History Of The GUI
The history of the graphical user interface, understood as the use of graphic icon (computing), 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 (computing), 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 interface metaphor, metaphors and interaction Programming idiom, 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 j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivan Sutherland
Ivan Edward Sutherland (born May 16, 1938) is an American computer scientist and Internet pioneer, widely regarded as a pioneer of computer graphics. His early work in computer graphics as well as his teaching with David C. Evans in that subject at the University of Utah in the 1970s was pioneering in the field. Sutherland, Evans, and their students from that era developed several foundations of modern computer graphics. He received the Turing Award from the Association for Computing Machinery in 1988 for the invention of Sketchpad, an early predecessor to the sort of graphical user interface that has become ubiquitous in personal computers. He is a member of the National Academy of Engineering, as well as the National Academy of Sciences among many other major awards. In 2012 he was awarded the Kyoto Prize in Advanced Technology for "pioneering achievements in the development of computer graphics and interactive interfaces". Biography Sutherland's father was from New Zeal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macro (computer Science)
In computer programming, a macro (short for "macro instruction"; ) is a rule or pattern that specifies how a certain input should be mapped to a replacement output. Applying a macro to an input is known as macro expansion. The input and output may be a sequence of lexical tokens or characters, or a syntax tree. Character macros are supported in software applications to make it easy to invoke common command sequences. Token and tree macros are supported in some programming languages to enable code reuse or to extend the language, sometimes for domain-specific languages. Macros are used to make a sequence of computing instructions available to the programmer as a single program statement, making the programming task less tedious and less error-prone. (Thus, they are called "macros" because a "big" block of code can be expanded from a "small" sequence of characters.) Macros often allow positional or keyword parameters that dictate what the conditional assembler program generates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Command Language
A command language is a language for job control (computing), job control in computing. It is a domain-specific language, domain-specific and interpreted language; common examples of a command language are shell script, shell or batch programming languages. These languages can be used directly at the command line, but can also automate tasks that would normally be performed manually at the command line. They share this domain—lightweight automation—with scripting language#Job control languages and shells, scripting languages, though a command language usually has stronger coupling (computer science), coupling to the underlying operating system. Command languages often have either very simple grammars or syntax (programming languages), syntaxes very close to natural language, to shallow the learning curve, as with many other domain-specific languages.

Vannevar Bush
Vannevar Bush ( ; March 11, 1890 – June 28, 1974) was an American engineer, inventor and science administrator, who during World War II headed the U.S. Office of Scientific Research and Development (OSRD), through which almost all wartime military R&D was carried out, including important developments in radar and the initiation and early administration of the Manhattan Project. He emphasized the importance of scientific research to national security and economic well-being, and was chiefly responsible for the movement that led to the creation of the National Science Foundation. Bush joined the Department of Electrical Engineering at Massachusetts Institute of Technology (MIT) in 1919, and founded the company that became the Raytheon Company in 1922. Bush became vice president of MIT and dean of the MIT School of Engineering in 1932, and president of the Carnegie Institution of Washington in 1938. During his career, Bush patented a string of his own inventions. He is known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memex
Memex is a hypothetical electromechanical device for interacting with microform documents and described in Vannevar Bush's 1945 article "As We May Think". Bush envisioned the memex as a device in which individuals would compress and store all of their books, records, and communications, "mechanized so that it may be consulted with exceeding speed and flexibility". The individual was supposed to use the memex as an automatic personal filing system, making the memex "an enlarged intimate supplement to his memory".. The name memex is a portmanteau of ''mem''ory and ''ex''pansion. The concept of the memex influenced the development of early hypertext systems, eventually leading to the creation of the World Wide Web, and personal knowledge base software. The hypothetical implementation depicted by Bush for the purpose of concrete illustration was based upon a document bookmark list of static microfilm pages and lacked a true hypertext system, where parts of pages would have internal ...

Hypertext
Hypertext is E-text, text displayed on a computer display or other electronic devices with references (hyperlinks) to other text that the reader can immediately access. Hypertext documents are interconnected by hyperlinks, which are typically activated by a mouse (computing), mouse click, keypress set, or screen touch. Apart from text, the term "hypertext" is also sometimes used to describe tables, images, and other presentational content formats with integrated hyperlinks. Hypertext is one of the key underlying concepts of the World Wide Web, where Web pages are often written in the Hypertext Markup Language (HTML). As implemented on the Web, hypertext enables the easy-to-use publication of information over the Internet. Etymology The English prefix "hyper-" comes from the Greek language, Greek prefix "ὑπερ-" and means "over" or "beyond"; it has a common origin with the prefix "super-" which comes from Latin. It signifies the overcoming of the previous linear con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NLS (computer System)
NLS, or the "oN-Line System", was a revolutionary computer collaboration system developed in the 1960s. Designed by Douglas Engelbart and implemented by researchers at the Augmentation Research Center (ARC) at the Stanford Research Institute (SRI), the NLS system was the first to employ the practical use of hypertext links, the mouse, raster-scan video monitors, information organized by relevance, screen windowing, presentation programs, and other modern computing concepts. It was funded by ARPA (the predecessor to Defense Advanced Research Projects Agency), NASA, and the US Air Force. Development Douglas Engelbart developed his concepts while supported by the US Air Force from 1959 to 1960 and published a framework in 1962. The strange acronym, NLS (rather than OLS), was an artifact of the evolution of the system. Engelbart's first computers were not able to support more than one user at a time. First was the CDC 160A in 1963, which had very little programming power of its o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menlo Park, California
Menlo Park is a city at the eastern edge of San Mateo County within the San Francisco Bay Area of California in the United States. It is bordered by San Francisco Bay on the north and east; East Palo Alto, Palo Alto, and Stanford to the south; and Atherton, North Fair Oaks, and Redwood City to the west. It is one of the most educated cities in California and the United States; nearly 70% of residents over 25 have earned a bachelor's degree or higher. It had 33,780 residents at the 2020 United States Census. It is home to the corporate headquarters of Meta, and is where Google, Roblox Corporation and Round Table Pizza were founded. Its train station holds the record as the oldest continually operating train station in California. Toponym "Menlo" is derived from Menlo (the anglicized spelling of Irish Gaelic 'Mionloch', meaning 'small lake') in County Galway, Ireland. The name "Menlo Park" was given to a ranch purchased by Irish settlers in honor of their home village in Ire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SRI International
SRI International (SRI) is an American nonprofit scientific research institute and organization headquartered in Menlo Park, California. The trustees of Stanford University established SRI in 1946 as a center of innovation to support economic development in the region. The organization was founded as the Stanford Research Institute. SRI formally separated from Stanford University in 1970 and became known as SRI International in 1977. SRI performs client-sponsored research and development for government agencies, commercial businesses, and private foundations. It also licenses its technologies, forms strategic partnerships, sells products, and creates spin-off companies. SRI's headquarters are located near the Stanford University campus. SRI's annual revenue in 2014 was approximately $540 million, which tripled from 1998 under the leadership of Curtis Carlson. In 1998, the organization was on the verge of bankruptcy when Carlson took over as CEO. Over the next sixteen years wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augmentation Research Center
SRI International's Augmentation Research Center (ARC) was founded in the 1960s by electrical engineer Douglas Engelbart to develop and experiment with new tools and techniques for collaboration and information processing. The main product to come out of ARC was the revolutionary oN-Line System, better known by its abbreviation, NLS. ARC is also known for the invention of the "computer mouse" pointing device, and its role in the early formation of the Internet. Engelbart recruited workers and ran the organization until the late 1970s when the project was commercialized and sold to Tymshare, which was eventually purchased by McDonnell Douglas. Beginnings Some early ideas by Douglas Engelbart were developed in 1959 funded by the Air Force Office of Scientific Research (now Rome Laboratory). By 1962, a framework document was published. J. C. R. Licklider, the first director of the United States Department of Defense's Advanced Research Project Agency (DARPA) Information Processing ...
