![]() And when it’s time, export pages as PDFs, images and CAD files. Learn the basics. LayOut is designed to look, feel, and behave like SketchUp. That means it’s easy to learn too. Watch a master at work. Using LayOut and SketchUp Pro for construction documentation is a powerful process. Learn how one expert creates stunning, effective drawings. Utilities and engineering firms around the world trust WaterCAD as a reliable decision-support tool for their infrastructure. Design new water systems. • • • The history of the, understood as the use of graphic and a pointing device to control a, 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 '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 and interaction are still in use. Although many GUI are controlled by using a mouse, the keyboard can also be used with keyboard shortcuts or arrow keys. The interface developments described, below, have been summarized and omit many details in the interest of brevity. The influence of game computers and operation has been omitted. In my previous tutorial, I wrote about digitally signing emails in Apple Mail to ensure that an email being sent or received is verified as coming from a trusted source. While this does nothing to. (1968) Early dynamic information devices such as displays, where input devices were used for direct control of computer-created data, set the basis for later improvements of graphical interfaces. Some early (CRT) screens used a, rather than a mouse, as the pointing device. The concept of a multi-panel windowing system was introduced by the first real-time graphic display systems for computers: the and 's. Augmentation of Human Intellect (NLS) [ ] In the 1960s, 's project at the at in developed the (NLS). This computer incorporated a mouse-driven cursor and multiple windows used to work on. Engelbart had been inspired, in part, by the desk-based information machine suggested by in 1945. Much of the early research was based on how young children learn. So, the design was based on the childlike primitives of, rather than use of, user-defined procedures, or automated transformations of data as later used by adult professionals. Xerox PARC [ ]. Workstation introduced the first commercial GUI operating system Engelbart's work directly led to the advances at. Several people went from SRI to Xerox PARC in the early 1970s. In 1973, Xerox PARC developed the personal computer. It had a screen, and was the first computer to demonstrate the and (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, the and, and the first workstations. The interim Dynabook environment desktop (1976; aka Smalltalk-76 running on Alto). The GUI was first developed at Xerox PARC by,,,, and a number of other researchers. It used,, and (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 () cut & paste editor. In 1975, Xerox engineers demonstrated a Graphical User Interface 'including icons and the first use of pop-up menus'. In 1981 Xerox introduced a pioneering product,, a incorporating many of PARC's innovations. Although not commercially successful, Star greatly influenced future developments, for example at,. The had an early graphical user interface. The (and later ) was an early personal computer developed at Xerox PARC in 1973. It was the first computer to use the desktop metaphor and mouse-driven graphical user interface (GUI). Mac 11 for sale gun.
