Each serves a specific interaction purpose, such as a trash icon for delete, a volume slider, or a Save dialog. ## Answer A multimedia user interface is made of components through which the user gives input and receives output. The main components are listed below. #### 1. Text Used for titles, labels, menus, instructions and content. Must be readable (font, size, contrast). Example: a heading and a paragraph in a help screen. #### 2. Graphics and images Icons, buttons, pictures, charts and backgrounds. They make the interface attractive and show meaning quickly. Example: a trash can icon for delete. #### 3. Audio Narration, music, sound effects and alert beeps. Gives feedback and guidance. Example: a click sound on pressing a button, or voice instructions. #### 4. Video and animation Show processes and motion and add interest. Needs playback controls. Example: a demonstration clip in a training CD. #### 5. Menus Lists of choices: pull-down, pop-up, cascading and menu bars. Example: the File menu of an editor. #### 6. Buttons and icons Clickable objects that start actions, such as Play, Next and Help. Their look must show that they can be clicked. #### 7. Windows and dialog boxes Separate areas for content, and pop-ups that ask for input or give messages. Example: a Save dialog. #### 8. Hypertext and hypermedia links Linked words, images or buttons that jump to related information. Example: a word in an online encyclopedia linking to a picture. #### 9. Input controls (forms) Text boxes, check boxes, radio buttons, list boxes, sliders and scroll bars to enter data or set values. Example: a volume slider. #### 10. Input and output devices Keyboard, mouse, touch screen, microphone, camera, speakers, and display. They are the physical part of the interface. #### 11. Help and navigation aids Index, search, site map and tutorial help the user move around and find content. ## Check yourself The answer's key points as multiple-choice questions, with the correct option and why. 1. What is the main role of audio as a multimedia interface component? A. To give feedback and guidance, such as a click sound or voice instructions B. To store the user's data permanently C. To let the user jump to related pages D. To show the structure of the screen layout Answer: A. Audio (narration, music, effects, beeps) gives feedback and guidance, e.g. a click sound on pressing a button. (Key point: Role of audio) 2. A word in an online encyclopedia that jumps to a related picture when clicked is an example of which component? A. Menu B. Dialog box C. Hypertext/hypermedia link D. Input control Answer: C. Linked words, images or buttons that jump to related information are hypertext/hypermedia links. (Key point: Hypertext and hypermedia links) 3. Which set contains only input controls (forms) used to enter data or set values? A. Speakers, display, microphone B. Index, search, site map C. Text boxes, radio buttons, sliders, scroll bars D. Icons, charts, backgrounds Answer: C. Input controls include text boxes, check boxes, radio buttons, list boxes, sliders and scroll bars, e.g. a volume slider. (Key point: Input controls) 4. What must be true of the look of a button in a multimedia interface? A. It must always play a sound B. It must be hidden until hovered C. It must contain only text D. It must show that it can be clicked Answer: D. Buttons start actions such as Play, Next and Help, and their appearance must make it clear they are clickable. (Key point: Buttons and icons) ## Related in Multimedia System - [Multimedia user interface design process](https://www.bctengineer.com/question.md?key=semester_8%2Fmultimedia_system%3Aui-design-process) — Multimedia System, chapter 6, asked 2× - [Components to build multimedia systems](https://www.bctengineer.com/question.md?key=semester_8%2Fmultimedia_system%3Acomponents-build-multimedia-systems) — Multimedia System, chapter 1 - [Multimedia UI design guidelines](https://www.bctengineer.com/question.md?key=semester_8%2Fmultimedia_system%3Aui-design-guidelines) — Multimedia System, chapter 6, asked 5× ## Related in other subjects - [Components of detail estimate report (road)](https://www.bctengineer.com/question.md?key=semester_7%2Festimating_and_costing%3Adetail-estimate-report-road) — Estimating and Costing, chapter 5 - [File system layout; interface vs implementation](https://www.bctengineer.com/question.md?key=semester_6%2Foperating_system%3Afs-layout-interface-vs-implementation) — Operating System, chapter 5 - [Passive components behavior and application protocols](https://www.bctengineer.com/question.md?key=semester_7%2Frf_and_microwave_engineering%3Amicrowave-components-behavior-protocols) — RF and Microwave Engineering, chapter 1 - [Components of welded plate girder and selection](https://www.bctengineer.com/question.md?key=semester_6%2Fdesign_of_steel_and_timber_structure%3Aplate-girder-components-selection) — Design of Steel and Timber Structure, chapter 7
