Human Interface Ch 1 assessment test

Suppose you are designing a touch-screen interface for a kiosk in a video rental store. You want to provide the ability for the user to search for a movie and then provide information on where it is located in the store. Which of the following would be the most effective way to improve search performance?

After each letter is typed in, update a browse able list of movies with the names consistent with what the user has typed in so far

One goal in requirements analysis is to ensure proper reliability. However, which of the following is not a responsibility of the human interface designer? Actions must function correctly. Displayed data must reflect the database contents. The software architecture, hardware components, and network support must ensure high availability. Ensure privacy, security and data integrity.

All the above are responsibilities of the designer.

Sara works for a large corporation and spends a great deal of her workday at a computer terminal. Occasionally, she'll perform a series of actions and receive a confusing error message on the screen which will impede her work and not allow her to proceed. At this point, Sara should:

Complain to the designer who did not provide a more convenient mechanism for completing her task.

Designers are encouraged to consider the plasticity of their designs when building a successful interface. What does this mean?

Ensure smooth conversion over diff display sizes, translate into multiple languages, provide compatibility with accessibility support. (All of the above)

T/F Current research in Human-Computer Interaction is largely done by introspection and intuition. Due to the fact that the field is relatively new, there is little need for a scientific method for interface research.

False

T/F There is a significant diversity among humans with regard to physical abilities, backgrounds, cultures and age. However, by simply designing an interface for the average, generic human, people of various types will be able to conform to the design without toil.

False

T/F Designing interfaces to help meet the needs of disabled users will inevitably hurt normal user's productivity.

False

Match type of system Subjective satisfaction is of modest importance. Retention is obtained by frequent use. Operator training time is expensive, so ease of learning is important.

Industrial and Commercial Use

Universal Usability deals with accommodating diverse users by..

Innovative design that allow user controlled flexibility

Some older adults avoid helpful computer-based devices, such as bank terminals, because they are anxious about breaking the device or making an embarrassing mistake. Which of the following would be a good starting point to help alleviate this fear of a bank terminal?

Interview older adults who are nonusers of computers to help understand the source of their anxiety.

One goal in requirements analysis is to ascertain the user's needs. Which of the following methods is the most effective way to serve the user's goals?

Invest a significant amount of time into task analysis to determine what tasks and subtasks must be carried out.

Match type of system Lengthy training periods are acceptable to obtain rapid, error-free performance, even when the users are under stress

Life-Critical Systems

Match type of system Ease of learning, low error rates, and subjective satisfaction are paramount because use is frequently discretionary and competition is fierce.

Office, home and entertainment applications.

Of the five usability measures for practical evaluation, which one is accomplished by interviews and surveys?

Subjective Satisfaction

T/F Subjectively satisfying the user is an important usability measure for determining the effectiveness of an interface.

True

The ability for novice users to evolve into power users is one property of a well-designed interface. Which of the following methods might best allow a graceful evolution from novice to expert? (Select ALL that apply.)

Use a single interface that allows the user to increase the complexity of the display when they feel comfortable. Provide hints and online assistance to users on various ways they can perform a certain task.
