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.

True

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.

True

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.

True

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.

True

Which of the following interface evaluation techniques involves a highly structured assessment of the users' interaction with the system?

Usability testing

Several rules exist when designing multilingual user interfaces. Which of the following is NOT one of the rules?

Use large fonts.

Juan is designing a user interface for the data-entry clerks in the marketing department. In an interview with the department manager, Juan has learned that the department has frequent turnover and that there is very little money for training. What two interface design principles would be best to recommend to Juan to emphasize in his design?

User experience and consistency

A(n) _____ check is a type of input validation that determines if several fields have been entered before the form can be processed.

completeness

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?

consistency

The user interface design principle that places an emphasis on the user's ability to always know where he/she is in the system and what information is being displayed is _____.

content awareness

Moving files by dragging and dropping is an example of _____ navigation controls.

direct manipulation

Novice users prefer _____ while expert users prefer _____.

ease of learning, ease of use

As an addition to a regular report, a(n) _____ report may help the user understand the change in comparison values over time or show proportions that are relative to the whole.

graph

The fundamental part of the user interface that permits the system to capture information is the _____ mechanism.

input

The _____ design principle requires that a report not provide all the available information, only the information that is needed.

manage information load

If real-time information is required by the information system, then the appropriate input processing mechanism is _____.

online processing

The fundamental part of the user interface that provides information from the system to the user is the _____ mechanism.

output

A(n) _____ check ensures that the numeric data entered is within the correct minimum or maximum values.

range

One of the guidelines for designing user interfaces for social media Web sites is to make sure you understand the difference between push and pull approaches. The push-based approach is __________.

the server sends information to users periodically

Krug's three design principles are also important in designing the user interfaces of mobile computing systems, especially the first one which is ________________

use the unique features from the device

A(n) _____ shows how all the screens, forms, and reports are related, and how the user moves from one to another.

window navigation diagram

Which of the following is the most important principle of input design?

Capture input electronically as close to the source as possible.

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.

False

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.

False

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.

False

The ideal computer system permits users to enter invalid data into the system. This data is later inexpensively identified, and someone is notified to resolve the information problem.

False

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."

False

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.

False

Which of the following ways of enabling users to communicate with the system is most commonly used?

Natural languages

Steve Krug provides us with a set of guiding principles for Web usability. Find one of the principles in the following list.

The user should never have to think about how to navigate the user interface.
