Q41.
In the context of consistency, what can be expressed in terms of the form of input expressions or output responses?

a.

The level of support provided to the user in determining successful achievement and assessment of goals.

b.

The likeness in behavior arising from similar situations or similar task objectives.

c.

The user's ability to apply knowledge from one situation to another situation that is similar in some way.

d.

The meaning of actions in some conceptual model of the system.

Discuss
Answer: (d).The meaning of actions in some conceptual model of the system. Explanation:In the context of consistency, the form of input expressions or output responses can be expressed with respect to the meaning of actions in some conceptual model of the system.
Q42.
Provide an example of consistency in the design of a word processor's user interface.

a.

Using color-coded warnings for different types of alerts in an aircraft's warnings panel.

b.

Providing arrow keys on the keyboard to indicate directionality for operations in a word processor.

c.

Using consistent keys on the keyboard to articulate operations in terms of movements up, down, left, or right in the plane of the display.

d.

Using a metaphor of a typewriter to make a word processor's user interface more familiar to users.

Discuss
Answer: (c).Using consistent keys on the keyboard to articulate operations in terms of movements up, down, left, or right in the plane of the display. Explanation:In the example of a word processor, consistency is demonstrated by using consistent keys on the keyboard to articulate operations in terms of movements up, down, left, or right in the plane of the display.
Q43.
What does the principle of "Dialog initiative" refer to in the context of interaction between the user and the system?

a.

The ability of the system to initiate all dialog and request information from the user.

b.

The system's control over the dialog, allowing the user to initiate any action towards the system.

c.

The cooperative editing of a document by two people at the same time.

d.

The user's ability to offer any input action at any time for maximum flexibility.

Discuss
Answer: (a).The ability of the system to initiate all dialog and request information from the user. Explanation:The principle of "Dialog initiative" refers to the ability of the system to initiate all dialog and request information from the user.
Q44.
Which type of dialog hinders flexibility from the user's perspective?

a.

System pre-emptive dialog

b.

User pre-emptive dialog

c.

Cooperative editing dialog

d.

Safety-oriented dialog

Discuss
Answer: (a).System pre-emptive dialog Explanation:From the user's perspective, a system pre-emptive dialog hinders flexibility, as the user is simply responding to requests for information initiated by the system.
Q45.
In what situation might a system pre-emptive dialog be necessary or desirable?

a.

In a cooperative editor where two people edit a document at the same time.

b.

When the user is about to land an aircraft and certain safety measures must be enforced.

c.

When the user needs maximum flexibility to offer any input action at any time.

d.

In a graphical user interface where the user has control over the system's actions.

Discuss
Answer: (b).When the user is about to land an aircraft and certain safety measures must be enforced. Explanation:A system pre-emptive dialog might be necessary or desirable when the user is about to land an aircraft, and certain safety measures must be enforced to prevent potentially serious damage or accidents.
Q46.
What can designers do to minimize the likelihood that the user will be prevented from initiating some task at a time when they wish to do so in a completely user pre-emptive dialog?

a.

Design the system to be entirely user-driven with no system-initiated dialog.

b.

Limit the user's ability to pre-empt the system to avoid losing track of tasks.

c.

Have a good understanding of the sets of tasks the user is likely to perform and how those tasks are related.

d.

Implement cooperative editing features for document collaboration.

Discuss
Answer: (c).Have a good understanding of the sets of tasks the user is likely to perform and how those tasks are related. Explanation:To minimize the likelihood that the user will be prevented from initiating some task at a time when they wish to do so in a completely user pre-emptive dialog, designers should have a good understanding of the sets of tasks the user is likely to perform and how those tasks are related.
Q47.
What is the definition of a thread in the context of the user-system dialog?

a.

A coherent subset of the dialog that relates to a given user task.

b.

A combination of multiple modalities of communication.

c.

An interleaved multi-threading between separate tasks.

d.

A temporal overlap between separate tasks within the dialog.

Discuss
Answer: (a).A coherent subset of the dialog that relates to a given user task. Explanation:In the context of the user-system dialog, a thread refers to a coherent subset of the dialog that relates to a specific user task. It represents a sequence of interactions and responses between the user and the system that are focused on achieving a particular goal or completing a task. Multi-threading allows for different threads to occur simultaneously or in an interleaved manner, supporting concurrent interaction and task management.
Q48.
What does multi-threading of the user-system dialog allow?

a.

Sequential communication of information pertaining to separate tasks.

b.

Simultaneous communication of information pertaining to separate tasks.

c.

A fusion of input and output channels in a single expression.

d.

A mixing of modalities to form separate input or output expressions.

Discuss
Answer: (b).Simultaneous communication of information pertaining to separate tasks. Explanation:Multi-threading of the user-system dialog allows for simultaneous communication of information pertaining to separate tasks. This means that the user can engage in interactions related to different tasks or goals at the same time, without having to complete one task before moving on to another. This enhances the flexibility of the interactive system and improves user productivity by enabling parallel task handling.
Q49.
What is an example of concurrent multi-threading in a multi-modal dialog?

a.

Opening a window with a double click on an icon.

b.

Combining textual and audible components in an error warning message.

c.

Editing a program while receiving an audible beep for a new email message.

d.

Using different windows to represent different tasks in a windowing system.

Discuss
Answer: (c).Editing a program while receiving an audible beep for a new email message. Explanation:An example of concurrent multi-threading in a multi-modal dialog is when a user is editing a program while simultaneously receiving an audible beep for a new email message. In this scenario, the user is engaged in two separate tasks: editing the program and checking email. The audible beep serves as a concurrent input, notifying the user about the arrival of a new email message while they continue their editing task.
Q50.
What dimension characterizes how separate modalities are combined to form a single input or output expression in a multi-modal system?

a.

Concurrent multi-threading

b.

Fused modality

c.

Interleaved multi-threading

d.

Multi-modality dialog

Discuss
Answer: (b).Fused modality Explanation:The dimension that characterizes how separate modalities are combined to form a single input or output expression in a multi-modal system is called "fused modality." Fused modality refers to the mixing of multiple channels of communication to create a cohesive and integrated input or output. An example of fused modality is an error warning message, which typically contains both a textual message and an audible beep to provide both visual and auditory feedback to the user.
