Which of the following is NOT a principle of usability?

  1. Visibility of system status.

  2. Consistency and standards.

  3. User control and freedom.

  4. Flexibility and efficiency of use.

Show answer
Correct Option: D
Explanation:

Flexibility and efficiency of use is not a principle of usability, but rather a guideline for designing usable interfaces.

What is the purpose of accessibility in HCI?

  1. To make the user interface accessible to users with disabilities.

  2. To ensure that the user interface is compatible with different devices and platforms.

  3. To make the user interface easy to learn and use.

  4. To reduce the number of errors made by the user.

Show answer
Correct Option: A
Explanation:

Accessibility is concerned with making the user interface accessible to users with disabilities, so that they can use the interface effectively and independently.

Which of the following is NOT a type of disability that can affect accessibility?

  1. Visual impairment.

  2. Hearing impairment.

  3. Cognitive impairment.

  4. Physical impairment.

Show answer
Correct Option: C
Explanation:

Cognitive impairment is not a type of disability that can affect accessibility, as it does not affect the user's ability to interact with the user interface.

What is the Web Content Accessibility Guidelines (WCAG)?

  1. A set of guidelines for making web content accessible to users with disabilities.

  2. A set of guidelines for designing usable user interfaces.

  3. A set of guidelines for developing mobile applications.

  4. A set of guidelines for designing websites.

Show answer
Correct Option: A
Explanation:

The Web Content Accessibility Guidelines (WCAG) is a set of guidelines for making web content accessible to users with disabilities, so that they can use the web effectively and independently.

Which of the following is NOT a principle of WCAG?

  1. Perceivable.

  2. Operable.

  3. Understandable.

  4. Robust.

Show answer
Correct Option: D
Explanation:

Robustness is not a principle of WCAG, but rather a guideline for making web content accessible.

What is the purpose of user testing in usability and accessibility?

  1. To evaluate the usability and accessibility of a user interface.

  2. To identify potential problems with the user interface.

  3. To gather feedback from users on the user interface.

  4. All of the above.

Show answer
Correct Option: D
Explanation:

User testing is used to evaluate the usability and accessibility of a user interface, identify potential problems with the user interface, and gather feedback from users on the user interface.

Which of the following is NOT a method for conducting user testing?

  1. Think-aloud protocol.

  2. Eye-tracking.

  3. Heuristic evaluation.

  4. Focus group.

Show answer
Correct Option: C
Explanation:

Heuristic evaluation is not a method for conducting user testing, but rather a method for evaluating the usability and accessibility of a user interface.

What is the purpose of a heuristic evaluation?

  1. To evaluate the usability and accessibility of a user interface.

  2. To identify potential problems with the user interface.

  3. To gather feedback from users on the user interface.

  4. All of the above.

Show answer
Correct Option: A
Explanation:

A heuristic evaluation is a method for evaluating the usability and accessibility of a user interface by using a set of predefined criteria.

Which of the following is NOT a heuristic for evaluating usability?

  1. Visibility of system status.

  2. Consistency and standards.

  3. User control and freedom.

  4. Error prevention.

Show answer
Correct Option: D
Explanation:

Error prevention is not a heuristic for evaluating usability, but rather a guideline for designing usable interfaces.

What is the purpose of a cognitive walkthrough?

  1. To evaluate the usability of a user interface.

  2. To identify potential problems with the user interface.

  3. To gather feedback from users on the user interface.

  4. All of the above.

Show answer
Correct Option: A
Explanation:

A cognitive walkthrough is a method for evaluating the usability of a user interface by walking through the interface and identifying potential problems.

Which of the following is NOT a step in a cognitive walkthrough?

  1. Identify the tasks that users will perform.

  2. Create a scenario for each task.

  3. Walk through the scenario and identify potential problems.

  4. Gather feedback from users on the user interface.

Show answer
Correct Option: D
Explanation:

Gathering feedback from users on the user interface is not a step in a cognitive walkthrough, but rather a step in user testing.

What is the purpose of a usability inspection?

  1. To evaluate the usability of a user interface.

  2. To identify potential problems with the user interface.

  3. To gather feedback from users on the user interface.

  4. All of the above.

Show answer
Correct Option: A
Explanation:

A usability inspection is a method for evaluating the usability of a user interface by inspecting the interface and identifying potential problems.

Which of the following is NOT a step in a usability inspection?

  1. Identify the tasks that users will perform.

  2. Create a scenario for each task.

  3. Inspect the interface and identify potential problems.

  4. Gather feedback from users on the user interface.

Show answer
Correct Option: D
Explanation:

Gathering feedback from users on the user interface is not a step in a usability inspection, but rather a step in user testing.

What is the purpose of a focus group?

  1. To evaluate the usability of a user interface.
