Human Computer Interaction (CY-803 (C)) - Important Questions

  1. Unit 57 Marks Medium Priority Asked: 2024

    What is RFID? Explain the principle of operation behind RFID technology and how data is transmitted between RFID tags and readers.

    Direct past-paper question from Mobile and Wireless Security (Unit 5).

  2. Unit 514 Marks High Priority

    Explain usability testing. Describe the different types of usability testing methods and outline the steps to conduct a usability test for a web application. Include the metrics commonly used to evaluate usability test results.

    Core topic for Unit 5; highest frequency topic according to analytics (Usability testing). Essential long-answer question covering methods and metrics.

  3. Unit 510 Marks High Priority

    What is groupware? Discuss the characteristics of groupware systems and describe CSCW models and design issues. Give examples of synchronous and asynchronous groupware applications.

    Frequent Unit 5 topic (Groupware). Covers theory, CSCW models and practical examples.

  4. Unit 57 Marks Low Priority

    Explain Fitts' Law and derive the common formulation. Using the expression $T = a + b\log_2\left(\frac{2D}{W}\right)$ compute the movement time for $D = 80\,\text{mm}$, $W = 20\,\text{mm}$ with $a = 50\,\text{ms}$ and $b = 100\,\text{ms}$. Show all calculation steps.

    Standard HCI analytical question (global top topic). Requires derivation and numeric computation using Fitts' Law.

  5. Unit 510 Marks Low Priority

    Using GOMS/Keystroke-Level Model (KLM), estimate the time to perform the task: search for a product, add it to the cart, and complete checkout on a desktop web interface. List the KLM operators used and compute the numeric time using standard operator times.

    Global important modeling question (GOMS/KLM). Tests ability to list operators and compute task time.

  6. Unit 57 Marks Low Priority

    Explain the Model Human Processor and outline the implications of its perceptual, cognitive, and motor processor parameters for interface response time and design decisions.

    Prototype evaluation and design implication topic (Model Human Processor).

  7. Unit 510 Marks Low Priority

    Prepare a storyboard and a use-case for a sample application (for example, online shopping or mobile banking). Identify primary stakeholder profiles, key tasks, and describe the main interaction steps in the use-case.

    Design representation and requirements elicitation question (storyboard/use-case).

  8. Unit 510 Marks Low Priority

    Describe Nielsen's ten heuristics for user interface design. Explain how to conduct a heuristic evaluation on a mobile application and provide examples of usability issues that each of three selected heuristics might reveal.

    Heuristic evaluation practical question; common applied topic though not present in recent raw data.
