Question 1

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.

Question 2

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

Accepted Answer

Novice users prioritize ease of use to quickly learn and operate the system, while expert users may focus more on efficiency and advanced features.

Question 3

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 4

A tool bar is a list of commands at the top of the screen that are always present on the interface and may drop down immediately below another menu and disappear after one use.

Accepted Answer

A toolbar typically consists of graphical buttons and icons that provide a quick way to access features or functions within a software program. Unlike menus that may drop down and disappear after one use, toolbars are usually visible and accessible at all times while using the program.

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

Interface evaluation should be performed while the system is being designed so that any major design problems can be identified and corrected before the time and cost of programming has been spent on a weak design.

Accepted Answer

Interface evaluation is an important step in the design process to identify any major design problems that may affect the software development process. Performing interface evaluation at the design stage allows designers to identify and correct any major design problems before the time, and cost of programming has been spent on a poor design. Therefore, the statement is true.

Question 7

The advantage of direct manipulation is that it permits the user to enter extensive data by keystroke and allows the user to size objects within three keystrokes.

Accepted Answer

The statement is false. The advantage of direct manipulation is that it allows the user to manipulate graphical objects directly without the need for complex commands or programming. It typically involves using a mouse, touch screen, or other input device to directly interact with on-screen elements, rather than relying on keyboard inputs. While direct manipulation can make it easier to interact with graphical interfaces, it does not necessarily allow for extensive data entry by keystroke or quick sizing of objects with only three keystrokes.

Question 8

The interface standards, the basic design elements that are common across the individual screens, forms, and reports within the system, must be identical for different parts of the system, hence the name "standards."

Accepted Answer

Interface standards refer to guidelines that ensure consistency across a system, but they do not necessarily mean that every element must be identical; they allow for variations to suit different parts of the system while maintaining overall coherence.

Question 9

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

Accepted Answer

This is true as white space helps to create a clean and organized design, making it easier for the reader to read and understand the content. It also helps to draw attention to important elements on the page.

Question 10

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

Accepted Answer

A use scenario is a detailed description of the steps that a user performs to accomplish a specific task or goal using a software application, product, or service. It helps designers and developers understand user needs, behaviors, and expectations, and design user interfaces and interactions that are intuitive, efficient, and effective.

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

An interface metaphor is indeed 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.

Question 12

The grammar order of the navigation controls may be random (object-action or action-object) throughout an application.

Accepted Answer

Consistency in the grammar order of navigation controls (e.g., object-action or action-object) is crucial for usability, helping users predict and understand how to interact with the application.

Question 13

The interface standard that describes the general appearance of all the screens in the information system and the paper-based forms and reports that are used/developed by the system is the interface templates.

Accepted Answer

Interface templates define the consistent look and feel of user interfaces across an information system, including screen layouts, controls, and the design of paper-based forms and reports, ensuring a cohesive user experience.

Question 14

A few rule you should follow to design multilingual user interfaces. Which one in the following list is NOT one of the rules?

Accepted Answer

Using large fonts is not a strict rule for designing a multilingual user interface, although it may be beneficial for accessibility and legibility. The other three rules listed (keeping writing short and simple, avoiding humor/jargon/slang/etc., and using good grammar) are all important considerations for creating a user-friendly and culturally-sensitive interface for multilingual users.

Question 15

A menu bar is often a second-level menu that pops up, floats over the screen, and disappears after one use.

Accepted Answer

A menu bar is a static bar that typically sits at the top of the screen and displays the main categories of options available in an application, such as File, Edit, View, etc. It does not pop up or disappear after one use.

Question 16

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

Screen and frame titles, well-defined areas, and good field labels are all ways to make users aware of the content on the interface. This makes it easier for them to understand what information they are working with and how to interact with it.

Question 17

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 __________.

Accepted Answer

The push-based approach refers to the server sending information to users periodically, without the user having to actively seek it out. This can include notifications, updates, or recommendations based on their activity on the site. Option A describes a pull-based approach, where the user has to actively click buttons to retrieve information. Option C also describes a pull-based approach, where the user must come to the site to find information. Option D refers to a specific mechanism for automated retrieval of information, but it does not describe the push/pull approach. Option E is also incorrect, as it suggests that the user must actively access the server to retrieve information that has been saved for them.

Question 18

The final step in the user interface design process, interface evaluation, usually does not yield any improvements, because by that stage of the design process, all of the "bugs" will normally have been removed from the system.

Accepted Answer

This statement is false. Interface evaluation is crucial in identifying any remaining usability issues and gathering user feedback to further improve the design. Evaluating the interface can lead to significant improvements in the user experience.

Question 19

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 20

Analysts must assume that users have read the manual, have attended the training classes, and have external help nearby.

Accepted Answer

Analysts cannot assume that users have all the necessary knowledge and resources. It is their responsibility to provide adequate support and assistance.
