Software User Interface Design. User interface is the front end application view to which user interacts in order to use the software. User can manipulate and control the software as well as hardware by means of user interface. Today, user interface is found at almost every place where digital technology exists, right from computers, mobile phones, cars, music players, airplanes, ships etc. User interface is part of software and is designed such a way that it is expected to provide the user insight of the software. UI provides fundamental platform for human computer interaction. UI can be graphical, text based, audio video based, depending upon the underlying hardware and software combination.

An instruction set architecture ISA is the interface between the computers software and hardware and also can be viewed as the programmers view of the machine. Good technical design describes of major hardware components and their functions shows hierarchy organization and functions of the software components. A library of 1200 current and historical NIST cybersecurity publications, including FIPS, SP 800s, NISTIRs, journal articles, conference papers, etc. Software User Interface Design Learn Software Engineering Concepts in simple and easy steps starting from their overview and then covering software analysis. UI can be hardware or software or a combination of both. The software becomes more popular if its user interface is Attractive. Simple to use. Responsive in short time. Clear to understand.

Command Line Interface CLICLI has been a great tool of interaction with computers until the video display monitors came into existence. CLI is first choice of many technical users and programmers. Computer Organization Design Hardware Software Interface Pdf To WordCLI is minimum interface a software can provide to its users. CLI provides a command prompt, the place where the user types the command and feeds to the system. The user needs to remember the syntax of command and its use. Him Ville Valo For. Earlier CLI were not programmed to handle the user errors effectively. A command is a text based reference to set of instructions, which are expected to be executed by the system. There are methods like macros, scripts that make it easy for the user to operate. CLI uses less amount of computer resource as compared to GUI. CLI Elements. A text based command line interface can have the following elements Command Prompt It is text based notifier that is mostly shows the context in which the user is working. It is generated by the software system. Cursor It is a small horizontal line or a vertical bar of the height of line, to represent position of character while typing. Cursor is mostly found in blinking state. It moves as the user writes or deletes something. Command A command is an executable instruction. It may have one or more parameters. Output on command execution is shown inline on the screen. When output is produced, command prompt is displayed on the next line. Graphical User Interface. Graphical User Interface provides the user graphical means to interact with the system. GUI can be combination of both hardware and software. Using GUI, user interprets the software. Typically, GUI is more resource consuming than that of CLI. With advancing technology, the programmers and designers create complex GUI designs that work with more efficiency, accuracy and speed. GUI Elements. GUI provides a set of components to interact with software or hardware. Every graphical component provides a way to work with the system. A GUI system has following elements such as Window An area where contents of application are displayed. Contents in a window can be displayed in the form of icons or lists, if the window represents file structure. It is easier for a user to navigate in the file system in an exploring window. Windows can be minimized, resized or maximized to the size of screen. They can be moved anywhere on the screen. A window may contain another window of the same application, called child window. Tabs If an application allows executing multiple instances of itself, they appear on the screen as separate windows. Tabbed Document Interface has come up to open multiple documents in the same window. This interface also helps in viewing preference panel in application. All modern web browsers use this feature. Menu Menu is an array of standard commands, grouped together and placed at a visible place usually top inside the application window. The menu can be programmed to appear or hide on mouse clicks. Icon An icon is small picture representing an associated application. When these icons are clicked or double clicked, the application window is opened. Icon displays application and programs installed on a system in the form of small pictures. Cursor Interacting devices such as mouse, touch pad, digital pen are represented in GUI as cursors. On screen cursor follows the instructions from hardware in almost real time. Cursors are also named pointers in GUI systems. They are used to select menus, windows and other application features. Application specific GUI components. A GUI of an application contains one or more of the listed GUI elements Application Window Most application windows uses the constructs supplied by operating systems but many use their own customer created windows to contain the contents of application. Dialogue Box It is a child window that contains message for the user and request for some action to be taken. For Example Application generate a dialogue to get confirmation from user to delete a file. Text Box Provides an area for user to type and enter text based data. Buttons They imitate real life buttons and are used to submit inputs to the software. Radio button Displays available options for selection. Only one can be selected among all offered. Check box Functions similar to list box. When an option is selected, the box is marked as checked. Multiple options represented by check boxes can be selected. List box Provides list of available items for selection. More than one item can be selected. Other impressive GUI components are Sliders. Combo box. Data grid. Drop down list. User Interface Design Activities. There are a number of activities performed for designing user interface. The process of GUI design and implementation is alike SDLC. Any model can be used for GUI implementation among Waterfall, Iterative or Spiral Model. A model used for GUI design and development should fulfill these GUI specific steps. GUI Requirement Gathering The designers may like to have list of all functional and non functional requirements of GUI. This can be taken from user and their existing software solution. User Analysis The designer studies who is going to use the software GUI. The target audience matters as the design details change according to the knowledge and competency level of the user. If user is technical savvy, advanced and complex GUI can be incorporated. For a novice user, more information is included on how to of software. Task Analysis Designers have to analyze what task is to be done by the software solution. Here in GUI, it does not matter how it will be done. Tasks can be represented in hierarchical manner taking one major task and dividing it further into smaller sub tasks. Tasks provide goals for GUI presentation. Flow of information among sub tasks determines the flow of GUI contents in the software. GUI Design implementation Designers after having information about requirements, tasks and user environment, design the GUI and implements into code and embed the GUI with working or dummy software in the background. It is then self tested by the developers. Testing GUI testing can be done in various ways. Organization can have in house inspection, direct involvement of users and release of beta version are few of them. Testing may include usability, compatibility, user acceptance etc. GUI Implementation Tools. There are several tools available using which the designers can create entire GUI on a mouse click.
