Concept of User Interface The user interface is the part of the system that you see, hear and feel (look and feel) Other parts of the system are hidden to you, for instance the database where information is stored. Although users don’t see the hidden parts, they imagine to some extent what is going on ’behind the screen’. Examples When you use a computer, you give it orders, usually by means of the mouse and the keyboard. The computer replies, usually by showing something on the screen or making sounds. Sometimes the situation seems reversed the computer gives you instructions and. | Overview of User Interface Design Dr. Lam Thu BUI Software Engineering Department Textbook: User interface design - A software engineering perspective Some figues of this presenation are copyrighted by Pearson Education.

I. Concept of User Interface The interaction with the computer takes place through the user interface. In a standard PC, the user interface consists of the screen, keyboard, mouse and loudspeaker (Figure ). In more advanced systems, the interface may include Voice input through a microphone; Special buttons, lights and displays; Electronic gloves that can feel the movements of your fingers; and Eye sensors that can detect where you are looking at the screen.

User interfaces Accounting system Technical interfaces Factory Slide Technical Interfaces A computer system may have other interfaces than the user interface. Interfaces to other computer systems, for instance an account system. Interfaces to physical processes, for instance temperature sensors, valves, etc. As an example, a chemical factory is computer controlled. The computer system measures the temperature, pressure, etc., and controls the chemical process by opening and .
