Human Computer Interaction (AL-804 (D)) - Important Questions

  1. Unit 514 Marks High Priority

    Explain Task Analysis. Describe Hierarchical Task Analysis (HTA) in detail and construct an HTA for a real-world interactive task (for example, booking a train ticket online).

    Core topic; task analysis and design is the most frequent Unit 5 subject (frequency 7).

  2. Unit 510 Marks Medium Priority

    Explain the Keystroke-Level Model (KLM) and compute task time for a given sequence of operators. Show how KLM can be used to compare two interface designs.

    Frequently asked specific model question; appears in past papers multiple times.

  3. Unit 514 Marks Medium Priority

    Describe User-Centered System Design (UCSD). Discuss its core concepts, stages in the process, and common evaluation methods used within UCSD.

    Core design methodology often examined in Unit 5 questions.

  4. Unit 57 Marks Medium Priority

    What is heuristic evaluation? Explain the process of conducting a heuristic evaluation and give examples of common heuristics used by evaluators.

    A standard evaluation technique question repeated in past papers.

  5. Unit 57 Marks Medium Priority

    Explain mental models and metaphors in HCI. Illustrate their role in interface design with examples of how metaphors shape user expectations.

    Conceptual question about mental representations and design metaphors; asked multiple times historically.

  6. Unit 510 Marks High Priority

    Describe contextual inquiry and other contextual and qualitative methods used in HCI (for example, ethnography, interviews, and field studies). Compare their strengths and weaknesses for understanding user behaviour.

    Contextual and qualitative studies are high-frequency topics (frequency 5) in Unit 5.

  7. Unit 510 Marks High Priority

    Explain use-case driven design. Write a complete use-case for a specified interactive system and derive scenarios from it, describing how the use-case informs interface design decisions.

    Use-case driven design appears frequently; typical applied question.

  8. Unit 510 Marks High Priority

    Discuss major research techniques used in HCI: controlled experiments, field studies, and longitudinal studies. For each technique, explain typical goals, strengths, and limitations.

    Research techniques have moderate-to-high frequency (frequency 4) and form core theoretical questions.

  9. Unit 514 Marks High Priority

    Explain the Cognitive Dimensions of Notations framework. Select key dimensions (for example, viscosity, visibility, and error proneness) and analyse a given notation or interface against them.

    Cognitive Dimensions is a frequently examined theoretical framework (frequency 4).

  10. Unit 510 Marks Medium Priority

    Explain Computer-Supported Cooperative Work (CSCW). Discuss the design issues and challenges for synchronous versus asynchronous collaboration tools, and give interface design recommendations.

    CSCW topics occur moderately often (frequency 3) and are core to collaborative system design questions.

  11. Unit 57 Marks Medium Priority

    Discuss ubiquitous computing and its implications for interaction design. Explain concepts such as context-awareness and address associated privacy and usability concerns.

    Ubiquitous computing is a recurring topic (frequency 3) with emphasis on context and privacy.

  12. Unit 57 Marks Medium Priority

    Describe recent interaction techniques such as gesture-based interaction, tangible user interfaces, and voice interfaces. Evaluate their usability benefits and limitations for different application domains.

    New interaction techniques are an examined applied area (frequency 3).

  13. Unit 57 Marks Medium Priority

    What is a Cognitive Walkthrough? Explain the process step by step and compare cognitive walkthroughs with usability testing and controlled experiments.

    Common evaluative technique question; compared with usability testing in past papers.

  14. Unit 57 Marks Medium Priority

    Discuss programmability in user interfaces and end-user programming. Describe the benefits and challenges, and provide examples of systems that support end-user programming.

    Programmability / end-user programming appears less often but is relevant to Unit 5 topics (frequency 2).
