Question 1 What term describes the field that studies the design and use of computer technology focusing on the interfaces between people and computers? A. Computer Science B. Human–Computer Interaction C. User Experience D. Software Engineering Correct: B Explanation: Human–Computer Interaction (HCI) is the interdisciplinary field concerned with designing and evaluating user interfaces. Question 2 Which of the following is NOT typically considered a core principle of HCI? A. Usability B. Accessibility C. Profitability D. Efficiency Correct: C
Explanation: Usability, accessibility, and efficiency are central to HCI; profitability is a business concern, not an HCI principle. Question 3 Who is often credited with the concept of the “memex,” an early vision for interactive information systems? A. Douglas Engelbart B. Vannevar Bush C. Alan Turing D. Ivan Sutherland Correct: B Explanation: Vannevar Bush proposed the memex in 1945 as a way to augment human memory with machines. Question 4 Which interdisciplinary domain contributes to HCI by studying how people think and process information? A. Sociology B. Cognitive Psychology C. Electrical Engineering
C. Laser Printer D. Router Correct: A Explanation: Smartwatches are wearables that require specialized interface design for small screens and gestures. Question 7 What does “affordance” refer to in interface design? A. The cost of the system B. A visual cue that suggests how an element should be used C. The memory capacity required D. The speed of system response Correct: B Explanation: Affordances are cues, like a button’s shape, that imply its functionality. Question 8 Which heuristic refers to the system keeping users informed about what is going on through timely feedback? A. Match between system and real world
B. Visibility of system status C. Consistency and standards D. Flexibility and efficiency of use Correct: B Explanation: Visibility of system status ensures users know system updates or processing status. Question 9 The first graphical user interface (GUI) was developed at which research center? A. Bell Labs B. Xerox PARC C. MIT Media Lab D. IBM Research Correct: B Explanation: Xerox PARC pioneered the Alto with windows, icons, and menus in the 1970s. Question 10 Which key principle of HCI emphasizes designing systems for people with
Question 12 Which method involves observing users in their natural environment? A. Laboratory testing B. Ethnographic observation C. A/B testing D. Heuristic evaluation Correct: B Explanation: Ethnographic observation studies users’ real-world behaviors and contexts. Question 13 In HCI, a “persona” is used to represent what? A. A programming language B. A fictional user archetype C. A system architecture D. A hardware component Correct: B Explanation: Personas are fictional characters representing target user groups to guide design.
Question 14 Which prototype type is cheapest and fastest to create during early design? A. Fully coded prototype B. Paper prototype C. Interactive digital prototype D. High-fidelity mockup Correct: B Explanation: Paper prototypes allow quick, low-cost exploration of layout and flow. Question 15 What does Fitts’s Law predict? A. Memory retention over time B. Time needed to move to and select a target based on distance and size C. Error rate in text entry D. Optimal screen brightness settings Correct: B Explanation: Fitts’s Law models pointing task time as a function of target distance and size.
Explanation: Recognition memory is easier than recall because the system shows options. Question 18 Which Gestalt principle states that elements close to each other are perceived as a group? A. Similarity B. Proximity C. Closure D. Continuity Correct: B Explanation: The proximity principle groups nearby items visually. Question 19 What is the main focus of ergonomics in HCI? A. Software performance B. Physical interaction comfort and safety C. Network security D. Data analytics Correct: B
Explanation: Ergonomics studies designing workspaces and devices to reduce strain and injury. Question 20 Which of the following is an auditory interface consideration in HCI? A. Screen color contrast B. Speaker placement and sound clarity C. Keyboard layout D. Touchscreen sensitivity Correct: B Explanation: Auditory interfaces require clear, intuitive audio cues delivered through speakers. Question 21 What concept describes users’ internal understanding of how a system works? A. Mental model B. Physical model C. System blueprint D. Data schema
D. Paper vs. digital prototypes Correct: B Explanation: A/B testing presents two variants to users to measure preference or performance. Question 24 Which measure assesses how quickly users complete a task? A. Error rate B. Task completion time C. User satisfaction rating D. Memory recall percentage Correct: B Explanation: Task completion time quantifies efficiency in HCI evaluations. Question 25 In UCD, what follows user research during the design process? A. Coding B. Requirement specification C. Marketing D. Deployment
Correct: B Explanation: After research, designers document user requirements to guide development. Question 26 Which evaluation method uses expert reviewers instead of end users? A. Usability testing B. Heuristic evaluation C. Field study D. Survey Correct: B Explanation: Heuristic evaluation relies on experts checking interfaces against usability principles. Question 27 What does the “match between system and real world” heuristic emphasize? A. Using technical jargon B. Representing concepts in familiar terms C. Minimizing hardware requirements
D. No need for recording Correct: A Explanation: Remote testing can include diverse participants without travel expenses. Question 30 Which device factor is critical when designing for mobile HCI? A. Large keyboard availability B. Small screen size and touch input C. Unlimited processing power D. Fixed orientation Correct: B Explanation: Mobile design must accommodate small touchscreens and varying usage contexts. Question 31 Which term describes repeating design cycles of prototyping and testing? A. Waterfall model B. Iterative design C. Spiral development
D. Ad-hoc implementation Correct: B Explanation: Iterative design refines products through repeated prototyping and evaluation. Question 32 In task analysis, what is documented? A. System error logs B. Steps users take to accomplish tasks C. Server configurations D. Marketing plans Correct: B Explanation: Task analysis breaks down user goals into sub-tasks and actions. Question 33 Which of these is a haptic feedback example? A. Click sound on button press B. Screen ripple effect C. Vibration when typing on a touchscreen D. Pop-up notification
Correct: C Explanation: Interviews allow in-depth exploration of individual user perspectives. Question 36 Which principle suggests grouping related elements visually? A. Feedback B. Consistency C. Proximity D. Affordance Correct: C Explanation: Proximity groups items that belong together, aiding comprehension. Question 37 Which usability metric records the number of mistakes users make? A. Error rate B. Time on task C. Satisfaction score D. Click-through rate
Correct: A Explanation: Error rate quantifies how often users make mistakes completing tasks. Question 38 What type of memory holds information currently in use? A. Long-term memory B. Short-term memory C. Procedural memory D. Sensory memory Correct: B Explanation: Short-term (working) memory temporarily stores information for immediate tasks.
