Practical work 3 Human-computer interaction

Human-computer interface (HCI) The means of communication between a human user and a computer system, referring in particular to the use of input/output devices with supporting software. Human-computer interface (HCI) The means of communication between a human user and a computer system, referring in particular to the use of input/output devices with supporting software. Devices of increasing sophistication are becoming available to mediate the human-computer interaction. These include graphics devices, touch-sensitive devices, and voice-input devices. They have to be configured in a way that will facilitate an efficient and desirable interaction between a person and the computer. 

command line interface, text interface, graphic interface A user interface is the method by which the user and the computer exchange information and instructions. There are three main types: command-line, menu driven and graphical user interface (GUI).

Command-line interfaces A command-line interface allows the user to interact with the computer by typing in commands. In the early days of personal computers, all PCs used command-line interfaces. An example of a common command driven interface is MS-DOS. The MS-DOS command to display all files on c:\ would be: dir c:\

Menu driven interfaces 1. Simple menu The user is offered a simple menu from which to choose an option. One menu often leads to a further menu. Part of the screen may have an instruction followed by a numbered list of options to choose from.

Menu driven interfaces 2. Full screen menu A full screen menu takes up the entire screen.

Menu driven interfaces 3. Menu bar A menu bar is the set of options at the top of the screen. When an option is chosen a drop-down menu may be offered.

Graphical user interface  Graphical user interface is sometimes shortened to GUI. The user chooses an option usually by pointing a mouse at an icon representing that option. Windows XP, Windows Vista, Apple OSX and Ubuntu all have graphical user interfaces.
