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

  1. Unit 114 Marks High Priority

    Define Human-Computer Interaction (HCI). Discuss the goals, scope and importance of HCI in modern computing systems.

    Core definition and scope question; highest-frequency topic in Unit 1 (aggregated heatmap).

  2. Unit 114 Marks High Priority

    Explain the nature of interaction between humans and machines. Discuss the characteristics that distinguish effective from poor interactions.

    Fundamental concept asked frequently: nature and characteristics of human-machine interaction.

  3. Unit 114 Marks High Priority

    Describe interaction design. Explain key principles of interaction design and how they guide the creation of usable interfaces.

    Core topic from Unit 1 on design principles; moderate frequency in analytics.

  4. Unit 114 Marks High Priority

    Explain models of interaction such as Norman's Execution–Evaluation cycle and Abowd and Beale's interaction framework. Illustrate how these models help in understanding and conceptualizing interaction.

    Repeated question pattern in past papers about conceptual models of interaction.

  5. Unit 114 Marks High Priority

    Discuss the role of understanding users in HCI. Describe common user characteristics, user requirements elicitation, and compare different types of interfaces (command-line, graphical, touch, voice) with respect to user needs.

    Understanding users and interfaces is frequently tested; covers user characteristics and interface types.

  6. Unit 114 Marks High Priority

    Describe User-Centered System Design (UCSD) and discuss its core concepts and evaluation methods.

    Directly transcribed from aggregated analytics (global top question). Core design methodology question.

  7. Unit 114 Marks High Priority

    Explain the Keystroke-Level Model (KLM) and compute task time for a given sequence of operators.

    Directly transcribed from aggregated analytics (global top question). Common modeling/analysis technique asked in exams.

  8. Unit 17 Marks Medium Priority

    What is heuristic evaluation? Explain the heuristic evaluation process and give examples of common usability heuristics.

    This question appears in the global top questions; focuses on evaluative methods used in HCI.

  9. Unit 17 Marks Medium Priority

    Describe cognitive walkthrough and explain how it differs from controlled experiments and usability testing.

    Frequently occurring evaluative/comparative question from past analytics.

  10. Unit 17 Marks Medium Priority

    Describe methods for data gathering in HCI such as interviews, questionnaires, observation and contextual inquiry. Compare their advantages and limitations.

    Covers data collection techniques in Unit 1; medium frequency per heatmap.

  11. Unit 17 Marks Medium Priority

    Explain mental models and metaphors in HCI and illustrate their role in interface design.

    Covers conceptual topics: mental models and metaphors are recurring themes in Unit 1 analyses.
