Question 29

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.

Question 30

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.

Question 31

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.

Question 32

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.

Question 33

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

E) "Don't make me think"!

Question 34

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

Question 35

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.

Question 36

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

Question 37

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

Question 38

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.

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.

Question 40

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

Question 41

A significant drawback of a printed report is the inability of the information to be further manipulated (i.e., sorted).

Question 42

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.

Question 43

Messages are the way in which the system responds to a user and informs him or her of the status of the interaction; they should be clear, concise, complete, grammatically correct, free of unfamiliar jargon, and avoid confusing negatives.

Question 44

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.

Question 45

In order for managers to receive all the information needed to support the task for which it was designed, the report should provide all the information available on the subject and allow the managers to select that which they wish to use.

Question 46

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.

Question 47

Input design means designing the screens used to enter the information, as well as any forms on which users write or type information (e.g., time cards, expense claims).

Question 48

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.

Question 49

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.

Question 50

The goal of the output mechanism is to simply and easily capture accurate information for the system, typically by using on-line or batch processing, capturing data at the source, and minimizing keystrokes.

Question 51

The goal of the navigation system is to make the system as simple as possible to use; a good navigation component is one the user never really notices because it functions the way the user expects.

Question 52

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

Question 53

A heuristic evaluation involves members of the project team individually working through the interface design prototype to examine each interface to see that it satisfies each design principle on a formal checklist.

Question 54

The goal of the input mechanism is to present information to users so they can accurately understand it with the least effort, usually by understanding how reports will be used and designing them to minimize information overload and bias.

Question 55

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."

Question 56

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

Question 57

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

Question 58

Analysts often set out to introduce bias into the design of a report by sorting the information alphabetically or chronologically.

Question 59

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.

Question 60

A drop-down box displays selected items in a one-line box that opens to reveal a list of choices. Common applications include a list of the 50 states and the selection of a printer from a list of 12 available.

Question 61

You should only consider whether customers could find materials in your social media website but not search engines.

Question 62

Ease of use and ease of learning are important interrelated aspects of the user experience design principle.

Question 63

Quarters, Inc. is a company that sells maps of the U.S.A. that have pre-fitted holes corresponding to the recently released quarters with state emblems on the back. The maps are display cases and collectors guides for families or individuals participating in the program. The marketing manager would like to increase sales of the maps over the Internet. Currently the company has a web presence, but it is not able to handle purchases. As the IS manager you have been assigned the new "selling maps over the Internet project." Describe the three types of interface design prototypes and make a recommendation on the appropriate prototyping technique you would use.

Question 64

Content awareness is the user interface design principle that recognizes that if the user is experienced and well aware of the content on the screens, then the design of the screen can be simplified to take advantage of that awareness.

Question 65

Describe the typical layout areas for a standard screen, a Web screen, and a report screen.

Question 66

What are the three interface design prototyping techniques? Identify the three techniques, define each, and determine what conditions or situation would be best suited for each.

Question 67

Use scenarios are developed and used during the evaluation of the interface as a check on what could go wrong.

Question 68

When designing user interface for mobile computing applications, you should not reuse patterns that have been used for mobile devices.

Question 69

One of the rules for designing multilingual user interface is to keep the writing short and straightforward.

Question 70

Messages should require the user to acknowledge them, rather than being displayed for a few seconds and then disappearing, with the exception of delay in processing messages, which should disappear once the delay has passed.

Question 71

What are the six User Interface Design Principles? Identify each principle and provide a description for each.

Question 72

Pull-based approach can be used together with push-based approach for designing social media websites.

Question 73

Question 75

Quarters, Inc. is a company that sells maps of the U.S.A. that have pre-fitted holes corresponding to the recently release quarters with state emblems on the back. The maps are display cases and collectors guides for families or individuals participating in the program. Six months ago the marketing manager requested a new system that would allow retailers of the maps to order them in packs of fifty over the Internet. Three retailers are local and have volunteered to participate in a half-day evaluation of the new system. The new web-based system is almost complete. As the IS testing manager you have been assigned the task of testing the new system. Describe the four methods for interface evaluation and make a recommendation on the appropriate method or methods that would best fit the system described.

Question 76

One of the challenges of designing user interface for mobile computing applications is that the device may be used everywhere.

Question 77

With batch processing (sometimes called transaction processing), each input item is entered into the system individually, usually at the same time as the event or transaction prompting the input.

Question 78

One of the principles for common sense based user interface design is "Don't make me think!"

Question 79

Content awareness is the user interface design principle that requires that the screen design make it clear to the user what content is being displayed.

Question 80

Research suggests that in an ideal world, any one menu should contain no more than eight items, and it should take no more than two mouse clicks or keystrokes from any menu to perform an action (three from the main menu starting a system).
