Exam 10: Human Computer Interaction Layer Design

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).

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.

Analysts must assume that users have not read the manual, have not attended training, and do not have external help readily available. To confront these realities, navigation controls must be designed with three basic principles. Identify and define these three principles. Provide an example for each.

Discuss the problem of bias with regard to graphical outputs.

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

What are the six suggestions to address the mobile computing challenges?

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.

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

_____ assures the interface will act as the users expect, while _____ assures it will look pleasing.

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."

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

Discuss three ways a system designer can improve the usability of the system's reports?

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

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

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

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

The Dean of Admissions at State University would like to have an online application process for all prospective students. The online application will have the following field: first, middle, and last name; street, city, state, and zip address; phone; date of birth; and social security number. What types of input validation would you perform on each field? Support your answer.

Laura sorts the information on all of her reports into alphabetical order, which makes it very hard to notice the X, Y, or Z. By sorting the information in this way Laura has introduced _____ into the manager's decision process.

Discuss three design principles that can improve the usability of menus.

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 __________.
