All portions of each question must be answered sequentially.] 1. a) Define the term "Ergonomics" in the context of HCI. Demonstrate the "Process of Design" by applying it to the design and development of a mouse. [Marks-5] CLO-3 Level-3 b) Discuss the concept of Screen Design and Layout. Interpret the navigation design of a smartphone app UI and assess how its structure, flow and interactive elements affect user experience, efficiency and accessibility. [Marks-5] CLO-3 Level-5 2. a) A mobile banking app allows users to check balances, transfer money, pay bills, and receive notifications. Some users are first-time mobile banking users, while others are experienced. The app runs on different devices and operating systems and must handle occasional server errors without crashing. Explain the following principles below in the context of the above scenario, providing examples for each: - Principles to support usability - Principles of learnability - Principles of flexibility - Principles of robustness [Marks-5] CLO-4 Level-2 b) State the concept of user support and task analysis in HCI and Describe different approaches to user support. [Marks-5] CLO-4 Level-2 3. a) Summarize the concepts of Cognitive Walkthrough, Heuristic Evaluation, and Review-based Evaluation in user interface design, providing a brief example for each. [Marks-5] CLO-4 Level-2 b) Design an experimental evaluation for a user interface, specifying the subjects, variables (IV & DV), hypothesis, and experimental design with proper justification. [Marks-5] CLO-4 Level-3 4. a) A hospital develops an online appointment and patient record system where doctors, nurses, and patients access data from different devices. The system must allow secure access to records, centralize data storage, and support simultaneous queries from multiple users. Based on the scenario, Select the most appropriate architectural design from "Client-Server, MVC, or PAC" for the platform. Illustrate your choice with a diagram and Explain the architecture in brief. [Marks-5] CLO-5 Level-3 b) Classify the following evaluation techniques in HCI into Observational Methods, Query Techniques and Physiological Methods, providing a brief example for each.
