1. What is Human-Computer Interaction (HCI) in the context of AI?
Answer:
Explanation:
Human-Computer Interaction (HCI) in AI involves the study, planning, and design of the interaction between people (users) and computers, focusing on creating interfaces that offer effective, efficient, and enjoyable user experiences.
2. Usability in HCI primarily refers to:
Answer:
Explanation:
Usability in HCI refers to the ease with which users can use and learn to use a human-made object, particularly computer systems and software. It is a key factor in designing effective user interfaces.
3. In HCI, 'user experience' (UX) design focuses on:
Answer:
Explanation:
User experience design in HCI involves creating products (including software and hardware systems) that provide meaningful and relevant experiences to users, focusing on aspects like usability, accessibility, and pleasure provided in the interaction.
4. The term 'affordance' in HCI refers to:
Answer:
Explanation:
Affordance in HCI refers to the properties of an object that indicate how it can be used. For instance, a button designed to look clickable suggests its use to the user.
5. 'Cognitive load' in HCI refers to:
Answer:
Explanation:
Cognitive load in HCI refers to the amount of mental effort required by a user to operate and use a system. Systems designed with HCI principles aim to minimize cognitive load for greater usability.
6. In HCI, 'contextual inquiry' is a research method that involves:
Answer:
Explanation:
Contextual inquiry in HCI is a user-centered research method that involves observing and interviewing users in their actual working environment to understand how they interact with a system or product.
7. What does 'heuristic evaluation' in HCI involve?
Answer:
Explanation:
Heuristic evaluation in HCI involves reviewing a user interface based on pre-established heuristics or guidelines. It is a usability inspection method used to identify usability problems in the design.
8. 'Gesture recognition' technology in HCI is used to:
Answer:
Explanation:
Gesture recognition technology in HCI involves the ability of a system to recognize and interpret human gestures as a means of interacting with computers, thereby enabling a more natural user interface.
9. The 'Fitts’s Law' in HCI is used to:
Answer:
Explanation:
Fitts's Law in HCI is a predictive model used to quantify the time required to move to a target area (such as a button or control) as a function of the distance to the target and the size of the target.
10. 'Voice User Interfaces' (VUIs) in HCI are designed to:
Answer:
Explanation:
Voice User Interfaces (VUIs) in HCI are interfaces that enable users to interact with systems using voice or speech commands, providing a hands-free and often more accessible way of interaction.
11. In HCI, 'accessibility' primarily concerns:
Answer:
Explanation:
Accessibility in HCI involves designing systems and interfaces that are usable by people with a wide range of abilities and disabilities, ensuring inclusivity and equal access to technology.
12. 'Eye tracking' technology in HCI is used to:
Answer:
Explanation:
Eye tracking technology in HCI involves tracking and analyzing where and how users look at a screen or interface. It provides insights into user attention, focus, and interaction patterns.
13. The primary goal of HCI is to:
Answer:
Explanation:
The primary goal of HCI is to create user interfaces and experiences that are effective, efficient, and satisfying to the user, thereby improving the interaction between humans and computers.
14. 'Multimodal interaction' in HCI refers to:
Answer:
Explanation:
Multimodal interaction in HCI refers to interfaces that use multiple modes of interaction, such as combining touch, voice, and gesture, to provide a more natural and intuitive user experience.
15. 'Haptic feedback' in HCI provides:
Answer:
Explanation:
Haptic feedback in HCI involves providing tactile feedback to users, often through vibrations or other physical responses to input. It enhances the user experience by simulating the sense of touch.
16. The concept of 'affordance' in HCI was popularized by:
Answer:
Explanation:
The concept of 'affordance' in HCI, particularly the way objects communicate how they can be used, was popularized by Donald Norman, a prominent figure in the field of design and usability.
17. In HCI, 'persona' creation is a technique used to:
Answer:
Explanation:
In HCI, creating 'personas' involves developing detailed and realistic character profiles that represent different types of users. These personas help designers understand user needs, experiences, behaviors, and goals.
18. 'Usability testing' in HCI is a method for:
Answer:
Explanation:
Usability testing in HCI involves evaluating a system or product by testing it with real users. It aims to assess how easy and efficient the system is to use, identifying any usability problems and areas for improvement.
19. The 'GUI' (Graphical User Interface) in HCI refers to:
Answer:
Explanation:
The Graphical User Interface (GUI) in HCI is an interface that allows users to interact with electronic devices through graphical elements such as icons and buttons, as opposed to text-based interfaces.
20. 'Prototyping' in HCI is important for:
Answer:
Explanation:
Prototyping in HCI involves creating early versions or models of a system, which are used for user testing and feedback. This process helps in refining the design based on actual user interactions and responses.
21. The 'Five E’s' in HCI usability are:
Answer:
Explanation:
The 'Five E’s' in HCI usability refer to a system being Efficient, Effective, Engaging, Error-tolerant, and Easy to learn. These principles guide the design of user-friendly and satisfying interfaces.
22. 'Augmented Reality' (AR) in HCI is used to:
Answer:
Explanation:
Augmented Reality in HCI involves overlaying digital information onto the real world, enhancing the user's perception of reality with computer-generated sensory input like graphics, sound, or video.
23. In HCI, 'context-aware computing' refers to:
Answer:
Explanation:
Context-aware computing in HCI involves systems that recognize and adapt to the user's context, such as their location, time of day, or activity. This adaptability enhances the system’s relevance and usability.
24. The use of 'voice assistants' in HCI exemplifies:
Answer:
Explanation:
The use of voice assistants in HCI exemplifies interaction based on voice commands. Users can communicate with these systems using natural language, making interaction more intuitive and accessible.
25. 'Ergonomics' in HCI focuses on:
Answer:
Explanation:
Ergonomics in HCI focuses on the study of people's efficiency in their working environment, particularly in how they interact with computer systems and other technologies. It aims to design systems that fit the user’s physical requirements and cognitive capacities.
