Graphical User Interface


Newer automobiles use GUIs in their navigation systems and multimedia centers, or navigation multimedia center combinations.

Long-running processing should be moved to a background thread, but the Swing view tree is confined to the event-dispatch thread. So accessing Swing objects from another thread requires using the event loop as a message-passing queue, to get back to the event-dispatch thread. Too much work in the event-dispatch thread – the UI is doing a lot of computation in response to your button press, and it hasn’t returned to the event loop to handle more input events yet. Deadlock – two different parts of the UI are trying to acquire locks on the view tree, and are deadlocking with each other.

1 Graphical User Interfaces¶

What are the types of graphical user interface?

Interfaces that are graphical in nature are known either as Graphical User Interfaces (GUI) or WIMP interfaces (Windows, Icons, Menus and Pointer).
These are:Graphical User Interfaces (GUI)
Command Line Interfaces (CLI)
Form-based interfaces.
Menu-based interfaces.
Natural language interfaces.

Tullis’ experiments in the mid-1980s showed that the best predictors of search time were the number of and size of the groups. Therefore, one should structure displays with the limits of visual acuity in mind. The user needs to be able to take in the different chunks of information at one glance to improve readability. Overall, the best predictors of ease of use were density and item alignment.

  • Character user interfaces support automation and scripting and tend to provide greater granular control and a higher level of functionality than graphical user interfaces.
  • The Xerox PARC user interface consisted of graphical elements such as windows, menus, radio buttons, and check boxes.
  • 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 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.

Window managers and other software combine to simulate the desktop environment with varying degrees of realism. By the 1980s, cell phones and handheld game systems also employed application specific touchscreen GUIs.

The top-down approach also allows for the development of emergent features. An emergent feature is a global property of a set that is not evident when one views each item locally. Since global processing tends to be automatic, one can argue that an emerged feature reduces the attention demand as a user operates a multi-element display.

What does GUI mean in text?

Summary of Key Points. «Graphical User Interface» is the most common definition for GUI on Snapchat, WhatsApp, Facebook, Twitter, and Instagram. GUI. Definition: Graphical User Interface.

Unless you’ve been living in the jungle for the last 30 years like our primate friends, you’ve probably heard of Microsoft Windows and Apple Mac OS X, both of which are operating systems that come with their own GUIs. Some other GUIs currently used include Chrome OS, GNOME, and KDE, which are GUIs for Linux , and Android . The main idea is to present self-explanatory (or at least guessable!) picture-like doodads, so that simply moving them around and clicking will result in user joy. Of course, text characters will probably always be involved at some point (for example, doing a web search or writing that blog article would be super hard using just icons!). An icon is the visual representation of an application, folder, file or web browser through a picture. All files that you create in the same application will have the icon of the application, as well as the same extension.

First Attempts To Tackle The Gui Problem

For this performance enhancement, one must use the Gestalt Principle in the initial placement, and the resulting organization must be compatible with the user’s cognitive view of the task . The historical development of the GUI still impacts the three major GUI paradigms in the market today. Historically, all modern GUI are off-shoots of the Apple Macintosh. This has lead to a great deal of standardization and consistency among GUI design criteria. Therefore, most application’s GUI adhere to one of the three software construccion major GUI paradigms, the Apple Macintosh, the IBM Systems Application Architecture , or the X-Windowing System. While none of these GUI designs are perfect, the overall design concepts are good enough to make radical departures counterproductive , unless there are significant performance enhancements. By having a GUI, computers have become more useful to many more people, who don’t have to be computer experts anymore in order to use a computer for common things, such as editing text or viewing photos.

One could learn a programming language like Python, Ruby, Java, Dot Net and many more to develop different types of applications. As said above, there are a lot of standards and GUI delines for a programmer to design and develop a GUI. A good GUI provides a lot of freedom to users like backtracking to the last step. A user with no computer knowledge can literally start learning about the machine because of GUI as it provides scope for users to explore and provides discoverability.

This is particularly inconvenient because you have to literally feed-in commands for each and every action. If there is no GUI, we have to open a command prompt and add the application command line Interface and feed instructions to start an application, run the video player, etc. In the above screen, if you want to access or start an application, say a video player, then all we need is to click the VLC Media player icon using the pointer. Yes, GUI helps the user to understand the functionalities present within the computer through Graphical icons and a click on the icon initiates the action and the desired communication of the user. It was designed and priced for high-end corporate workstations. Most modern operating systems provide both a GUI and some level of a CLI, although the GUIs usually receive more attention. The GUI is usually WIMP-based, although occasionally other metaphors surface, such as those used in Microsoft Bob, 3dwm, or File System Visualizer.
