Question 1

The three fundamental parts of the system interface are the navigation mechanism, the input mechanism, and the output mechanism, all of which are closely intertwined.

Accepted Answer

The statement is true. The navigation mechanism is used to move around the system or application, the input mechanism is used to interact with the system or application, and the output mechanism is used to display information to the user. All three are essential components of the system interface.

Question 2

The first step in the user interface design process is "interface design prototyping."

Accepted Answer

The first step in the user interface design process is typically "user research" or "requirements gathering," not "interface design prototyping."

Question 3

Steve Krug provides us with a set of guiding principles for web usability. Find one of the principles in the following list
A) The user should never have to think about how to navigate the user interface.
B) Using more clicking instead of typing.
C) Using more texts in the interface
D) Using more voice recognition feature as possible.
E) Be consistent to other similar applications

Accepted Answer

The principle of "the user should never have to think about how to navigate the user interface" is mentioned in Steve Krug's book as one of the key guiding principles for web usability. The goal is to make the website or application intuitive and easy to use so that users can focus on their goals and tasks without being distracted by confusing or complicated navigation.

Question 4

All forms and reports need a minimal amount of white space that is intentionally left blank.

Accepted Answer

All forms and reports should have a proper layout and design that includes white space intentionally left blank to allow the eye to rest and make the document easier to read and understand.

Question 5

Most user interface designers follow the minimal user effort principle by permitting users to go from the main menu of the system to the information or action need in no more than five mouse clicks or five keystrokes.

Accepted Answer

The answer of Most user interface designers follow the minimal...

Question 6

Using the word "client" repeatedly, instead of interchanging it with the word "customer" is an example of the interface design principle for minimal user effort.

Accepted Answer

Using the same term consistently reduces cognitive load and confusion, aligning with the principle of consistency, not minimal user effort. Minimal user effort focuses on reducing the steps or actions required from the user.

Question 7

A few rule you should follow to design multilingual user interfaces. Which one in the following list is NOT one of the rules?
A) Keep the writing short and simple.
B) Avoid humor, jargon, slang, clichés, puns, analogies, and metaphors.
C) Use good grammar.
D) Use large fonts.

Accepted Answer

The rule "Use large fonts" is not one of the rules for designing multilingual user interfaces. However, it is important to use a font size that is easy to read and can accommodate different alphabets and scripts.

Question 8

A(n) _____ check ensures that combinations of data are valid, for example, does the zip code of an address correspond to the correct state name.
A) completeness
B) consistency
C) database
D) format
E) range

Accepted Answer

Consistency checks ensure that data elements are logically consistent with one another. In the given example, a consistency check would ensure that a zip code matches with its corresponding state name in the database.

Question 9

Probably the single most important factor in making a system simple to use is consistency because it enables users to predict what will happen; once they can interact with one part of the system, they will know how to interact with the rest.

Accepted Answer

Consistency allows users to develop mental models of how the system works, making it easier for them to use and predict how the system will behave. This makes the system more intuitive and less frustrating for users.

Question 10

The use of screen and frame titles, well-defined areas on reports and forms, and good field labels apply to the interface design principle of content awareness.

Accepted Answer

These are all examples of techniques that help make the content on the interface more easily identifiable and understandable by the user, which is the goal of the content awareness principle.

Question 11

An interface metaphor is a concept from the real world that is used as a model to help the user understand the system and enable the user to predict what features the interface might provide.

Accepted Answer

This is a correct definition of interface metaphor.

Question 12

All parts of the interface, whether navigation, input, or output, should provide as much content awareness as possible, but it is particularly important for forms or reports that are used quickly or irregularly.

Accepted Answer

Providing content awareness in all parts of the interface is important, but it is especially important for forms or reports that are used quickly or irregularly, as users may not have the time to learn how to use them effectively.

Question 13

Krug's three design principles are also important to design the user interfaces of mobile computing systems, especially the first one: ________________ .
A) give the mobile context
B) remove all "fluff" from the site
C) try to linearize the content of the application
D) using the unique features from the device
E) "Don't make me think"!

Accepted Answer

The answer of Krug's three design principles are also important...

Question 14

The _____ design principle requires that a report not provide all the available information, only the information that is needed.
A) understand report usage
B) minimize bias
C) manage information load
D) real-time reporting
E) none of the above

Accepted Answer

The design principle that requires a report to only provide the necessary information and avoid overwhelming the reader with unnecessary details is known as managing information load. This ensures that the report is clear, concise, and effective in conveying its message. The other answer choices are related to different principles of report design but do not directly address the issue of information overload.

Question 15

Guidelines for aesthetics require that as much information as possible be squeezed onto a page or a screen with a minimum of white space; this will make the form or report pleasing to the eye and extremely functional.

Accepted Answer

Guidelines for aesthetics actually emphasize the importance of white space and balance in design to achieve visual appeal and ease of use. Squeezing too much information onto a page can make it cluttered and difficult to read or understand.

Question 16

A use scenario is an outline of the steps that the users perform to accomplish some part of their work.

Accepted Answer

This is correct, a use scenario is a description of the steps a user takes to complete a task or achieve a goal within a system or application.

Question 17

Novice and expert users are both usually most concerned with "ease of use" of a new system.

Accepted Answer

The answer of Novice and expert users are both usually...

Question 18

Interfaces should be designed primarily for the inexperienced users who are usually most concerned with ease of use; experienced users will be able to quickly pass over the simpler aspects of the new system.

Accepted Answer

Interfaces should be designed to accommodate both inexperienced and experienced users, ensuring ease of use for beginners while providing efficiency and advanced features for experienced users.

Question 19

One of the guidelines for designing user interfaces for social media website is to make sure you understand the difference between push and pull approaches. The push-based approach is __________.
A) you have to click buttons to get information
B) the server sends information to users periodically
C) the user has to come to the social media website to find information
D) the user setup an agent program to get information from the website
E) the server collects information for the user and store in the server and the user can access it at any time.

Accepted Answer

The push-based approach is when the server sends information to users periodically without the user having to request for it or come to the website to find it.

Question 20

The user interface includes three parts; the input mechanism, the output mechanism, and the reporting mechanism.

Accepted Answer

The user interface typically includes two main parts: the input mechanism (how the user controls the interface) and the output mechanism (how the interface presents information to the user). Reporting mechanisms are considered a function or feature within the broader scope of output mechanisms, not a separate part of the user interface.
