Question 1

Jamal is creating a user interface.He wants what he calls an 'oops' button on every screen and form (or an 'undo' button).This is a good design consideration.

Accepted Answer

Having an 'oops' or 'undo' button on every screen and form is a good design consideration as it provides users with the ability to easily reverse any accidental actions or mistakes they may have made.

Question 2

When creating navigational controls,you should either not display a command that cannot be used or 'gray' it out (where it shows,but cannot be used).

Accepted Answer

This is correct as it aligns with the principle of not displaying irrelevant or inactive controls to avoid confusing the user.

Question 3

Barcode readers are one way of doing batch processing.

Accepted Answer

Barcode readers are typically used for real-time data capture and processing, not batch processing, which involves processing data in large groups at a scheduled time.

Question 4

Radio buttons allow users to select multiple options.

Accepted Answer

Radio buttons allow users to select only one option from a group of options. Checkboxes allow for multiple selections.

Question 5

Formal usability testing can be very expensive.

Accepted Answer

Formal usability testing often requires recruiting and compensating participants, renting facilities, and hiring trained facilitators, which can result in high costs.

Question 6

Capturing data at the source is highly recommended.

Accepted Answer

Capturing data at the source means collecting data directly where it is generated or originated. This method ensures data accuracy, completeness, and timeliness. It also reduces errors and duplication, which improves overall data quality. Therefore, it is recommended to capture data at the source as opposed to obtaining it from a secondary source.

Question 7

The most common type of navigation system today is the menu.

Accepted Answer

The menu is the most common type of navigation system used in websites, apps and software programs today. It allows users to easily access different pages or features by selecting from a list of options that are typically displayed in a dropdown or sidebar menu. Other types of navigation systems include tabs, breadcrumbs, and search bars.

Question 8

Menus frequently have 'hot keys' - like ctrl-F for find;ctrl-X for cut.

Accepted Answer

Menus do frequently have hot keys or keyboard shortcuts to perform common actions, such as Ctrl-F for Find or Ctrl-X for Cut.

Question 9

Delay messages frequently are only icons (like hourglasses or revolving circles when the system is busy).

Accepted Answer

Delay messages are often represented by icons, such as hourglasses or revolving circles, to indicate that the system is busy processing the message and the user should wait.

Question 10

An error message should use humor like "Hey - are you sure you want to do this - it might hurt you more than it hurts me".

Accepted Answer

While it may seem like a good idea to use humor in an error message, it can often come across as unprofessional and insensitive. It's important to convey the error message clearly and with empathy, rather than making light of the situation.

Question 11

Confirmation messages might be used when a user is about to permanently delete a file.

Accepted Answer

Confirmation messages are commonly used to double-check with the user before carrying out a permanent or irreversible action, such as deleting a file.

Question 12

Acknowledgement messages should be used rarely as they can become annoying.

Accepted Answer

Acknowledgement messages should only be used when necessary and not sent unnecessarily as they can clutter up communication channels and become irritating for the recipient.

Question 13

The basic goal of input design is to capture accurate information for the system simply and easily.

Accepted Answer

The basic goal of input design is to capture accurate information for the system simply and easily. It is important for the input design to be user-friendly and efficient in order to minimize errors and maximize productivity.

Question 14

Magnetic stripe readers (like for credit cards)are a good way to capture data at the source.

Accepted Answer

Magnetic stripe readers are designed to read and capture data from the magnetic stripe on credit cards, making them a reliable way to capture data at its source.

Question 15

When creating navigational controls for an interface,analysts should assume that all users will (a)be given training;(b)have a user's manual for the new interface and (c)will have experts available to help them (like help desk personnel).

Accepted Answer

Analysts should not assume that all users will have training, a user's manual or experts available to assist them. It is important to design navigational controls that are intuitive and require minimal training or assistance.

Question 16

Error messages inform the user that he or she has attempted to do something that cannot be done.They should explain the situation and suggest corrective action.

Accepted Answer

Error messages are designed to provide feedback and guidance to the user about the nature of the error or problem they have encountered, and offer suggestions for resolving it.

Question 17

Research shows that in an ideal world a menu should contain no more than four items and submenus should contain no fewer than six items.

Accepted Answer

Research has not provided a clear set number for the ideal number of items in a menu or submenu. It can vary depending on the context and design goals. However, it is generally recommended to limit the number of options in a menu or submenu to avoid overwhelming the user.

Question 18

A 'hierarchical evaluation' examines the interface prototype by comparing it to a set of 'hierarchies' or principles for interface design (i.e.the prototype is compared to a list of expectations).

Accepted Answer

A 'hierarchical evaluation' typically refers to a method of evaluating a system by breaking it down into its component parts or levels, rather than comparing it to a set of design principles or expectations.

Question 19

Messages are the way in which the system responds to a user and informs him or her of the status of the interaction.

Accepted Answer

Messages are indeed used by a system to communicate with the user and inform them about the status of the interaction.

Question 20

The first principle of designing navigational controls is to prevent users from making mistakes.

Accepted Answer

The first principle of designing navigational controls is to prevent users from making mistakes, as it can lead to frustration and confusion. By structuring the navigation in a clear and intuitive way, users can easily understand how to move through the website or application without accidentally clicking on the wrong button or getting lost.
