How Does A Graphical User Interface Work?

They are all human factors type complaints, such as how to copy a file and how to get rid of annoying icons . Finally, people have so many complaints about the X-Windowing System, the third major GUI standard, that there is whole book about what is wrong with it .

When driving, a driver should not have to concentrate on the steering wheel. In the same way, the GUI binds the user of the computer system to the operation and potential software transportes of the computer system . A good GUI design removes the impediment of communication with the computer system and allows the user to work directly on the problem at hand .

Areas for research and likely directions of future GUI design conclude the paper. For example, the early Macintosh Apple used the Trash Can icon as a metaphor for deleting files. However, one can pull items out of a trash can until the trash person comes. As another example, the Windows’95 GUI is the most modern of all GUI. One would expect it to be fairly well developed and relatively error free. However, of the approximately 90 complaints with the Windows’95, none are performance complaints.

This paper will survey the common definitions of what a GUI is and review the three common, GUI standards in the market today. It will then review three of the many human factor concepts underlying good GUI design, which are visual acuity, limits to absolute memory, and the principle of grouping. The paper will then present the effect of these factors on three GUI design areas, the amount of presented information, the grouping of information, and the placement of this information on the screen. Following this section, the ramifications of bad versus good GUI design will be addressed.

1 Graphical User Interfaces¶

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. At a conceptual level, a computer human interface is a «means by which people and computers communicate with each other» . One can make an analogy between a computer system’s GUI and a car’s steering wheel. The wheel directly binds the driver to the operation and functionality of the vehicle.

  • Because its interface will appear to freeze up until the click handler finishes retrieving the web page and returns to the event loop.
  • But if the click handler is written so that it actually retrieves the web page itself, then the web browser will be very painful to use.
  • Each GUI element is defined as a class widget from which you can create object instances for your application.
  • But graphical user interfaces are event-driven programs, which means everything is triggered by an input event handler.
  • You can code or modify prepackaged methods that an object will use to respond to user stimuli.

The idea is that by the time you have learned the basics of Microsoft Word, it will be much easier for you to learn Microsoft PowerPoint since some of the functionality is the same. Usability testing – This consists of having selected users try out the prototype. Designing a good user interface is critical to the success of a system. A good user interface encourages an easy and natural interaction between a user and a system. Ideally, a user can forget that she is using a computer and get on with what she wants to do.

What GUI stands for?

A graphical user interface (GUI) is a type of user interface through which users interact with electronic devices via visual indicator representations.

If the functionality that the user needs is not present, then the user must know the commands that are necessary to proceed with the flow or else they are just stuck with it at the exact point. They also give customers an impression of a shoddy, unprofessional product, especially when a GUI has many of them. Fortunately, they are fairly easy for usability experts to spot. Finally, they are usually easy to correct unless they are due to limitations of the GUI tools used to build the software. This chapter describes the most common GUI control bloopers, with design rules for avoiding them. In recent years, model-based methods, which target specific GUI interactions, have been developed.

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 major GUI paradigms, the Apple Macintosh, the IBM Systems Application Architecture , or the X-Windowing System.

Various types of pointing devices can be used, such as a mouse, a stylus pen, or a human finger on a touch screen. If you have been using different types of software, you may have noticed that many aspects of the interface are very similar across different applications. This is particularly true of applications from the same company.
