Click on each question below to reveal the theory, correct answers, and exam tips!

Question 1 – Purpose of User Experience (UX) Design

Question

Which of the following best describe the purpose of UX Design?

Correct Answer

✅ (b), (c)

High-Level Theory

User Experience (UX) Design is about creating products that are easy, useful, enjoyable, and meaningful for users. UX designers study user needs, improve usability, accessibility, and overall satisfaction.

Option Explanation

❌ (a) Designing the internal logic of algorithms
This is the responsibility of software developers, not UX designers.

✅ (b) Creating a cohesive and meaningful experience for users
This is one of the main goals of UX.

✅ (c) Improving usability and accessibility
UX ensures products are easy to learn and usable by everyone.

❌ (d) Reducing server costs
This belongs to system architecture or infrastructure.

❌ (e) Ensuring coding standards
This is software engineering, not UX.

💡 Exam Tip: UX = User Feelings + User Experience + User Satisfaction

Question 2 – Difference Between UI and UX

Correct Answer

✅ (a), (b)

High-Level Theory

Many students confuse UI and UX.

• UI (User Interface): Buttons, Menus, Colours, Icons, Layout.
• UX (User Experience): Ease of use, User satisfaction, User research, User journey, Overall experience.

Think of a car: UI = Steering wheel, dashboard, seats. UX = How enjoyable and easy the car is to drive.

Option Explanation

✅ (a) UI focuses on buttons and menus

✅ (b) UX understands user needs

❌ (c) UI and UX are the same

❌ (d) UX only concerns layout (UX is much broader)

❌ (e) Database optimization

💡 Exam Tip: UI = Look | UX = Feel

Question 3 – Third HCI Paradigm

Correct Answer

✅ (a), (c), (e)

High-Level Theory

The Third HCI Paradigm studies how technology fits into real-life situations. Instead of only focusing on efficiency or cognition, it considers: Social interaction, Culture, Environment, User values, Emotions, and Context.

Option Explanation

✅ (a) Social and cultural aspects

❌ (b) Computational models of cognition (Belongs to the Second HCI Paradigm)

✅ (c) Users adapt technology in new ways (This is called appropriation)

❌ (d) Efficiency over context

✅ (e) User values

💡 Exam Tip: First Paradigm → Body | Second Paradigm → Brain | Third Paradigm → Society & Context

Question 4 – Conceptual Models

Correct Answer

✅ (a), (c), (e)

High-Level Theory

A Conceptual Model explains how a system works before designing the interface. It helps both designers and users understand: What the system does, How users interact with it, and How different functions are connected.

Option Explanation

✅ (a) High-level description

❌ (b) Eliminates user involvement (Users should always be involved early)

✅ (c) Helps users build mental models

❌ (d) Created after physical design (It should be created before UI design)

✅ (e) Helps designers plan interactions

💡 Exam Tip: Conceptual Model = Blueprint of system behaviour

Question 5 – Interaction Types

Correct Answer

✅ (b), (c), (d)

High-Level Theory

Interaction Design includes different ways users communicate with systems:

• 1. Instructing: Giving commands (Click "Print", Press Save).
• 2. Conversing: Talking with the system (Siri, ChatGPT, Alexa).
• 3. Manipulating: Directly moving objects (Dragging files, Zooming photos).
• 4. Exploring: Moving through physical or virtual spaces (Google Maps, VR games).

Option Explanation

❌ (a) Instructing means direct manipulation (Instructing is giving commands, not manipulating objects)

✅ (b) Conversing = dialogue

✅ (c) Manipulating = dragging and gestures

✅ (d) Exploring = moving through environments

❌ (e) Responding means giving commands (Responding refers to the system reacting to user input)

💡 Exam Tip: Instructing → Commands | Conversing → Talking | Manipulating → Drag & Touch | Exploring → Navigation

Question 11 – Triangulation

Correct Answer

✅ (a), (c), (d)

High-Level Theory

Triangulation uses multiple methods, data sources, or theories to improve the validity and reliability of research. It does not remove the need for participant consent.

💡 Memory Tip: Triangulation = 3 or more ways to verify data.

Question 12 – Contextual Inquiry

Correct Answer

✅ (a), (c)

High-Level Theory

Researcher observes users in their real work environment. User acts as the expert. Researcher acts as the apprentice.

💡 Memory Tip: Contextual Inquiry = Observe users where they actually work.

Question 13 – Quantitative Data

Correct Answer

✅ (a), (b), (e)

High-Level Theory

Numerical data. Can be analyzed statistically. Measures quantities, trends, and patterns.

💡 Memory Tip: Quantitative = Quantity = Numbers.

Question 14 – Affinity Diagram

Correct Answer

✅ (b), (c), (e)

High-Level Theory

Write observations on sticky notes. Group similar ideas. Find themes and relationships.

💡 Memory Tip: Affinity Diagram = Organize ideas into groups.

Question 15 – Critical Incident Analysis

Correct Answer

✅ (a), (c), (e)

High-Level Theory

Focuses on important user events. Studies errors, confusion, and usability problems. Helps improve system design.

💡 Memory Tip: Critical Incident = Important event that affects usability.

Question 16 – Grounded Theory

Correct Answer

✅ (c), (d)

High-Level Theory

A qualitative research method used to develop a new theory from collected data (Data → Theory). Involves Open, Axial, and Selective coding stages.

💡 Memory Tip: Grounded Theory = Collect Data First → Theory Later.

Question 17 – Structured Notations

Correct Answer

✅ (a), (c), (e)

High-Level Theory

Standardized ways to present information using diagrams (UML, Flowcharts, HTA). Good for structure, but misses human emotions and social context.

💡 Memory Tip: Structured Notation = Good for structure, Bad for human emotions.

Question 18 – Low-Fidelity Prototype

Correct Answer

✅ (a), (c), (e)

High-Level Theory

Simple and inexpensive model (paper sketches, sticky notes) created during early design stages to test ideas quickly and receive early feedback.

💡 Memory Tip: Low Fidelity = Low Cost = Early Design = Paper Prototype.

Question 19 – Wizard of Oz Prototype

Correct Answer

✅ (a), (c), (e)

High-Level Theory

A testing technique where users believe they are interacting with a real computer system, but a human secretly performs the system's responses.

💡 Memory Tip: Wizard of Oz = Human Pretends to be Computer.

Question 20 – Conceptual Model

Correct Answer

✅ (a), (c), (e)

High-Level Theory

A high-level description of how users will interact with a system. Main components include Interface Metaphors, Interaction Types, and Mapping.

💡 Memory Tip: Conceptual Model = Metaphor + Interaction + Mapping.

Question 21 – High-Fidelity Prototype

Correct Answer

✅ (a), (b), (d)

High-Level Theory

A prototype that looks and behaves very similar to the final product. Includes realistic layouts, colors, and interactions. Used for usability testing and client presentations.

💡 Memory Tip: High Fidelity = High Quality = Near Final Product.

Question 22 – Formative Evaluation

Correct Answer

✅ (b), (d)

High-Level Theory

Conducted during the design and development process to improve the product before it is completed. Detects problems early to save development costs.

💡 Memory Tip: Formative = Form the Design (During development).

Question 23 – Pluralistic Walkthrough

Correct Answer

✅ (a), (c), (d)

High-Level Theory

A usability evaluation method where users, designers, developers, and usability experts evaluate a prototype together step-by-step to find issues.

💡 Memory Tip: Pluralistic = Many People Review Together.

Question 24 – Controlled Evaluation Settings

Correct Answer

✅ (a), (c), (e)

High-Level Theory

Conducted in a controlled environment (such as a usability lab) where researchers manage variables to obtain accurate results and compare user performance fairly.

💡 Memory Tip: Controlled Evaluation = Same Environment + Same Tasks = Fair Comparison.

Question 25 – A/B Testing

Correct Answer

✅ (a), (c), (d)

High-Level Theory

Compares two versions of a webpage or interface (Version A vs Version B) to determine which one performs better based on metrics like click rate or conversion rate.
