What is the primary purpose of providing feedback in human-computer interaction?

  1. To inform the user about the system's state

  2. To entertain the user

  3. To increase the system's complexity

  4. To make the system more efficient

Show answer
Correct Option: A
Explanation:

Feedback is provided to inform the user about the current state of the system, the results of their actions, and any errors that may have occurred.

Which of the following is NOT a type of feedback in human-computer interaction?

  1. Visual feedback

  2. Auditory feedback

  3. Haptic feedback

  4. Olfactory feedback

Show answer
Correct Option: D
Explanation:

Olfactory feedback is not a type of feedback commonly used in human-computer interaction.

What is the term used to describe the time it takes for a system to respond to a user's input?

  1. Response time

  2. Latency

  3. Delay

  4. Lag

Show answer
Correct Option: A
Explanation:

Response time is the term used to describe the time it takes for a system to respond to a user's input.

What is the ideal response time for a system to maintain a sense of immediacy and responsiveness?

  1. Less than 100 milliseconds

  2. Less than 1 second

  3. Less than 5 seconds

  4. Less than 10 seconds

Show answer
Correct Option: A
Explanation:

For a system to maintain a sense of immediacy and responsiveness, the ideal response time should be less than 100 milliseconds.

Which of the following factors can affect the response time of a system?

  1. Processing speed

  3. Input device latency

  4. All of the above

Show answer
Correct Option: D
Explanation:

All of the factors mentioned can affect the response time of a system.

What is the term used to describe the user's perception of the system's response time?

  1. Subjective response time

  2. Objective response time

  3. Perceived response time

  4. Actual response time

Show answer
Correct Option: C
Explanation:

Perceived response time is the term used to describe the user's perception of the system's response time.

Which of the following factors can affect the user's perceived response time?

  1. Task complexity

  2. User expectations

  3. System feedback

  4. All of the above

Show answer
Correct Option: D
Explanation:

All of the factors mentioned can affect the user's perceived response time.

What is the Hick-Hyman Law?

  1. A law that states that the time it takes to make a decision increases with the number of choices available

  2. A law that states that the time it takes to perform a task decreases with the number of times it is repeated

  3. A law that states that the time it takes to learn a new skill decreases with the number of times it is practiced

  4. A law that states that the time it takes to complete a task increases with the number of steps involved

Show answer
Correct Option: A
Explanation:

The Hick-Hyman Law states that the time it takes to make a decision increases with the number of choices available.

Which of the following techniques can be used to reduce the perceived response time of a system?

  1. Providing immediate feedback

  2. Using progress indicators

  3. Reducing the number of steps in a task

  4. All of the above

Show answer
Correct Option: D
Explanation:

All of the techniques mentioned can be used to reduce the perceived response time of a system.

What is the Fitts' Law?

  1. A law that states that the time it takes to move a cursor to a target increases with the distance between the cursor and the target

  2. A law that states that the time it takes to perform a task decreases with the number of times it is repeated

  3. A law that states that the time it takes to learn a new skill decreases with the number of times it is practiced

  4. A law that states that the time it takes to complete a task increases with the number of steps involved

Show answer
Correct Option: A
Explanation:

Fitts' Law states that the time it takes to move a cursor to a target increases with the distance between the cursor and the target.

Which of the following is NOT a factor that affects the Fitts' Law?

  1. Distance between the cursor and the target

  2. Size of the target

  3. Speed of the cursor

  4. User's skill level

Show answer
Correct Option: C
Explanation:

The speed of the cursor is not a factor that affects the Fitts' Law.
