Lesson 7

II. Reading exercises:

Exercise 2

1. A command-driven interface is one in which you type in commands to make the computer do something

2. Their interface is called WIMP (Window, Icon, Mouse, Pointer) and software products for the Macintosh have been design to take full advantage of its features using the interface

3. These three platforms include similar features: a desktop with icons, windows and folders, a printer selector, a file finder, a control panel, various disc accessories

4. The three platforms differ in other areas such as device installation, network connectivity or compatibility with application programs

Exercise 3

1d, 2c, 3a, 4b

Exercise 4

Command choices. On an infinite virtual desktop.

III. Speaking exercises:

Exercise 1

Interface

The user interface is the junction between a user and a computer program. An interface is a set of commands or menus through which a user communicates with a program. It is how you interact with the computer. The term ‘user interface’ refers t the standard procedures the user follows to interact with a particular computer.

User friendly interface

A graphical user interface (GUI) is one in which you select command choices from various menus, buttons and icons using a mouse. It is a user-friendly interface.

Text user interface

Text user interfaces (TUI) share with GUIs their use of the entire screen area and exposure of available commands through widgets like form entry and menus. However, TUIs only use text and symbols available on a typical text terminal, while GUIs typically use high resolution graphics modes. This allows the GUI to present more detailed information and fine-grained direct manipulation.

Zooming user interface

Zooming user interface or zoomable user interface (ZUI, pronounced zoo-ee) is a graphical environment where users can change the scale of the viewed area in order to see more detail or less. A ZUI is a type of graphical user interface (GUI). Information elements appear directly on an infinite virtual desktop (usually created using vector graphics), instead of in windows. Users can pan across the virtual surface in two dimensions and zoom into objects of interest.

Command-driven interface

A command-driven interface is one in which you type in commands to make the computer do something. You have to know the commands and what they do and they have to be typed correctly.

Exercise 2

1.How many common user interfaces are there?

2.Where do information elements appear directly?

3.How do three platforms differ?
