's PARC work, as opposed to previous academic research, had on the GUIs of the Apple Lisa and Macintosh, but it is clear that the influence was extensive, because first versions of Lisa GUIs even lacked icons.[8][9] These prototype GUIs are at least mouse-driven, but completely ignored the WIMP ( "window, icon, menu, pointing device") concept. Screenshots of first GUIs of Apple Lisa prototypes show the early designs. Apple engineers visited the PARC facilities (Apple secured the rights for the visit by compensating Xerox with a pre-IPO purchase of Apple stock) and a number of PARC employees subsequently moved to Apple to work on the Lisa and Macintosh GUI. However, the Apple work extended PARC's considerably, adding manipulatable icons, and drag and drop manipulation of objects in the file system (see Macintosh Finder) for example. A list of the improvements made by Apple, beyond the PARC interface, can be read at Folklore.org.[10] Jef Raskin warns that many of the reported facts in the history of the PARC and Macintosh development are inaccurate, distorted or even fabricated, due to the lack of usage by historians of direct primary sources.[11]
In 1984, Apple released a television commercial which introduced the Apple Macintosh during the telecast of Super Bowl XVIII by CBS,[12] with allusions to George Orwell's noted novel, Nineteen Eighty-Four. The commercial was aimed at making people think about computers, identifying the user-friendly interface as a personal computer which departed from previous business-oriented systems,[13] and becoming a signature representation of Apple products.[14]
In 1986, the Apple IIGS was launched. The IIGS was a very advanced model of the successful Apple II series, based on 16-bit technology (in fact, virtually two machines into one). It came with a new operating system, the Apple GS/OS, which features a Finder-like GUI, very similar to that of the Macintosh series, able to deal with the advanced graphic abilities of its Video Graphics Chip (VGC).
Agat
The Soviet Union Agat PC featured a graphical interface and a mouse device and was released in 1983.[15]
SGI 1000 series and MEX
Founded 1982, SGI introduced the IRIS 1000 Series[16] in 1983.[17] The first graphical terminals (IRIS 1000) shipped in late 1983, and the corresponding workstation model (IRIS 1400) was released in mid-1984. The machines used an early version of the MEX windowing system on top of the GL2 Release 1 operating environment.[18] Examples of the MEX user interface can be seen in a 1988 article in the journal "Computer Graphics",[19] while earlier screenshots can not be found. The first commercial GUI-based systems, these did not find widespread use as to their (discounted) academic list price of $22,500 and $35,700 for the IRIS 1000 and IRIS 1400, respectively.[17] However, these systems were commercially successful enough to start SGI's business as one of the main graphical workstation vendors. In later revisions of graphical workstations, SGI switched to the X window system, which had been developed starting at MIT since 1984 and which became the standard for UNIX workstations.
Visi On
VisiCorp's Visi On was a GUI designed to run on DOS for IBM PCs. It was released in December 1983. Visi On had many features of a modern GUI, and included a few that did not become common until many years later. It was fully mouse-driven, used a bit-mapped display for both text and graphics, included on-line help, and allowed the user to open a number of programs at once, each in its own window, and switch between them to multitask.[20] Visi On did not, however, include a graphical file manager. Visi On also demanded a hard drive in order to implement its virtual memory system used for "fast switching", at a time when hard drives were very expensive.
Digital Research (DRI) created GEM as an add-on program for personal computers. GEM was developed to work with existing CP/M and MS-DOS compatible operating systems on business computers such as IBM PC compatibles. It was developed from DRI software, known as GSX, designed by a former PARC employee. Its similarity to the Macintosh desktop led to a copyright lawsuit from Apple Computer, and a settlement which involved some changes to GEM. This was to be the first of a series of "look and feel" lawsuits related to GUI design in the 1980s.
GEM received widespread use in the consumer market from 1985, when it was made the default user interface built into the Atari TOS operating system of the Atari ST line of personal computers. It was also bundled by other computer manufacturers and distributors, such as Amstrad. Later, it was distributed with the best-sold Digital Research version of DOS for IBM PC compatibles, the DR-DOS 6.0. The GEM desktop faded from the market with the withdrawal of the Atari ST line in 1992 and with the popularity of the MicrosoftWindows 3.0 in the PC front around the same period of time. The Falcon030, released in 1993 was the last computer from Atari to use GEM.
Tandy's DeskMate appeared in the early 1980s on its TRS-80 machines and was ported to its Tandy 1000 range in 1984. Like most PC GUIs of the time, it depended on a disk operating system such as TRSDOS or MS-DOS. The application was popular at the time and included a number of programs like Draw, Text and Calendar, as well as attracting outside investment such as Lotus 1-2-3 for DeskMate.
MSX-View was developed for MSX computers by ASCII Corporation and HAL Laboratory. MSX-View contains software such as Page Edit, Page View, Page Link, VShell, VTed, VPaint and VDraw. An external version of the built-in MSX View of the Panasonic FS-A1GT was released as an add-on for the Panasonic FS-A1ST on disk instead of 512KB ROM DISK.
Amiga Intuition and the Workbench
The Amiga computer was launched by Commodore in 1985 with a GUI called Workbench. Workbench was based on an internal engine developed mostly by RJ Mical, called Intuition, which drove all the input events. The first versions used a blue/orange/white/black default palette, which was selected for high contrast on televisions and composite monitors. Workbench presented directories as drawers to fit in with the "workbench" theme. Intuition was the widget and graphics library that made the GUI work. It was driven by user events through the mouse, keyboard, and other input devices.
Due to a mistake made by the Commodore sales department, the first floppies of AmigaOS (released with the Amiga1000) named the whole OS "Workbench". Since then, users and CBM itself referred to "Workbench" as the nickname for the whole AmigaOS (including Amiga DOS, Extras, etc.). This common consent ended with release of version 2.0 of AmigaOS, which re-introduced proper names to the installation floppies of AmigaDOS, Workbench, Extras, etc.
Starting with Workbench 1.0, AmigaOS treated the Workbench as a backdrop, borderless window sitting atop a blank screen. With the introduction of AmigaOS 2.0, however, the user was free to select whether the main Workbench window appeared as a normally layered window, complete with a border and scrollbars, through a menu item.
Amiga users were able to boot their computer into a command-line interface (also known as the CLI or Amiga Shell). This was a keyboard-based environment without the Workbench GUI. Later they could invoke it with the CLI/SHELL command "LoadWB" which loaded Workbench GUI.
One major difference between other OS's of the time (and for some time after) was the Amiga's fully multi-tasking operating system, a powerful built-in animation system using a hardware blitter and copper and four channels of 26kHz 8-bit sampled sound. This made the Amiga the first multi-media computer years before other OS's.
Like most GUIs of the day, Amiga's Intuition followed Xerox's, and sometimes Apple's, lead. But a CLI was included which dramatically extended the functionality of the platform. However, the CLI/Shell of Amiga is not just a simple text-based interface like in MS-DOS, but another graphic process driven by Intuition, and with the same gadgets included in Amiga's graphics.library. The CLI/Shell interface integrates itself with the Workbench, sharing privileges with the GUI.
The Amiga Workbench evolved over the 1990s, even after Commodore's 1994 bankruptcy.
Acorn's 8-bit BBC Master Compact shipped with Acorn's first public GUI interface in 1986.[21] Little commercial software, beyond that included on the Welcome disk, was ever made available for the system, despite the claim by Acorn at the time that "the major software houses have worked with Acorn to make over 100 titles available on compilation discs at launch".[22] The most avid supporter of the Master Compact appeared to be Superior Software, who produced and specifically labelled their games as 'Master Compact' compatible.
Originally branded as the Arthur 1.20 the subsequent Arthur 2 release was shipped under the name RISC OS 2.
Desktop
The WIMP interface incorporates three mouse buttons (named Select, Menu and Adjust), context-sensitive menus, window stack control (i.e. send to back) and dynamic window focus (a window can have input focus at any position on the stack). The Icon bar (Dock) holds icons which represent mounted disc drives, RAM discs, network directories, running applications, system utilities and docked: Files, Directories or inactive Applications. These icons and open windows have context-sensitive menus and support drag-and-drop behaviour. They represent the running application as a whole, irrespective of whether it has open windows.
The application has control of the context-sensitive menus, inapplicable menu choices can be 'greyed out' to make them unavailable. Menus have their own titles and may be moved around the desktop by the user. Any menu can have further sub-menus or a new window for complicated choices.
The GUI is centered around the concept of files. The Filer displays the contents of a disc. Applications are run from the Filer view and files can be dragged to the Filer view from applications to perform saves. The opposite can perform a load. With their co-operation data can be copied or moved directly between applications by saving (dragging) to another application.
Application directories are used to store applications. The OS differentiates them from normal directories through the use of a pling (exclamation mark, also called shriek) prefix. Double-clicking on such a directory launches the application rather than opening the directory. The application's executable files and resources are contained within the directory, but normally they remain hidden from the user. Because applications are self-contained, this allows drag-and-drop installation and removal.
Files are normally typed. RISC OS has some predefined types. Applications can supplement the set of known types. Double-clicking a file with a known type will launch the appropriate application to load the file.
The RISC OSStyle Guide encourages a consistent look and feel across applications. This was introduced in RISC OS 3 and specifies application appearance and behaviour. Acorn's own main bundled applications were not updated to comply with the guide until RISCOS Ltd's Select release in 2001.[24]
Font manager
The outline fonts manager provides spatial anti-aliasing of fonts, the OS being the first operating system to include such a feature,[25][26][27][28] having included it since before January 1989.[29] Since 1994, in RISC OS 3.5, it has been possible to use an outline anti-aliased font in the WindowManager for UI elements, rather than the bitmap system font from previous versions.[30]
MS-DOS file managers and utility suites
Because most of the very early IBM PC and compatibles lacked any common true graphical capability (they used the 80-column basic text mode compatible with the original MDA display adapter), a series of file managers arose, including Microsoft's DOS Shell, which features typical GUI elements as menus, push buttons, lists with scrollbars and mouse pointer. The name text-based user interface was later invented to name this kind of interface. Many MS-DOS text mode applications, like the default text editor for MS-DOS 5.0 (and related tools, like QBasic), also used the same philosophy. The IBM DOS Shell included with IBM DOS 5.0 (circa 1992) supported both text display modes and actual graphics display modes, making it both a TUI and a GUI, depending on the chosen mode.
Advanced file managers for MS-DOS were able to redefine character shapes with EGA and better display adapters, giving some basic low resolution icons and graphical interface elements, including an arrow (instead of a coloured cell block) for the mouse pointer. When the display adapter lacks the ability to change the character's shapes, they default to the CP437 character set found in the adapter's ROM. Some popular utility suites for MS-DOS, as Norton Utilities (pictured) and PC Tools used these techniques as well.
DESQview was a text mode multitasking program introduced in July 1985. Running on top of MS-DOS, it allowed users to run multiple DOS programs concurrently in windows. It was the first program to bring multitasking and windowing capabilities to a DOS environment in which existing DOS programs could be used. DESQview was not a true GUI but offered certain components of one, such as resizable, overlapping windows and mouse pointing.
Applications under MS-DOS with proprietary GUIs
Before the MS-Windows age, and with the lack of a true common GUI under MS-DOS, most graphical applications which worked with EGA, VGA and better graphic cards had proprietary built-in GUIs. One of the best known such graphical applications was Deluxe Paint, a popular painting software with a typical WIMP interface.
The original Adobe Acrobat Reader executable file for MS-DOS was able to run on both the standard Windows 3.x GUI and the standard DOS command prompt. When it was launched from the command prompt, on a machine with a VGA graphics card, it provided its own GUI.
The main window of a given application can occupy the full screen in maximized status. The users must then to switch between maximized applications using the Alt+Tab keyboard shortcut; no alternative with the mouse except for de-maximize. When none of the running application windows are maximized, switching can be done by clicking on a partially visible window, as is the common way in other GUIs.
In 1988, Apple sued Microsoft for copyright infringement of the Lisa and Apple Macintosh GUI. The court case lasted 4 years before almost all of Apple's claims were denied on a contractual technicality. Subsequent appeals by Apple were also denied. Microsoft and Apple apparently entered a final, private settlement of the matter in 1997.
GEOS was launched in 1986, originally written for the 8-bit home computer Commodore 64, and shortly after, the Apple II series. The name was later used by the company as PC/Geos for IBM PC systems, then Geoworks Ensemble. It came with several application programs like a calendar and word processor. A cut-down version served as the basis for America Online's DOS client. Compared to the competing Windows 3.0 GUI, it could run reasonably well on simpler hardware, but its developer had a restrictive policy towards third-party developers that prevented it from becoming a serious competitor. Additionally, it was targeted at 8-bit machines, whilst the 16-bit computer age was dawning.
The standard windowing system in the Unix world is the X Window System (commonly X11 or X), first released in the mid-1980s. The W Window System (1983) was the precursor to X; X was developed at MIT as Project Athena. Its original purpose was to allow users of the newly emerging graphic terminals to access remote graphics workstations without regard to the workstation's operating system or the hardware. Due largely to the availability of the source code used to write X, it has become the standard layer for management of graphical and input/output devices and for the building of both local and remote graphical interfaces on virtually all Unix, Linux and other Unix-like operating systems, with the notable exceptions of macOS and Android.
X allows a graphical terminal user to make use of remote resources on the network as if they were all located locally to the user by running a single module of software called the X server. The software running on the remote machine is called the client application. X's network transparency protocols allow the display and input portions of any application to be separated from the remainder of the application and 'served up' to any of a large number of remote users. X is available today as free software.
The PostScript-based NeWS (Network extensible Window System) was developed by Sun Microsystems in the mid-1980s. For several years SunOS included a window system combining NeWS and the X Window System. Although NeWS was considered technically elegant by some commentators, Sun eventually dropped the product. Unlike X, NeWS was always proprietary software.
The 1990s: Mainstream usage of the desktop
The widespread adoption of the PC platform in homes and small businesses popularized computers among people with no formal training. This created a fast-growing market, opening an opportunity for commercial exploitation and of easy-to-use interfaces and making economically viable the incremental refinement of the existing GUIs for home systems.
After Windows 3.11, Microsoft started development on a new consumer-oriented version of the operating system. Windows 95 was intended to integrate Microsoft's formerly separate MS-DOS and Windows products and included an enhanced version of DOS, often referred to as MS-DOS 7.0. It also featured a significant redesign of the GUI, dubbed "Cairo". While Cairo never really materialized, parts of Cairo found their way into subsequent versions of the operating system starting with Windows 95. Both Win95 and WinNT could run 32-bit applications, and could exploit the abilities of the Intel 80386CPU, as the preemptivemultitasking and up to 4GiB of linear address memory space. Windows 95 was touted as a 32-bit based operating system but it was actually based on a hybrid kernel (VWIN32.VXD) with the 16-bit user interface (USER.EXE) and graphic device interface (GDI.EXE) of Windows for Workgroups (3.11), which had 16-bit kernel components with a 32-bit subsystem (USER32.DLL and GDI32.DLL) that allowed it to run native 16-bit applications as well as 32-bit applications. In the marketplace, Windows 95 was an unqualified success, promoting a general upgrade to 32-bit technology, and within a year or two of its release had become the most successful operating system ever produced.
Accompanied by an extensive marketing campaign,[33] Windows 95 was a major success in the marketplace at launch and shortly became the most popular desktop operating system.[34]
Windows 95 saw the beginning of the browser wars, when the World Wide Web began receiving a great deal of attention in popular culture and mass media. Microsoft at first did not see potential in the Web, and Windows 95 was shipped with Microsoft's own online service called The Microsoft Network, which was dial-up only and was used primarily for its own content, not internet access. As versions of Netscape Navigator and Internet Explorer were released at a rapid pace over the following few years, Microsoft used its desktop dominance to push its browser and shape the ecology of the web mainly as a monoculture.
Windows 95 evolved through the years into Windows 98 and Windows ME. Windows ME was the last in the line of the Windows 3.x-based operating systems from Microsoft. Windows underwent a parallel 32-bit evolutionary path, where Windows NT 3.1 was released in 1993. Windows NT (for New Technology)[35] was a native 32-bit operating system with a new driver model, was unicode-based, and provided for true separation between applications. Windows NT also supported 16-bit applications in an NTVDM, but it did not support VxD based drivers. Windows 95 was supposed to be released before 1993 as the predecessor to Windows NT. The idea was to promote the development of 32-bit applications with backward compatibility – leading the way for more successful NT release. After multiple delays, Windows 95 was released without unicode and used the VxD driver model. Windows NT 3.1 evolved to Windows NT 3.5, 3.51 and then 4.0 when it finally shared a similar interface with its Windows 9x desktop counterpart and included a Start button. The evolution continued with Windows 2000, Windows XP, Windows Vista, then Windows 7. Windows XP and higher were also made available in 64-bit modes. Windows server products branched off with the introduction of Windows Server 2003 (available in 32-bit and 64-bit IA64 or x64), then Windows Server 2008 and then Windows Server 2008 R2. Windows 2000 and XP shared the same basic GUI although XP introduced Visual Styles. With Windows 98, the Active Desktop theme was introduced, allowing an HTML approach for the desktop, but this feature was coldly received by customers, who frequently disabled it. At the end, Windows Vista definitively discontinued it, but put a new SideBar on the desktop.
Mac OS
The Macintosh's GUI has been revised multiple times since 1984, with major updates including System 7 and Mac OS 8. It underwent its largest revision to date with the introduction of the "Aqua" interface in 2001's Mac OS X. It was a new operating system built primarily on technology from NeXTSTEP with UI elements of the original Mac OS grafted on. macOS uses a technology known as Quartz, for graphics rendering and drawing on-screen. Some interface features of macOS are inherited from NeXTSTEP (such as the Dock, the automatic wait cursor, or double-buffered windows giving a solid appearance and flicker-free window redraws), while others are inherited from the old Mac OS operating system (the single system-wide menu-bar). Mac OS X 10.3 introduced features to improve usability including Exposé, which is designed to make finding open windows easier.
With Mac OS X 10.4 released in April 2005,[36][circular reference] new features were added, including Dashboard (a virtual alternate desktop for mini specific-purpose applications) and a search tool called Spotlight, which provides users with an option for searching through files instead of browsing through folders.
With Mac OS X 10.7 released in July 2011, included support for full screen apps and Mac OS X 10.11 (El Capitan) released in September 2015 support creating a full screen split view by pressing the green button on left upper corner of the window or Control+Cmd+F keyboard shortcut.
In the early days of X Window development, Sun Microsystems and AT&T attempted to push for a GUI standard called OPEN LOOK in competition with Motif. OPEN LOOK was developed from scratch in conjunction with Xerox, while Motif was a collective effort.[37] Motif eventually gained prominence and became the basis for Hewlett-Packard's Visual User Environment (VUE), which later became the Common Desktop Environment (CDE).
In the late 1990s, there was significant growth in the Unix world, especially among the free software community. New graphical desktop movements grew up around Linux and similar operating systems, based on the X Window System. A new emphasis on providing an integrated and uniform interface to the user brought about new desktop environments, such as KDE Plasma 5, GNOME and Xfce which have supplanted CDE in popularity on both Unix and Unix-like operating systems. The Xfce, KDE and GNOME look and feel each tend to undergo more rapid change and less codification than the earlier OPEN LOOK and Motif environments.
Amiga
Later releases added improvements over the original Workbench, like support for high-color Workbench screens, context menus, and embossed 2D icons with pseudo-3D aspect. Some Amiga users preferred alternative interfaces to standard Workbench, such as Directory Opus Magellan.
The use of improved, third-party GUI engines became common amongst users who preferred more attractive interfaces – such as Magic User Interface (MUI), and ReAction. These object-oriented graphic engines driven by user interface classes and methods were then standardized into the Amiga environment and changed Amiga Workbench to a complete and modern guided interface, with new standard gadgets, animated buttons, true 24-bit-color icons, increased use of wallpapers for screens and windows, alpha channel, transparencies and shadows as any modern GUI provides.
Use of object oriented graphic engines dramatically changes the look and feel of a GUI to match actual styleguides.
OS/2
Originally collaboratively developed by Microsoft and IBM to replace DOS, OS/2 version 1.0 (released in 1987) had no GUI at all. Version 1.1 (released 1988) included Presentation Manager (PM), an implementation of IBM Common User Access, which looked a lot like the later Windows 3.1 UI. After the split with Microsoft, IBM developed the Workplace Shell (WPS) for version 2.0 (released in 1992), a quite radical, object-oriented approach to GUIs. Microsoft later imitated much of this look in Windows 95[citation needed].
The NeXTSTEP user interface was used in the NeXT line of computers. NeXTSTEP's first major version was released in 1989. It used Display PostScript for its graphical underpinning. The NeXTSTEP interface's most significant feature was the Dock, carried with some modification into Mac OS X, and had other minor interface details that some found made it easier and more intuitive to use than previous GUIs. NeXTSTEP's GUI was the first to feature opaque dragging of windows in its user interface, on a comparatively weak machine by today's standards, ideally aided by high performance graphics hardware.
BeOS
BeOS was developed on custom AT&T Hobbit-based computers before switching to PowerPC hardware by a team led by former Apple executive Jean-Louis Gassée as an alternative to Mac OS. BeOS was later ported to Intel hardware. It used an object-oriented kernel written by Be, and did not use the X Window System, but a different GUI written from scratch. Much effort was spent by the developers to make it an efficient platform for multimedia applications. Be Inc. was acquired by PalmSource, Inc. (Palm Inc. at the time) in 2001. The BeOS GUI still lives in Haiku, an open-source software reimplementation of the BeOS.
Current trends
Mobile devices
General Magic is the apparent parent of all modern smartphone GUI, i.e. touch-screen based including the iPhone et al. In 2007, with the iPhone[38] and later in 2010 with the introduction of the iPad,[39] Apple popularized the post-WIMP style of interaction for multi-touch screens, with those devices considered to be milestones in the development of mobile devices.[40][41]
Other portable devices such as MP3 players and cell phones have been a burgeoning area of deployment for GUIs in recent years. Since the mid-2000s, a vast majority of portable devices have advanced to having high-screen resolutions and sizes. (The Galaxy Note 4's 2,560 × 1,440 pixel display is an example). Because of this, these devices have their own famed user interfaces and operating systems that have large homebrew communities dedicated to creating their own visual elements, such as icons, menus, wallpapers, and more. Post-WIMP interfaces are often used in these mobile devices, where the traditional pointing devices required by the desktop metaphor are not practical.
As high-powered graphics hardware draws considerable power and generates significant heat, many of the 3D effects developed between 2000 and 2010 are not practical on this class of device. This has led to the development of simpler interfaces making a design feature of two dimensionality such as exhibited by the Metro (Modern) UI first used in Windows 8 and the 2012 Gmail redesign.[citation needed][dubious–discuss]
In the first decade of the 21st century, the rapid development of GPUs led to a trend for the inclusion of 3D effects in window management. It is based in experimental research[citation needed] in user interface design trying to expand the expressive power of the existing toolkits in order to enhance the physical cues that allow for direct manipulation. New effects common to several projects are scale resizing and zooming, several windows transformations and animations (wobbly windows, smooth minimization to system tray...), composition of images (used for window drop shadows and transparency) and enhancing the global organization of open windows (zooming to virtual desktops, desktop cube, Exposé, etc.) The proof-of-concept BumpTop desktop combines a physical representation of documents with tools for document classification possible only in the simulated environment, like instant reordering and automated grouping of related documents.
These effects are popularized thanks to the widespread use of 3D video cards (mainly due to gaming) which allow for complex visual processing with low CPU use, using the 3D acceleration in most modern graphics cards to render the application clients in a 3D scene. The application window is drawn off-screen in a pixel buffer, and the graphics card renders it into the 3D scene.[42]
This can have the advantage of moving some of the window rendering to the GPU on the graphics card and thus reducing the load on the main CPU, but the facilities that allow this must be available on the graphics card to be able to take advantage of this.
The notebook interface is widely used in data science and other areas of research. Notebooks allow users to mix text, calculations, and graphs in the same interface which was previously impossible with a command-line interface.
A graphical user interface, or GUI, is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based UIs, which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.
Acorn Archimedes is a family of personal computers designed by Acorn Computers of Cambridge, England. The systems are based on Acorn's own ARM architecture processors and the proprietary operating systems Arthur and RISC OS. The first models were introduced in 1987, and systems in the Archimedes family were sold until the mid-1990s.
In computing, a desktop environment (DE) is an implementation of the desktop metaphor made of a bundle of programs running on top of a computer operating system that share a common graphical user interface (GUI), sometimes described as a graphical shell. The desktop environment was seen mostly on personal computers until the rise of mobile computing. Desktop GUIs help the user to easily access and edit files, while they usually do not provide access to all of the features found in the underlying operating system. Instead, the traditional command-line interface (CLI) is still used when full control over the operating system is required.
In computing, a window is a graphical control element. It consists of a visual area containing some of the graphical user interface of the program it belongs to and is framed by a window decoration. It usually has a rectangular shape that can overlap with the area of other windows. It displays the output of and may allow input to one or more processes.
OPEN LOOK is a graphical user interface (GUI) specification for UNIX workstations. It was originally defined in the late 1980s by Sun Microsystems and AT&T Corporation.
In computing, the desktop metaphor is an interface metaphor which is a set of unifying concepts used by graphical user interfaces to help users interact more easily with the computer. The desktop metaphor treats the computer monitor as if it is the top of the user's desk, upon which objects such as documents and folders of documents can be placed. A document can be opened into a window, which represents a paper copy of the document placed on the desktop. Small applications called desk accessories are also available, such as a desk calculator or notepad, etc.
In computing, an icon is a pictogram or ideogram displayed on a computer screen in order to help the user navigate a computer system. The icon itself is a quickly comprehensible symbol of a software tool, function, or a data file, accessible on the system and is more like a traffic sign than a detailed illustration of the actual entity it represents. It can serve as an electronic hyperlink or file shortcut to access the program or data. The user can activate an icon using a mouse, pointer, finger, or voice commands. Their placement on the screen, also in relation to other icons, may provide further information to the user about their usage. In activating an icon, the user can move directly into and out of the identified function without knowing anything further about the location or requirements of the file or code.
A window manager is system software that controls the placement and appearance of windows within a windowing system in a graphical user interface. Most window managers are designed to help provide a desktop environment. They work in conjunction with the underlying graphical system that provides required functionality—support for graphics hardware, pointing devices, and a keyboard—and are often written and created using a widget toolkit.
In computing, a virtual desktop is a term used with respect to user interfaces, usually within the WIMP paradigm, to describe ways in which the virtual space of a computer's desktop environment is expanded beyond the physical limits of the screen's display area through the use of software. This compensates limits of the desktop area and is helpful in reducing clutter of running graphical applications.
In computing, a shell is a computer program that exposes an operating system's services to a human user or other programs. In general, operating system shells use either a command-line interface (CLI) or graphical user interface (GUI), depending on a computer's role and particular operation. It is named a shell because it is the outermost layer around the operating system.
A menu bar is a graphical control element which contains drop-down menus.
Workbench is the desktop environment and graphical file manager of AmigaOS developed by Commodore International for their Amiga line of computers. Workbench provides the user with a graphical interface to work with file systems and launch applications. It uses a workbench metaphor for representing file system organisation.
Intuition is the native windowing system and user interface (UI) engine of AmigaOS. It was developed almost entirely by RJ Mical. Intuition should not be confused with Workbench, the AmigaOS desktop environment and spatial file manager, which relies on Intuition for handling windows and input events. Workbench uses Intuition to produce displays and AmigaDOS to interact with filing system: AmigaDOS is built on Exec.
A mouse button is an electric switch on a computer mouse which can be pressed (“clicked”) to select or interact with an element of a graphical user interface. Mouse buttons are most commonly implemented as miniature snap-action switches.
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals. After the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians.
AmigaOS is a family of proprietary native operating systems of the Amiga and AmigaOne personal computers. It was developed first by Commodore International and introduced with the launch of the first Amiga, the Amiga 1000, in 1985. Early versions of AmigaOS required the Motorola 68000 series of 16-bit and 32-bit microprocessors. Later versions were developed by Haage & Partner and then Hyperion Entertainment. A PowerPC microprocessor is required for the most recent release, AmigaOS 4.
RISC OS, the computer operating system developed by Acorn Computers for their ARM-based Acorn Archimedes range, was originally released in 1987 as Arthur 0.20, and soon followed by Arthur 0.30, and Arthur 1.20. The next version, Arthur 2, became RISC OS 2 and was completed and made available in April 1989. RISC OS 3 was released with the very earliest version of the A5000 in 1991 and contained a series of new features. By 1996 RISC OS had been shipped on over 500,000 systems.
Mac OS is the series of operating systems developed for the Macintosh family of personal computers by Apple Computer, Inc. from 1984 to 2001, starting with System 1 and ending with Mac OS 9. The Macintosh operating system is credited with having popularized the graphical user interface concept. It was included with every Macintosh that was sold during the era in which it was developed, and many updates to the system software were done in conjunction with the introduction of new Macintosh systems.
Comparison of user features of operating systems refers to a comparison of the general user features of major operating systems in a narrative format. It does not encompass a full exhaustive comparison or description of all technical details of all operating systems. It is a comparison of basic roles and the most prominent features. It also includes the most important features of the operating system's origins, historical development, and role.
