Human Computer Interaction (IT-803 (B)) - Important Questions

  1. Unit 27 Marks High Priority

    Explain storyboarding and its role in the interactive system design process. Describe the steps to create an effective storyboard and discuss its advantages and limitations in usability engineering.

    Core topic from Unit 2; emphasized by analytics (Storyboarding frequency high).

  2. Unit 27 Marks High Priority

    What are use cases? Explain the standard structure of a use case (actor, preconditions, main flow, alternate flows, postconditions) and outline guidelines for writing clear and testable use cases.

    Core topic from Unit 2; emphasized by analytics (Use Cases frequency high).

  3. Unit 27 Marks Medium Priority

    Differentiate between a use case and a scenario. Give typical examples of each and explain when a designer should prefer one representation over the other.

    Standard differentiation question appearing in Unit 2 assessments; tests conceptual clarity between related artifacts.

  4. Unit 27 Marks Medium Priority

    Describe the process of creating personas. Explain how personas are used to guide design decisions and list criteria for evaluating the quality of a persona.

    Common Unit 2 topic on user modeling and requirements; often asked to evaluate persona creation.

  5. Unit 27 Marks Medium Priority

    Explain Hierarchical Task Analysis (HTA). Show how HTA decomposes a user goal into subtasks and discuss benefits and limitations of HTA for interaction design.

    Core task-analysis technique in Unit 2; tests ability to decompose goals into tasks.

  6. Unit 27 Marks Medium Priority

    Compare low-fidelity and high-fidelity prototypes. Discuss their respective advantages, disadvantages, cost/time considerations and the stages of design in which each is most appropriate.

    Prototyping knowledge is central to Unit 2; compares fidelity trade-offs relevant for exams and assignments.

  7. Unit 27 Marks Medium Priority

    Explain how storyboarding and paper prototyping can be used together during early-stage user testing. Describe techniques for conducting quick tests and how feedback from these methods informs iterative design.

    Integrative question linking storyboarding and prototyping techniques; assesses practical understanding of evaluation methods.

  8. Unit 210 Marks Medium Priority

    Explain how use case diagrams are constructed. Draw and label the primary elements of a use case diagram and explain the semantics of relationships such as "include", "extend" and generalization between actors or use cases.

    Standard notation/diagram question for Unit 2; requires knowledge of UML use case diagram elements and relationships.
