SECOND HALF MODULE 3

Question 1

(NOTES) Best Practices for Designing an Interface:

Answer 1

 Keep the interface simple.

 Create consistency and use common UI elements.

 Be purposeful in page layout.

 Strategically use color and texture.

 Use typography to create hierarchy and clarity.

 Make sure that the system communicates what’s happening.

 Think about the defaults.

Question 2

There are three factors that should be considered for the design of a successful user interface;

Answer 2

development factors

visibility factors

acceptance factors.

Question 3

These factors help by improving visual communication. These include: platform constraints, tool
kits and component libraries, support for rapid prototyping, and customizability.

Answer 3

Development factors

Question 4

These factors take into account human factors and express a strong visual identity. These include:
human abilities, product identity, clear conceptual model, and multiple representations.

Answer 4

Visibility factors

Question 5

Included as these factors are an installed base, corporate politics, international markets, and
documentation and training.

Answer 5

acceptance factors

Question 6

This refers to all of the graphical techniques used to communicate the message or context.

Answer 6

Visible language

Question 7

Visible language includes:

Answer 7

 Layout:

 Typography:

 Color and Texture:

 Imagery:

 Animation:

 Sequencing:

 Sound:

 Visual identity:

Question 8

Principles of User Interface Design
There are three fundamental principles involved in the use of the visible language.

Answer 8

 Organize: provide the user with a clear and consistent conceptual structure

 Economize: do the most with the least amount of cues

 Communicate: match the presentation to the capabilities of the user.

Question 9

These are important concepts of organization.

Answer 9

Consistency, screen layout, relationships and navigability

Question 10

Consistency
There are four views of consistency:

Answer 10

internal consistency,

external consistency,

real-world
consistency,

and when not to be consistent.

Question 11

Screen Layout
Three ways to design display spatial layout:

Answer 11

use a grid structure,

standardize the screen layout,

and group related elements.

Question 12

NOTES: Navigability
There are three important navigation techniques:

1. provide an initial focus for the viewer’s attention
2. direct attention to important, secondary, or peripheral items
3. assist in navigation throughout the material.

Question 13

Economize
Four major points to be considered:

Answer 13

simplicity,
clarity,
distinctiveness,
emphasis.

Question 14

This includes only the elements that are most important for communication. It should also be as
unobtrusive as possible.

Answer 14

Simplicity

Question 15

All components should be designed so their meaning is not ambiguous.

Answer 15

Clarity

Question 16

The important properties of the necessary elements should be distinguishable.

Answer 16

Distinctiveness

Question 17

The most important elements should be easily perceived. Non-critical elements should be de-emphasized
and clutter should be minimized so as not to hide critical information.

Answer 17

Emphasis

Question 18

The GUI must keep in balance legibility, readability, typography, symbolism, multiple views, and color or
texture in order to __________ successfully.

Answer 18

communicate

Question 19

display must be easy to identify and interpret, should also be appealing and attractive.

Answer 19

Readability:

Question 20

These includes characteristics of individual elements (typefaces and typestyles) and their
groupings (typesetting techniques). A small number of typefaces which must be legible, clear, and
distinctive (i.e., distinguish between different classes of information) should be used.

Answer 20

Typography

Question 21

provide multiple perspectives on the display of complex structures and processes.

Answer 21

Multiple views

Question 22

This is one of the most complex elements in achieving successful visual communication. Used correctly,
it can be a powerful tool for communication.

Answer 22

color

For notes:(Some advantages for using color to help communication: - emphasize important information - identify
subsystems of structures - portray natural objects in a realistic manner - portray time and progress -
reduce errors of interpretation - add coding dimensions - increase comprehensibility - increase
believability and appeal

There are some disadvantages for using color: - requires more expensive and complicated display
equipment - many not accommodate color-deficient vision - some colors can potentially cause visual
discomfort and afterimages. - may contribute to visual or may lead to negative associations through crossdisciplinary and cross-cultural association.
)

Question 23

Color Design Principles
The three basic principles can also be applied to color:

Answer 23

color organization, color economy, and color
communication.

Question 24

This pertains to consistency of organization. Color should be used to group related items. A
consistent color code should be applied to screen displays, documentation, and training materials

Answer 24

Color organization

Question 25

The second principle of color, _________, suggests using a maximum of 5+/-2 colors where the
meaning must be remembered. The fundamental idea is to use color to augment black-and-white
information, i.e. design the display to first work well in black-and-white.

Answer 25

color economy

Question 26

This suggests using strong contrasts in value and chroma to draw the user’s attention to the
most important information.

Answer 26

Color Emphasis

Question 27

___________ deals with legibility, including using appropriate colors for the central and peripheral
areas of the visual field.

Answer 27

Color communication

Question 28

The importance of color is to communicate. Therefore color codes should respect existing cultural and
professional usage. Connotations vary strongly among different kinds of viewers, especially from different
cultures. Color connotations should be used with great care.

Answer 28

Color Symbolism
