Usability For Graphical User Interfaces


It is the result of processed user input and usually the main interface for human-machine interaction. The touch user interfaces popular on small mobile devices are an overlay of the visual output to the visual input. This guide is intended to teach you how to use the DECevent graphical user interface. Therefore, this guide provides only a brief overview of the Motif Window Manager; it is not intended to be a comprehensive introduction to windows or to the DECevent application. In many small-screen situations it will not be possible to make all of the menu visible at once. On a desktop interface the user can usually manipulate the scrollbar with a mouse. The scrollbar is acting as an input mechanism as well as an output mechanism.

  • Other options as described in block 315 may alternatively be displayed.
  • After determining the closest airports to the point of interest, the flight search system 140 communicates the list to the user computing device 110 for display in the graphical user interface 114 to the user 101.
  • In the example, the results box 402 displays three airports deemed most convenient or closest to the user 101.
  • The selection of the number of airports to display and which airports to display is performed as described in blocks 310 to 315 herein.
  • The results box 402 indicates the distance from the point of interest to each airport.

On the screen, there is a special icon called a cursor whose position defines the current focus of the user, and all input given by the user will be delivered to the window where the cursor is located. The user can select any object he or she wants freely by moving the cursor to the top of the object and clicking a button on the mouse. A double click usually means to invoke a task represented by the clicked icon. Because users can intuitively manipulate objects, GUI is also referred to as direct manipulation user interface . The benefits of visualizations in computing are evident in the intuitive nature of graphical user interfaces. Visualization and interactivity are similarly beneficial elements in data analytics. Three-dimensional GUIs appeared in science fiction literature and films before they were technically feasible or in common use.

What is GUI and its advantages?

Advantage #1 – GUIs enable interaction through clarity and control. The primary objective of every GUI is to deliver the kind of clarity that will allow its users to rapidly begin engaging and interacting with it in meaningful ways.

The concept of icons was later introduced by David Canfield Smith, who had written a thesis on the subject under the guidance of Kay. The PARC user interface employs a pointing device along with a keyboard. These aspects can be emphasized by using the alternative term and acronym for windows, icons, menus, pointing device . This effort culminated in the 1973 Xerox Alto, the first computer with a GUI, though the system never reached commercial production. The graphical user interface is presented on the computer screen.

Is a type of GUI?

Interfaces that are graphical in nature are known either as Graphical User Interfaces (GUI) or WIMP interfaces (Windows, Icons, Menus and Pointer).

For example; the 1993 American film Jurassic Park features Silicon Graphics’ three-dimensional file manager File System Navigator, a real-life file manager for Unix operating systems. The film Minority Report has scenes of police officers using specialized 3D data systems. In prose fiction, three-dimensional user interfaces have been portrayed as immersible environments like William Gibson’s Cyberspace or Neal Stephenson’s Metaverse. Many futuristic imaginings of user interfaces rely heavily on object-oriented user interface style and especially object-oriented graphical user interface style.

While command-line or text-based applications allow users to run a program non-interactively, GUI wrappers atop them avoid the steep learning curve of the command-line, which requires commands to be typed on the keyboard. By starting a GUI wrapper, users can intuitively interact with, start, stop, and change its working parameters, through graphical icons and visual indicators of a desktop environment, for example. Applications may also provide both interfaces, and when they do the GUI is usually a WIMP wrapper around the command-line version. This is especially common with applications designed for Unix-like operating systems. The latter used to be implemented first because it allowed the developers to focus exclusively on their product’s functionality without bothering about interface details such as designing icons and placing buttons. Designing programs this way also allows users to run the program in a shell script. The Xerox PARC user interface consisted of graphical elements such as windows, menus, radio buttons, and check boxes.

Using The Motif Window Manager

The flight search system 140 searches databases of potential points of interest to predict or identify the point of interest that the user 101 intends. The flight search system 140 presents the identified point of interest on the graphical user interface 114 to the user 101 for verification. If the identified point of interest is not the point of interest that the user 101 intended, then the user 101 may refine the search. In an example, a flight search system obtains airport data and other data from an airline system, a mapping system, airport management systems, the Federal Aviation Administration, or any other suitable source. The addresses, geo-location, or any other suitable identifier of the locations of airports may be stored in a database on the flight search system. The flight search system applies the locations to a mapping system that operates on the flight search system to allow representation on a graphical user interface to a user.

A graphical user interface offers visual representations of the available commands and functions of an operating system or software program. window and all objects associated with a task are confined in its window.

Search engine systems, such as flight search systems, receive queries for flights and other travel data from one city to a destination city. In conventional systems, flights are typically shown as originating or arriving from an airport designated by a user or a major airport related to the arrival or departure city. In conventional systems, the flight search systems request an input from the user to select a particular airport.

However on many restricted embedded devices, the scrollbar is used for output only. Figure 5 shows two scrollbars that can be drawn with a minimum number of pixels. The position of the middle portion of the scrollbar shows the user where he is relative to the top and bottom of the list. The size of the middle section shows the user what percentage of the entire menu is currently visible on the display. 2, in block 220, the flight search system 140 receives an input moving the location of the point of interest on the map display 500 to a new location. When the user 101 enters a text representation of the point of interest, the flight search system 140 may use any typical autofill algorithm to predict the point of interest name that the user 101 is entering.

3 Displaying Rulesets

During the 1960s more advanced displays were developed that offered more advanced interactive capabilities, meaning that the user could provide input to the computer more easily and efficiently. Among the earliest advanced interactive systems were systems developed by Ivan Sutherland, including his Sketchpad drawing system. Among other innovations, Sutherland created a graphical interaction method that allowed computer users to provide input using a light pen . His research laid the groundwork for more advanced systems that emerged during the mid- and late 1960s, including computer-aided design and computer-aided manufacturing systems that used styli to draw forms and choose commands. GUI is the acronym for graphical user interface, which is the interface through which users interact with electronic devices, such as computers, laptops, smartphones and tablets.
