History of the graphical user interface
From Wikipedia, the free encyclopedia
The graphical user interface, or "GUI" (IPA: [ˈɡuːi]), is a computer interface that uses graphic icons and controls in addition to text. The user of the computer utilizes a pointing device, like a mouse, to manipulate these icons and controls. This is considerably different from the command line interface (CLI) in which the user types a series of text commands to the computer.

[edit] Initial Developments
The concept of a windowing system was introduced by the first real-time graphic display systems for computers: the SAGE Project and Ivan Sutherland's Sketchpad.
[edit] Augmentation of Human Intellect (NLS)
Doug Engelbart's Augmentation of Human Intellect project at SRI in the 1960s developed the On-Line System (NLS), which incorporated a mouse-driven cursor and multiple windows. Engelbart had been inspired, in part, by the memex desk based information machine suggested by Vannevar Bush in 1945. Much of the early research was based on how young humans learn.
[edit] Xerox PARC
Engelbart's work directly led to the advances at Xerox PARC. Several people went from SRI to Xerox PARC in the early 1970's. The Xerox PARC team with Merzouga Wilberts, codified the WIMP (windows, icons, menus and pointers) paradigm, first pioneered on the Xerox Alto experimental computer, but which eventually appeared commercially in the Xerox 8010 ('Star') system in 1981.
[edit] Apple Lisa and Macintosh
Beginning in 1979, started by Steve Jobs and led by Jef Raskin, the Lisa and Macintosh teams at Apple Computer (which included former members of the Xerox PARC group) continued to develop such ideas. The Macintosh, released in 1984, was the first commercially successful product to use a GUI. A desktop metaphor was used, in which files looked like pieces of paper; 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 on the screen. Drop down menus were also introduced.
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 Apple's Lisa and Macintosh, but it is clear that the influence was extensive, because first versions of Lisa GUIs even lacked icons. These prototype GUIs are at least mouse driven, but completely ignored the WIMP concept. Rare screenshots of first GUIs of Apple Lisa prototypes are shown here. Note also that Apple was invited by PARC to view their research, 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 a fixed menu bar and direct manipulation of objects in the file system (see Macintosh Finder) for example. A list of the improvements made by Apple to the PARC interface can be read here (folklore.org)
The Macintosh's GUI has been frequently revised with time since 1984, with major updates including System 7, and underwent its largest revision 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. Mac OS X uses a technology called Quartz for graphics rendering and drawing on-screen. Some interface features of Mac OS X 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 v10.3 introduced features to improve usability including Exposé which is designed to make finding open windows easier.
With Mac OS X v10.4, new features 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 were added.
[edit] DESQview
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.
[edit] GEM
Main article: Atari TOS
Atari Working directly with DRI, a team called the Monterey Group began development of a 68000 based version of GEM for the Atari ST series computer systems. The Project was codenamed "JASON" and developed into TOS (The Operating System). Early myths and rumor mills speculated that TOS really stood for Tramiel Operating System.
TOS 1.0 was initially released commercially with Atari's first ST computer - the Atari 520ST in September of 1985 and was contained on a diskette. Shortly there after TOS was installed into the built in ROM's within the computer system, requiring no Boot disk to load the OS.
TOS would evolve over the next 7 years (1985-1992) with major releases such as Rainbow TOS to exploit new hardware platforms developed by Atari such as the Mega ST line, the later STe and Mega STe which had high resolution color graphics and stereo sound output.
TOS 3.0 would be installed into Atari's TT030 32bit workstation series. The TT030 also would run Atari Unix System V if installed and using a simple BIOS update disk, the system could be set to boot from an Atari AHDI formatted HD or a Atari Unix hard drive.
Atari introduced with its final computer system - the Falcon030 a version of TOS called MultiTOS allowing for Atari's version of the GEM environment to mix with the MiNT OS and share its multitasking features. MultiTOS boasted a much more user friendly desktop environment both visually and functionally.
Though unreleased - copies have circulated around for many years is the Atari TOS 4.92 also referred to as TOS 5 that included several additional enhancements of the Falcon released MultiTOS.
Though with the demise of the Atari ST line of systems in 1992, Ataris version of GEM - TOS still continues to receive numerous minor upgrades, alternative desktops and other enhanced features by individuals, homebrewers and in demo-scene projects.
[edit] Amiga Intuition
The Amiga computer was launched by Commodore in 1985 with a GUI called Workbench based on an internal engine which drives all the input events called Intuition, and developed almost entirely by RJ Mical. The first versions used a garish 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 which were released with 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.).
Early versions of AmigaOS did treat the Workbench as just another window on top of a blank screen, but this is due to the ability of AmigaOS to have invisible screens with a chromakey or a genlock - one of the most advanced features of Amiga platform - even without losing the visibility of Workbench itself. In later AmigaOS versions Workbench could be set as a borderless desktop.
Amiga users were able to boot their computer into a CLI (aka. shell). This was a keyboard-based environment without the Workbench GUI. Later they could invoke it with the CLI/SHELL command LoadWB which performs the task to load Workbench GUI.
Like most GUIs of the day Amiga's Intuition followed Xerox, and sometimes Apple's lead, but a CLI was included which dramatically extended the functionality of the platform. Later releases added more improvements, like support for high-color Workbench screens and 3D icons. Often Amiga users preferred alternative interfaces to standard Workbench, such as Directory Opus, or ScalOS interface. An interesting article about these replacements is available here (in French language).
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 "classes" of graphic objects and functions 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 24bit-color icons, increased use of wallpapers for screens and windows, alpha channel, transparencies and shadows as any modern GUI requires.
Modern derivatives of Workbench are Ambient for MorphOS, ScalOS, Workbench for AmigaOS 4.0 and Wanderer for AROS. There is a brief article on ambient and descriptions of MUI icons, menus and gadget here (aps.fr) and images of Zune stay at main AROS site.
[edit] Microsoft Windows
- See also: History of Microsoft Windows
Microsoft modeled the first version of Windows, released in 1985, on the GUI of the Mac OS. Windows 1.0 was a GUI (graphic user interface) for the MS-DOS operating system that had been the OS of choice for IBM PC and compatible computers since 1981. Windows 2.0 followed, but it wasn't until the 1990 launch of Windows 3.0, based on Common User Access that its popularity truly exploded. The GUI has seen major and minor redesigns since, notably the addition of spatial file management capabilities akin to the Macintosh Finder in Windows 95, known as the Windows Explorer; the contentious web browser integration in Windows 98; the subsequent transition away from spatial file management more towards a single-window, task-based interface with Windows XP; and the removal of the browser integration in Windows Vista.
Windows traditionally differed from other GUIs in that it encouraged using applications maximized, as evident even in this early Windows 1.01 screenshot. The users usually switch between maximized applications using Alt+Tab keyboard shortcut or by clicking on a Taskbar listing all open applications, as opposed to clicking on a partially visible window, as is more common in some 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, and Microsoft and Apple apparently entered a final, private settlement of the matter in 1997 as a side note in a broader announcement of investment and cooperation.
Windows Vista, Microsoft's next-generation operating system released on 30 January 2007 . features the "Aero" interface, with transparency and shading effects as well as a "3D" manipulation of windows. This is the first Windows interface that requires graphics cards with built-in hardware acceleration support. For systems without such cards, the traditional "Basic" and "Classic" interfaces from previous Windows versions are still included.
[edit] GEOS
GEOS was another very early graphical desktop system. Originally written for the 8 bit home computer Commodore 64 it was later ported to IBM PC systems. It came with several application programs like a calendar and word processor, and 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.
Revivals were seen in the HP OmniGo handhelds, Brother GeoBook line of laptop-appliances, and the New Deal Office package for PCs. Related code found its way to earlier 'Zoomer' PDAs, creating an unclear lineage to Palm, Inc.'s later work. Nokia used GEOS as a base operating system for their Nokia Communicator series, before switching to EPOC (Symbian).
[edit] RISC OS
Early versions of what became called RISC OS were known as Arthur, which was released in 1987 by Acorn Computers. RISC OS was a colour GUI operating system which used three-button mice, a taskbar (called the iconbar), and a file navigator similar to that of Mac OS. Acorn created RISC OS in the 1980s for their ARM-CPU based computers. The GUI of RISC OS has developed over versions of RISC OS from 1987 to the present day with version 4.39 having a great ability to customise the interface.
[edit] NeXTSTEP
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.
[edit] 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), which looked a lot like the later Windows 3.0 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 in Windows 95.
[edit] BeOS
BeOS was developed on custom AT&T Hobbit-based computers before switching to PowerPC hardware by a team lead by former Apple executive Jean-Louis Gassée as an alternative to the Macintosh OS and GUI. 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.
[edit] NeWS
The Display PostScript-based NeWS (Network extensible Window System) was developed by Sun Microsystems. 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.
[edit] The X Window System
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.
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.
[edit] GUIs built on X
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 a well-designed standard developed from scratch in conjunction with Xerox, while Motif was a collective effort that fell into place, with a look and feel patterned after Windows 3.11. Many who worked on OPEN LOOK at the time appreciated its design coherence. Motif prevailed in the UNIX GUI battles and became the basis for the Common Desktop Environment (CDE). CDE was based on VUE (Visual User Environment), a proprietary desktop from Hewlett-Packard that in turn was based on the Motif look and feel.
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 and GNOME, which are supplanting CDE in popularity on both Unix and Unix-like operating systems. The KDE and GNOME look and feel each tend to undergo more rapid change and less codification than the earlier OPEN LOOK and Motif environments.
[edit] Trivia
Modern computer games usually develop their own GUIs, which are often (but not always) based on the WIMP paradigm.
