Usability For Graphical User Interfaces


17 Displaying A Report Of All Device

A browser window allows the user to view and navigate through a collection of items, such as files or web pages. Graphical user interfaces use visual conventions to represent the generic information shown. Some conventions are used to build the structure of the static elements on which the user can interact, and define the appearance of the interface. This article explains the most common elements of visual language interfaces found in the WIMP («window, icon, menu, pointer») paradigm, although many are also used at other graphical post-WIMP interfaces. These elements are usually embodied in an interface using a widget toolkit or desktop environment. Some environments use the methods of 3D graphics to project virtual three-dimensional user interface objects onto the screen. As the processing power of computer graphics hardware increases, this becomes less of an obstacle to a smooth user experience.

A GUI uses a combination of technologies and devices to provide a platform that users can interact with, for the tasks of gathering and producing information. Designing the visual composition and temporal behavior of a GUI is an important part of software application programming in the area of human–computer interaction. Its goal is to enhance the efficiency and ease of use for the underlying logical design of a stored program, a design discipline named usability. Methods of user-centered design are used to ensure that the visual language introduced in the design is well-tailored to the tasks. The TouchGFX designer also comes with a large list of application templates that you can use on a choice of STM32 evaluation hardware tools.

The minimize button is immediately to the right of the title bar. Using the pointer, you can move a window to a new location on the screen. To do so, grab the window’s title bar with the pointer, drag the window to a new location, and then release the mouse button to release the window. «Grab» means to position the pointer on a window frame and press and hold the mouse’s select button. If you are satisfied with the font you have selected, choose OK. The font does not change until you exit DECevent and restart the DECevent application.

What is the main advantage of GUI class 10?

There are many benefits to using a GUI. Apart from the fact that it provides users with an intuitive and easy-to-use interface and immediate visual feedback, a GUI also allows a user to open up multiple programs or instances and displays these simultaneously.

WIMPs extensively use modes, as the meaning of all keys and clicks on specific positions on the screen are redefined all the time. Command-line interfaces use modes only in limited forms, such as for current directory and environment variables. GUIs can be made quite hard when dialogs are buried deep in a system or moved about to different places during redesigns. Also, icons and dialog boxes are usually harder for users to script. The Apple Lisa was released in 1983, and various windowing systems existed for DOS operating systems (including PC GEM and PC/GEOS). Individual applications for many platforms presented their own GUI variants. Despite the GUIs advantages, many reviewers questioned the value of the entire concept, citing hardware limits, and problems in finding compatible software.

  • For example a check-box, as seen in Figure 2, provides a way of turning some attribute on or off.
  • When choosing the set of graphical controls, be careful of control mechanisms that work on the desktop but may not transfer to your embedded system.
  • Usually a standard set of controls is available which could be reused many times.
  • Once a user learned a particular control, he would recognize it and immediately know how to manipulate it.

You can now deliver a superior user experience while taking the full advantage of STM32 microcontrollers in terms of real time determinism, lower software complexity, faster boot time and longer battery life. A push button is a control that causes an immediate action, such as telling the DECevent software to print a report by selecting the OK button, as shown in Figure A-7. To press a push button, point to it, and then click the select button on the mouse. There are two ways to choose a function from a pull-down menu using the mouse. To restore a window from an icon, point to the icon and double-click the select button on the mouse. To minimize a window and thus change the window to an icon, position the pointer on the minimize button, as shown in Figure A-2, and click the mouse’s select button.

7 Changing User

A series of elements conforming a visual language have evolved to represent information stored in computers. This makes it easier for people with few computer skills to work with and use computer software. The most common combination of such elements in GUIs is the windows, icons, menus, pointer paradigm, especially in personal computers.
