The document discusses various topics related to human interfaces and multimedia. It contains several multiple choice questions about appropriate considerations for designing user interfaces that support both keyboard and mouse users, the best file format for distributing printable forms electronically, and concepts related to universal design. It also asks questions about standards for compressing still images, explanations of virtual reality and hypermedia, and identifying MP3 as a file compression format for audio data.
Human Interface & Multimedia

- 2. 1. When a GUI screen is designed for users who are both familiar with keyboard operation and users who are not, which of the following is the most appropriate consideration to realize a user interface with good usability? a) Minimizing the number of items for keyboard entry, and having users select as many items as possible from lists using a mouse b) Providing both mouse and keyboard interfaces for frequently used operations c) Enabling frequently used operations to be executed by double-clicking the mouse d) Grouping together important items, such as mandatory items, irrespective of the format of the data entry sheet, in order not to cause a lack of input
- 3. 2. A company has different kinds of forms that must be submitted by paper. The company wishes to provide these forms as electronic files on the Web bulletin board system within its intranet, and make them available to all employees. Since many of the forms use more than one font, and/or include diagrams and tables, the forms must be printable without being affected by the user’s software environment. Which of the following is the most appropriate data format? a) HTML format b) PDF format c) Text data format d) Data format for a word- processing software
- 4. 3. A GUI screen contains a candidate list from which a user can select an item. Which of the following is an appropriate case to adopt this data entry method? a) Candidates consist of only a few predetermined values. b) Candidates consist of many different values. c) Input data needs to be edited. d) Data, like a sentence, that does not have a constant value needs to be entered.
- 5. 4. Which of the following is an appropriate policy for designing data entry screens? a) Related input items should be placed close to each other, in order to improve ease of operation on the screen. b) A method of entering commands should be provided, in order to ensure ease of operation even for entry-level users. c) A common message “Input Error” to all data entry errors should be displayed on the screen. d) Detailed directions for use should be displayed on the screen, in order to ensure ease of operation for users.
- 6. 5. Which of the following is an appropriate concept of universal design? a) Ensuring that, once a product is designed, the design remains usable without being changed for a long period of time b) Ensuring that products keep the same levels of performance and quality regardless of where they are manufactured in the world c) Making the design as simple and easy as possible in order to reduce the manufacturing cost d) Making products available to many people regardless of differences in age, culture, and ability as well as whether disability is present

- 8. 1. Which of the following is an international standard for a compression method for still (or static) images? a) BMP b) JPEG c) MPEG d) PCM
- 9. 2. Which of the following is the most appropriate explanation of virtual reality? a) Improving the GUI not by displaying an image gradually from top to bottom, but by first displaying a coarse mosaic- like image, and then by gradually increasing the sharpness of the image b) Enabling computer-simulated objects and spaces to be perceived like the real world by using computer graphics or other techniques c) Conducting computer simulations instead of, among others, the wind-tunnel test used for the design of cars and airplanes d) Combining images of separately shot scenery and people to create an image that is different from the real world
- 10. 3. Which of the following can provide accessible linkage between information items represented in text, still images, video, sound, music, and other forms so that associated information can be reached by visiting one link after another? a) Graphical user interface b) Groupware c) Cyberspace d) Hypermedia
- 11. 4. Which of the following is an appropriate explanation of MP3 that is used as a multimedia file format? a) File compression format for G4 facsimile communication data b) File compression format for audio data c) File compression format for color image data d) File compression format for digital video data
