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.

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
