Q21.
What is the purpose of predictability in an interactive system?

a.

To challenge users with unpredictable interactions

b.

To ensure that the system's behavior is completely determined by its state

c.

To prevent users from making mistakes in their interactions

d.

To support users in understanding the consequences of their actions and interactions

Discuss
Answer: (d).To support users in understanding the consequences of their actions and interactions Explanation:The purpose of predictability in an interactive system is to support users in understanding the consequences of their actions and interactions with the system.
Q22.
How does predictability in an interactive system relate to the user's knowledge of the system's behavior?

a.

Predictability requires the user to have deep knowledge of the system's internal workings.

b.

Predictability is achieved when the user can predict future interactions without any prior knowledge.

c.

Predictability is based on the user's knowledge of the interaction history, helping them determine future outcomes.

d.

Predictability relies on the user's ability to adapt to changes in the system's behavior.

Discuss
Answer: (c).Predictability is based on the user's knowledge of the interaction history, helping them determine future outcomes. Explanation:Predictability in an interactive system is based on the user's knowledge of the interaction history, which allows them to determine future outcomes.
Q23.
What does the concept of predictability primarily aim to avoid in interactive systems?

a.

Surprises and unexpected outcomes for the user

b.

User errors and mistakes during interactions

c.

Complex and hard-to-understand interactions

d.

Dependence on deterministic algorithms in the system

Discuss
Answer: (a).Surprises and unexpected outcomes for the user Explanation:Predictability aims to avoid surprises and unexpected outcomes for the user in interactive systems.
Q24.
What is operation visibility in the context of an interactive system?

a.

The ability to see the current state of the system's operations

b.

The visual indication of available operations that can be performed next

c.

The system's ability to recognize user inputs and perform corresponding operations

d.

The user's ability to remember when to perform specific operations

Discuss
Answer: (b).The visual indication of available operations that can be performed next Explanation:Operation visibility refers to how the user is shown the availability of operations that can be performed next in the interface.
Q25.
How does operation visibility support the principle of predictability?

a.

It helps the user remember past interactions and their consequences.

b.

It enables the user to determine the effect of operations on the system.

c.

It encourages the user to explore the system's internal workings.

d.

It allows the user to recognize available operations rather than relying on recall.

Discuss
Answer: (d).It allows the user to recognize available operations rather than relying on recall. Explanation:Operation visibility supports the superiority of recognition over recall in humans by allowing the user to recognize available operations without having to rely on memory recall.
Q26.
Why is operation visibility important in interactive systems?

a.

It allows the user to perform complex operations without prior knowledge.

b.

It prevents the user from making mistakes during interactions.

c.

It helps the user understand the system's internal workings.

d.

It assists the user in knowing which operations can be performed at a given moment.

Discuss
Answer: (d).It assists the user in knowing which operations can be performed at a given moment. Explanation:Operation visibility is important in interactive systems as it helps the user know which operations can be performed at any given moment, reducing the need for memory recall.
Q27.
What does the principle of synthesizability refer to in an interactive system?

a.

The user's ability to predict the effect of future interactions

b.

The user's ability to understand the system's internal state

c.

The ability of the user to assess the effect of past operations on the current state

d.

The ability of the system to change its behavior based on user interactions

Discuss
Answer: (c).The ability of the user to assess the effect of past operations on the current state Explanation:Synthesizability refers to the user's ability to assess the effect of past operations on the current state of the system.
Q28.
What is the role of the principle of honesty in an interactive system?

a.

To ensure that the system is honest in providing accurate information to the user

b.

To promote the user's ability to predict the effect of future interactions

c.

To allow the user to understand the system's internal state and behavior

d.

To provide an observable and informative account of changes in the system's state

Discuss
Answer: (d).To provide an observable and informative account of changes in the system's state Explanation:The principle of honesty ensures that the user interface provides an observable and informative account of changes in the system's state, allowing the user to assess the effects of past operations.
Q29.
What is the difference between immediacy and eventuality in the context of the principle of honesty?

a.

Immediacy requires the user to remember the destination directory, while eventuality does not.

b.

Immediacy requires the system to notify the user of changes immediately, while eventuality allows for delays in notification.

c.

Immediacy involves explicit user directives to make changes observable, while eventuality does not.

d.

Immediacy allows for visual representations of files, while eventuality does not.

Discuss
Answer: (b).Immediacy requires the system to notify the user of changes immediately, while eventuality allows for delays in notification. Explanation:In the principle of honesty, immediacy implies that the system notifies the user of changes immediately, without requiring any further user interaction. Eventuality, on the other hand, allows for delays in notification until the user initiates explicit directives.
Q30.
How does the visual desktop interface demonstrate the principle of honesty?

a.

By immediately notifying the user of any changes in the system's state

b.

By providing a visual representation of files and their locations in the file system

c.

By allowing the user to predict the effect of future interactions accurately

d.

By ensuring that all past interactions can be easily synthesized by the user

Discuss
Answer: (b).By providing a visual representation of files and their locations in the file system Explanation:The visual desktop interface demonstrates the principle of honesty by providing a visual representation (or icon) of files, allowing the user to easily assess the effect of past operations, such as moving a file to a new location in the file system.
