Gui Design


The graphical user interface is presented on the computer screen. It is the result of processed user input and usually the main interface for human-machine interaction.

But the cognitive load still is on the CLI operator – she/he needs to know exactly what to type and may also be more skilled than a GUI operator. A command line interface enables users to type commands in a terminal or console window to interact with an operating system. Users respond to a visual prompt by typing a command on a specified line, and receive a response back from the system. Users type a command or series of commands for each task they want to perform.

Perhaps the most obvious example of CLI’s valueis with those who write code for software programs and web designs. Those who write code know the command codes they need to include and don’t want to waste time pointing and clicking if it’s not necessary. In the industrial design field of human-machine interaction, the user interface is where interaction between humans and machines occurs.

Common devices the public use on a daily basis include smartphones, computers and tablets, which all feature graphical user interfaces. Although it may seem that we have always had the ease of use of GUIs, the public only gained access to this technology in the 1980s. In this article, we provide an overview of what is. Stands for «Graphical User Interface» and is pronounced «gooey.» It is a user interface that includes graphical elements, such as windows, icons and buttons.

The term was created in the 1970s to distinguish graphical interfaces from text-based ones, such as command line interfaces. 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. A web user interface, or web-based graphical user interface, refers to the interaction between a user and software running on a web server wherein the user interface is the web browser and the web page it downloaded and rendered. Technologies such as Flash, Java, JavaScript, and Silverlight enable interactions such as drag-and-drop, playing audio, drawing on the screen, and access to the keyboard and mouse. The advantage of a graphical user interface is a stark improvement in useability for the average person. Graphical user interface applications are self descriptive, feedback is typically immediate, and visual cues encourage and steer discoverability.

Scientifically valid of course, but if you put two application experts side by side, one equiped with the GUI and the other with the CLI – the command line user is much faster than the graphical user interface operator. The reason for this is that CLI don’t «waste» computer power by drawing GUI and CLI don’t provide feedback unless you do things the wrong way.

Does GUI requires more RAM to run?

GUI requires more RAM to run. A character user interface does not need much RAM to run.

The widgets of a well-designed interface are selected to support the actions necessary to achieve the goals of users. A model–view–controller allows flexible structures in which the interface is independent of and indirectly linked to application functions, so the GUI can be customized easily. This allows users to select or design a different skin at will, and eases the designer’s work to change the interface as user needs evolve. Good user interface design relates to users more, and to system architecture less. Large widgets, such as windows, usually provide a frame or container for the main presentation content such as a web page, email message, or drawing.

The visible graphical interface features of an application are sometimes referred to as chrome or GUI . Typically, users interact with information by manipulating visual widgets that allow for interactions appropriate to the kind of data they hold.

  • A GUI provides windows, pull-down menus, buttons, scrollbars, iconic images, wizards, other icons, and the mouse to enable users to interact with the operating system or application.
  • There are a variety of university-level computer-human interaction programs.
  • The graphical user interface (GUI; sometimes pronounced “gooey”) is used by most commercially popular computer operating systems and software programs today.
  • It’s the kind of interface that allows users to manipulate elements on the screen using a mouse, a stylus, or even a finger.
  • Although a few offer breath and diversity, many students graduate from universities that offer only one or two CHI courses.

The touch user interfaces popular on small mobile devices are an overlay of the visual output to the visual input. ) is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based user interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces , which require commands to be typed on a computer keyboard. Older desktop operating systems, such as MS-DOS, as well as many current programming languages, employ command-line interfaces, which require that users type in commands at a command line to access the functions of a system. To do so, a user needs to learn the available commands of a system and has to input these in the correct format for the relevant function to be called. This means that small mistakes, like spelling errors or incorrect spacing, will prevent a function from being executed. Every technological device that requires user interaction employs a user interface.

What does CLI mean?

Command Line Input
CLI is a command line program that accepts text input to execute operating system functions. In the 1960s, using only computer terminals, this was the only way to interact with computers.

Since the commands available in command line interfaces can be many, complex operations can be performed using a short sequence of words and symbols. This allows greater efficiency and productivity once many commands are learned, but reaching this level takes some time because the command words may not be easily discoverable or mnemonic. Also, using the command line can become slow and error-prone when users must enter long commands comprising many parameters or several different filenames at once. However, windows, icons, menus, pointer interfaces present users with many widgets that represent and can trigger some of the system’s available commands.
