Introduction to Human Computer Interaction

What is the main goal of Human-Computer Interaction (HCI)?

• To design and develop efficient computer systems.

• To study the interaction between humans and computers.

• To increase the speed of computer operations.

• To design new programming languages.

What is the difference between a GUI and a CLI?

• A GUI uses text-based commands, while a CLI uses icons and menus.

• A GUI is more difficult to learn than a CLI.

• A CLI is easier to use for beginners than a GUI.

• A GUI uses icons and menus, while a CLI uses text-based commands.

What is the purpose of usability testing in HCI?

• To determine how visually appealing a computer system is.

• To determine how easy a computer system is to use.

• To determine how fast a computer system can perform tasks.

• To determine how secure a computer system is.

What is the term used to describe the study of how people interact with technology in their natural environments?

• Human Factors

• Interaction Design

• User Experience

• Ecological Validity

Which of the following is NOT a part of the user-centered design process?

• Evaluating user needs and requirements

• Prototyping and testing designs

• Implementing design changes without user feedback

• Iteratively refining designs based on user feedback

What is the purpose of personas in the user-centered design process?

• To represent the demographic characteristics of potential users.

• To provide a concrete understanding of user goals, motivations, and needs.

• To predict user behavior based on statistical analysis.

• To evaluate the effectiveness of different interface designs.

What is the difference between qualitative and quantitative usability testing methods?

• Qualitative methods use numerical data, while quantitative methods use descriptive data.

• Qualitative methods involve observing user behavior, while quantitative methods involve asking for user feedback.

• Qualitative methods are less reliable than quantitative methods.

• Quantitative methods are more effective than qualitative methods for evaluating user experience.

Which of the following is an example of a heuristic evaluation method?

• Think-aloud protocol

• Surveys

• Cognitive walkthroughs

• A/B testing

What is the purpose of cognitive walkthroughs in the user-centered design process?

• To evaluate the usability of a system from the perspective of potential users.

• To measure the efficiency and effectiveness of a system's design.

• To identify potential user errors and points of confusion in a system.

• To determine the optimal layout and organization of a system's interface.

Which of the following is an example of a cognitive bias that can affect user perception and decision-making in HCI?

• Confirmation bias

• Sampling bias

• Observer bias

• Social desirability bias
